Frequently asked questions

Lyro is an AI music studio that turns a description, a vocal or a beat into a finished, mixed and mastered song. It runs in the browser and includes a prompt generator, a lyric writer in 12 languages, a stem splitter, a multitrack mixer and mastering. Lyro uses two music models and picks one by the job: Google’s Lyria 3 Pro for sung lyrics, and ACE-Step 1.5 for vocal chops, tempo-locked beats and work that starts from your own audio. It is operated by RNIFY Limited, a company registered in England and Wales (company number 16749515). Accounts are for people aged 18 or over. The features page lists everything it does.

No. You can start from one sentence, such as “a warm afro house track for a sunset video, female vocal in Spanish”. The prompt generator turns it into a producer’s brief with tempo, drums, bass, chords and vocal, the lyric writer drafts the words, and Lyro picks the model. A free version of the prompt generator works from a few choices and needs no account. If you do produce, you can set the tempo, key, lyrics and model yourself, split the result into stems and take them into your own software. The short quiz at Make a song is the quickest way in.

You can start from nothing, a vocal, a beat, or both. With nothing, you describe a song and Lyro generates it. With a vocal, Lyro writes a beat around it. With a beat, Lyro adds a vocal, either singing your lyrics at the beat’s tempo and key or improvising a topline (a vocal melody). With both, you open them in the mixer, balance them and master the result. Bringing your own audio is part of the Creator plan. Each route has its own page: AI song generator, a beat for your vocal, vocals for your beat, mixing and mastering.

Lyro currently uses two music models: Google’s Lyria 3 Pro and ACE-Step 1.5. Lyria 3 Pro is the default for sung lyrics, and its output carries Google’s SynthID watermark. ACE-Step 1.5 is an open model under the Apache-2.0 licence, used for vocal chops, tempo-locked beats and the tasks that take your audio as input. Both are reached through fal.ai. The routing follows the one blind listening test we have run: one rater, seven Turkish-language briefs and three models, on 21 September 2026. Lyria 3 Pro scored 4.57 out of 5 overall and ACE-Step 1.5 scored 3.29, although ACE-Step won the vocal-chop brief. We have not tested other languages, or each genre. Read how we test for the method and its limits.

Lyro differs in three ways, and they are narrower than you might expect: it never counts or caps downloads, its mixer and mastering are included on Creator and use no credits, and it chose its model for sung lyrics with a small Turkish pronunciation test. Starting from your own audio is not a difference. Suno’s pricing page lists audio upload on every plan, adding a vocal or an instrumental to a song on paid plans, stem separation on Pro and Premier, and Suno Studio on Premier (Suno pricing page, checked 21 Sep 2026), and Udio’s Standard plan generates songs from uploaded audio files (Udio pricing page, checked 21 Sep 2026). What Lyro does with your audio is specific: it detects tempo and key in the browser, writes a beat around your vocal, or returns a vocal at your beat’s tempo and key as an isolated stem. On downloads, from 3 September 2026 Suno limits them to 20 a month on Pro and 60 a month on Premier, with no limit on exports from Suno Studio on Premier (Suno blog, 10 Aug 2026), and Udio disabled downloads of audio, video and stems after its Universal Music Group partnership (Udio help centre). Both are strong products. Both have a free tier and cost less per song, and Lyro has no free plan. See Lyro vs Suno and Lyro vs Udio for the detail.

Lyro writes and sings in 12 languages: English, Turkish, Spanish, Portuguese, French, German, Italian, Arabic, Hindi, Japanese, Korean and Russian. Quality differs between models and between languages. Turkish is the only language we have blind-tested: in one small internal test (one rater, seven briefs, 21 September 2026) Lyria 3 Pro scored 4.67 out of 5 for Turkish pronunciation, so sung lyrics go to it by default. We have not tested the other 11 languages, so judge them by ear on your first generations. AI vocals can still mispronounce a word, especially names, slang and rare words. If that happens, respell the word the way it sounds and generate again. Details are on the how we test page.

