Remove distortion by gain excess

[Overdrive80]

Hi, I have some audios that they have excess gain and produce distorsion when are playback. I refer to this:

If I reduce gain of this zone in 3db, distorsion disappear and all fine, but I wonder if exists any tool for do it automatically.

Thanks.

If the basic audio data is OK and you just need gain control:
Adobe Audition / Amplitude and compression effects / Hard Limiter Effect (http://help.adobe.com/en_US/audition/cs/using/WS58a04a822e3e5010548241038980c2c5-7f12.html#WSDBFD95EB-D013-44a7-A352-1109CA092EA1)
(assuming you are using Adobe Audition as shown in the screen shot)

If audio is recorded with a little clipping, it might be repairable:
Audacity Clip Fix (http://manual.audacityteam.org/man/Clip_Fix)

Thanks raffriff42, basically audio data is ok (non-clipping, source DVD), just in some parts of audio (concretally range frecuency 0-2 khz) appear this distorsion. I did read in adobe that "hard limit effect" decrease gain in overall, but I just want decrease gain in concrete frecuency areas that has distorsion. I will tried "hard limiter effect" but if I decrease value of "Maximum Amplitude", gain overall is minor and distorsion persists.

Compressors & limiters allow you to raise the overall loudness by preventing clipping on the peaks.

You mention a problem in a limited frequency range; you might want to try the multiband compressor (http://help.adobe.com/en_US/audition/cs/using/WS58a04a822e3e5010548241038980c2c5-7f12.html#WS58a04a822e3e5010548241038980c2c5-7f06) instead. It's more complicated though.

Ok, thanks. I will try it.
