Huge audio distortion when using multiple audio spectrum visualisations


#1

When I use multiple Audio Spectrum Visualisation filters on the same WAV file, I get huge audio distortion on loud sections.

The original WAV file does not have this distortion.


#2

The Audio Spectrum Visualization filter should not modify the audio in any way.

I just did a test:

  1. Open a tone clip with a 1kHz tone at 0dB
  2. Open the Audio Waveform scope and see that the audio is at maximum level
  3. Apply 4 audio waveform filters to the clip
  4. Observe that the audio level has not changed and it not clipping

There must be something else going on causing your distortion.

Questions:

  1. What version of Shotcut are you using?
  2. Have you tried applying a gain filter and reducing the gain of the audio by a few db?
