How do you judge an EQ?

[Zaphod (giancarlo)]

I'll tell you my opinion.
The story is telling us that a linear phase eq is not always the best choice (even if some developers claims that). And that a minimum phase eq is not always the best choice. A lot of software equalizers are trying to offer an hybrid algorithm (but in general an IIR is minimum phase)

In general hardware equalizers are not completely minimum or linear phase but the phase depends on the frequency, the gain and the q, and this dependancy is difficoult to reproduce easily in software.
But Nebula, liquidchannel, liquidmix and tritone products are based on sampling.

Speaking strictly about nebula:
The good of nebula, it is based on a 64 bits path, and it is implementing raw convolution too (like liquidchannel and liquidmix) which is adding a bit of precision.
I know this last statement will not be easily accepted, but you could try by yourself:

1) in nebula you are able to revert raw convolution to a fft-based algorithm, it is even a lot lighter on CPU.
2) If someone doesn't believe the 32 vs 64 bits thingy, in nebula you are able to choose 32 bits for fft convolution (and you could test by yourself using an nvidia card and the cuda bridge asking it in our forum).
If you don't have an nvidia card, we'll add the support for fftw 32 bits asap (just ask the support in our forum).
