Converting mp3 to .wav is there loss of quality?

[flyn]

I need to convert mp3 to .wav so that I can edit them in adobe prem. But someone told me that there would be a loss in quality? IS is true that when you convert a .wav file to mp3 that there is some loss of quality that will carry over to when you conver it again to .wav file?t

WAV is, like avi and others, a container format. It depends on what you put in it as to what damage will be done. If you use uncompressed PCM as your format, then the WAV will sound identical to the MP3 - no further compression will be applied, and no further damge will be done.

Given that MP3 crushes the life out of anything it touches, you probably wouldn't know if there was subsequent damage anyway.

To my understanding, it goes something like this:

I - CD to Wav (no loss in quality)
II- From the previous Wav to MP3 (some loss in quality)
III- From the previous MP3 back to a new Wav (no loss in quality)

However, in spite of the fact that in there is no loss in quality in III, since you are using an MP3 that already lost some quality in II, the final Wav in III will have some degradation or loss in quality when compared the original Wav in I that came from a CD.

I hope this helps.

The decoding doesn't add more quality loss than is already there.
If you encode to mp3 to mpeg audio again after editing, there will be some additional loss.
So if you just want to cut the files, there's s free soft called mp3directcut that should do it lossless.
If your mp3 is contained in an avi and you just want to cut, you could try virtualdubmod.
Just changing the volume of an mp3 is also possible without loss, with mp3gain (http://mp3gain.sourceforge.net/).

Adobe Premiere automatically converts mp3 files to an uncompressed 44,1k file. Just Import the mp3 and lay it on the timeline.
Be careful - make sure it's in the same folder as your other media.
