I want to use an audio-filter with Kdenlive. So I put the treble-filter
onto my audio and see the effects parameter. No clue, what these
parameters want. A frequency-parameter "a.frequency" with a range up to
1 Mio.? And another one "a.f" with the same range? I try to gather
information.
I call
https://www.mltframework.org/plugins/PluginsFilters/
I find the filter "sox.treble", click on it and get:
https://www.mltframework.org/plugins/FilterSox-treble/
At the bottom there is the line, I#m looking for: the parameters. I
click onto this lik and get:
- 404 File not found
Where to look now? It's a SoX-filter, so I look for SoX:
http://sox.sourceforge.net/sox.html
Now, that should it be. I look for treble and get a description but no
parameters. But a line that gives me hope:
- The filters are described in detail in [1].
Ok, I goto [1] and read:
- [1] R. Bristow-Johnson, Cookbook formulae for audio EQ biquad filter
coefficients, http://musicdsp.org/files/Audio-EQ-Cookbook.txt
So, now the last step, I call
http://musicdsp.org/files/Audio-EQ-Cookbook.txt
And get:

How would you proceed?
