I am using Ubuntu Studio built on Ubuntu Dapper Drake following the guide on the Ubuntu Studio site... (the old guide as they plan to make it a separate distribution a la Ubuntu Christian Edition).
I have got Jack audio server to work with a Creox (a program for adding effects to audio input from a guitar). I get sound out of my speakers but I cant seem to be able to record the output. Ubuntu Sound Recorder doesnt work with Jack and I cant configure that using the the GUI tools. Audacity doesnt detect any sound server Jack, ALSA or otherwise, Ardour is quite plainly a maze of a program, QARecord doesnt have any kind of preference settings in the GUI and doesnt detect the output from jack, etc etc. The closest I have got is JACK TimeMachine which seems to be the only recording program detected by Jack (I am using JACK Audio Connection Kit). However, the output file is in .w64 format. And I cant play this file even using VLC player.
What am I doing wrong? Any pointers, help, anything... I have been at this on and of ever since Dapper Drake came out... If you need more info just say the word... and how to obtain the info... ie which file to check or what to run on terminal.
You'll need other programs that can also use Jack to record from programs that use Jack. You'll probably also have to 'connect' Creox to that other program, a good gui for connecting programs with Jack is qjackctl .
I'm not sure what programs Ubuntu has that come with Jack support though.
of all the recording applications i mentioned only the Ubuntu sound recorder does not come with ability to connect to Jack. the rest do... and all are found in the ubuntu repositories. I have worked around the problem like i usually do... and have not really fixed it... or done things the way I wanted to initially... I found a player for the .w64 files created by Jack TimeMachine... and it is called sweep. .w64 files are basically .wav files which are not restricted by the 2Gb file size limit. so they are quite large. about 100Mb for 5 mins of recording. fortunately sweep can convert these behemoths to .ogg or .flac files which are my preferred formats. the .flac encoding is a little buggy... with some strange clicks and screeches whenever the sound gets too loud.. i'm happy with .ogg for the moment.
encoding on the fly to .ogg or .flac is my ultimate aim... so this discussion i hope doesn't end here... more comments and suggestions are most welcome.
