I have a large flac file (24bits 96kHz) A.flac containing several songs. I can extract those
bei using either sox (B.flac) or ffmpeg (C.flac) with the same splitting points:
sox T04.flac B.flac trim 22:26.342 =34:41.708
ffmpeg -i T04.flac -ss 22:26.342 -to 34:41.708 -compression_level 12 -c copy C.flac
Unfortunately, the results seem to differ in important aspects:
- C.flac that is larger (despite using "-compression_level 12")
- soxi C.flac as well as ffprobe C.flac shows the wrong lengh, namely the length of A.flac
- soxi B.flac and ffprobe B.flac show the correct length
- dr14_tmeter shows different dynamic range values for B.flac (smaller) and C.flac (larger):
DR Peak RMS Duration Title [codec]
----------------------------------------------------------------------------------------------
DR15 -2.25 dB -24.99 dB 12:15 B.flac DR16 -2.50 dB -24.99 dB 12:15 C.flac
What is going on here? Are there additional parameters in sox that can fix this?
