I've been messing around with REW / RePhase / HOLMImpulse etc. for a while now.
I've been able to create filters to my liking that I can use with EqualizerAPO on my laptop, but I haven't been able to get them into a (text) file format that DSPToolkit understands.
I assume the idea of the DSP was to be able to run FIR filters - has anyone been able to convert the usual Stereo WAV FIR filter impulse response output by RePhase or any other program in a way that DSPToolkit actually accepts?
I like to use FIR Filters, too. My goal is to use the Beocreate board as amplifier for a three way active sound system together with raspberry pi. The filters are FIR filters generated with acourate (comercial program but very powerful) Filtering can be done with bruteFIR on the raspberry pi. I just bought the beocreate board and haven't tested till now. But I don't find any guide in setting up the standard raspberry pi 3 or 4 with operating system raspbian to work together with beocreate. My idea is to use beocreate as a four channel soundcard without using the DSP. Is that possible?
I know that probably the kernel must be recompiled for having more than two audio channels.
DSPToolkit can be installed on Raspbian quite easily:

The Raspberry Pi's sound interface is two channel only. The hardware simply doesn't support 4 channels. Therefore filtering has to be done on the DSP.
