[linux-audio-user] DSP2000 C-PORT and MIDI input

by Emiliano Grilli

Hello, I have recently bought the ice1712-based DSP2000 C-PORT from Hoontech and I'm really satisfied with it. I only have a little problem: MIDI! The card has 1 MIDI in and 2 MIDI out, and the 2 outs are working fine. However, I can't get anything from MIDI in :-( Anyone has that card and can confirm this problem or I have to check my hardware? Maybe ALSA get confused? With aconnect I see 2 devices (0 and 32) both as inputs and as outputs... I've tried on the staudio.com forum and they suggest to test the card under windows, but (ehm..) I don't have it... Any suggestions? TIA -- .-----------------------. | Emiliano Grilli | | emillo(a)libero.it | | Linux user #209089 | | http://www.emillo.net | '-----------------------'

[linux-audio-user] ams, jackd & X as root? on debian

by Eric Dantan Rzewnicki

hello, I have jack installed and working now. So, now I'm trying to get AlsaModularSynth compiled and running. Has anyone else accomplished this in debian stable (woody)? I installed libqt3-mt (along w/everything it depended upon), fftw-dev, fftw2, sfftw-dev, sfftw2 and ladspa-sdk to get ladspa.h. I've tried to edit the top of make_ams to agree with the location of the qt3 libs, bin and include directories on my system as best as I could figure ... but I'm not sure I got it right: QT_LIB_DIR=/usr/lib/qt3/plugins/styles QT_BIN_DIR=/usr/share/qt/bin QT_INCLUDE_DIR=/usr/include/qt it seems to compile OK when I do: make -f make_ams though there are a lot of warnings about comparing signed to unsigned and other warnings that flew by. Are these benign? Anyway. I end up with an executable ams. When I run ./ams I get this: ./ams: error while loading shared libraries: libjack.so.0: cannot open shared object file: No such file or directory I have that in /usr/local/lib/libjack.so.0 so creating this link appears to help: box1:/usr/lib# ln -s /usr/local/lib/libjack.so.0 libjack.so.0 Is that the correct sollution? but, now: box1:/home/eric/audio_code/ams-1.5.5# ./ams ams: cannot connect to X server I assume this is because X is running as me (eric) and not as root. I'll try getting out of X and starting it as root as soon as I finish writing this message. But, is there a way to let root connect to the X server that's running as eric? I was sort of ok (well, not really, but I'm giving it a try) with the idea of running jackd and its clients as root ... but, running X as root, too? that makes me more nervous, somehow... maybe I shouldn't be nervous about that ... I'm not sure. anyway. i'll give it a shot with a root X session. I'm thinking that maybe I should patch and recompile the kernel and recompile jack to enable capabilities so I don't have to run as root. Do those of you running jackd as root also run your X session as root? Thanks for listening, Eric Rz. PS If all of this has been covered before and my questions are annoying you, feel free to send me to the archives. I try to follow jackit-devel, but most of it seemed to go over my head before I actually started to try it. So, re-reading the past couple months would probably do me some good now that I have the real thing in front of me. -edrz

[linux-audio-user] stretching sound

by Julien Claassen

Hi all! I've been trying to stretch a soundfile. It is a piano track with mostly two voices only. I did it with an fft plain phase vocoder. Now there are a lot of parameters and I got some undesireable delay. In general the stretched sound was good, but the delay is disturbing. So here's the question, how should I set the following parameters to get the best result? fft-length (as high as possible?), windows per second, window length, windowtype (hamming, triangular, kasier with several coeffecients). Any ideas or practical experience with that? - I'm NOT doing it in realtime, so CPU-time is no problem. I've got time! :-) Thanbks for any help or good ideas!

[linux-audio-user] Recording in 7200,8bit,Mono !

by Udaya Kumar.R

Hi List, I want to record in 7200 frequency, 8bit, mono. Well the specs may seem strange but we have a HardWare which understands voice files only with these specs. I have 2.4.18-3 linux kernel. I have intel 810E chipset, with builtin audio card. lspci returns <lspci> Multimedia audio controller: Intel Corp. 82801AA AC'97 Audio (rev 02) </lspci> I too have Sound Blaster Live. lspci returns <lspci> Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 08) Input device controller: Creative Labs SB Live! MIDI/Game Port </lspci> And we use xwave and soundstudio for recording. And i have intel audio card under alsa. Intel Audio Card: I could record properly in 16 bit, but when i record in 8 bit it gives lot of noise. I dont know from where it comes. Sound Blaster Live: I could record in given specs, but when i play back the bass gets increased. I mean it dosen't seem to be the same voice anymore. Can anybody help me. TIA. bye. uday. -- Reply To : perl -e 'print pack "H*","756b5f6369407961686f6f2e636f6d";' OR to the above 'From' Address

[linux-audio-user] Recommendatio wanted

by Joerg Anders

Hi all! I used to play MIDI with AWE-64 with 24 MB RAM extention. So I could use the SF2 soundfonts. Unfortunately, the AWE-64 requires an EISA slot. Could please enybody recommend a PCI successor of the AWE64 which allows loading of SF2 soundfonts. Please do not recommend Audigy! This is a lie! The Audigy ALSA driver accidentally drops some tones. This is a known bug, but apparently nobody is willing to fix this See. http://www.alsa-project.org/alsa-doc/doc-php/template.php?company=Creative+… Furthermore it ignores reverbation and chorus instructions. Please do not recommend FluidSynth. To avoid misundersandings: Actually FluidSynth is a good software. But it produces wrog envelopes for strings and clarinets. The envelops are like xylophone (or so ...) I alreay mentioned this problem on this list. But without success. -- J.Anders, Chemnitz, GERMANY (ja(a)informatik.tu-chemnitz.de)

[linux-audio-user] Announcing the ultra-mega-alpha release of Specimen

by Peter Bessman

Specimen is a midi controlled sampler, and it's very first public release is available from http://www.gazuga.net/specimen.tar.gz In all honesty, I advise against downloading this in it's current state unless you intend to hack on it or play with it for sheer amusement value only. There are a few TODO items that must be taken care of before this can be considered usable software (as the next release will be). The main reason for this release is because I said I was going to make a release in a couple of weeks 15 days ago. It's very nascent stuff. You have been warned. [pb]