Yes. The lyric writer drafts hooks, verses and vocal-chop phrases in 12 languages, and it can tighten or translate lyrics you already have. It uses no credits: each request counts against your plan’s monthly writing-assistant allowance (30 requests on Starter, 100 or more on Creator). Lyrics are laid out with section tags such as [Verse] and [Chorus], which the music model follows when it sings. You stay in control: edit any line before you generate, or paste in your own words and skip the writer. Your own writing also matters for rights, because the US Copyright Office says human-authored elements of a work can be protected while purely AI-generated material cannot. More on the AI lyrics generator page.

Yes. Choose no vocals and Lyro generates an instrumental from your description. If the beat has to sit at an exact tempo and key, for example because you will record over it, Lyro routes it to ACE-Step 1.5, which locks to the BPM and key you set. ACE-Step is priced by length: one credit per 30 seconds with the detailed pass, or one credit per minute with the fast pass. Other instrumentals go to Lyria 3 Pro at 4 credits a track, whatever the length. On the Creator plan you can split the result into drums, bass and other stems and rebalance it in the mixer. See the AI beat maker page.

The model is shown on each track in your library. Lyro chooses it when you generate: Lyria 3 Pro by default for sung lyrics, and ACE-Step 1.5 for vocal chops, tempo-locked beats and anything built on audio you uploaded. Before you generate, you see which model is recommended and what it costs in credits. Knowing the model matters for two reasons. Lyria 3 Pro output carries Google’s SynthID watermark, and the two models have different strengths, so the model explains a lot about how a track sounds. The reasoning is under model routing in the glossary.

If a generation fails or times out, every credit it used goes back to your balance automatically, and you do not need to ask. That includes credits prepaid for follow-up steps: if Lyro sings your lyrics over your beat and the separation step fails, those come back too. You see a notice in the app, and the refund appears as its own line in your credit history. If a finished file is faulty, for example silent or cut short, contact us and we will return the credits or run it again. A track you simply do not like is not a failed generation, so it is not refunded.

Yes, and downloads are never counted or capped on any plan. Your plan sets how much you can generate, not how often you can take files home. MP3 and FLAC downloads are included on Starter and Creator, and Creator adds WAV export and separated stems. Every download of generated audio includes an ID3 tag, a machine-readable field inside the file, that declares it AI-generated. What you have downloaded stays with you if you later cancel. The pricing page lists what each plan includes.

Yes. Upload a vocal or record one in the browser, and Lyro writes a beat around it. Lyro detects the tempo and key of your vocal in the browser, then ACE-Step 1.5 composes the instruments to fit your phrasing. You get back the full mix, and your original vocal is kept on its own track in the mixer, so you can rebalance it against the new music. It costs one credit per started minute, with a minimum of 2 credits, and needs the Creator plan. A dry vocal at a steady tempo gives the best result. Details are on the add a beat to your vocals page.

Yes, in two ways. If you give Lyro lyrics, it generates a sung performance at your beat’s tempo and key, separates the vocal and returns it as an isolated vocal stem, so your beat is never altered. That costs the song generation (4 credits with Lyria 3 Pro) plus the separation (one credit plus two per started minute), which comes to 11 credits for a three-minute beat. If you give no lyrics, ACE-Step 1.5 listens to your beat and improvises a topline over it, at one credit per started minute with a minimum of 2. The improvised vocal follows the music but does not follow written lyrics. Both need the Creator plan. See the add vocals to a beat page.

Lyro analyses the file in your browser and reads its BPM (tempo) and musical key in a few seconds, before anything is generated. The new part is then made at the same tempo and key, which is what lets a generated beat or vocal line up with yours. Detection is an estimate. Tempo can come out at half or double the real value, and a key can be confused with its relative, such as C major and A minor. You can correct both before you generate. The free BPM and key finder checks any file the same way.

Yes. The stem splitter separates a track in your library, generated or uploaded, into four stems: vocals, drums, bass and other. It costs one credit plus two per started minute, so a three-minute track is 7 credits, and it is part of the Creator plan. Separation is an estimate made by a neural network, so expect some artefacts: a little reverb or cymbal left in the vocal, or thin-sounding high frequencies. Clean, sparse mixes separate best. Only upload recordings you have the right to use, because splitting a track gives you no rights in it. More on the stem splitter page.

