Audio and Video Inspector app for iPhone and iPad

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
