Dear friends, I need some help. My streambox (RPI zero) dont recognize the iqaudio hat anymore. Does somebody how to solve this?

After AIR
by Grant Smith 16 Nov '21

Thanks very much, everybody, for running streams over the past two weeks. Thanks also to Locus Sonus for accommodating our attempts to broadcast 'soundscapes of the COP' - which we hope widened but sometimes no doubt over-stretched the creative frame of this project. And thanks for listening bw grant AIR

As if radio -- COP26 Glasgow -- call for streams
by Grant Smith 10 Nov '21

10 Nov '21

Dear list We're contributing to this project from 31 October to 12 November, proposing a mix of live environmental sounds, sound / transmission artworks, commentary and reports from activities happening in Glasgow and beyond. If you are interested to run or refresh a stream or set up a new stream in relation to the concerns of the project, we would be very happy to include this work in the schedule, which is coming together now. Read the call (still open for proposals) https://mailchi.mp/7027cb4b175a/air <https://mailchi.mp/7027cb4b175a/air> We were thinking, if it is not feasible to run a stream for the 2 weeks of the event, we could agree on which days or nights a stream might feature. We have a lot of airtime, so there is potential for long term listening to sounds of places in real time, which some of us here clearly like..

Thanks very much, Trevor That sounds really promising. As you say, there are good databases of birds -- xeno-canto is actually pretty global in scope. Other sounds are probably less well organised. We have contacts on this topic. It might be interesting and useful to think how they might be in touch - some kind of seminar in real-time ecoacoustic analysis by AI? bw g > On 24 Aug 2021, at 16:14, Trevor Hebert <thebert(a)stanford.edu> wrote: > > I'm currently working with some CS students on a somewhat similar system, except it monitors and detects wildfires. That effort should produce a pretty good conceptual framework and probably some useful code as well. The hardest part will be to acquire sets of training data to teach the AI how to identify sounds. Some areas, like North America and Europe should already have pretty good libraries of bird sounds. Insects? Amphibians? Mammals? Anthropogenic sounds?

Solicitud de apoyo para transmisión canto de Ballenas
by Leonel Ramiro Vasquez Zarate 27 Aug '21

27 Aug '21

Buenas tardes queridos colegas de locución, Escribo este correo para pedirles apoyo en la transmisión qué haremos en el Pacífico Colombiano el día 10 de septiembre a la 1pm. Se trata de un concierto para el mundo entero del canto de las ballenas jorobadas que arriban a estas aguas cada año. La comunidad local y un grupo de amigos estaremos facilitando los equipos de registro subacuático. Nos preguntamos si es posible a través de su plataforma poder hacer la transmisión de este hermoso evento submarino. He estado haciendo pruebas y veo que con facilidad se cae la señal, no sé si sea posible para ese día garantizar una buena capacidad para un número amplio de usuarios indeterminados, y que otras recomendaciones nos puedan dar para poder evitar problemas técnicos en la transmisión. Les agradezco su escucha a este mensaje y su colaboración en esta bella iniciativa. Les dejo con una grabación de este lugar hace un tiempo. Quedo al tanto de su respuesta, Leonel Vasquez Artist Sonoro www.leonelvasquez.com

Hi Trevor and thanks for getting back to us. Concerning the issues during Reveil, thank you for pointing this out and yes we are aware that there where problems and apologise if it spoiled the event for anyone. It was due to two factors - one is that the service provider has limited the traffic to the locus mountpoint - we were not aware of this before (possibly becasue we had never hit the limit ) but it is rectifiable by announcing upcoming events to Creacast.com.

streambox noise issues
by aid 23 Aug '21

23 Aug '21

Hi, I have installed a streambox on Sherkin Island off the coast of Cork, Ireland. When I installed it, it was very windy, and I didn't get to do a proper sound check in situ. Stream is here: http://locus.creacast.com:9001/sherkin_north_shore.mp3 There is some quiet digital noise in the background. the streambox is mounted distant from the mics. I have SSH access. is there anything I can tweak remotely to address this noise? Thanks! Aidan
