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!

Turn audio into sheet music with AI music transcription. Record yourself singing or playing an instrument, or import an audio file, and turn clear melodies into readable music notation you can review, play back and edit. AI Note Recognition detects notes in your recording and creates a score you can refine. Compare the original audio with MIDI playback, correct individual notes and keep working with the result. AUDIO TO SHEET MUSIC Sing, hum or play a melody into your microphone and transcribe it into sheet music. The app works with vocals and melodic instruments such as piano, guitar, violin, flute, saxophone, trumpet and clarinet. For best results, use clear melodies and single-note lines rather than dense chords or full multi-instrument mixes. With Pro, you can also import WAV, MP3, M4A and AAC audio files and transcribe recordings up to 5 minutes long. REVIEW AND EDIT DETECTED NOTES Automatic transcription can require corrections. Review and edit detected notes directly in the score. Manual note correction is available in the free version. • Change pitch by semitone or octave • Adjust note start and end timing • Delete incorrectly detected notes • Listen to changes before saving • Reset individual notes or all manual edits • Adjust the confidence level to show more or fewer detected notes SHEET MUSIC AND MUSIC NOTATION View your transcription as readable sheet music with measures, rests, accidentals, beams and ties. Choose treble clef, bass clef or both, display note names and tap the score to jump directly to a position in the recording. COMPARE AUDIO AND MIDI Switch between the original recording and MIDI playback of the recognized notes. This makes it easier to hear where the transcription differs from what you actually played, sang or hummed. FREE VERSION • Record and analyze up to 20 seconds • Save up to 3 recordings • Preview the first complete measure of the generated score • Review and manually correct detected notes PRO FEATURES Unlock Pro for a more complete transcription workflow: • Record and analyze up to 5 minutes • Import WAV, MP3, M4A and AAC audio files • View the complete generated score • Export recognized notes as MIDI • Export recordings as WAV • Adjust playback speed from 0.25× to 2.00× • Save unlimited recordings TOOLS FOR MUSICIANS Chromatic Tuner Tune your voice or instrument while viewing the detected note, frequency in Hz and deviation in cents. See whether your pitch is sharp, flat or in tune. Live Pitch Detector Follow your detected pitch in real time while singing or playing. Use it for intonation practice, melody recognition and identifying the notes you hear or play. Metronome Practice rhythm from 30 to 240 BPM. Choose different time signatures, set beat accents and use eighth-note, triplet or sixteenth-note subdivisions. FOR SINGERS, MUSICIANS AND SONGWRITERS Capture musical ideas, transcribe melodies and turn clear recordings into editable sheet music without entering every note manually. AI Note Recognition is designed for singers, pianists, guitarists, violinists, wind players, music students and songwriters who want to move from audio to notation and MIDI in one workflow.
