Re: [linux-audio-dev] 3D fft analysis program

by Downer

Baudline (http://www.baudline.com) is a fantastic viewer that does fft cascade. I've used it for a couple of years, and it is great for figuring out how different sounds "work", and it has an oscilloscope-type display as well. Cheers, Jason Downer

[linux-audio-dev] Drum synth

by Dmitry Baikov

Hello. I finally started making my pet music project and realized I need a drum synth to make some cool sounds. psindustrializer is good but also need some tr-909-style sounds. I remeber from my old windoze days I used a nice piece of software called Stomper. Does anybody know any software for linux with comparable capabilities? Or we need to write one? Stomper does not work under wine :( Thanks.

[linux-audio-dev] Re: Drum synth

by Juhana Sadeharju

Hello. I had a couple of articles on drum synths. Check ftp://ftp.funet.fi/pub/sci/audio/devel/lad/drumsynth/ I built the circuit in a00*.jpg at the time when this article was fresh. The article b00*jpg mentions an earlier article. I will check that out at library. Hmm.. I coded a drum synth for Commodore VIC-20 at the time. VIC provided an audio chip with three oscillators, noise, and a common volume if I remember correctly. What I did was to modulate osc pitch and volume parameters with a fast and accurate (compared to Basic) assembly code. The drum sounds were assigned to the keys. This was about 1984, inspired by Yamaha's digital RX drum synths, not by analog drums.

Re: [linux-audio-dev] impulse convolution LADSPA plugin

by Stefan Turner

Hi Steve, thanks for the reply. I will definitely look into using DSSI, looks like it could be good once as supported as LADSPA is (I'd never even heard of it before your post, although that's probably just me). Is it intended as an eventual LADSPA replacement? I never really saw the need to divide plugins into 'instruments' and 'effects', and it seems like DSSI can do both.

[linux-audio-dev] Firewire Audio Card Support

by Olaf Christ

Hi, as the owner of a firewire audio card (Motu 828mkII) I was disappointed when trying to use it under linux. Asking Motu to provide tech docs and/or linux drivers is useless: "We will possibly release linux drivers in the future, but we never release any kind of technical documentation." Is there any effort to join forces for putting pressure on the manufacturers yet? I am willing to create an address list ordered by audio card manufacturer/model to make the manufacturers realize there is a need for linux support. Any comments?

[linux-audio-dev] adm: list archives at eca.cx going away

by Kai Vehmanen

Hello, this is not an urgent issue, but I'd like to warn in advance that the laa/lad/lau list archiving at www.eca.cx/la[adu] will stop some time next year. I'm not sure of the exact date, but sooner or later anyway. Note that I'm not going to take the existing archives offline, so all links pointing to mails at eca.cx will still work. Fortunately we nowadays have many other archives of the lists. We just now need to pick a new official archive and update the links at: http://www.linuxdj.com/audio/lad/archive.php3 I propose that we use the archives at columbia.edu: http://www.music.columbia.edu/pipermail/linux-audio-dev/ ... and so on. Very good archives can also be found at gmane.org: http://gmane.org/info.php?group=gmane.linux.audio.devel ... and so on. -- http://www.eca.cx Audio software for Linux!

[linux-audio-dev] RME is no more

by Marek Peteraj

Hi all, sorry for crossposting, just wanted to let everybody know: The official statement is that there will be no support for ALSA (Linux) FireWire drivers from RME. In other words there will be no such drivers, as it is impossible to write them without tons of hardware and software documentation from RME. And we won't share these information with anyone. Regards Matthias Carstens RME No further explanations. The moral of this story is: Never buy a product that isn't already supported in ALSA, such as i did. :( There's no guarantee even if pretty much every other card from the same manufacturer *is* already supported. Me and Benno talked to Matthias personally during Musikmesse, he was friendly and seemed to be open with regards to future cooperation with oss developers. Seems like things have changed dramatically since then. Marek

[linux-audio-dev] ladspa 2 idea

by Taybin Rutkin

I don't know if this is completely dead or just a little dead but I had an idea today. It'd be kinda neat if there was a mechanism for grouping related control ports together in the UI. Taybin

Sure but the result is the _same_ with respect to what they deliver(state of art technology), which has the same value for me.

Did someone from russia or taiwan knock-off a copy? Does RME suffer from us having alsa drivers? Are russian engineers or taiwanese engineers(envy24 btw AFAIK) not smart enough to come up with their own superb design? Is it too hard for smart people to reverse-engineer?

My intention wasn't to post that on /. at least not now. I was thinking out loud. Of course, in case we did a market survey it would definitely be needed. > RME has provided > "Pro" grade audio hardware when Linux Audio needed it > in order to become a legitimate alternative to > proprietary solutions. Not really. It was Paul, Thomas, and one other guy(don't remember the name) who did. Remember it was almost no investment from RME's side. They got a lot of units sold in return and built a very good reputation based on that fact and this went beyond the linux audio world i believe. > I hope you consider how much > work has gone into Linux Audio But that's what i'm talking about. So much effort, oustanding technologies(although i know the authors won't admit ;) and they(hw manufacturers) don't care! > and how difficult it is > to develop that type of business relationship. There is no relationship. The only real manufacturer from the POV of linux audio is audioscience(.com), which unfortunately does only broadcast hw. They do ALSA drivers, provide support and invest their time and money in doing so. They deserve highest respect for that considering the current situation. That's how it should be. And this is what we should fight for. > > Whether you are in the right or wrong, is it > inconcievable for you to act for the interests of many > people by selling the unit and getting something else? Not sure i understand. I'm about to sell my fireface copy as i declared previously. Of course if there's any way i could help out other people here in keeping the unit, i'm prepared to do so. Marek
