What audio files come from sources like Adobe Audition?
SoX 14.4.2 reports the following supported formats:
AUDIO FILE FORMATS: 8svx aif aifc aiff aiffc al amb amr-nb amr-wb anb au
avr awb caf cdda cdr cvs cvsd cvu dat dvms f32 f4 f64 f8 fap flac fssd
gsm gsrt hcom htk ima ircam la lpc lpc10 lu mat mat4 mat5 maud mp2 mp3
nist ogg opus paf prc pvf raw s1 s16 s2 s24 s3 s32 s4 s8 sb sd2 sds sf
sl sln smp snd sndfile sndr sndt sou sox sph sw txw u1 u16 u2 u24 u3 u32
u4 u8 ub ul uw vms voc vorbis vox w64 wav wavpcm wv wve xa xi
Is one of them the Adobe Audition format?
Can you show us an example input file?

Why are you ignoring the input length?

Are those WAV files? Are they BWF files?

Better post them to some public download site.
