There is any program that can remove pops/clicks from mp3, without re-encode the file?

I've perceived some clicks with some musics, i've then downloaded different files (encoded with different encoders) and bitrates, the clicks are always at the same place, being a cd rip error i think

when i edit the mp3, i "fix" the problem, deleting the click, but then when i "save as" another file, it is re-encoded and file lose quality

no, you can't do it on-the-fly. the only things you can, with old and shitty programs that haven't been updated for like 7 years, is simple things like cut, trim, and fade in/out. and i don't even know if they still work with today's encoders, probably do. beyond that you'll need to convert to wav to do the changes, then encode the wav as mp3 or whatever else you want.

if you downloaded different files of the same track and the click are all in the same place, maybe they're present on the cd. food for thought. if you think otherwise see the first part.

Unfortunatelly, you have to decode to wav in order to do some editing (except the mentioned above cut/trim/fade). However, after finishing your work you can use some lossless codec (FLAC/WAVPACK/TAK etc.) to avoid further quality loss. You can also play with a combination of the new lossyWAV + FLAC to decrease even more the size, it would be interesting to post the results here.

I've done things like that using mp3directcut by cutting and/or fading in/out small portions of the track.
Apart from the cutting/fading it's a lossless process. Degree of success varies however and your chances aren't great to improve things.

If you want to or have to decode, wav edit, and re-encode I also suggest a very high quality codec for reencoding. If it is to be mp3 I suggest to encode with for instance FhG if the original was Lame encoded and vice versa.

Stop being so anal about files that you (illegally?) downloaded for free!

Choose one of the options that everyone else uses...

1. Put up with the problems
2. Fix them and re-encode the result
3. Buy the CD!

FWIW you would think that you could just re-encode the frame with the error in it, but the tools I've tried don't handle it well enough (bit reservoir issue?) to cut frames without a glitch, so this isn't possible.

For video, there is a nice tool called VideoReDo that lets you edit MPEG-2 video files and only re-encode where strictly necessary. What you want is something similar for mp3 audio files, and I don't think that exists.

Have you tried mp3DirectCut. I have used it for trimming mp3 files and it works great.

Yeah, I've used it for trimming etc too, but can it really be used to remove pops/clicks? And if not then why are you recommending it for this purpose?

Did you consider the possibility of these clicks actually being part of the music itself? When you have several different sources for the file yielding the very same clicks, this seems probable to me.

But then again ... you'll never know for sure unless you get your hands on an original ...

Yeah, sure. I wish I could get my hands on an original, but since I live in a 3 world country with proibitive taxes, I need a small fortune to afford ONE single CD that's not popular here

Without listening to the original, I will never know if it's from the disc or a rip error. Fortunately I can trim it with this program you people advised. Thanks!

If you give us the names of some of the offending tracks then someone here may have that CD and can verify if the problem is in the original or not.

Another possibility is to see if you can legally purchase and download these tracks.
