Jack is back!

JACK support has been out of order in Frinika for some time now - but now it's fixed using the JNAJack library by Neil C Smith.

Using JACK makes the Frinika experience on Linux much more enjoyable - and I've managed to push my 1.5 GHz Centrino laptop from 2006 down to 5 milliseconds latency.

For this to work you should run JACK in realtime mode and 128 frames. Also you must make sure that Frinika is able to go realtime.

Make sure you're member of the audio group (check /etc/groups)

and then edit /etc/security/limits.conf

and add these lines:

@realtime - rtprio 99 @realtime - memlock unlimited

(as described here)

Also remember to turn off any CPU frequency auto-scaling - as this will only cause disturbances.

Start Jack before you start Frinika - and Frinika will connect automatically to Jack.

Broadcast or record your session

In the top menu of Frinika you'll find a menu item called "Connected" where you can click further to "Radio Station". By enabling the radio station a simple web server will be started on your machine, and live audio from your Frinika session can be streamed directly from the URL http://localhost:15000/frinika.ogg

You can use the audio stream for broadcast, or just record the live audio from your Frinika session. Check out the video for a demonstration.

Exporting to WAV

After several questions on how to export to WAV from Frinika - and also since sourceforge.net has taken down the Frinika wiki (where it was explained) - I've added a simple youtube video showing you how it's done. Watch it here:
