Meaning of DAW

DAW: Digital Audio Workstation A workstation used in audio recording and editing. Usually consists

  • f unusually large amount of memory (max them out!), quiet,

high-speed disk storage, and inordinate amount of audio I/O. Systems capable of 10 to 24 track audio input/output is not unusual, and is one of the ways music-lovers can waste their money quite efficiently.

Meaning of DAW

DAW: Debian Audio Workstation An adventurous attempt to use Debian to perform recording and mastering with many audio tracks. It was known to be a difficult path until beginning of 2006. With improvement of real-time response times, it became popular by year 2007... (hope)

jack were born. There are frequent postings of new application annoucements also. Debian-multimedia: A mailing list for multimedia in Debian. Required for coordination for things as ladspa and jack.

Action Plans

debian-multimedia-policy: Try to come up with a plan so that applications cooperate with each other. Unify default behaviour. demudi-to-debian merge: merge packages as necessary. Things such as kernel-patch-realtime-lowlatency required in Debian main. LASH: Automating the process of starting the applications and then connecting them. Currently, it’s cumbersome. Quality assurance. Want to start adding regression testsuites. Most of applications I don’t know how to use; starting with researching the usage scenarios.