Yes. If you already have both parts, open them in the multitrack mixer, balance them and master the result. Mixing and mastering run in your browser, so they use no credits, and they are part of the Creator plan. Each track has gain, pan, EQ, compression, reverb, delay and a tempo-synced pump. Mastering brings the mix to a loudness target in LUFS with a limiter, and an A/B switch lets you compare before and after. Because the audio is processed on your device, phones and tablets have less memory for long, many-track projects than a laptop. See the mixing and mastering page.

Lyro costs from $3 a month. Starter is $3 a month for 45 credits, about 11 songs. Creator is a slider from $19 a month for 300 credits up to $99 a month for 1,560 credits, in $10 steps: 455 credits at $29, 615 at $39, 770 at $49, 930 at $59, 1,085 at $69, 1,245 at $79, 1,405 at $89. Credits grow in proportion to the price, so the price per credit is the same along the whole slider. Teams and Ads is a custom plan by application, described on the teams page. Prices are in US dollars and billed monthly. There is no free tier and no free trial. The pricing page has the full comparison.

A song or instrumental made with Lyria 3 Pro costs 4 credits, whatever its length. ACE-Step 1.5 is priced by length: one credit per 30 seconds with the detailed pass, or one credit per minute with the fast pass. A beat under your vocal, or an improvised vocal over your beat, costs one credit per started minute with a minimum of 2. Stem separation costs one credit plus two per started minute. Cover art is automatic and free for any generation of 2 credits or more, and new art on request costs 1 credit. The writing tools, mixing and mastering use no credits. As a guide, Starter’s 45 credits cover 11 Lyria 3 Pro songs a month and Creator’s 300 cover 75. The pricing page has the full table.

Starter is for generating songs, and Creator adds the studio and your own audio. Starter ($3 a month, 45 credits) includes generation, the prompt generator, the lyric writer, your library, share pages and MP3 and FLAC downloads. Creator (from $19 a month, 300 credits) adds the multitrack mixer, vocal tools and mastering, stem separation, bringing your own vocal or beat, WAV export and 3 generations running at once. Both include a commercial licence and uncapped downloads. If you only want finished songs from a description, Starter is enough. To mix, master, split stems or upload audio, you need Creator. Compare them on the pricing page.

Yes. Plan credits you do not use carry over once, up to one month's worth, for as long as the plan stays active. So your balance at a renewal is never more than two months of plan credits: last month’s unused credits, capped at one month’s worth, plus the new month. Anything above that lapses, and carried-over credits lapse when the plan ends. Top-up credits are separate: they never expire, they are spent after your plan credits, and they stay usable after a plan ends. If you have credits left over every month, a lower stop on the Creator slider will cost you less.

Yes. Subscribers can buy a top-up at any time: 50 credits for $9, 150 credits for $26 or 400 credits for $64. Top-up credits never expire, they are spent only after your plan credits, and they stay usable after your plan ends, with Starter’s feature set. You need an active plan to buy one. A top-up credit costs about 2.5 to 2.8 times what a plan credit costs, so if you run out most months, moving up the Creator slider is much cheaper than buying top-ups. See the pricing page.

Top-ups cost more per credit because they are a one-off purchase with no commitment, and the lower rate is what a monthly plan earns. A plan credit works out at about $0.063. A top-up credit costs $0.16 to $0.18 depending on the size, which is about 2.5 to 2.8 times the plan rate. In return, top-up credits never expire and stay usable after a plan ends. If you run out most months, a top-up is the expensive fix: moving up the Creator slider is charged pro rata, the extra credits arrive at once, and you can move back down at the next renewal. The pricing page shows every stop.

No. Lyro has no free trial and no free tier. Every generation costs us real money at the model provider, and we would rather spend it on better models than on free credits. You can still judge the quality before you pay. The showcase has real tracks made on Lyro with the prompts behind them, and the AI music prompt generator and the BPM and key finder are free to use. The smallest plan is $3 a month, and you can cancel in the app in two clicks.

You change plan inside the app, from Settings, then Billing: pick Starter or any stop on the Creator slider. It takes one click, plus a confirmation when the change means a charge. Moving up is charged pro rata straight away, and the extra credits land in your balance at once. Moving down takes effect at your next renewal, which is when the lower price and the smaller monthly allowance start, and the credits you have already been given stay with you. Your library is not affected either way. The stops on the slider and their credits are listed on the pricing page.

