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.
I am considering DAC2 HD with DSP-addon. One goal is to use it with a FIR-filter generated by the software Acourate.
Question: is your DSP-software already capable of operating with such a FIR filter?
Designing long FIR filters is a complex task and we won't provide any "plug-and-play" software for this. You need to understand the internals of the DSP to design a FIR filter that works perfectly. A simple copy/paste of coefficients is not a good idea. Therefore, there is no such software from us. However, if you want to learn about FIR filters, you can implement these using SigmaStudio.
Ok. Thanks for clarifying. As a free future suggestion; it might be interesting to foster whether Hifiberry may coorperate with Audiovero as the quality of their software is really above the current market.
