Download the MIDI and keep building in your DAW — edit notes, change instruments, and turn a rough idea into something usable.
Best For: Vocals, Piano, and Simple Melodies
Audio to MIDI works differently depending on what you're converting. For the best workflow, stick to clean recordings of a single instrument or voice. If your audio is a clean melody or single instrument, this tool is likely worth trying. If it's a dense full-song mix, expect weaker results or use stem separation first.
What Works Best
- Vocal melodies — Hummed ideas, sung hooks, acapella lines
- Piano recordings — Solo piano lines and simple chord progressions
- Simple guitar riffs — Single-note melodies and clean fingerpicking
- Samples and loops — Clean melodic samples you want to re-pitch or re-arrange
What May Need Editing
- Complex chords — Dense voicings may produce extra "ghost notes"
- Light effects — Mild reverb or delay can decrease accuracy slightly
What Doesn't Work Well
- Full song mixes — Multi-instrument mixes are extremely hard to transcribe accurately
- Heavy distortion — Guitars or synths with heavy fuzz or distortion can confuse the AI
- Beatboxing — Percussive mouth sounds won't map cleanly to notes
See It in Action: Audio In, MIDI Out
Here's what a real conversion looks like.
A clean vocal melody recorded on a phone — 8 bars, no effects, single voice.
Why it worked well: clean single-voice audio with no background instruments.
18 notes detected. Pitch and timing mapped accurately. Minor timing adjustments needed on 2 notes.
3. Result: Usable as a fast first draft
Good enough to continue editing in your DAW. Took under 10 seconds to convert. Spent about 1 minute fixing 2 note timings — much faster than transcribing by ear.
4. Best Match For:
Music producers looking to quickly capture a hummed idea into their workflow without the friction of playing it out by ear.
Note: This is meant to be a fast, editable starting point — not a final polished transcription.
Download and Edit in Your DAW
Your converted MIDI file works with every major digital audio workstation.
Once downloaded, open the .mid file in your DAW's Piano Roll. The MIDI is fully editable — change instruments, transpose, quantize timing, adjust velocity, or rearrange the entire piece. It's your starting point to build on.
Tips: Get Better Results Before You Convert
Start With Clean Audio
A dry, close-mic'd recording of a single instrument gives the AI the clearest signal. Remove background noise, effects, and reverb before uploading.
Isolate the Instrument First
Want to convert just the vocal or bass from a full mix? Converting the whole song directly usually creates a messy cluster of ghost notes. Use a stem splitter first, then upload the cleaner isolated track for better accuracy.
Keep It Simple
Single-note melodies and simple progressions convert best. Dense chords or fast runs may still need a few fixes afterward, but you'll usually save time compared with transcribing by ear.
Frequently Asked Questions
Is the audio to MIDI conversion accurate?
For clean vocal, piano, or melody recordings, the output is usually accurate enough to be worth using as a first draft. You may still fix a few notes in your DAW, but that's much faster than starting from nothing.
What audio formats are supported?
MP3, WAV, M4A, FLAC, and OGG. For best results, use clean source audio and prefer lossless formats like WAV or FLAC when possible.
Can I convert a full song with multiple instruments?
Full songs with multiple instruments are not ideal for direct conversion. For better results, isolate the instrument or vocal first with a stem separator, then convert that cleaner track to MIDI.
Is this tool free to use?
Yes. You can try the basic audio-to-MIDI conversion for free without creating an account. This is useful when you just want to test whether a melody recording is worth converting before opening a full DAW workflow.
Can I edit the MIDI file after conversion?
Absolutely. Download the .mid file and open it in any DAW, including Ableton, FL Studio, Logic Pro, Cubase, or Pro Tools. You can edit pitch, timing, velocity, quantization, transposition, and instruments.
I have Ableton or Logic. Why not just use the built-in feature?
If your DAW is already open, that can be a great option. But sometimes you just recorded a melody on your phone, got a voice memo from a friend, or want to quickly check a sample before committing to a full session. This tool is for those quick browser-first moments. It doesn't replace your DAW; it gets you there faster.
Does it work with vocals, humming, or guitar?
Vocals and humming: yes, especially for clean melody lines. Guitar: single-note phrases and clean picking usually work well, while complex chord strumming may need correction. Beatboxing is not a great fit for note conversion.
Do you store or keep my audio files?
No. Your uploaded audio is used only for the current conversion, is not stored permanently, is not made public, and is not used to train AI models. Temporary processing data is discarded after the MIDI is generated.
