A little guidance before you convert

Conversion uses the first audio track and cannot restore quality lost by an earlier lossy encoding. AAC uses ADTS; M4A uses AAC in an MP4 container. WAV and FLAC outputs are limited to mono/stereo, 44.1 or 48 kHz, 16-bit audio. Resampling or downmixing changes the signal; WAV to FLAC preserves samples when these settings match the input.
