[LAU] OT: Amazon Lab 126 and Linux

by Peter P.

I just came across this job posting https://www.amazon.jobs/en/jobs/894336/applied-scientist from Amazon Lab 126 and am positively surprised that they are asking for experience with Alsa, Linux and realtime systems. Lab 126 seems to be an R&D lab contributing to products like Kindle, Fire tablets, Fire TV and Amazon Echo, the speaker for their Alexa service which suffers from severe privacy issues, see https://en.wikipedia.org/wiki/Amazon_Alexa#Privacy_concerns Does anyone know if any of these devices are using Linux as their OS? A quick online research did not confirm nor deny this. Despite Echo/Alexa being a questionable product in my view, as for example described in https://www.engadget.com/2019/04/30/hey-alexa-how-can-we-escape-surveillanc… it would be a great example of widespread use of Linux in an audio product.

[LAU] Immersive Audio, ADM and MPEG-H

by Christoph Kuhr

Hi *, I am attending an MPEG-H workshop with the Fraunhofer IIS Soundlab. MPEG-H shall be used for immersive audio and assistive technologies in DVB technologies (and hopefully more). At the moment, there is no Linux plugin. Only au and vst. But, an engineer of Fraunhofer offered me that he would initiate a Linux plugin development if I can find more then three people, who are interested. I took this bet! So please support me! :-) BR, Ck

[LAU] A bit of 2013 nostalgia!

by Louigi Verona

Hey everyone! I have recovered three tracks that I made during LAC2013. Restored from their sorry state to something more palatable, these 10 minutes of music will allow you to join me on this nostalgic journey and reminisce about times long gone! https://soundcloud.com/louigiverona/sets/lac2013 On track one you can hear samples taken out of the lecture by Rui on QStuff, which I recorded with a mic right there and immediately incorporated into the music. "You are the user!" This is true Linux Audio community lore :D Louigi Verona https://louigiverona.com/

[LAU] [Music] Prophetess on holiday

by Jeanette C.

Hey hey, a new synthpop tune. Someone said it sounds 80ish, although I aimed for the naughties. It's all one hardware synth, sequenced, recorded, mixed and master in Linux with my usual setup. youtu.be/p_dol1TI13Y I hope you enjoy it, whether for its sounds or the music. I'm looking forward to your impressions, if you have any. :) Best wishes and enjoy, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * SoundCloud: https://soundcloud.com/jeanette_c * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * GitHub: https://github.com/jeanette-c * Twitter: https://twitter.com/jeanette_c_s I believe We all have one true love Somewhere in this world <3 (Britney Spears)

[LAU] [music] 50s/60s parody: at Gringo's cantina

by Jeanette C.

Hey hey, while on holiday we have recorded a simple little song, which is a 50s/60s parody in many ways, though a fine sounding one. :) https://youtu.be/h2ku70f25-Y It was recorded using mtron pro 2 software from within Ardour, processed with the Overtone DSP plugins and the video made in kdenlive, using a few of the video effects. I hope you enjoy it. Feedback is welcome. Best wishes, 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 When you need someone, you just turn around and I will be there <3 (Britney Spears)
