Zandronum

I have been using Audacity to cut and trim songs to have a natural sounding loop point, but I was wondering if there was a more efficient way of adding loop points for mp3 and ogg files. If anyone knows the answer please reply.

For Vorbis and FLAC, there is a way. But it works only in Zandronum 2.0 or anything based on ZDoom 2.5.0 or later.
How to do it

Thats a shame I was gonna try to use it on Zandronum's current build... Thanks for the reply though.
