[linux-audio-dev] [ANN] A-weighting IIR filter

If I insert the filter such way (via JACK, jack-rack):

jaaa_out - card_out - cable - card_in - THE_FILTER - jaaa_in,

how can I interpret the result in terms of SNR?

If ever you need a high precision  A-weighting filter (as used for
sound level metering), you can find one in the usual place:


The tarball contains a C++ class implementing the filter (easily
converted to C if you want that), and both a JACK in-process client
and a LADPSA plugin using it.
