64 Studio Ltd. produces, integrates and documents free and open source hardware and software for media. We develop bespoke GNU/Linux distributions for our partners, package their applications for automated installation, and design embedded system hardware.
The I2S format used in the circuit board of your vintage CD player is proving very interesting as a peripheral interface for full-duplex, multi-channel audio boards on ARM devices. We have developed a new distribution for the BeagleBone Black with the lowest audio latency figures we've seen on any GNU/Linux device. Please see our presentation at Embedded Linux Conference Europe and the openMHA presentation video from this year's Linux Audio Conference for the details.
Find out how to build the software for GNU/Linux audio appliances and why we recommend Debian in this PDK tutorial video.
PiDeck is an open source hardware and Free Software project retro-fitting the Raspberry Pi onto a turntable. It's a fun project, but also an R&D testbed for realtime performance on inexpensive ARM hardware. The software is based on the armhf (ARM Hard Float) port of Debian GNU/Linux and xwax. This software is built into a custom single-purpose distribution (using PDK), which you can hack on, or just download and put on a micro SD card for your own Pi.
From 2005 we built a GNU/Linux distribution '64 Studio' which was the first multimedia workstation for the AMD64 architecture, winning critical acclaim for its stability and high performance. The best of this work can now be enjoyed in official Debian and Ubuntu releases.
