Hi list, I'm running a new Arch Linux system now and have come up against the Pulse/JACK dilemma. The Arch Wiki suggests several alternatives, the old, the new and the new new way. The latter being only suitable for JACKD with DBUS support, which I don't have. As far as I'm aware, the DBUS version only works with X running, which I don't want, all the time. Unfortunately, the Arch Wiki isn't accessible right now, so I can't post the proper link. But the described metho uses shell scripts setting PulseAudio sink and source modules to JACK and default sources and sinks to jack_in and jack_out respectively. I start JACK through a self-written systemd service. Should I start PulseAudio by default as well? Can such a shell script with Pulse settings be executed at startup as well? I'm sorry to raise the topic again, but I'm so very new to that snake pit. I'd be grateful for any tips, reading material for that situation. Best wishes, Jeanette -------- When you need someone, you just turn around and I will be there <3

Drifting

by Will Godfrey

Sometimes you get so bogged down in problems that you tend to forget what it's all about. Well, after a series of seemingly intractable coding issues on Sunday, I decided to take a break and instead pootle about on my DAW. Picking up a barely started project I'd laid aside, for once things went surprisingly smoothly, and this was the result. I hope you enjoy it. https://soundcloud.com/soft-sounds/drifting The icing on the cake? It turned out to be a perfect match for this months KVR competition theme :) -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

AVL-Drumkits 1.1 Released!

by info＠bandshed.net

HI, I have just released an update of the AVL-Drumkits (now at 1.1). For those who are unfamiliar these are free sample libraries of 2 complete Drumkits and hand percussion in Hydrogen, SFZ and Soundfont2 formats. These kits are intended to bring an authentic acoustic, organic drum sound to your MIDI DAW arrangements and preserve real-world characteristics such as tom ringing and overtones unlike many General MIDI kits that sound sterile. AVL-Drumkits feature 5 sample layers per kit piece, have a very light memory footprint and are suitable for systems old and new. The shell samples provide both center and edge hits to emulate right and left hands and the cymbals are quite realistic without truncated samples. Additional resources are available such as a PDF Keymap and Midnam files to use with MIDI tracks in Ardour and Mixbus. Changelog: * - Now licensed CC-BY-SA [1] with a slightly modified license (Thanks to Nils Gey) * - NEWLY ADDED SOUNDFONT2 VERSIONS! (tested with the new 'a-Fluid Synth' plugin in Ardour 5.4) * - Cleaned up formatting of SFZ text files with better key number ordering (didn't affect performance, just my OCD) * - New Kick drum samples for both kits with fuller sounding closed resonant heads. Downloads, more detailed information and Audio and Video demos of the Kits can all be found at the AVL-Drumkits webpage: http://www.bandshed.net/avldrumkits/ Enjoy!

Jack and CM-Headphone Codec audio recurring gets corrupted

by Peter Allen

Hi all, I have a super cheap C-Media USB Headphone Set based sound card (it's all over ebay as a guitar-link). It isn't awful quality wise (I was expecting worse, although it did require a bit of soldering to get it working at all..), so I'm interested in getting it working well, however when I run duplex jackd I have a problem: With -p64 -n3, approx every minute the recorded audio gets corrupted for about 15 seconds, then it sorts itself out for another minute. I've uploaded an example of the problem with a sine wave input here: https://dl.dropboxusercontent.com/u/51719910/CMJackIssue.ogg https://dl.dropboxusercontent.com/u/51719910/CMJackIssue.wav If I change to -p128 -n3 it happens approx every 2 minutes, and it doesn't happen in input only mode from what I can tell. Has anyone got any thoughts? Thank you Pete Linux version 4.4.0-38-generic (buildd@lgw01-17) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.2) ) #57-Ubuntu SMP Tue Sep 6 15:41:41 UTC 2016 /usr/bin/jackd -dalsa -dhw:Set,0 -r48000 -p64 -n3 -s -C -i1 jackd -v jackdmp 1.9.11 cat /proc/asound/cards 0 [MID ]: HDA-Intel - HDA Intel MID HDA Intel MID at 0xd7820000 irq 31 1 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0xd1000000 irq 16 2 [Set ]: USB-Audio - C-Media USB Headphone Set C-Media USB Headphone Set at usb-0000:00:1d.0-1.5, full speed cat /proc/asound/card2/usbbus 002/012 cat /proc/asound/card2/usbid 08bb:2902

file organization ?

by Dave Phillips

Greetings, Recently I embarrassed myself by making and posting a piece that used material created by another composer (fortunately a friendly one). When notified of the issue I immediately withdrew the piece from circulation and apparently all's well that ends well. However, on reflection I find that I am a very disorganized person who has amassed a huge number of soundfiles over the years. I've tried to keep them organized, but I could really use a file manager dedicated to managing soundfiles. I'd like to click on a file and see the kind of information displayed by sfinfo and similar utilities. I'd also like to see the file's metadata in the same display. Does such a file manager exist ? How do you manage very large collections of soundfiles ? Best, dp

Updates

by Fons Adriaensen

Updates now available at the usual place: <http://kokkinizita.linuxaudio.org/linuxaudio/downloads/index.html> *** Regarding zita-ajbridge: If you experienced unexplained *** and repeating 'Excessive timing errors', this release will *** fix those (unless there really is a problem). * zita-resampler-1.6.0 - Added VResampler::set_phase * zita-dpl1-0.1.0 - Maintenance and small bugfixes. * zita-ajbridge-0.7.0 - Fixed bug in DDL computing timing of Alsa periods. Thanks to Tomasz Kasprzak for the bug report and fix. - Fixed bug in automatic selection of resampler quality. Previous release always used a short filter unless the lenght was explicitly set. * zita-njbridge-0.4.1 - Fixed bug in DDL computing timing of network packets. - The data format 'on the wire' has changed. It should be backwards compatible, but to be sure please use this release on both ends. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)

Life of a zebra, a tune made with Lin...^w DOS !

by Benoît Rouits

Hello, As i recovered an old hard-disk-drive from the 90's (30MB HDD form an i386 DX40) i could reap one of the oldest MIDI files i 'recorded' under DOS (or win31 ?) with an MPU-401 while i was not twenty years old yet. I don't remember which software i used at this time... The midi was not quantisized and needed some polish, so i rewrote it on Musescore tonight after listening carefully to the original. Its name was 'essai3 ' (third try). But i found i could rename it as 'Life of a zebra', just for fun: http://brouits.free.fr/music/various/life_of_a_zebra.ogg I hope you will enjoy this short tune as i had pleasure to rediscover it ;-) Cheers, -- Benoît

Building avplay

by jonetsu

Hello, How is the avplay binary, part of libav, produced at compilation time ? avconv and avprobe are produced and installed, but there's no sign of avplay. configure only have a --disable-avplay option. The make log shows no sign of avplay but shows the compiling of avprobe and avconv. libav is configured simply with: ./configure --enable-shared This is libav-11.8. What is the incantation to have avplay built ? Cheers.
