eeepc as a linux audio workstation

A few days ago I told you about the first steps into using an eeepc as a real-time audio tool. jack runs up fine. I chose the internal audio card with the combination 48kHz,  256frames, 4buffers (which gives a latency of  21.3msec) and running on its  own  it doesn’t cough up any xrun.

I couldn’t get sooperlooper working yet. Sooperlooper works (see solution)! freqtweak works  (A nice little thing!), too.  Ardour works very nice, too. Sometimes the screen is a bit small for the whole window, but  I was using ardour a bit today and it wasn’t too much of  a hassle. Audacity is buggy (converting to mono + playing results in a segmentation fault).

I will try and find out about sooperlooper and audacity. Other programs and how an external audio card  connects  (I hope  my older posts will tell me what to do), a midi interface and all that will come up soon…


a real-time kernel on a netbook

As I hoped it would be I can now give you some good news about using a real-time kernel on an ATOM platform. Basically: it works!

I bought an eeepc 1000h, one of those small laptops, which has an N270 chip from intel, 1GB of memory and a 160GB hard disc. I thought, this cannot have much less performance than my old laptop (see the About-page). I have an ubuntu 8.04 installed and usually run the linux-eeepc kernel.

To have good audio performance, I installed the real-time kernel from the 8.04  repositories and did what I wrote in the first post. Then I started the jack daemon with “/usr/bin/jackd -R -dalsa -dhw:0 -r48000 -p1024 -n2” and it worked quite well. I expected a lot of problems, but no. For some cutting, single track recording or trying bits and pieces it should be okay. I’ll give it a go and will try it out more. With an external audio card it could even be better…

So this is not bad. What the standard real-time installation still misses is a working  network. The camera and special keys do not do anything either. But I think, for the moment, this does not really matter.
