On the contrary, don't you think i'll loose some quality in the process of decoding and encoding (that's why i wanted to stick with the 'original' format - MP 2)? 'Space' is not the most important thing to me. wav format, will i ? I mean, since the source is MP2, a lossy format. The problem here is that i won't get any improvement in sound quality by encoding the files to.
Anyway, if i can't edit compressed audio file without decompressing it first, i'll have to do as you say (that's what i was doing, actually). I thought that it was possible to edit compressed audio file without decompressing it first. Thomseye and edDV thanks for your kind help.
