Nothing new really, but it's on SoS so I guess it's worth a read ;) http://www.sospubs.co.uk/sos/apr03/articles/cuttingedge0403.asp -- http://www.eca.cx Audio software for Linux!

[linux-audio-dev] ecasound 2.2.2 released

by Kai Vehmanen

1. A short summary of changes A new native Python implementation of the ECI API has been added to the package. Ecasound.el (ecasound-emacs) has been updated to version 0.8.2. Oggs and mp3s can be now streamed directly from network. Author information is now visible in the LADSPA plugin descriptions. Changes in ALSA-0.9 support improve usability of ecasound with the new ALSA dmix PCM plugin. There have been many important bugfixes including correct handling of short parameter fades, broken chainsetup level looping, problems with creating temporary files and minor build system issues. --- 2. What is ecasound? Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licensed under the LGPL. --- 3. Changes since last release Full list of changes is available at <http://www.wakkanet.fi/~kaiv/ecasound/history.html>. --- 4. Interface and configuration file changes None. --- 5. Contributors Patches Janne Halttunen (the new Python ECI implementation) Mario Lang (ecasound.el 0.8.2) Junichi Uekawa (pyecasound.so build) Kai Vehmanen (various) Bug Hunting (items closed) William Goldsmith (2) Michael Hellwig (1) Janno Liivak (1) Raoul Megelas (1) Feature requests (items implemented) Oliver Thuns (1) --- 6.

Well, that sounds perfect to me; David and Brad have experience of Linux coding, and you have the test and packaging experience. I really want to get into Linux coding, and am quite happy to do the admin and docs as req'd. I think we could both learn some new things :) As you said, David, asm isn't really used, as the goal is portability. It might come in handy once we've got a driver working and we want to improve its latency on a specific platform. (I'm thinking Intel and ARM from my side.) Wrt pages of code per model, I agree with you that hopefully we can get round that, perhaps by having a glue layer to different cards. I don't know, it's been ages since I looked at the code. Have you seen the Echo code, Brad? I'd suggest we make sure we all have a copy, even if we can't post it to a central site, so that we are starting from the same point. We need to classify all the operations that we must provide (the API) and the operations we can build on from the cards. I'd imagine there's a core set.. What do you think? > Odd things like the top jack of a two-jack stack becoming inoperative after > plugging in the bottom plug (in balanced mode). Sounds like you've got a short in there somewhere.

[linux-audio-dev] recording, sample rate problem

by Turos Laszlo

Hi I'm trying to write a soundrecorder application under linux. I have Redhat 7.2 with kernel 2.4. Playing sound on my soundcard works fine,but I'm having problems recording. I was using GNOME Sound recorder 1.2.3 to record sound but it seems that it can only record sound at a 48000 Hz sampling rate,but playing back the recorded sound it is a noise. I wrote a little program myself and I reached the same conclusion that I can not set other sampling rate than 48000. My soundcard under Windows records good sound with other sampling rates. I have my soundcard on my VIA motherboard. In my harware Browser looks like this: Manufacturer: VIA Technologies Driver: via82cxxx_audio Can anybody give me a hint? Best regards Laci

[linux-audio-dev] midi 'resolution'

by Lukas Degener

Hi list, maybe someone can explain this to me (me==stupid :-) ) In a system/application, that recieves external midi data of any kind, is there anything one can assume about _when_ some midi data is recieved? i mean, with audio data, you have the buffer size of the dac/adc, which (together with sampling rate) enforces some kind of "global clock" impulse/trigger in your system. Is there anything similar with midi data? Still waiting for enlightenment, Lukas ps: oh and btw, i would like to say another BIG THANK YOU to Frank and Matthias and all the others involved in making the lad conference possible. i had a realy great time there. Hope we can have something like this again in not to far future.
