Re: RPi and real-time, low-latency audio

Thanks for the swappiness hint (great word swappiness:). So are we saying that swap and audio is a no-no? Also I've got dropbear on my minimal image and all seems ok (famous last words). I've done a quick search of PAM but am not really sure what itdoes and why it makes dropbear a no-go? The minimal...

Re: RPi and real-time, low-latency audio

Cool, good to know. Many thanks. I've ended up building a no gui install based on the hexxeh image http://www.raspbian.org/HexxehImages and tweaks mainly from here http://blog.extremeshok.com/archives/1081 adding alsa base & utils then jack2 (might remove and add 1 instead) and the systems way happi...

Re: RPi and real-time, low-latency audio

Hi again,

Another question...
My rpi has only 256mg of ram
"## Remount /dev/shm to prevent memory allocation errors
sudo mount -o remount,size=128M /dev/shm

I don't have that much to spare, can I set it lower somehow/where? Like would jack be happy with only 64M set here?

Cheers,

Julian

Re: RPi and real-time, low-latency audio

Hi again,

Can I ask a possibly dumb question please:
"Warning: this can cause unpredictable behaviour when running a desktop environment on the RPi"
Does this apply when using ssh and vnc?

Cheers,

Julian

Re: RPi and real-time, low-latency audio

Hi AutoStatic, This and the linuxaudio pages are super-useful, many thanks. (Apologies for the noise - I updated and upgraded before adding the repository and starting to install jack so thought this was related. Now I don't think it is) Will delete when I figure out how?? When I run this (after add...

Re: Project with D6T-44L-06 thermal sensor

Hi Dave, Thanks for chiming in (ho ho:) Cheers for the link to the video as well, hadn't seen that. Bit of background: Pure Data (Pd) is a FLOSS (Free Libre Open Source) visual coding language probably most often made use of for digital audio. More info here: http://puredata.info/ If you're on raspb...

Project with D6T-44L-06 thermal sensor

Hi all, 1st post, good to be here:) I've been working with the RPi for a few months on an audio installation I've always wanted to do. The audio part is finally working: a digital model of a windchime built in Pure Data. Taken a while but pretty much got it together. I'm now at the part where I wish...