Yes. You can pause a plan for up to 3 months, in whole months, from Settings, then Billing. While it is paused you are not charged and no new credits arrive. Your library stays exactly as it is, and the plan starts again by itself on the date shown, or sooner if you resume it yourself. A pause is also one of the things you may be offered when you start to cancel. If you expect to be away for longer, cancelling is the straightforward choice: your library is kept for 30 days after the plan ends, and downloads are uncapped, so you can save everything first.

You cancel in the app: open Settings, then Billing, then Cancel plan. It takes two clicks, with no phone call and no email. On the way you see one optional question about why you are leaving and at most one offer (a pause, the $3 Starter plan or bonus credits), which you decline with one plain button. Your plan and credits stay active until the end of the period you have paid for, and you can undo the cancellation until then. Consumers in the UK or EU who subscribed less than 14 days ago may also be entitled to a refund, explained on the cancellation and refunds page.

If you are a consumer in the UK or EU, you can cancel a new plan within 14 days for a refund, and the amount depends on whether you have used credits. At checkout you ask Lyro to start your subscription immediately and acknowledge that once you use credits you lose the 14-day right to a refund for those credits. If you cancel within 14 days and have used no credits, you get a full refund. If you have used some, the refund is reduced in proportion. A monthly renewal does not start a new 14-day period. The full rules are on the cancellation and refunds page.

Nothing is deleted when you cancel: your library is kept while your account is active, meaning it has a plan or unused top-up credits, and for 30 more days after that. We remind you by email and in the app 30, 7 and 1 days before the date. Then tracks and studio projects are deleted, and the account itself stays. Restarting a plan before the date keeps everything. Downloads are uncapped, so you can save any track first, and your commercial licence is perpetual, so cancelling does not end it. Unused plan credits lapse when the plan ends, and top-up credits stay usable.

Every subscriber has an invite link, and when a friend starts a paid plan through it you both get 20 credits that never expire. The credits are released 7 days after your friend’s first payment, provided their plan is still active on that day. You can earn at most 10 rewards a month. Inviting yourself, or someone in your own household or on your own network, is not rewarded. The link sets one first-party cookie called lyro_ref that lasts 30 days, and its only job is to credit the invite to you. It is not used for advertising or tracking.

As between you and us, you own whatever rights exist in your tracks, and Lyro claims none. We also grant you a worldwide, perpetual, royalty-free licence to use your outputs commercially, subject to our terms and our model providers’ terms. What we cannot promise is that copyright protects a track in the first place. In the United States, works generated entirely by AI are not copyrightable, and UK law on computer-generated works is under review. We also do not warrant that outputs are original or non-infringing. The plain-English version is on the music rights page.

Yes. Every paid plan includes a commercial licence, so you may release and monetise the tracks you make, subject to our terms and our model providers’ terms. The licence is worldwide, perpetual and royalty-free, which means you owe Lyro nothing per stream or per use. Two limits are worth knowing. We do not warrant that an output is original or non-infringing, and we give no indemnity, so the decision to release is yours. And platforms and distributors set their own rules on AI music. Read the music rights page before a commercial release.

Often not, and it depends on the country and on how much of the work a human made. The US Copyright Office concluded in January 2025 that works generated entirely by AI are not copyrightable and that prompts alone are not enough, while human-authored elements, selection, arrangement and modification can be protected (US Copyright Office, Copyright and AI, Part 2). In the UK, section 9(3) of the Copyright, Designs and Patents Act 1988 protects computer-generated works, but the Government’s March 2026 report on copyright and AI said that protection should be removed, and the law is under review. This is not legal advice. See the music rights page.

Yes, your licence allows it, but each platform and distributor applies its own rules on AI music. As checked on 21 September 2026, none of Spotify, Apple Music, Deezer, YouTube or TikTok bans music for being made with AI. Spotify supports voluntary AI credits, removes voice impersonation, filters spam, and leaves artist profiles that carry its AI Persona badge out of recommendations by default. Deezer tags fully AI-generated tracks and leaves them out of recommendations. YouTube and TikTok require a label on realistic AI-generated content. Distributors differ, and some reject fully AI-generated music, so check your distributor’s current policy before you upload. Be open about how the track was made: Lyro’s downloads already carry an AI-generated tag. Our policy tracker keeps a dated list with each platform’s own source, and Can you monetise AI music? covers the money side.

