[Music] Silver (my entry into this year's Nexus challenge)

by Jeanette C.

Hey hey, Silver was my entry into this year's Nexus open source music challenge https://nexus-challenge.osamc.de/ I am happy to say that it came in second. :) This year's rules said that we were supposed to compose a song in the style of another song or a musicain. I chose Imogen Heap and hope that I maybe caught it tangentially. :) https://youtu.be/vJLG409oDek This song is licensed under the Creative Commons NonDerivative 4.0 license. Silver was recorded using Yoshimi, Csound and LinuxSampler as sound engines, Midish for tracking and Nama for recording the audio, mixing and "mastering". Feedback is welcome. To spare you one bother: I know that my vocals are substandard. :( Best wishes and enjoy all the same, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * SoundCloud: https://soundcloud.com/jeanette_c * Twitter: https://twitter.com/jeanette_c_s * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Our imagination Taking us to places We have never been before... <3 (Britney Spears)

Jconvolver output format

by bricolodu

Hello, I have a setup that is running fine with : Raspberry Pi (I2S) / Squeezelite / Jack / Jconvolver / I2S DAC I have another DAC Chip, that I want to use, however it is not I2S, it is Right justified. I though that i just had to change the driver on the Pi from I2S to RJ but it doesn't work that way. It looks like the format should be changed at the output of jconvolver. Can someone confirm ? How could I change the audio format from jconvolver ? Best regards, Jean -- Sent from: http://linux-audio.4202.n7.nabble.com/linux-audio-user-f5.html

Streaming low-latency bi-directional audio between Android 4.x and a Linux desktop

by Stuart Longland

Hi all, Firstly, apologies if this is not quite relevant to this list. I'll happily take it elsewhere if this is the case. I was wondering if someone knew of a tool that would enable me to connect my phone (running Android 4.1, I know this is old but it's what I have) over WiFi to my desktop (Ubuntu 18.04 LTS) or my laptop (Gentoo). I have a proof-of-concept going using JACK, icecast2 and darkice… I was able to get `qt-dab` to pipe audio to `darkice` and receive the stream from my phone using `HaveRadiosion`, however there's quite a bit of latency introduced, and it's one-way. Fine for music, but if I'm in a VoIP call with someone and have to step away from my desk at work I'm kinda stuck. Both JACK (netjack[12]) and PulseAudio are able to operate over a network. It seems all I really need is a compatible Android application that can link to the phone's headset and advertise that to the PulseAudio or JACK server. Before I go embark on a quest to scratch my own itch, is anyone aware of software that would allow such a link to take place? Regards, -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.

Sonic Visualiser v4.0 released, along with Tony v2.1 and Sonic Lineup v1.0

by Chris Cannam

I'm delighted to announce new releases (made last Friday) of Sonic Visualiser and two related desktop applications from the Centre for Digital Music at Queen Mary, University of London: Version 4.0 of Sonic Visualiser, a free, cross-platform, open source application for viewing and analysing the contents of music audio files, is now available. The main change in this release, and the reason for the major-version bump to 4.0, is the addition of a "boxes" layer used to annotate and export time-frequency regions. (Refer to https://www.sonicvisualiser.org/doc/reference/4.0/en/#boxes for a description of the boxes layer.) See the home page at http://sonicvisualiser.org for more information and downloads. Version 2.1 of Tony, a free, cross-platform, open source application for high quality pitch and note transcription from solo vocal recordings, is now available. This is what you might call a "consolidation release" - it is almost unchanged from 2.0 in terms of features, but it is updated to fix some compatibility issues that have arisen since 2.0 came out and to prepare the codebase for a future feature release. See the home page at https://www.sonicvisualiser.org/tony/ for more information and downloads. Version 1.0 of Sonic Lineup, a free, cross-platform, open source application for comparative simultaneous visualisation of multiple audio files containing versions of the same source material, is now available. See the home page at https://www.sonicvisualiser.org/sonic-lineup/ for more information and downloads. Chris
