Dear all
Over 6 to 7 May we’ll be running the 10th edition of the Reveil daybreak broadcast, for which subscribers to this list create the great majority of the live streams.
We warmly invite and welcome your streams for that event!
To take part in this year’s Reveil please make a stream page here: http://streams.soundtent.org/manage/streams
Many people here know more than we do about live streaming, but in case of interest there are two recorded webinars (one on building a streambox and one on mobile streaming) here: https://www.youtube.com/@sound_camp/videos
This year’s current stream list can be found here: http://streams.soundtent.org/2023/streams
Thanks and best wishes Soundcamp Cooperative

There are 4 stages to joining the REVEIL 10 broadcast:
1. Set up an account at Locus Sonus so you can stream to the Locus Sonus Icecast server 2. Set up a page for your stream to give listeners context, and for the record. 3. Run your stream and test it. 4. Plan to operate your stream between civil twilight and sunrise on Dawn Chorus Day (Saturday 6 May in the Western hemisphere; Sunday 7th in the Eastern hemisphere). These times are calculated when you make a page.

Hi all,
Just a heads up that the DACBerry 400 M for Raspberry Pi 400 (the keyboard hybrid) has a line/mic input. I would assume its powered but there’s no mention of it on the datasheet: https://osaelectronics.com/get/raspberry/dacberry/400/m/datasheet/DACBerry_4...
It also has some integrated DSP

thanks very much, Julian
looks promising!
this link refers to a 'programmable microphone bias level' http://osaelectronics.com/get/raspberry/dacberry/400/m/datasheet/DACBerry_40... so could well work with electret microphones
i don t know how to interpret the SNR figures

The Pi Code Zero’s Dialog Semiconductor DA7212 has a SNR of 90 dB ADC, 100 dB DAC https://www.mouser.co.uk/datasheet/2/698/REN_da7212_datasheet_3v4_DST_201805...
The DACBerry is slightly higher at 92dB ADC, 102dB DAC but the difference isn’t supposed to be perceivable by the human ear.

don't see that this bias level relates to the stereo line-in. I'd rather expect that it referes to the headset mic. But maybe it does, which would be good. bests, Udo
