What Sing2Notes is
Sing2Notes transcribes sung vocals into notes displayed as sheet music. You can upload an audio file, paste a YouTube link, or record music directly in the app. It can process vocals while multiple other instruments play simultaneously, and Edit Mode lets you change notes in the app. Transcriptions can also appear as a piano roll. Export formats include PDF sheet music, quantized and unquantized MIDI files, and MusicXML, which the maker says can be imported into software of your choice. Supported audio formats include MP3, WAV, MP4, MIDI, and FLAC. Sing2Notes runs in a browser and has Android and iOS apps. Free users can create unlimited demo transcriptions covering the first 20 seconds of a recording. The Pro plan allows 50 full transcriptions monthly, each up to 15 minutes, costing 14.99 USD monthly or an annual equivalent of $6.24 per month. A free trial is offered.
