Just an idea, the original sample rate of DTS is most likely 48kHz. The
target rate is 44.1kHz. These commands only have the copy codec in them:
>> $ ffmpeg -i dts_input -acodec copy -f spdif out2.spdif
>> $ ffmpeg -f s16le -ac 2 -ar 44100 -i out.spdif -acodec copy out.wav
I don't see where resampling could have happened, so my guess is that
you are basically playing 48kHz audio at 44.1kHz. The difference in
length sounds about right for that (48/44.1~=1.088).
Do you hear a change in pitch as well? Might be not that pronounced but
I think ~9% difference should be noticeable.
Best,
Peter
