I tried creating a loudness contour filter and it worked well. I decided to try the Quick Convolution feature. I used the file creation procedure I've used in Hifiberry OS with the DAC+DSP hat that worked well.
I created a sweep tone file in REW. I played it back through Moode and the amplifier I'm using. I recorded it in my primary listening position using a Behringer calibration mic run through a Scarlett audio interface into Audacity. The record level was set at about 70 dB. I trimmed down the recording to include only the actual audio, eliminating the parts at the beginning and end where I was working the controls.
I uploaded the file to Camilladsp in the Quick Convolution mode. I used the mono file as both left and right channels. I used the existing quick convolution pipline as a template. The configuration checked out. I tried playing back some audio. I got a huge amount of distortion. Baroque chamber music with a classic rock sound. I tried lowering the mastergain filter by 30 dB. It reduced the distortion some.
The convolution filters that came with Moode worked fine in the sense of producing undistorted audio. I'm sure I'm doing something wrong. I hope it's simple, stupid, and easy to correct. The documentation for Camilladsp doesn't directly address how to import an IR file for room correction, at least the list of instructions for dummies that I hoped to find.