Yes. Every download of generated audio carries an ID3 tag, a machine-readable field inside the file, that declares it AI-generated. Tracks made with Google’s Lyria 3 Pro also carry SynthID, an inaudible watermark added by the model. Our acceptable use policy does not allow removing either mark. Article 50 of the EU AI Act, on transparency for AI-generated content, applies from 2 August 2026 (EU AI Act, Article 50). Systems already on the market before that date have until 2 December 2026 to meet its marking duty (European Commission, 24 Jul 2026). In a survey of 9,000 people, 80% wanted AI music clearly labelled (Deezer and Ipsos, 12 Nov 2025). More under AI disclosure in the glossary.

No. Lyro has no voice-cloning feature, and our rules do not allow you to imitate a real person’s voice without their documented consent, to name a real artist as a style, or to pass a track off as theirs. A real person’s voice, name and likeness can be protected by law, and the rules differ by country. Platforms act on it as well: Spotify, for example, bans impersonation. So describe the sound you want instead: tempo, instruments, vocal tone, mood. The voices you choose on Lyro are generic types, such as a soulful female or a deep male voice, not real people. See our acceptable use policy for the full rule.

Open Help inside the app and write to us: that starts a conversation with the team, and we aim to reply within one working day. The ticket carries your plan, your credit balance and your last failed job, so you do not have to explain the basics. If you have no account, or cannot sign in, the public contact form lands in the same inbox. Replies show up in the app and are emailed to you. For a failed generation you do not need to write at all, because the credits come back automatically. To report a track, use the “Report this track” control on its share page.

You get messages about your own account, which are always shown, and tips, product news and offers, which you can switch off in Settings, then Notifications. Account messages cover a failed payment, a plan that is ending, a library deletion date, a support reply or a refund. Tips and offers are on by default, as the Terms say, and have hard limits: at most 1 a day and 5 a week, never while a generation is running, and a message you dismiss stays away for 7 days, for 30 after a second dismissal and for good after a third. There are no countdown timers and no fake scarcity.

No. Lyro does not train AI models, on your uploads or on anything else. When you upload a vocal or a beat, the file is stored in your library and sent to the model provider only to process your request, for example to compose a beat around it or to split it into stems. Model inference runs at fal.ai in the USA, and files are stored with Cloudflare. Your files are private unless you switch on a share link for a track. The privacy notice lists every processor and what each one receives.

Lyro uses a short list of processors, each for one job. Cloudflare provides hosting, the database and file storage (USA and global). fal.ai runs the AI models in the USA, including Google’s Lyria model and, for the writing assistant, a language model reached through OpenRouter. Stripe handles payments. Resend sends transactional email, once that is enabled. When you choose a password, it is checked against known breaches using the Have I Been Pwned range API: only the first five characters of a SHA-1 hash are sent, never the password itself. The privacy notice has the full details.

Only people who have the link. Share pages are unlisted: they are marked noindex so search engines do not list them, and Lyro has no public feed where strangers could browse your music. Nothing is shared until you switch sharing on for a track, and you can switch it off again. Each share page has a “Report this track” control, so anyone who thinks a track infringes their rights or breaks our rules can flag it for review. How we handle reports is set out on the copyright and takedowns page.

Lyro uses no advertising trackers and no third-party analytics. It sets a small number of first-party cookies: lyro_s keeps you signed in, lyro_in is a signed-in hint, lyro_a is an anonymous analytics id kept for 12 months, and a few others remember your choices. If you arrive through a friend’s invite link, lyro_ref is kept for 30 days, only to credit the invite. Analytics run under the statistical-purposes exception in the UK’s PECR rules, in force since 5 February 2026. You can opt out at any time with the analytics switch in the footer of every page, which also removes the lyro_a cookie. The full list is on the cookies and analytics page.

Yes. From Settings you can download a copy of the data held about your account, and you can delete the account. Deleting ends any paid plan at the same moment, so there is nothing to cancel first and you are not charged again. It then erases your tracks, projects, support tickets and activity, signs you out everywhere and strips the account record of your email address and name. Unused credits are lost, and billing records are kept for as long as tax law requires. Download anything you want to keep before you delete. The privacy notice explains your rights under data protection law.
