This tool can be used to apply a filter to an audio file. The filter applied is a 7th order filter of the selected kind using the configured parameters. Scipy uses these parameters to generate second-order sections and then applies them to each channel individually in the audio file.

Most audio formats are supported for input. This output format is the same as the input format, except in the case of the input being Vorbis. In that case the output is Opus when possible, otherwise wave is used for the output.
