How to record a vocal that works
- Dry and close. Record in a small, soft room, 15 to 20 cm from the microphone. Reverb in the recording blurs the timing the tool has to read.
- No music in the background. Sing over headphones, not speakers, or the old backing leaks into the take.
- Keep a steady tempo. Singing to a click track, even a phone metronome, makes the tempo easy to detect. You can check it with the BPM and key finder.
- Start near the first word. Trim long silence at the start so the tool does not guess the downbeat from noise.
What to write in the prompt
The vocal fixes the tempo and key, so the prompt only has to describe the music: genre, drums, bass and one lead sound. For example: “Afrobeats, 104 BPM, log drum bass, shakers and congas, warm electric piano, spacious mix”. Leave out vocal words; you already have the vocal. Genre pages such as afrobeats, trap and acoustic folk list eight prompts each.
Which one to pick
- A quick sketch from a voice memo: Vocuno, AIMakeSong or Melodusk.
- You already pay for Suno: Add Instrumental is in your plan.
- You want to mix and master the result: Lyro Music keeps your vocal on its own track, with a mixer, vocal tools and mastering in the same studio.
Questions
Can AI make a beat for my vocals?
Yes. Suno (Add Instrumental), Vocuno, AIMakeSong, Melodusk and Lyro Music all take an uploaded vocal and generate music behind it, following the tempo and key of your voice.
Do I need a cappella or can I use a voice memo?
A voice memo works if it is clean. Vocuno names voice memos and demos as suitable. Background music or a noisy room makes the tempo harder to read.
How long can my vocal be?
AIMakeSong accepts up to 4 minutes, Melodusk up to 8, Suno takes uploads up to 30 minutes on paid plans, and Lyro Music makes tracks of 30 seconds to 3 minutes.
Will my voice be changed?
The tools listed here keep your recorded voice and add music behind it. Lyro Music returns your original vocal on its own track, so it is not processed unless you add effects.
Can I choose the genre of the beat?
Yes, with a prompt. Name the genre, drums, bass and one lead sound, and leave out vocal words.
Who owns the song?
Your vocal is yours. Rights to the generated music depend on each tool’s plan; Lyro Music grants commercial use on every plan. See who owns AI-generated music.
