[linux-audio-dev] Re: [fluid-dev] question - soundfont editing

by Tim Goetze

[David McNab] >Sorry to bother you again, but there's a slight problem with your SF2 >python module. > >If the soundfont file I write out contains one or more drum presets, >'asfxload' spits an error 'loop size is too short: 0' when I try to load >the font into my sblive card. However, fluidsynth loads it in fine. loading the original sf2 gives no error from 'asfxload'? loop size 0 is legal for unlooped samples (which many drum sounds of course are) fwiw. i'm not quite sure if SF2.py handles stereo samples correctly, however this doesn't seem to be related. can you check whether the presets have stereo samples? other than this potential problem, SF2.py shouldn't change a thing about the sf2 data it handles. i'm afraid you'll have to narrow the problem down a bit. tim

[linux-audio-dev] re: [linux-audio-user] A bit of good news -- paper now available for your viewing pleasure and/or comments

by Ivica Ico Bukvic

Ok, so the rough version of the paper (following initial 10-hour revisions that converted my brain into a gray mush) is now available in the PDF format from my website. If you are interested in providing some feedback as to how I can make the paper even better, please let me know asap as I only have another day or so before I need to turn-in the paper. Also please note that the paper will be available in the ICMC proceedings as a short version that lacks chapters 7 and 9 due to space constraints. The full paper will be available online-only. The url to the PDF is as follows: http://meowing.ccm.uc.edu/~ico/temp_online.pdf Any comments and/or suggestions are welcome and appreciated (although I honestly cannot guarantee that all of them will make it into final revision due to aforementioned deadline). Time to hit the sack... Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico/

[linux-audio-dev] q - asfxload/emu10k1/sblive problems

by David McNab

Hi, I'm using a Soundblaster Live! card (emu10k1 driver) under ALSA. The 'asfxload' util works fine for loading a single soundfont. But when trying to load different soundfonts with the '-b1' option, for instance: asfxload -b1 dance.sf2 I get: asfxload: invalid option -- b asfxload: invalid option -- 1 This conflicts with the manpage for [a]sfxload. Also, when I send Bank Select messages from my MIDI keyboard, these get ignored (although Bank Select LSB works when I use fluidsynth). Any thoughts on either or both of these issues? -- Cheers David

[linux-audio-dev] Linux Live CD (Audio)

by Oliver

Hi, forgive me if this question has been asked before: Is there something like a Linux Live CD optimized for and containing audio (editing) applications? Something like this http://www.frozentech.com/content/livecd.php where I can simply insert the CD, boot from it, and start working on my songs? -Oliver Mit schönen Grüßen von Yahoo!

[linux-audio-dev] A bit of good news

by Ivica Ico Bukvic

Hi all, Just found out that I will be presenting a paper titled "Linux as a Mature Digital Audio Workstation in Academic Electroacoustic Studios - Is Linux Ready for Prime Time?" at the upcoming ICMC2004 (International Computer Music Conference) this fall. Although I have only 3 more days to do final editing for the camera-ready paper :-(, if you have any ideas or thoughts for additions to the paper I will certainly read through them and try to add them (if they are not already included). I will be also posting a preliminary draft as soon as it exits the realm of "ugly" ;-) Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico/

[linux-audio-dev] LADSPA proposal ...

by Paul Davis

well, it appears that there is little to no response to the proposal from the LADSPA meeting at ZKM. just to be sure that the silence is an accurate reflection of what people think, i want to take a harsh stance on the proposal and see if it generates any response... if we follow through with the proposal, LADSPA will no longer be a header file. it will require the use of a library. the actual struct in the header file will contain the absolute bare minimum information required to actually run a plugin, nothing more. No port names, no hints, no default values. we will try to make the library self-contained, dependency-free, but it will still be more complex than the current model. moreover, there will be 2 versions of LADSPA floating around, thus leading to problems with host/plugin compatibility issues. personally, i think its worth going through this pain. we will end up with a system in which new LADSPA extensions do not require changes to the API, which is a great thing. but it will be painful to get there, and i want to check that people don't mind doing it. --p

by Tim Goetze

[David McNab] >Can someone please recommend a program for Linux which can easily take >presets from one or more existing soundfont files, and compile them into >a new soundfont file? with about 10 lines of python (plus a few to name the presets you're after) you can do such tricks with this little helper here: http://quitte.de/file-formats/SF2.py at the end of the file it shows how to extract one preset into a separate .sf2; modification for many presets/sf2 files should be straightforward. cheers, tim

[linux-audio-dev] Info required: FLAC on W*****S

by Alfons Adriaensen

Hello list, I'm involved in a (friendly) debate on the surround sound list. One the main contributors of this list, Angelo Farina (univ. of Parma, Italy) wants to make available some interesting 4-channel recordings he recently made. The distribution format has to be lossless. I already pointed him to FLAC and the Windows tools available for this format. He tested these and has some objections: - The codec does accept WAV, but not WAV-EX files. - There seems to be no Windoze player that can handle 4 channels FLAC files directly. I'd like to exert some gently pressure towards an open source format, but then I'll need some answers to these problems. So if anyone has some information about this, I'd like to know. All this may be a bit OT, so maybe the best thing is to contact me by email. TNX, -- Fons
