Hi All, First time poster to this group, please ignore my ignorance? I?m trying to use Opus 1.1 on a 400MHz MIPS 24k CPU (AR9331, specifically, like in the Arduino Yun). I?ve successfully built (I think) opus-1.1 and opus-tools-1.8 and they run, but are dog slow. opus-1.1 does have the ?enable-fixed-point option set, as this chip only has soft-float. My short test file (less than one second) encodes in 0.02 seconds o...

...recently looking into various aspects of a hardware based Icecast source, preferably open source hardware (OSHW conformant, rpi isn't), native Ethernet (USB based sucks), decent audio codec, preferably not just Line-in but also balanced inputs. I have some devices based on the Qualcomm Atheros AR9331 that use a decent Wolfson 8918 audio codec. While the codec is capable of also balanced and DMic inputs, sadly as such the devices are configured as output only. I also have, for an unrelated project, an AllWinner A10s based Olinuxino board on my desk. It at least has a line level input and native...

Hi Dean, It should work for 24kec, 34kc and 74kc cores.

Hi, In our design of Icecast2, our multiple sources will stream their high quality audio via a dedicated audio encoder (not a computer): Live audio > L+R microphone > pre amplifier > audio encoder > Icecast2 VPS So far I have a shortlist of 4 possible brands of audio encoders: Sonifex PS-SEND, Barix Instreamer, Bric-Link, Outcaster OC100. All have their pro's and cons.
