Re: [locustream mailing list] config for iqAudio Pi-CodecZero
by aid 06 Jan '22

06 Jan '22

Grant suggested I try some changes, and this is what I've done: In /boot/streambox.txt - changed to soundcard=0 - Added login, wifi details In /boot/config.txt - added dtoverlay=iqaudio-codec In /etc/dhcpcd.conf - added static domain_name_servers=8.8.4.4 8.8.8.8 Also verified that the streambox server comes up on a different rpi, so the config is correct, it's just not working with the rpi zero w? is there a system change that breaks wifi for my rpi zero w maybe?

There are a number of alsamixer settings to play with, so maybe the wifi noise can be eliminated there. Also I'm testing this beside a mess of synths and electricty so maybe i need to move the streambox somewhere less noisy. to bring up the box was as follows: changed in /boot/config.txt: #dtparam=audio=on dtoverlay=iqaudio-codec then, copy the IQaudIO_Codec_StereoMIC_record_and_HP_playback.state file to the streambox, ssh and sudo alsactl --file /home/locusonus/IQaudIO_Codec_StereoMIC_record_and_HP_playback.state restoresudo alsactl store will report if I can resolve the wifi noise issue. | | | | | | | | | | | iqaudio/Pi-Codec Tools for the IQaudIO Pi-Codec / CodecZero sound cards - iqaudio/Pi-Codec | | | On Wednesday, 6 May 2020, 14:12:38 BST, aid <oootini(a)yahoo.com> wrote: Hi folks, trying to set up an iqaudio Pi-CodecZero as described by Udo some days ago.

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?

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 <http://creacast.com/>. The other problem is due to the architecture of the timeline page for Reveil which means that everytime someone updates the page it pings all the mountpoints including those which are not active because destined to be used for a performance at a specific time. We will fix these issues before the next soundcamp reveil. In the meantime it shouldn't be a problem for the soundwalk we are planning which is spread over several weeks (we are not expecting thousands of users at the same time). >>> >>> Thanks for you help, >>> >>> Best >>> Peter >>> >>> Le 19/08/2021 à 17:21, Trevor Hebert a écrit : >>>> Hi Peter, >>>> Our mic is always on and always happy participate in streaming events: >>>> http://locus.creacast.com:9001/jasper_ridge_birdcast.mp3 <http://locus.creacast.com:9001/jasper_ridge_birdcast.mp3> >>>> >>>> I've noticed during the last two Reveil events that LocusSonus has some kind of performance/capacity problem that impacts some streams, including ours.
