Demo FIR filters

[mops911]

Hello

I am contemplating to jump into DRC. I use HQP and wonder how much more CPU the convolver requires.

Do filters typically come with 65k taps? And does HQP upsample it for 352k music files? Also for DSD, I understand that HQP converts to PCM, convolves and then converts back to DSD. Correct?

Could anybdy share some "neutral" or "null" filters so I can check out the additional load of HQP?

Much appreciated

You can create dummy filters with the Audiolense demo. The dummies attenuate the sound. That’s all they do.
