It would be worth checking which configuration is specified in statefile.yml when it errors. It would also be good to manually check the contents of the configuration file you are using when it errors to make sure it matches your expectations. One thing that I have seen is that if the rate set...

Can you expand on what you specifically mean by this? The USB gadget supports rate adjust without resampling, if you are using the same capture / playback rate you can disable resampling. If you want to resample to a different rate, you can use synchronous resampling. Difficult to say...

I am not very familiar camilladsp-setrate, but yes, it only works when using the Pi as a USB gadget, same with gaudio_ctl. CamillaDSP resampling is very good (and you can choose the quality of the resampling algorithm you want to use). You also have the advantage of being able to see if the...

If you want to stick to 96 kHz, you can use CamillaDSP to resample everything to 96 kHz. You'll still need to use a method of changing the capture sample rate (gaudio_ctl or camilladsp-setrate) to match your source file, but you can have it resample to 96 kHz in all cases. Michael

What do you mean by this? CamillaDSP is not changing sample rates? Or it is not changing to the correct FIR filter at the new sample rate? It is pretty simple to switch sample rates with a USB gadget using gaudio_ctl (https://github.com/pavhofman/gaudio_ctl). Then all you need to do is make a...

@Davide The best way I've found is to try to create the filters you want in rePhase. You can see how well the filters fit your intended target for a given number of taps (and windowing and optimization). Important to note that more taps do NOT necessarily mean more delay, it only means more...

FYI, @fabriceo uploaded aarch64 (RPi 64) versions of xmosusb and dspcreate last night. Getting it going is pretty simple. sudo apt install libusb-1.0-0-dev git clone https://github.com/fabriceo/AVDSP_DAC8 ~/AVDSP_DAC8 sudo cp ~/AVDSP_DAC8/avdsptools/rpi_aarch64/dspcreate /usr/local/bin/ sudo...

Ubuntu does not currently work with the DAC8x, try Raspberry Pi OS. Seems like a somewhat widespread issue with the RPi5, Ubuntu and DAC HATs -> https://bugs.launchpad.net/ubuntu/+source/linux-raspi/+bug/2060240. Michael

25.5 dB isn't exactly high gain, especially with a 2 V input. Just my opinion but if you don't have enough volume due to low source level, just crank the volume. I think it goes up to +18 dB? Even if you can't drive the amp to full power it still should get loud, and if it isn't loud that means...

@danstahl That is a cool device, I haven't seen it before, definitely gives you some nice options. You should be able to install minidsp-rs -> https://github.com/mrene/minidsp-rs on the Vero, which will allow you to remotely access the Device Console without the miniDSP wifi dongle. I'd...

@danstahl What is your source? Reason I ask is the Flex HT does not have bidirectional USB audio. If your source is multichannel PCM over HDMI from say an AppleTV, you can't use the Flex to route that HDMI input to CamillaDSP. Of course this isn't really a disadvantage of the Flex compared to...

Try, Lipshitz and Vanderkooy, A Family of Linear-Phase Crossover Networks of High Slope Derived by Time Delay. If you can't find it let me know and I'll send you a copy. Michael

Thanks for the info. I've been running at pretty low chunk size (128 at 48 kHz, 128 target) and I haven't noticed any issues. I don't usually use long FIR filters but I've tried some 64K tap filters and those seem to also work fine. Other than increased CPU load, is there any disadvantage to...

Sounds like commercialization of this -> https://www.audiosciencereview.com/forum/index.php?threads/review-and-measurements-of-okto-dac8-8ch-dac-amp.7064/post-536652. The readme on the GitHub has some interesting info on processing capabilities ->...
