Any success running Jack on a Chromebook that's running Crouton?

by Jeremy Carter

Hi all, I have a Acer C720 Chromebook, and I run Debian Stretch on it using a hybrid OS approach using a technology called Crouton ( https://github.com/dnschneid/crouton ). It runs some kind of audio server proxy called Cras to get the audio from ChromeOS into Debian, and I have been unable to get Jack running with it. I'm wondering if anyone has any hints or success stories about running Jack and/or Ardour in a similar environment. I get a permission denied error (on /dev/sng/seq) when trying to start jack using qjackctl with ALSA midi seq enabled. If I disable MIDI support, I get "control open "hw:0" (No such file or directory)" and "ALSA lib pcm_hw:1701:( snd_pcm_hw_open) Invalid value for card" I would like to do some audio production on the chromebook, or at least get that stuff running to see if the performance for that would be acceptible. Let me know what other information I should provide to try to get this working. Regards, Jeremy Carter

jam22: electronica improv

by jonetsu＠teksavvy.com

This one is a "one synth" type of thing, although with some drums and percussion. It features a theme followed by two solos. A total improvisation done rather quickly although some time was spent mixing it, with several iterations evaluated over 2 weeks. The synth is u-he's Hive. I yet do not make sounds and so I thank people out there who are so creative in creating patches - for me it is still some kind of mysterious art. Cheers ! https://soundcloud.com/nominal6/jam22 Hive instances: Bassline: Transmitting Spheres - ARP Bassline Ana Supporting arp: VSP Liquid Sounds - ARP Green Spurious chords: 'native' Howard Scarr Aerodrome Bass drum: 'native' KS Bassdrum gated Theme: Melodic Enchantement - TI Pulsar 1st solo: Melodic Enchantement - TI Enigma Arts 2nd solo: Melodic Enchantement - TI Travel in a dream Ambient: 'native' ETE Clouded Percussions: Drums: Bluezone Downtempo - Dbox loop 1004 Cymbals: Mode Audio BeatScenics - Greener Grass Sketched out in Bitwig, single tracks exported pre fader into Mixbus 32C for mixing. Mixbus: XT-EG, XT-DC on drums, XT-EG on bass drum. Reverb on various mixbusses: Uhbik-A. Uhbik phaser on cymbals. Master bus: XT-ME, and a Presswerk that despite its preset name of being 'Gentle loving' is working quite a lot. Ambient, bassline and arp tracks were doubled and panned. The copied bassline track was filtered highly to extract only the midrange and then blended in back with the original. Exported "sans norm" Integrated loudness: -17.7 LUFS Loudness range: 1.4 LU Peak: -1.5 dbFS True peak: -1.5 dBTP Twin peaks: no way

[Music] 3 Breaths For Helm - KVR OSC90 entry

by Dave Phillips

Greetings, My whimsical offering to the current One Synth Challenge at KVR : https://soundcloud.com/davephillips69/3-breaths-for-helm-kvr-osc90 Three atmospheric soundings using nothing but Matt Tytel's Helm. Sequenced with Bitwig 1.3.12, audio mixed and rendered in Ardour5. Downloads enabled. Voting hasn't started yet, btw, I just wanted to put the notice out there. I know that Rob van den Berg (aka rgvhdberg) has submitted a piece. Any other Linux Helm users stepping up to the OSC ? There's still time to enter, see http://www.kvraudio.com/forum/viewtopic.php?f=1&t=467516 for the details. Best, dp

robust command line tool to determine duration of sound file using more than the header

by Dan Hitt

I'm looking for a command line tool that can determine the length (duration in seconds) of a sound file using more than just the file header. The situation is that some of the files have incorrect headers. The data is intact, and they play correctly, but if you attempt to determine the length based solely on the header, it will be incorrect. I've tried soxi, mediainfo, and ffprobe (on xubuntu 16.04), and all seem to rely exclusively on the header. soxi is good enough that it warns if there's a discrepancy between what the header says and what is present in the file, in a message to stderr, but the value to stdout (from soxi -D) is the incorrect header value. I suppose i could write code to parse soxi's error message, but would much prefer to have some option to pass to the program that says "use file length instead of header info in the event of a conflict". TIA for any suggestions! dan

new switchless wah plugin

by Hermann Meyer

Hi On request, I made a switchless wah plugin out of the GxWah.lv2 This means, the wah effect gets activated by moving the wah pedal and slips in bypass, when the pedal isn't moved. Attack and Release times could be chosen between 0.1ms and 1.4sec. This may be useful when you drive the plug with a expression (or midi) pedal, or, for automation strips in Qtractor or Ardour. https://github.com/brummer10/GxSwitchlessWah.lv2 happy ducking

Secret (for a song)

by Philip Yassin

Hi list! Here is my new song: Secret <https://soundcloud.com/xaccrocheur/secret>. This morning the SoundCould announcement was retweeted by none other than Sir Stan RIDGWAY <https://twitter.com/philipyassin/status/762700853220405248>, and considering that I basically decided to become a musician while loop-listening to "Call of the West" back in 1982, there's an undeniable sense of accomplishment here, so don't kill my buzz ;) This is the 9th song in my "Faux Frogs" album <https://www.youtube.com/playlist?list=PLBvCHJWi9SXxIr3Zvv_9qygxuXv_F1pbb>, one more to go (she's been almost ready for months now) PS - if more and more people keep telling me that the lead voice is too low, I'm going to be forced to do something about it. The problem is that this very vocal take is a bit crappy (I just don't sing it really good) and if I crank it even a notch, this will show :| PPS - Everything goes into an IR modeled Lexicon 480L (using Klangfalter) <https://www.youtube.com/watch?v=cC0GNYJcL4I> and boy, I feel rich :) PPS - My new album is almost ready, greetings from the studio! -- Philip "xaccrocheur" Yassin http://manyrecords.com http://bitbucket.org/xaccrocheur / https://github.com/xaccrocheur
