Boost your creativity and transcribe your vocal songs into sheet music. All the features of Sing2Notes: » Transcribe solo vocal recordings to sheet music » Transcribe solo vocal MP3 files to sheet music » View the transcribed music as classical score » Playback the sheet music and listen to the result » Download sheet as PDF, MIDI, or MusicXML » Share your compositions with your friends HOW DOES IT WORK? Once your music piece is uploaded, our artificial intelligence powered transcriber processes it to generate a sheet music based on what it hears. When the processing is finished, you can view the final sheet and export it in three outputs - a Midi file, a PDF engraved sheet, and a MusicXML digital note sheet. It has never been easier to convert piano pieces to sheet music! WHAT THIS APP DOESN'T OFFER » Separation of multiple instruments: The note recognition can't separate multiple instruments from your voice. If you record multiple instruments playing simultaneously you will get bad transcription results! As the name says, Sing2Notes will only work with vocal recordings. » Live note recognition: This app is not able to show you live note recognition results. Instead, it will take some time to perform the frequency analysis and shows you the final sheet music. » 100% match percentage: This app won't detect 100% of the played notes and there will also be wrong detections. But depending on the quality of the input signal, it will give you more than useful sheet! REQUIREMENTS » Internet: active internet connection for server connectivity » Microphone SUMMARY Transcribe music recordings from your microphone to sheet music. With Sing2Notes you can create on-the-go recordings of your voice. Those are uploaded to your personal songbook and transcribed to score. Musical note recognition for piano has never been so easy!

OK, but not accurate for me

I tried this to help decipher human voice singing into sheet music. It hasn’t worked very well so far, and I assumed it was my poor voice. But I tried it with a test using a brief playing of a single voice by the Unthanks (clear, perfectly in tune singing and obviously better than me!). But the result was a bit of a mess with many missed notes, even on a slow melody song, and the notes that were recorded, plus the interpreted music scale, were completely wrong. So for now, I don’t think I can use the app as it is, but I’ll keep up with any updates to see if it improves.

Spring in the music but still awsome

So I just tried this app and I think it’s kind of cool. But there is this one problem where I try to make a recording but the generated noise has a spring noise when it plays a note. I would like you to improve the AI a little (not forcing you to!)

I know how to make a song without music. I already know how I want the tune to be. Sometimes when I’m lazy about finding the tune on the piano, the app helps out a whole lot. It helps me to know what key I’m singing in and helps me to read notes to my song. It helps to add the music. Thanks for creating the app.Idea: Later you could add more instruments, and we could create our own band just singing. I love the app.

Big Disappointment.

I’ve been singing the same 20 seconds of a song directly into the app with no background noise or instruments playing repeatedly for the last 20 minutes. I tried singing it with words, on an “oooh”, closer or farther from the mic, at different tempos etc… long story short I didn’t get a single usable transcription. Like if you sing 50 notes you’ll end up with sheet music showing about 20 notes with weird gaps between them AND all of the notes are not only incorrect but they’re not even notes in the same key as each other so it’s sounds like total nonsense when played back.I’m a professional singer, and I know the problem isn’t with my pitch. This is a great idea, but it has a LONG way to go as it does not work at all. Especially If you’re new to music skip this app, it will only make you hopelessly confused.

Hi there,thank you for your honest review. Our Ai-Algorithm is still far from perfect, and we would love to improve it further with your help. I would help us a lot if you could send to us via email support@sing2notes.com your audio files and the results, so we can analyze them.

The countdown timer is now fully adjustable, allowing you to set the duration to your preference. Also, the performance of Metronome is improved.
