convert
Converts to FLAC, WAV at 16 or 24 bit, MP3, Opus or AAC, with sample rate, channel count and quality all settable and all reported back. What separates this from a bare transcode is the verdict on what the conversion actually did. The spectral cut-off of the source is measured first, so a source that already passed through a lossy stage is recognised before it is wrapped in a lossless container: converting an MP3 to FLAC multiplies the file size by roughly ten and restores nothing, and the.
