Please recommend an audio player for Mac that has features like
- freely available
- can play .wav files
- Adjust the playing speed (ex. 1.1x speed etc)
- (if possible) truncate the audio file (ex. removing the last 5 minutes from the meeting recording)
The VLC media player is probably best suited.
It is Free
It plays .wav (and almost 100% of anything else out there)
It shows the Playback Speed settings.
You can use
-r to change the playback rate with
afplay -r 1.1 file.wav
