Audio was still pre-ADAT, so we're > talking 24-track tape machines... Just to pick a nit: Audio predates MIDI by about 30 years. Being out of reach I'll agree with, for sure!, but there were tube D/A converters being built in the late 50's at MIT (meaning the resistor ladder type guts, not any "audiophile" type of thing). Tom Stockham and the Soundstream were pre-MIDI, there were various things going on in Europe, and the Synclavier was doing sampling and resynthesis (not sampling playback as we know it) before MIDI. MIDI was '84-ish, and coincides roughly with the release of the Ensoniq Mirage -- the first sampler for under $10,000, but there were a lot of expensive computer systems (standalone or general purpose) that knew something about audio.

Re: [linux-audio-user] Spooky sounds from Saturn

by davidrclark＠earthlink.net

Hi all, Although I'm skeptical that any "audio" from Saturn, especially sampled at 5 kHz is meaningful, it certainly is fun to listen to. It's a good PR thing for NASA to do, I guess... My inner child enjoyed it immensely. Anyway, I took the file and processed it with some of the audio tools that I wrote myself (the true power of GNU/Linux as applied to audio): 1) Upsampled to 44,100 samples/sec using FFT resampler (Sampster, in case anyone cares). 2) Applied stereo convolution reverb (Verbster) with IR's that I calculated for a large room (Boxster). 3) For more fun: Applied a phasor tool I wrote (Phazster) so the sound moves around a little. 4) oggenc http://home.earthlink.net/~davidrclark/linux_audio_users/Saturn.ogg This was about a ten-minute exercise, so isn't optimized in any way. One of the benefits of listening to binaural images with headphones (which is what this case was aimed at) is that you can hear more in a sense. We aren't well-designed to listen to mono, and it's annoying to listen to when trying to analyze a sound. Hope you all have fun listening to it. I'm now out of web space, so I cannot add a techno groove and put up another version. (What a shame, huh?) Regards to all, Dave.

[linux-audio-user] Wanted. 1 pattern of breakbeat in .it or .xm

by nigel henry

Hi to James Stone and James Shuttleworth. Someone (cough) mentioned choons the other day and got me back on the decks. I've got Cheesetracker and Soundtracker and have been having a go at trance and techno stuff, but would really like to do some 90's style breakbeat (155+BPM). I just can't figure out how to set up the breakbeat patterns. If either of you have the time to send me a single pattern to give me a start I'd be very gratefull. Nigel.

[linux-audio-user] A few questions, some suggestions

by BJaY

Hi, I've posted this to CCRMA and LAU, hope this is OK. s/w FC3, 2.6.11-0.3.rdt.rhfc3 kernal, Ensoniq AudioPCI, acpi=off pci=noacpi no-hlt. 1) I recently upgraded from a Celeron 633 to a PIII 866 and now I can't get 48K to work properly. I set qjackctl 48000 but when I start it it reports 47010, Ardour reports 4.7K and QSynth/Fluidsynth is out of tune by about a tone. The clock also seems to be gaining time. This has happened to be before on my laptop (no upgrade, stuff was just out of tune). Suspect ACPI, any thoughts ? 2) Ardour segfaults when I try to resize (time stretch) a bit of audio (latest CCRMA reository) 3) I use the big free NS drum font and now and again, a sample sounds like it's coming from 'both' speakers rather than between them when using fluidsynth, I also happens with other fonts and non-percussive instruments, sonds like a phase shift of some sort, happends on both my machines, anyone else noticed this ? 4) I did some christmas carol arangements for guitar http://www.geocities.com/brooslea/, my first tinkerings with Lillypond, does this qualify for Made With Linux ? Has anyone got a server I can stick them on cos nobody can see them where they are. Also, any feedback on the lilyponding from lilypond guru's (in particular the placement of some of the rests) and the arrangements from guitar guru's gratefully recieved. 5) Anybody got latency figures for usb soundcards ? 6) Getting archives for ardour mailing lists - sourceforge generally. Where do I go to download a tarball of the mail archives on sourceforge ? 7) CCRMA low latency kernal : When it says experimental kernal 'may not work with your hardware' does this mean 'sound card' or are there many other issues ? 8) Issues with anacron and initial experience for music users shifting from Windows to linux : I've not seen alot of discussion about disabling various services (particualryly anacron) in install guides (CCRMA), any chance of adding this with a list of services to disable on the CCRMA install pages ? 9) Would it be a good idea to mention early on on the ccrma site that problems with sound cards should be directed at the alsa development team ? I posted some stuff to the linux-audio-dev mailing list about the trident sound driver (before I got my barings) and it took months to make its way to the alsa team. 10) Any chance of the most up-to-date version of alsa in the core repository (The one that fixes my problem (sis sound chip)) ? As I understand it, if you want to recompile alsa, you have to recompile ther kernal (somthing I have not yet had the guts to do) and I understand it can take all night. 11) Any chance you could add the business of alsa not starting properly on FC3 to CCRMA install documentation. Alot of pelple aquire their FC distributions from the back of a book or download it and then take a long time to become aware of the updates (that seem to fix the problem). This one took me ages. Thanks for all your help - IT WORKS ! Cheers, Bruce.

[linux-audio-user] Jamin Controller Plugin

by Spencer Russell

I've heard and seen this Jamin controller plugin to automate scene switching from within Ardour, but I haven't been able to find it. Does anyone know where it's available? thanks, spencer

[linux-audio-user] Re: Mastered in Ardour and JAMin

by Kjetil Svalastog Matheussen <k.s.matheussen＠notam02.no>

Bob: > > Hi All > Take a listen! > > Ardour and JAmin really doing their thing! > > http://www.hearmymusic.co.uk > Great sound! Except one thing though. The bass is far far too loud! The bassist was the one mixing this tune right? :-) You could also put some more compression on the bass as well I think, its quite bumpy. (Might sound like there are some frequencies in the range 200-400 that is too loud...) Nice drum-sound by the way. Sounds real, didn't hear that it was a drum-machine before I read it on the web-page.

Re: [linux-audio-user] Making Envy24control settings stick?

by Mike Jewell

Thanks Jan and Kevin. Sorry it took me so long to reply to this. I've been doing other stuff... 8^( I tried it and it works perfectly. I have several small scripts to start envy24control with different numbers of guzintas/guzoutas so I just added the alsactl restore command before the envy24control command in each one and it comes up ready to rock n roll! That'll save me hours in the long run. Thanks again. (Sure would be nice if the man page for envy24control mentioned that file and command.)
