Someone, I can't recall who, mentioned a few weeks ago that Arch was better for CPU usage over the standard Raspian distro, but I'm curious if anyone has found any particular version to provide the best overall performance with Csound. 

Thanks

Hello Dominic,

How much are you overclocking the RPi by? I know a few people pushing it quite far with added heatsinks with no ill effects so far, but they're not doing intensive audio work. 

I'm actually designing my own DAC for it at the moment using a TI IC. The eventual plan is to release it as both a diy kit and a built product in small numbers, it was purely personal but I've been asked about it so much it makes sense to open it up to others. 

I'm going to try a few of the available distros but am curious what others have found good so far. 

Thanks

Hello Dominic,

I use Raspbian Wheezy with modest overclocking. Of course the analog output is only 11 bit so a USB audio device is highly recommended.

Here are some tips for getting the most out of audio on the RPi:

To those using Csound on a Raspberry Pi, which version of Linux have you found to give the best overall performance?

I'm using 800 MHz, the first step after the standard 700 MHz, but I have no data how this improves things.

And I'll be sure to post to the list as soon as my DAC is ready, looking like it'll be mid to late February with my current projects. The DAC isn't the issue as I've built them before, it's the driver that's going to take time as I've never written one from scratch before. That said I've got some great resources and some good example generic drivers and code to work from. 

Thanks again

Raspian (the default raspberry Pi OS) is a port of Debian for the Pi. It is quite a stable distro, and most documentation found online is for the Pi uses Raspian. It  works fine for me and is the one I use (for now!)

I have the CCRMA Satellite release, and I like it, but I haven't yet had a chance to dig into real-time performance, or to look at performance very much in general. But it's a distro oriented towards making electronic music, so it has a lot of good tools, and it is intended for use in installations and in conjunction with Arduino.

Cheers for all the comments everyone. Very helpful.

Arch Linux has the distinction of using systemd, which is a new way of handling services. The advantage is that the bootup time is quite fast on the Pi. Documentation can all be found on the Arch wiki. 

Apparently there is also a CCRMA pi image you can download and use. This would probably have the realtime kernel for better audio performance. Not sure about this one...

It was pretty straightforward as I recall (I can't go look at the moment). The main thing I had to do was to edit /etc/apt/sources.list so I could do "apt-get build-dep" to install the Csound dependencies. If you haven't done this before, just edit the file as root, duplicate the first (probably only) line, and on the duplicated line change "deb to "deb-src".
