RTFIR - realtime convolver for Windows

[HenrikEnquist]

Wow... just wow. Makes me wanna check it. It sounds like a statement. 1.3 second delay for that filter but 2M multiplications per second?
Is it 16 bit ints ? Is there any OS running on that time ...
Sounds like very marketing-pumped numbers.

Just happened to see this. The numbers are correct and there is nothing strange with them. CamillaDSP does convolution via FFT, which transforms the expensive convolution to a much cheaper multiplication. That's how most software convolution engines (BruteFIR and EqualizerAPO to name a few other examples) handle it.

New build.
5x faster now with sse3.
Thats around 5k taps per channel for 8 channels on i7.

Who's convolver library are you using?

Now with AVX performance is around 8 x 65000 taps on i7 10700k at 48k.

Another change is that samplerate can be chosen up to 192k.
Aloso configuration is saved between runs, and two buttons to show device control panels.

Congrats, that is some serious performance improvement!

Thanks.
