The purpose of the loudness filter is to compensate for the level dependency of the a human's "frequency response". Most music is mixed at pretty high levels, say at 80-90 dB SPL. If you play this bac …

This depends a lot on how you implement it. A single biquad takes about 10 arithmetic operations. (To be precise a Transposed Form II takes 4-5 multiplies and 3 adds, depending on how the gain manage …

Your channel has 3 taps, your EQ has 9 taps which means that your cascaded response has 11 taps. You only force the middle 9 taps of the response to be a unit impulse. If you convolve the channel with …

I can't run your code since one function is missing. In general, parallel EQs are a not a great idea. Since you add the responses, the exact phase responses of either boost or cut need to be carefull …

The error should be minimized between the equalized signal and what? There is no known sequence in this case. But there is: if the channel is still good enough so you can decode a packet successf …

This depends a bit on what you want to get out of this and how much effort/work you are willing to put in. Doing a room EQ that actually works and makes it sound consistently better is quite complic …

Bunch of things: Your band definition is really odd. Some of the lower bands are really small while some of the mid bands are huge. Ideally you want octaves where the band edges are 1/sqrt(2) and sq …
