Audio and Video Inspector

This app supports analysing audio and video files. Initially made for transcribing and practicing music it is helpful in many other use cases, e.g. analysing a basketball game or preparing an interview for analysis in a therapy - or if you simply want to know how your cats meow sounds an octave deeper.

The main features are:
- playback and visualisation of audio and video files
- creating bookmarks in the timeline
- defining a loop range for each bookmark
- changing playback speed without changing pitch of audio
- changing pitch of audio, e.g. if audio is not in desired key or tuning differs to your instrument
- most settings and bookmarks are stored individually for each media file and can be restored later
- some features are also accessible by keyboard, e.g. play/stop, play from last position, zoom into audio waveform, navigate to next/previous bookmark, activate/deactivate loop mode, create/delete bookmark
