Audio hardware profiles - any implementations

Post by nick87720z »

It's long time as I dreamed something similar to color correction (colord, oyranos), utilizing graphic device profiles. But for audio hardware.
If any standard for audio profiles existed, I guess it should include all frequency response info, including non-linearities (for most exact idea - there could be set of different FR for various amplitudes). One time I asked about such system without any response.

I found example, how to improve laptop sound, in pulseeffects manual. And also got Defender USB Audio to compensate broken jack port, yet way better than laptop speakers. Although my first enhancement chain was for laptop speakers, I found that usb audio also could benefit, thanks to calf bass enhancer. It's also interesting, that pulseeffects prefers calf effects even where others could be used (for less cpu load), so here is also setup for calfjackhost.

My setup, adopted from pulseeffects manual: bass enhancer -> HPF -> limiter. Of course, if there are non-linearities in frequency response, this chain will not handle them. Not completely sure if EQ profiling necessary for my interface or could be done with bare ears (I hope, my ear FR is enough reliable for that :lol: ).

Would be great if collection of such setups could be made for various interfaces and monitors (not mandatory professional) or at least their combinations (when both interface and monitor make changes, which are hard to split).

P.S. I'm not sure, what group is better for such topic. Also I mentioned by project not so long before, but it was about known linux software for windows (I can understand, why it would not get any responses :lol: ).

Hi, my two cents.

You (we?) could use LSP profiler to measure the impulse response (and hence frequency response) of the soundcard: https://lsp-plug.in/?page=manuals&section=profiler_mono

As for nonlinear characterisation, that is actually far more complex than I anticipated when sitting down thinking about nonlinear profiling. Good thing that most modern hardware really is very linear.
