Hi, group-
I searched the forums here and finally found a post describing how to play AIFF (or AIF) files. I wanted to post a confirmation that it does indeed work, and thank the person who posted the solution, but the thread is old and in the archives.
So I'm starting a new one! Here's the solution:
sudo apt-get install sox
Then at the command line, simply navigate to the directory that your AIFF file lives in, and convert it to another format, like .WAV:
sox mysoundfile.aif mysoundfile.wav
If you have a boatload of AIFF files to convert in one directory, simply enter the directory and run a short script:
for i in *.aif; do sox "$i" "$i.wav"; done
Sox can also be tweaked with several options, but I'll leave you to the manpage for that stuff! I want to thank 3rdalbum for his/her help in the original post. The script is not from that post, but the idea to try sox is, so thanks, 3rdalbum!
I hope this helps somebody as much as it did me.
