wah wah clipping

Hi

new to this forum and audacity. really love the program and getting a handle on it. most likely a stupid question....the wah wah when i use it to process sounds it clips very badly when it gets to the higher frequencies in the sweep. i tried to do the clip fix but it didn't really make any difference. i tried the other settings in the wah perameters and that didnt seem to change it

do i need to reduce the db's of my sample prior to using the wah wah? i like the very wide sweeps where the effect is most prominet

any help would be appreciated

thanks

If you got clipping on the timeline, then you should be able to just Effect > Amplify and bring the show back down out of clipping. Audacity uses 32-bit floating format which allows that. It would not work outside of Audacity.

Reduce the volume of the whole show so it doesn't clip and then turn the volume up on your headphones or speakers. If the volume range between the quiet and loud parts of the show is too great, then you can use one of several tools like Envelope or Compressor to reduce the range. Once you get a working show and export it, clipping damage is permanent.

Yes.

Unfortunately that is not quite the case with the WahWah effect. This effect is a bit different to most other Audacity effects in that it clips at 0 dB, even if the audio track is 32 bit float. The old "Bass Boost" effect had the same problem, which was one of the reasons that it was replaced with the new "Bass and Treble" effect (which does not have this limitation).
