I stumbled on this thread and tried out HouseCurve. First of all, congratulations to @Greg_Wilding for creating such a useful and usable tool. Very nice. I always wanted to play around with room correction and this let me without having to buy extra hardware.
I used it with Roon following the directions. I used house curve A and it did open up the sound at the lower frequencies for jazz albums. Will have to play around more. For mid range-heavy stuff in vocals and chamber music etc, it didn’t make that much difference.
They only snag I saw was was that with DSD 128 and above files, using convolution totally overwhelmed my i7-based NUC. If I turn on sampling to PCM and then doing the convolution, it’s fine. And DSD 64 is ok without needing sampling to PCM.
I noticed that it has 8400k taps in DSD64. So when you play a DSD256 file natively, Roon upsamples to 34k taps. Currently HouseCurve is applying EQ from 30-4kHz. I guess I can lower the number of taps by lowering it to say 30-400Hz?
Has anyone else seen this problem?
