[linux-audio-dev] Linux Audio Experiences

by Dan Harper

Hi all (sorry for the cross-post, but this may not be just a problem with Ardour), Over the last week and the weekend, I took to recording a song in full using Jack, Hydrogen, Ardour and Jamin. I'm not sure if Ardour/LAD is the best place to send this, but some things that I noticed may be across different software, but I thought I'd list a few issues that came up, as well as some delights. I'm not on the Jack or Hydrogen lists, but if this is a Jack or Hydrogen problem, please let me know and I'll post it there. The main problem I had was the sync between Hydrogen and Arodur. I had Hydrogen set as Jack transport slave, and Ardour as master. Both programs were set at 130 bpm, but if I recorded something to a track in Ardour, and then played it back, it sounded fine (in time), but on the screen, the recorded material does not line up with the bar lines in Ardour. The recorded stuff appears a few millimetres before the bar line. Another interesting thing was if I changed the (period?) in Jack from 512 to 1024, the Hydrogen playback was out of time to the Ardour playback, if I switched it back to the original setting it was recorded in, it was fine. I had a few stability problems, but I didn't test them very much, it seemed to be realted to having certain plugins enabled in Ardour. Jack was kicking Ardour out when a particular plugin was being used. I'll have to test that another time to get more detail. Overall though, things went fairly smoothly. The result of the weekend is available at http://danharper.org/songs.php if anyone is interested. It was all done in Linux: HYDROGEN -> ARDOUR ------------------------> JAMIN -> QARECORD Electric Guitar (3 tracks) Vocals (3 tracks) Bass Guitar Vocals Bus Hydrogen Out to an Ardour Bus Master Bus Feel free to give feedback on the song, mix, and mastering. One thing that I loved was Jack. Getting a nice sounding mix and master was so easy because I could change a track level in Hydrogen, and immediately hear the results through Jamin. Same also if I needed to change a plugin parameter or track level in Ardour, the results were immediate. There is no other set of audio tools around that I know of that can do this. A very powerful and useful feature of the design of Jack and its clients. Overall, I should mention that the majority of my time was spent wrestling with LADSPA plugins. Some cased reliability issues in Ardour (see above, more info to come). Some gave me some OK sounds, but I have noticed in the mixdown that the guitar orverdrive doesn't have a nice warm sound. I can't recall the exact plugins I used from memory, but I did find it hard to find plugins that would give me a nice warm sound on guitar tracks. Maybe that is something to improve upon. Dan

[linux-audio-dev] Re: ICMC 2004 submission deadline nearing soon

by Juhana Sadeharju

>The University of Miami is pleased to announce the general call for >submissions to ICMC 2004, to be held 1-6 November in Miami, Florida USA. Hello. Will these papers be freely available in PDF format? E.g., just like DAFX papers are. There are many interesting ICMC papers published during last 20 years, but the papers seems to be only available for a rich man. Could you ICMC people place all older papers freely available to a webpage? I could help by scanning the papers only if somebody would borrow me the proceedings and clear the copyrights. I remember a company is selling the PDF vesions. Anyone here has them and could borrow/share them privately for my personal free software development use? If more people could join the efforts, we could turn all interesting algorithms in to free software. Regards, Juhana
