Re: [linux-audio-user] audacity jack

Has anyone used audacity with jack successfully?

Do you know about this? I found this on the net. I haven't tried it yet, nor have I tried your suggestions.... ------- Forwarded Message [a-users] [Audacity+jack] Good news.

I tried the latest pa_snapshot-v19. I was able to run Hydrogen drum machine through jack and have audacity record the audio! So things have improved. I had to define 2 pre-processor macros to substitute for 2 Jack size functions as my Jack library is not upto date. But it did work. To make it work: 1. download the latest pa_snapshot_v19 from the PortAudio website. 2. Unpack this into Audacity-1.2.3/lib-src/ 3. Delete the old portaudio-v19 directory 3. Rename the portaudio directory portaudio-v19 4. configure audacity to build with portaudio-v19 ./configure --enable-portaudio=v19 5. build audacity make 6. optionally install audacity 7. Start the jack daemon jackd -d alsa 8. Start your jack enabled sound sources hydrogen rosegarden timidity -B2,8 -iA -Oj 9. Start a jack patch app jack-patch-bay or qjackctl 10. Ensure all jack apps have created their jack client ports. Timidity requires a midi input to be connected before it creates it's jack output port! 11. Once you have all of your Jack apps running with output ports, start audacity (portaudio-v19 enabled) Note: if you start it from the command line you will see error messages regarding access to the alsa devices 12. Open the preferences Audio I/O dialog. You will now be able to select the available jack clients as your recording source. Note: if you start up more jack clients, they are not detected by audacity. You must exit audacity and restart it to detect the new jack clients. :( Furthermore, Audacity does not open a jack input port until you hit record or play. When it does it automatically connects them with the selected input or output jack client. BUT it closes the ports when playback/record is stopped. MATT/VAUGHAN/DOMENIC: This is not how jack access should work. ports should not go away unless the client(eg audacity) is shutdown. The idea is to create them, connect them, then use them. this is may or may not be a portaudio problem. I have not looked into Audacity's use of PA and PA_JAck to determine where the fault is but it is possible that it is in EITHER audacity's use of PA or PA's use of Jack. We would greatly appreciate it if you would take a look and see IF your use of PA needs to be modified to ensure jack client longevity. I will inform the PA crowd of this as well so that they can check their side of things, if I get a chance. MARCOS: Hope this helps.
