Edit audio files with mhWaveEdit.
There are two ways to start the editor:
- During reviews, trigger the
Edit/Media/Edit audiomenu item to start the editor with the audio files of the current card. Then edit them there and save. Replay in Anki to hear the effect.
- In the card editor, click in a field with audio, that is with
[sonud:NN], and click the “W” button at the top.
You have to install the audio editor by yourself. It is a Linux program, on most distributions you should be able to install it via the package manager.
