Get a beat written around your vocal
Upload or record a vocal and Lyro writes a beat around it. It detects the tempo and key of your voice in the browser, then Lyro’s studio tools compose drums, bass and other instruments that follow your phrasing. They come back as a new track of instruments only. Your original vocal stays untouched on its own track, and the two play together in the mixer, where you balance them, add effects and master the result.
Plans from $14 a month for 80 credits. A beat under a 1-minute vocal costs 5 credits. No free trial. Cancel in two clicks.

How it goesThree steps
- Upload or record your vocalUse a WAV, MP3 or M4A file, or record straight from your microphone in the browser.
- Check the tempo and key, then pick a styleLyro reads both in a few seconds. Correct them if you know better, then choose a genre or describe the sound you want.
- Get the beat, then mixThe instruments are composed to your vocal and come back as their own track. They open in the mixer beside your original vocal, ready to balance and master.
The details
How it works under the hood
This is audio-conditioned generation: the model takes your recording as input, not only a text prompt. Lyro’s studio tools listen to the vocal and generate the parts that are missing, such as drums, bass, keys, percussion and synths, in the style you describe. Because it hears your phrasing, the instruments follow your timing and harmony instead of being laid over them afterwards.
What comes back is the new instruments only, as one track. Your original vocal is kept untouched on its own track, and the two play together in the mixer. That lets you bring the voice forward, process it separately, or use the instruments on their own as a backing track.
What you control
- The style: a genre, or your own description of drums, bass, chords and mood.
- The tempo and key, which Lyro detects and you can correct. Check any file with the free BPM and key finder.
- The vocal itself: the vocal tools include presets, pitch shift and time-stretch.
- The final balance, effects and loudness, in the mixer and mastering.
How to record a vocal that works
- Sing to a click or a simple guide loop in headphones, so the tempo stays steady.
- Record dry: no reverb, no echo, no music playing from speakers in the room.
- Stay the same distance from the microphone and avoid clipping, which is the harsh distortion you hear when the input is too loud.
- Leave a moment of silence before the first line, and start on the beat.
- Upload WAV if you can. A heavily compressed voice note gives the model less to work with.
Where the limits are
- Free-tempo singing, with no steady pulse, is hard to build a beat around. Expect a looser fit.
- Background music, room echo or noise in the recording confuses the detection and the model.
- Key detection can land on the relative key, and tempo on half or double the real value. Check both before you spend credits.
- The instruments will not always be what a producer would have written for your song. Plan on a few attempts and some mixing.
- Long uploads take longer to analyse and generate.
- Phones and tablets have less memory than computers for large mixer projects.
Formats, credits and rights
A beat around your vocal costs one credit per started minute, with a minimum of 5 credits, and is on every plan, Starter included. Failed generations are refunded in credits automatically. MP3 and FLAC downloads and WAV export from the studio come with every plan, and downloads are never counted or capped.
Your recording stays yours: Lyro claims no rights in what you upload or in what you make. A vocal you wrote and sang is human-authored, which matters because the US Copyright Office says human-authored elements of a work can be protected while purely AI-generated material cannot. See music rights and the guide How to make a beat for your vocal.
Questions
Does Lyro change my vocal?
No. Your original recording is kept untouched on its own track in the mixer. The generated file holds only the new instruments. You decide in the mixer how the two are balanced.
What if the tempo or key is detected wrongly?
Correct it before you generate. Tempo is most often wrong by a factor of two, and key is most often confused with its relative, such as C major and A minor. A wrong value is the most common reason a generated beat does not fit.
Can I record straight into Lyro?
Yes. You can record from your microphone in the browser, then tidy the take with the vocal tools: presets, pitch shift and time-stretch. Wear headphones while recording, so the guide track does not leak into the microphone.
What does a beat for my vocal cost?
One credit per started minute of audio, with a minimum of 5 credits, so a three-minute vocal costs 5 credits. It is on every plan: Starter is $14 a month for 80 credits. Mixing and mastering afterwards cost no credits. See the pricing page.
Do I keep the rights to my vocal?
Yes. As between you and us, you own whatever rights exist in your tracks, and Lyro claims none. Your own performance and lyrics are human-authored work. The generated instruments are covered by the commercial licence in every paid plan. See music rights.
Is there a free way to add a beat to my vocal?
Not on Lyro: it has no free plan. Free studios such as BandLab and GarageBand let you import a vocal and put loops or a beat under it, but you set the tempo and line the parts up yourself. Lyro is for when you want the instruments written to your vocal instead. See apps and AI tools that add a beat to your vocals.
How is this different from BandLab’s SongStarter?
SongStarter makes ideas from a genre, mood, tempo and key you choose, and BandLab’s help page (updated 19 Jun 2026, read 10 Oct 2026) names no way to give it your recording. Lyro starts from the vocal itself: it reads the tempo and key, and the instruments are generated with your recording as input. See can BandLab make a beat for your vocal.
