[LAU] [music] A Castle in Bohemia (Reface DX-Mas)

by Christopher Arndt

Here is a late musical seasonal greeting to Linux Audio. (I wrote and recorded this track already on Christmas Day and intended to improve the mix before publishing, but since I have to work this week and it would probably not get finished until next year, I decided to put it out as is.) **The theme to a soppy Christmas television mini-series from the eighties that never was** Soundcloud: https://soundcloud.com/spotlightkid/a-castle-in-bohemia Ogg Vorbis download: https://0x20.eu/nc/s/RFBjkL6kFacMWo9 FLAC download: https://0x20.eu/nc/s/wbY7HjTB2fYwyT8 Synopsis: A young woman from western Europe spends a year in communist era Bohemia (then Czechoslovakia), where she has family ties, as a farm hand. She lives on the premises of a small castle, which belongs to an impoverished family of aristocratic roots. When she meets the young son of the family, their initial mutual attraction is cut short by misunderstandings caused by prejudice and differences in upbringing. Over time though, he wins her heart by showing her the beauty of the Bohemian country side and the joys of a simple rural life while she enchants him with her classical flute playing and brings him to overcome his introvert nature by introducing him to Italo disco dancing. :) Composed and produced by Christopher Arndt on Christmas Day 2021. Recorded in Ardour 6 DAW on Linux with a Yamaha Reface DX FM synthesizer into a Focusrite Scarlett 6i6 audio interface. No samples, no filters, just one synth. Reface DX patches by Christopher Arndt and from SoundMondo.com (list on request). Some EQ ("EQ10Q") used on the horn sound, IR reverb using "LSP Impulsnachhall" and Samplicity M7 "Boston Hall A" impulse response, and multi-band EQ and compression on master bus using "ZamAudio ZaMultiCompX2". Share & Enjoy! Chris

Returns the same information the older script did. Although I installed the Q1 GUI, how do you run it? Not important, I prefer the script, but just asking. -- David W.

[LAU] Interpretive audio to video?

by James Greenlee

Does anybody know of a tool that I could feed audio in to, and have it output an "interpreted" video? Not necessarily a "waveform" of the audio, more something abstract, like an acid-tripped audio fractal or something. Thanks!

[LAU] Rumor - nasty growling bass fuzz pedal

by Hermann Meyer

I've just push my latest work to github, It's a pure, nasty growling bass fuzz pedal, with bold out-front presence, and cutting articulation. It's for those who love those good old transistor based fuzz pedals. https://github.com/brummer10/Rumor <https://github.com/brummer10/Rumor> rooowwwaaa a a a a a a a

[LAU] [music] Oscillator - Pandora (remix)

by Jeanette C.

Hey hey, I had the great opportunity to remix a song by Oscillator (Staffan Melin). Here's the Linux musician's thread with the original: https://linuxmusicians.com/./viewtopic.php?f=9&t=23954 Here's my remix: https://youtu.be/yPYko4vuvEk and a direct OGG version: https://www.dropbox.com/s/n05lejzwj0851t1/pandora_mix2.ogg This song uses samples from Missa pro defunctis - 1. Requiem by permission (CC BY 3.0), see https://musopen.org/music/44142-missa-pro-defunctis/ Vocals performed by Kajsa Olsson This remix uses a few of the arpeggio rhythm sounds from the original, re-recordings of pads, bass and some arpeggio/sequence style sounds to allow for slightly adapted harmonies. :) The drums are completely new. Besides some hardware for the monophonic sounds, there is a lot of Yoshimi for the three pads and two choirs. There is also Aeolus. I always wanted a good place for Aeolus in a popular production. None better! The drums are a mix of samples loaded into LinuxSampler, partly sampled from hardware, partly synthesized in Csound. The processing is rather heavy duty, but quite conventional. Lots of use for SWH (Barry's Satan maximzer! :) ), CAPS, TAP, Calf, Invada and Fons' g2verb, zita-reverb and parametric 4-band filter. Enjoy and best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Don't, don't let me be the last to know Don't hold back, just let it go <3 (Britney Spears)

[LAU] setBfree: Gain sweller from lin to log characteristic

by Gerhard Zintel

Dear list, I'm mainly using Pianoteq and setBfree for live performance. To quickly adapt my sound volume of both SoftSynths together I'm using a foot pedal to send Midi volume commands to both applications. Unfortunately that is not working very well for both programs are using the Midi volume values (0-127) differently. Pianoteq adjusts its output volume according to a more logarithmic manner while setBfree seems to handle it linearly. Thus if I adjust both volumes to a similar SPL for Midi value = 127 the organ is way to loud at lower levels compared to Pianoteq. Meanwhile I have found the location in the source of setBfree where I could make adjustments. I have measured the logarithmic dependency of Pianotec's Midi to volume characteristic and found a formula to be used in setBfree to get a similar performance. It would be nice if this could find its way into the original source. Now I have the following questions: Does anyone of you know if the original swell pedal of the B3 is changing the volume in a linear or logarithmic way? Maybe if the original B3 uses a linear characteristic we should not change setBfree's code. The function I'm using is mimicking Pianotec's characteristic. Maybe there is a more global approach for changing from linear to logarithmic behavior over Midi volume values? Surely for me it's ideal when both Synths have same characteristic. Do you know a source where I can find more general info about lin<=> log conversion of Midi volume in software? How is it handled in other professional programs? I know that every amplifier uses a logarithmic pot for volume control to follow more the human loudness perception. Do you think its worth the effort to send a patch to github's repository (I've never done such a thing so far)? Thank you for your time Gerhard

[LAU] Multi-channel (3 or more) audio playback with alsaplayer

by Kamil Adiloglu

Dear group, I would like to use alsaplayer via jack to play 3-channel audio files. These audio files will be routed into a real-time capable signal processing platform the open master hearing aid (openMHA). However, I cannot route the third channel to jack. I try to start alsaplayer as a daemon with the following command alsaplayer -i daemon -s PHL -o jack -d MHA:in_1,MHA:in_2,MHA:in_3 -F 16000 However alsaplayer returns and error saying cannot connect output port 2 (MHA:in_2,MHA:in_3) Actually MHA:in_2 should be the output port 2 and MHA:in_3 is ment to be the output port 3. I first start the openMHA software so that it establishes 4 input and 4 output connections via jack with the sound hardware. I can see the connections on qjackctl connections window. I have a sound card that has 8 input and output channels and the openMHA is configured to expect 4 input channels and produces 2 output channels and already mentioned. So, the problem is neither on the MHA side nor on the hardware. I am afraid that I cannot configure the alsaplayer correctly that it expects three (or more) output ports. I would appreciate any help from your side. Thank you in advance. Best regards, Kamil

[LAU] [music] Tidal wave (something different, more proggy :) )

by Jeanette C.

Hey hey, I tried my hand at some prog and found the result to be a mix of classic progrock, prog metal, soundtrack and jazz fusion. Also except for the two analogue leads, everything is Linux softsynths. LinuxSampler, setBfree and Yoshimi for the puls and pads. https://youtu.be/yI5w-IVeulc Direct ogg: https://www.dropbox.com/s/scfpw8dm5d7jed4/tidal_wave.ogg I hope I forget none of the fun ingredients to make a captivating, living prog piece. Enjoy and know that every feedback is always welcome. :) Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c When you need someone, you just turn around and I will be there <3 (Britney Spears)
