It would be really helpful if the UI could display how the source audio files are encoded, such as:
- Channels: mono/stereo
- Bitrate (kbps)
- Container
- Codec
- File Size (Ideally the file size of the entire book - the size of all source files combined)
Sometimes you need to tweak the output settings to optimize for the quality of the input files, and currently it requires opening the source files in another app to find all this data.
