Tony is a free, open-source application for Windows, Linux, and Mac, designed for high quality pitch and note transcription for scientific applications. It is designed primarily for use with solo vocal recordings.

There are three steps to transcribing using Tony:

Automatic visualisation and sonification
First, Tony automatically analyses the audio to visualise pitch tracks and notes from monophonic recordings. You can play back pitches and notes alongside the recording, which makes it easy to spot any extraction errors.
Easy correction
Then you can use several tools that make correction of such errors a breeze, including alternative pitch track selection, octave shift, and easy note split, merge and deletion.
Export
Finally, you can export pitch track and note track in .csv (comma-separated values) format, or simply save a session file to continue annotating another time.
