Takes time and definitely not something one does ordinarily.įYI, as of this last weekend I have been able to emulate the active crossover scenario described here using: This looks unusually smooth BECAUSE it's a spatial vector average of 50 sweeps across a fairly wide area: 0.7-1m distance 20x15x5 inches LxWxH. Step response just happens to be somewhat easy to correct here given the already very good setup and alignment made beforehand.Īll other EQ filters are just simple IIR PEQs in my miniDSP - except for the HF shelving which I am now using a linear phase filter (separate profiles) for via JRiver. The most "textbook flat" looking saved correction profile preference I've done with the KH120 + Rythmik F12 sub nearfield desk setup:Ħ144 taps at used at 48kHz sampling with an ~64ms delay Not only the LFE, but even a small correction (really just a "small" nudge) with the surrounds+sub managed summed combo fixed a shallow but quite wide dip between 40-80Hz. Looks extreme but the area of concern are potential frequencies up to 300Hz The LSR305 required a single "Minimum-Phase Filters Phase Correction" centered at 1725 Hz +15 paragraphic phase EQs "only". Speakers are already "phase linear" so very little correction applied to simply match better with surround channels. Some visualization graphs of my FIR phase filter corrections: In my case, I chose to use 1 stereo filter wave file for the 44.1/88.2/176.4 kHz "family", and 1 stereo filter wave file for the 48/96/192 kHz "family". This way, for each sampling rate JRiver MC is going to play, it chooses the correct config file and the correct convolution wave file.įor option 3, I set up 2 config files for the sampling rates of 176.4/192 kHz, and had the Audio - Output Format do resampling of the different sampling rates in order to use one of the configs below.
The config files need to use a specific file name format. And finally, what I ended up using, is to set up multiple configuration files, one for each sampling rate pointing to its stereo wave file.But with the config file one can use 2 mono wave files and map so that each channel of the music uses the appropriate wave file. Same as above, it will resample all other sampling rates to that frequency specified in the config file. To use 1 configuration file, which I had to create using their tutorial, in which for 1 sampling rate you specify which wave files to use.Example: convolution filter wave file is 44.1 kHz, all the music being played, be it 48 kHz, 96 kHz or DSD64, will be resampled to 44.1 kHz during playback before using that filter wave file. All music sampling rates will be resampled to use the sampling rate of the convolution wave file.
One can go to Audio - DSP - Convolution and choose one the options below: JRiver Media Center has a very manual way of configuring it to use the convolution wave files ( see here).
