I'm trying to edit a mp3 file and I have to decompress it in to wav, and I'm wondering if I compress it back to mp3, the quality of audio worsens.
Thanks

Yes, always. You have a lossy encoded file, decoding to a wave file of the same quality, then run it through another lossy encoder. Quality would have been lost in both the original encoding and again in the second encoding.

encoding into a wav probably wont result in quality loss, but the 2nd encoding to mp3 will

What do you mean by "trying to edit"?
In case you only want to create an excerpt or cut out advertisement and so on you can avoid decompressing/recompressing by using software like mp3DirectCut which cuts MP3s directly.It's also capable of fading in/fading out, here is the link

Thanks for the replies. By saying "edit", I meant EQing. Is it possible to EQ without decompressing the file? I usually use sound forge and EQ musics pretty deeply.
