Need Help -- Audio Experts

Music is available on YouTube (???) but it is containerized in a video
format.

Fortunately, with GNU/Linux, it is easy to extract.

First, determine the audio format:

ffprobe file.xxx

Usually, this will be AAC or OPUS.

Second, do the extraction:

ffmpeg -i file.xxx -acodec copy file.(opus/aac)

So far, so good.  But how can we now play the audio?

If the file is OPUS just do:

opusdec file.opus --force-wav - | aplay

Beautiful!

If the file is AAC then do:

faad -w file.aac | aplay

However this does NOT work, although according to the docs
it should.

The stdout of faad is fucked.  Most likely it is a serious bug.

This DOES work:

ffmpeg -i file.aac -f wav pipe:1 | aplay

(I omit the WAV file analysis of the two different commands.)

Can anyone confirm that the "faad -w" command is FUBAR?

If I get confirmation then I will report the bug.

Note that this DOES work:

faad -o file.wav file.acc && aplay file.wav

Only in the stdout case (-w) is the WAV file maligned.

Note: I don't want to hear any "Duh, just use VLC man" responses.
