[linux-audio-user] [OT] - GMail invitations

by Mark Knecht

Hi, First come - first served. Once again Google has given me 10 more GMail invitations for new accounts. This is gettings sort of standard, but if there are still folks out there that don't have a GMail account and would like one then send me a message OFF LIST. Please send the email address you want the invitation sent in in the BODY of the email you send me and I'll do the work on this end in short time. Sorry for the OT post but this stuff might as well go to LAU folks first if they want it. With best regards, Mark

[linux-audio-user] [ANNOUNCE] Xsynth-DSSI 0.9.0

by Sean Bolton

Announcing the latest release of Xsynth-DSSI, version 0.9.0. New features since the last general release include: * Anti-aliased, hard-sync-capable, minBLEP-based oscillators, including a new variable-slope triangle mode. (LADSPA versions of these oscillators are in the works.) * Velocity sensitive envelopes. * An additional filter mode: Fons Adriaensen's MVCLPF-3. * Much improved (but still plain-looking ;-) GUI, now using GTK+ 2.x. * Polyphonic glide, tuning, and pitch bend range controls. * Updated patch set, and better documentation.

[linux-audio-user] Problems with Ardour

by Pasi Karppinen

Hi! I wonder if anyone else has had any problems with recent versions of Ardour? I'm getting '[ERROR]: state could not be saved to /projects/ardour/testing/testing.ardour' -errors on Ardour's log. System specs: Intel Pentium 4 Prescott 3.2GHz Asus P4P800-E motherboard 512MB DDR400 RAM 160GB SATA disk OS: Fedora Core 3 - default 'workstation' installation Kernel version: Default FC3 kernel 2.6.9-1.724 Planet CCRMA SMP kernel 2.6.10-2.1.11 (I get the same error with both of these kernels, with or without hyperthreading) Ardour versions tested: Planet CCRMA precompiled binary version Self compiled 0.9beta23 Problem description: It seems like I can create one new track and record to it, but when I add another track, I get that error. Could this be a filesystem related problem? FC3 has logical volume manager installed by default. This is what I get to std.err: Loading session /projects/ardour/testing using snapshot testing error : xmlEncodeEntitiesReentrant : input not UTF-8 output conversion failed due to conv error Bytes: 0xB7 0x31 0x22 0x20 I/O error : encoder error

[linux-audio-user] announce-list policy

by Kai Vehmanen

Hello everybody, when linux-audio-announce was created, it was agreed that announcements should be crossposted to all three lists. The reasoning was that this way people wouldn't have to subcsribe to LAA if they were already on LAD+LAU. Now when you look at LAA archives, some people post only to LAA, some (like me) to all three lists, and some to either LAA+LAD or LAA+LAU. My suggestion is that we drop this policy altogether: announcements should be sent to LAA and optionally to LAD and/or LAU. At least I've always had the nasty feeling that I'm spamming LAD+LAU with my Ecasound release announcements. Of course, when announcing conferences, major new versions (JACK-1.0.0 maybe? :)), etc, I see no harm in cross-posting to all the three lists. So in other words, if you really want to see _all_ the announcements, you should subcsribe to LAA. Any comments? If no objections, at least I will from now on send non-major release announcements only to LAA. -- http://www.eca.cx Audio software for Linux!

[linux-audio-user] midi through gameport of emu10k1 based card

by Esben Stien

I'm trying to get my midi keyboard working through the gameport of my emu10k1 based card (Creative SoundBlaster Live). I'm using linux-2.6.10 and alsa-lib-1.0.4. I'm testing with a known to work on usb, a behringer bcf2000 midi controller. Might it be that Creative requires a non-standard cable?. This is what I get: #amidi -l Device Name hw:0,0 EMU10K1 MPU-401 (UART) hw:0,1 Emu10k1 Synth MIDI (16 subdevices) hw:0,2 Emu10k1 Synth MIDI (16 subdevices) #amidi -d -p hw:0,0 0 bytes read #lsmod snd_emu10k1_synth 6784 0 snd_emux_synth 36032 1 snd_emu10k1_synth snd_seq_virmidi 5888 1 snd_emux_synth snd_seq_midi_emul 7072 1 snd_emux_synth snd_seq_midi 6496 0 snd_mpu401_uart 6112 0 audio 46112 0 snd_usb_audio 62880 0 snd_usb_lib 11168 1 snd_usb_audio emu10k1_gp 2592 0 gameport 3296 1 emu10k1_gp snd_emu10k1 93796 1 snd_emu10k1_synth snd_rawmidi 20352 5 snd_seq_virmidi,snd_seq_midi,snd_mpu401_uart,snd_usb_lib,snd_emu10k1 snd_ac97_codec 74336 1 snd_emu10k1 snd_util_mem 3200 2 snd_emux_synth,snd_emu10k1 snd_hwdep 7236 2 snd_emux_synth,snd_emu10k1 Anyone knows what else to test?. -- Esben Stien is b0ef(a)esben-stien.name http://www.esben-stien.name irc://irc.esben-stien.name/%23contact [sip|iax]:b0ef@esben-stien.name

[linux-audio-user] Re: setting loop-points

by Bill Schottstaedt

> At one time you had created a loop-point editing module for Snd but > IIRC it was never actually functional. Any chance that it might be > revived for implementation ? It's in marks-menu.scm (create-loop-dialog), but, as you say, not fully functional. I think it's based on Richard Kent's work (am I remembering that right -- DAP?) -- I copied it in a monkey-see-monkey-do sort of mode, but I've never used loop points, so I don't know what is going on -- someone who cares about these things needs to tell me what they want -- or even better, write the rest of the callbacks themselves.

[linux-audio-user] multimux and generating 5.1 AC3

by Florin Andrei

I'm looking at this tutorial: http://mightylegends.zapto.org/dvd/dvdauthor_howto_surround.html When muxing all the 5.1 channels together, the author recommends to add a 15ms delay for the rear channels. Is that correct? I thought it's the amplifier's job to do that. My home theater system adds a 10...12...15ms delay anyway (adjustable). I believe, if i add another 15ms in the AC3 file, it will be too much. What do you think? Also, the tutorial is based on the multimux utility: http://panteltje.com/panteltje/dvd/ Is there any other command-line tool that performs the same functions like multimux, or is it pretty much unique? -- Florin Andrei http://florin.myip.org/

[linux-audio-user] 2.6.10

by Lee Revell

I tried JACK today with vanilla 2.6.10 and had excellent reaults - it works with 32 and 64 frames, which previously required Ingo's patches. Many of the latency fixes have been going upstream, and it looks like we are finally showing some results. I think we may finally have a kernel that's usable out of the box for low latency audio. Can someone else try to verify these results? Lee

[linux-audio-user] converting large number of ogg's to mp3's

by rob

Hi. I need to convert a large no of ogg's to mp3. I know that I can convert them one at a time with sox but this is going to be fairly tedious for >1000 files. Does anyone know of graphical way of doing this or failing that how I get sox to convert an entire directory tree of files. (nb I don't need the id3 stuff) Thanks for your help. -- rob
