Music Made With Linux - Evergreen - I'll Get To You

by Glen MacArthur

Hi fellow LAU's Over the past summer I had the opportunity to co-produce an EP in our new 'Bandshed' studio with the band 'Evergreen' which my son drums in. It was a great learning experience and they are a talented and funny bunch of guys aged 17-19. They brought the songs and performances and I did the recording mixing and mastering... Unsurprisingly we used AV Linux 2016 and various builds of Mixbus 3 to complete this project and the main interface used was a Presonus 1818VSL. This is the first released single 'I'll Get To You', it has a curious balance of a super tight rhythm section and bare-knuckled bar fight vocals and guitars, precisely the kind of thing that makes these guys unique and fun to work with... https://soundcloud.com/evergreen-548575357/ill-get-to-you

job opportunities in Germany - hearing research

by Giso Grimm

Dear list, I'm happy to announce two open positions in our group at Oldenburg University and partner institutions: NIH-funded software engineer for 5 years (audio signal processing, computer science, communications engineering, or similar) at HoerTech gGmbH, a transfer institution of Oldenburg University, see http://www.hoertech.de/de/hoertech/karriere.html for details, deadline Sept. 30th NIH-funded PostDoc position until 06/30/2021 in the field of Signal Processing for Hearing Devices at Oldenburg University, see http://www.uni-oldenburg.de/stellen/?stelle=65009 for details, deadline Sept. 20th Especially the software engineer position is based on open source audio software development on Linux; we presented the basis of that position at the LAC2009: http://lac.linuxaudio.org/2009/cdm/Friday/07_Grimm/07.pdf Our group on Auditory Signal Processing (head: Prof. Volker Hohmann) https://www.uni-oldenburg.de/en/auditory-signal-processing/ is active in bridging the gap between basic research on perceptual principles in hearing and applications in hearing devices. The group offers a creative and collaborative research environment within a large hearing research cluster http://hearing4all.eu/EN/ Best regards, Giso

Childrens educational media and youtube promotions

by Patrick Shirkey

Hi, We are working on a new project that is focused on childrens education and language learning tools. RauRau TV http://raurau.org https://www.youtube.com/channel/UC6uUlBbtctR6jIzl9eV6iww Of course everything is done with Linux Multimedia tools. We need some community support so that the youtube search ranking algorithm(s) will give priority to the channel. It would be very helpful if y'all could like/subscribe/comment/share/link to the channel. In return I will be happy to do the same for your videos and assist with promoting via the "Linux Music Videos" playlist. https://www.youtube.com/playlist?list=PLGRkb-jpsg0XYGVkE1zpJzQtwrEGKBYO6 and also at the Linux Music Videos blog: http://videos.linux-audio.com Please contact me directly or leave a comment on the videos and I will link back to you. - It should go without saying but if you want to collaborate (with profit share) on new content for the channel please contact me directly. -- Patrick Shirkey Boost Hardware Ltd

Writing midi events via Alsa/Jack

by Bill Purvis

Dear LAU friends! A long time ago I acquire a Korg X5DR synth module. I then wrote a simple midi sequencer that wrote stuff out to the module via the serial port (the X5DR has a 56Kb serial input in addition to the conventional 32Kb Midi ports). This worked fine and I had lots of fun playing it. Things moved on and my machines now no longer have serial ports, but a USB/Serial adaptor cable got me over that one. More recently again, things have on a lot, and after a certain amount of trial and error I managed to adapt my sequencer to talk to to Yoshimi via Jack using the Alsa routines and QJackCtl to set up the links. One odd thing I noticed was that QJackCtl shows my programs output port and the Yoshimi input ports on the ALSA page, rather than the MIDI page. I now want to connect up the Calf Fluidsynth, but that shows the input ports on the MIDI page. Anyone with enough knowhow of programming the ALSA interfaces willing to sort out my problem? My present code for setting up the port has: out_port = snd_seq_create_simple_port(seq, "MFE: output port", SND_SEQ_PORT_CAP_READ|SND_SEQ_PORT_CAP_SUBS_READ, SND_SEQ_PORT_TYPE_APPLICATION); which sounds odd (READ?) but I gather the parameters actually specify the far end, rather than the near end. I'd like to be able to use this with Fluidsynth and Yoshimi it different times, but I guess I'd need to have a command line option to vary the code to get the different class of outputs. Any pointers to something that can explain the difference between the two categories would be most helpful Many thanks Bill -- +----------------------------------------+ | Bill Purvis | | email: bill(a)billp.org | +----------------------------------------+

minimize clipping in pico2wave text-to-speach

by Amie Amaman

Dear linux-audio-user list, I am using pico2wave on Debian 8 to synthesize voice from text. I encounter the problem that in the wav file which is produced, there is clipping, regularly producing harsh scratching sounds. I've downloaded the source code of the Debian packages "libttspico0" and "libttspicl-util" (containing pico2wave) but I am an absolutely lay person (I'm not even sure how to install the modified source as a Debian package, but this problem I'll address later on...). Can anyone of you tell me which line of code I have to edit to make the voice production lower (and by that minimizing the clipping)? (or maybe how to increase the maximum volume capability of the wav file as an alternative?) Any help is appreciated. Apart from the clipping the pico voices are quite agreeable to listen to, so I really want to get this done. Regards! Amie

[linux-audio-user] Sub-harmonic generator? (LADSPA or VST)

by Tim Howard

Hello, Does anyone know of a good plugin that will generate subharmonics? I would like to put a little more low frequency "oomph" into my bass track. Preferrable LADSPA, but VST would work, too. Thanks for any help! -TimH

Yoshimi 1.4.1 - Lyrebird.

by Will Godfrey

Maybe not be the prettiest, but this bird sure knows how to create great sounds! First of all, we have a new quick guide that's in Yoshimi's 'doc' directory. It's just something to help new users get started. We've always logged warnings if it wasn't possible to run either audio or MIDI, but now we also give a GUI alert. From this version onward it is possible to autoload a default state on startup, so you have Yoshimi already configured exactly as you like, with patches loaded and part destinations set etc. To make it easier to position program change CCs in a MIDI file, there is a new option to report the time these take to load. Vector control settings are now stored in patch set and state files. We implemented a simpler way to perform channel switching so the 'current' MIDI instrument can seem to be changed instantly, but retaining the note tails of the previous one. All the usual background improvements. When installed, full details are in either: /usr/local/share/doc/yoshimi/Yoshimi_1.4.1-features.txt Or: /usr/local/share/doc/yoshimi/Yoshimi_1.4.1-features.txt To build yoshimi fetch the tarball from either: http://sourceforge.net/projects/yoshimi Or: https://github.com/Yoshimi/yoshimi Our user list archive is at: https://www.freelists.org/archive/yoshimi -- 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.

Audio interface

by Max

I have a Fireface UCX, but I never actually use it to full potential. I have an opportunity to sell it now, but was wondering what I should get instead. Requirements: USB, 4 channels, Linux compatible, low latency. Thanks for your suggestions.

Still love Fuzz

by Hermann Meyer

Since I was a little boy, I love fuzz. A lot have changed over the time, one can say I'm established this day's, true, maybe. One can say I'm not the revolutionary from the old day's any more, may be true as well. But, this one thing for sure has left, I love Fuzz. :-) https://github.com/brummer10?tab=repositories regards hermann
