mp3 to wav to mp3 quality loss?

I would like to remove parts of an mp3 file. My idea is to convert
the mp3 to wav, then use wavecorr to cut out the unwanted parts
and then use a mp3 encoder to get the cleaned-up mp3 file.
I'm just wondering if this would result in a loss of quality or not.
Does anyone know?

In particular, the BBC made all Beethoven symphonies available
in mp3 format, but each file starts and ends with a lot of spoken
advertising which I would like to delete.

If double conversion is not advisable, is there a better way to achieve
the same result.

Hi Jacques;
There is a free program called 'mpTrim' that can do what you are looking for. It works directly in mp3 format and should not affect the sound quality. It is available here:

Thanks for both your replies. I wasn't too happy with MPTrim's
user interface, until I tried FlexMusic which looks completely
hopeless. An excellent experience to appreciate WaveCorr even
more!

If it is true that a conversion from MP3 to Wav, then some editing
in the WAV-file (e.g. using WaveCorr) followed by a conversion
back to MP3 does not reduce the sound quality at all, then I won't
need mpTrim nor FlexMusic.

Another free MP3 editing utility you could try.

http://www.nch.com.au/wavepad/index.html

This appears to be the cut-down freeware taster version of a commercial program and the screenshots look promising but I haven't tried it myself.

It is very easy to cut and trim either a wave or an mp3 file using the free program, Audacity

Hi Jacques. I would not think you would lose any mp3 quality going to wave files. I am not sure about converting back to mp3. I recently did 13 one hour brodcasts as wave files (13 cds) then discovered I could put all 13 cds on one cd if I used mp3. I used the free "real audio" or "music jukebox" to do the wave to mp3 conversion. With the 78's I could hear little difference between wave and mp3 but with a good clean original I would not be so confident. (corrected aug 14)
