The audio was transcoded as a 32-bit AIFF. I need to re-encode it as a 24-bit depth leaving the format intact. According to FFMPEG (N-98498-gfa8345c) man page for -sample_fmts I can choose from the following options:
name depth u8 8 s16 16 s32 32 flt 32 dbl 64 u8p 8 s16p 16 s32p 32 fltp 32 dblp 64 s64 64 s64p 64 On 04 Sep 2020, at 13:27, Moritz Barsnick <[email protected]> wrote: > On Fri, Sep 04, 2020 at 05:27:04 +0300, Ilja wrote: >> I need to downscale 32-bit audio to 24-bit one.
