I believe it only outputs minimum phase filters?Watch this video, it's what got me started on this:
I was under the impression that convolution was actually computationally cheap...maybe I'm mistaken?
Again, curious what your process for obtaining your convolution filters are. I have my own methods but they involve things like crude matlab scripts only I can make sense ofIt depends on what type of convolution you are doing. If you are using minimum phase IIR filters, then yes it is computationally cheap. The other advantage is low latency. This is why they are used in AVR's, MiniDSP, etc. OTOH if you are using linear phase FIR filters, especially with a lot of taps and high sample rate - then it is more expensive, but not so expensive that it would bring a modern CPU to its knees. FYI I am doing 8 channels of linear phase FIR with 131k taps at 96kHz on my i9-9600K. CPU usage is about 5%, and that same PC is also running JRiver, Acourate Convolver, and several browser windows.
Change division so that is less regarding dips max +2 dB. VBA is very useful and so is initial alignment and you can play with the phase if you wish. It's meant to preserve impulse response regarding time domain quality.Again, curious what your process for obtaining your convolution filters are.

Please excuse my ignorance, I’m still learning this stuff, but...I believe it only outputs minimum phase filters?
Those are very short compared to what I'd usually like to convolve (BRIRs for headphones)
Binaural Room Impulse Response.Please excuse my ignorance, I’m still learning this stuff, but...
what's a BRIR ?
the sxfi amp/ DAC is capable of convolving 7 channelscan't compare a phone CPU to what we find in a DAC
... just not with a custom impulse response, right?the sxfi amp/ DAC is capable of convolving 7 channels
Doesn't change the fact, that convolution is possible with a DAC.... just not with a custom impulse response, right?![]()
It takes file imports, just in their own format?Doesn't change the fact, that convolution is possible with a DAC.
Unfortunately creative is limiting it to their own format, so you can't use a sofa or .wav file as an impulse response
