Does anyone know a good way to do this? My encoder is a bash script, so it can't be a pipes thing. I need to have it go through a temp wav file. I used FooBar for this in Windows, of course, but I'm not sure how to go about it now. Thanks!

what do you mean with "your encoder is a script"? have you looked at the debian section of rarewares?

Well you haven't given a lot of information, but maybe you're thinking of something like the script below? Of course, you could replace encode="faac..." with the commandline encoder of your choice. Another alternative would be FFmpeg, which can decode FLAC and also encode ogg/vorbis, aac, mp3, ac3, and others.

CODE

#!/bin/bash

decode="flac -s -f -o test.wav -d"
encode="faac --mpeg-vers 4 test.wav -o"

mkfifo test.wav
${decode} $1 &
${encode} $1.aac

rm test.wav

wine neroAacTag.exe "Z:/$2" -meta:artist="$3" -meta:album="$4" -meta:title="$5" -meta:track="$6" -meta:year="$7"
aacgain -r -c "$2"

you use a commandline encoder. why do you need to have a temporary WAV-file? is piping impossible anyhow?

neroAacEnc.exe uses "-" for stdin, so just use "-" as "$1", like this:

CODE

flac -d -c file.flac | you_script - file.mp4 ...

Ooo, that's good to know. Thanks!
