OK, I think I was barking up the wrong tree here. I guess I just need to use lib_dsp instead of sc_dsp_filters. I tried a biquad using lib_dsp and it works fine. Is there is any reason to look at sc_dsp_filters for the XCORE chips?

I tried the above code sample from @infiniteimprobability and got it to work pretty much out of the box on Linux Mint 17 with the USB 2.0 Audio Multichannel board. Thanks! I then tried to insert a biquad filter into the above code but am getting stuck there. I borrowed the build_biquad_coefficients ...

Thanks - entering the silicon as target worked for both programs. Strange that you do not see the USB MC board. Attached is a screenshot for your benefit. I did forget to mention I am doing this on Linux Mint...not sure if the build failure had something to do with that. https://s31.postimg.org/mjwk...

Hello, I am new to XMOS and have teething troubles trying lib_dsp. I created a workspace, imported lib_dsp and app_fft into it. Built app_fft successfully. Then I changed the target in the makefile to "USB Audio 2.0 Multichannel Board" (which I have) and the build fails with a whole bunch ...

Thanks, @infiniteimprobability - that is very detailed and useful info!

Hi Ross, Thanks for your reply. Of the big list of XCORE-200 processors there, would the smaller ones also be able to do 6-channel audio? So if I choose XU208 or XUF208 because they are smaller packages, and I do not need much RAM, would the firmware allow it to decode 5.1 channel USB? Would I get T...

Hello and greetings! I am new to the XMOS suite. I'm trying to select a processor for building a 5.1channel USB interface and have been going through the literature on the website. My application will use 24 bit audio at 48kHz sampling rate, and budgets are tight so I need something which does the j...
