Audio and Video Inspector

This app helps you transcribe and practice music. You can slow down audio tracks, separate (and mute) voice, drums, bass and other instruments and much more.

The main features are:
- playback and visualization of audio and video files
- separating voice, bass, drums and other instruments
- creating bookmarks in the timeline
- defining a loop range for each bookmark
- changing playback speed without changing the pitch of the audio
- changing the pitch of the audio, e.g. if audio is not in desired key or tuning differs from 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 the last position, zoom into the audio waveform, navigate to the next/previous bookmark, activate/deactivate loop mode, create/delete bookmark
