For comparison I've been also testing with an OLinuXino A20 board, and
vorbis there still sits at around 85-93% cpu, however due to the
dual-core board this actually sounds mostly ok... there are still the
occasional glitches however so I wouldn't want to use this in production.
Fdkaac however sits at only 18% cpu use on the A20 board and the audio
is rock solid, even during CPU intensive activities like apt-get
updates, which is great news. At the moment my continued efforts to
build an embedded liquidsoap live encoder will be focussed around
this, or similar boards as they are just so much more capable than the
raspberry pi.
Hi,
I have more than 200 pcengine alix 3d3 with input mic modified to an
input line and liquidsoap. I use fdkaac encoder with mpeg4_he_aac
at32kbps and sound normalization. CPU usage is +/- 60% and i can run
apt-get update with "nice -n 19" :-)
