I remember answering that question here many years ago and had found two or three working ones. Marc.info still exists and is searchable, but the closest to this list is Linux Audio Dev at: https://marc.info/?l=linux-audio-dev&r=1&w=2 (unless I missed it here: https://marc.info/) So^W Anyone know the location of a searchable archive of this list? My search results generally seem to lack anything but links to where I can buy one... -- Thanks again, John.

Audio Drop-outs and JACK Errors - Seeking Assistance

by David Klann

Hi Linux Audio Enthusiasts! I'm a fairly long-time JACK user (more than a decade, anyway), but I must admit I don't really know it that well. I'm seeking guidance with the following situation. I am hearing audio "drop-outs" (a second or two of silence) that seem to coincide with this error in jackd output: JackAudioAdapterInterface::PushAndPull ringbuffer failure... reset The audio hardware is a Digigram LX-DANTE connected to the JACK graph via ALSA device hw0,0. jackd --version is jackdmp version 1.9.18 tmpdir /dev/shm protocol 8 Also, jackd output fairly regularly (several times per minute) shows messages like: JackRingBuffer::Write : consumer too slow, skip frames = 1024 and JackLibSampleRateResampler::ReadResample error written_frames = 1020 Output available = 1022 Where the number after the "=" in the "written_frames" line is between 1020 and 1023, and the number in "Output available" is always two greater than the previous. I start jackd (as Linux user 'root') with the command: /usr/bin/jackd --realtime --name default -d dummy -r 48000 And then add the Digigram client with the command: /usr/bin/jack_load -i "-d alsa -d hw:0,0 -i 64 -o 64 -r 48000 -p 1024 -n 2" Digigram audioadapter Thanks for any thoughts about these drop-outs! And please let me know if there are other troubleshooting tools available. Best, ~David Klann

Re: [LAU] Fwd: The audacity of Audacity: Telemetry / Google Analytics added

by bil＠ccrma.Stanford.EDU

Thanks for mentioning Snd. It looks a bit old-fashioned now, since I removed the gtk support -- only motif, or command line. It's almost 24 years old! I think it has a different emphasis than Audacity, so it might not be a drop-in replacement.

It appears that the first time the application is run there are some resources not yet setup, but when they are created the application does not load them right away. Run once, shut down, run again and all the translated text labels and menus are available. It does look like it could be interesting. -- Chris Caudle

San Francisco contacts ?

by Dave Phillips

Greetings ! A student of mine is traveling and will be in the San Francisco area soon (within the next couple weeks). She'd like to see some musical sites, so of course I've recommended she check out CCRMA. Are there any other notable places or events - music stores, art museums, concerts - that she could check out while she's there ? Any and all recommendations appreciated ! She's a beginner in electronic music production, working mainly with a Grimes-like setup including Ableton Live, a nice Arturia controller, a few good VST synth plugins, and - best of all - an open mind and a receptive ear. Thanks in advance ! dp

Installer Script for cm-incudine on Arch Linux-based Distros

by Brandon Hale

Hello all, Have you ever wanted to use cm-incudine, but felt like it was too hard or too much work to install on your Arch Linux-based distro? Now you can install it with https://github.com/brandflake11/install-cm-incudine <https://github.com/brandflake11/install-cm-incudine>. This script will take you from zero to hero, installing emacs, slime, quicklisp, and all of the dependencies needed for cm-incudine. Hopefully this helps you install cm-incudine if you've ever been interested, but couldn't figure out all of the smaller bits. Feedback is welcome! Thank you very much for your time, Brandon Hale

Open Sound Control: Is it still a thing?

by worik

Vaguely Linux Audio related Is Open Sound Control still a thing? Was it ever? I am shopping for a mixer, I am a bit worried that the digital controls are a bit too propitiatory. I do not want to get orphaned by a firm going out of business and letting its iPad App rot. OSC looks like a solution, but it does not seem to be implemented by many vendors I am hoping that eventually the mixer will be controllable by the software I am building around a Raspberry Pi Worik -- If not me then who? If not now then when? If not here then where? So, here I stand, I can do no other root(a)worik.org 021-1680650, (03) 4821804 Aotearoa (New Zealand)

Four channels playback?

by Rodolfo Medina

Hi everyone from a new one to this list. It is a sort of experiment. Suppose you have a multi channel audio file, i.e. composed by, say, three, or four different channels. Is it possibile (I guess it is), and how?, to send each of the four channels into a different loudspeaker and so listen to the song...? Do you think, e.g., the Behringer UMC404HD audio interface will allow to do that? Thanks in advance for any help, Rodolfo
