Hello all
This seems like a really interesting and significant discussion, both in terms of the REVEIL project for a 24 hour daybreak broadcast scheduled for next May, and more generally for the directions of live audio feeds..
Compared to when Ragnar Olafsson did the daybreak forever installation a couple of years ago, there seems to be a proliferation of approaches and devices to supplying live audio streams.
I am in the process of collating recipes on this, so is great to hear about these below, and any others out there..
Of course some mobile streams are ephemeral and some permanent streams are dispersed: like Patrick Perdue's stream which I at least wasn't aware of.
For iphone, it seems the iphone 3GS is the first model to support the koalaSan and audiobus approach; so in not too long there will perhaps be many such machines around which could potientially be re-purposed for live streaming, in a twist on the audio ecology monitoring project announced recently on ars technica http://arbimon.com/arbimon/index.php/home-acoustics
This might have advantages over the pi kits which Gregoire is using http://locusonus.org/w/?page=Proj+Lauvin but also maybe not.
In general there are probably lots of possible approaches for different situations.
A key aim emerging for REVEIL is to encourage participants in the direction of a more permanent installation, via the locus sonus network, so we are building something more than a one-off event.
If it is the case that there is now a proliferation of live audio feeds, maybe we should also be working on a place to present these diverse live materials - a paradoxical live archive? arklive? - where they can gain from association with others.. similar to the way small sites of high biodiversity can benefit from being mapped together with other such sites.. as at aporee for recorded sound
thanks

You can do something similar with KoalaSAN and AudioBus, optionally mixing in the audio source of anything that supports AudioBus. I use BossJock Studio as a front-end processor for live input for compression/limiting from my Tascam IXJ2 before it hits the stream. Also, I have never tried using something like the Zoom H1 with an iPad/camera connection kit, but I can tell you that any of the Olympus recorders I have (LS100, LS14, DM520) won't work. Same for the Zoom H4N I had for a short time. I wasn't impressed at all with it's preamps compared to the original H4. And, of course you can't use any of these devices directly from an iPhone due to Apple's power restrictions, at least without jailbreaking. I even tried a Blue Tiki, which has some processing in-line with two mic capsules (mono, used for noise reduction,) and even that went over the 20MA power range.
I don't have any Android devices at all.

Patrick Perdue:
Isn't there a way to make USB audio input work on Android devices running 4.1 (or is it 4.2) and higher?
yes, host mode is told to work on 4.1. or so, usb audio out too, but havn't found success reports on sound cards, or recorders acting as such (olympus, zoom, etc.) a nice streaming software for androids is "broadcastmyself"... it optionally mixes mic-in with a playlist

but I prefer my Tascam IXJ2 and an Audio Technica AT-822 with iPhone for portable streaming applications. I use an app called KoalaSan on iOS for remote streaming. It supports Ogg Vorbis, Opus and AAC. Opus requires IceCast 2.4.
The stereo image is wider on the AT-822 than the IXY. I don't think any of the current Audio Technica microphones have such a nice image as the AT-822, although some are technically superior in terms of SNR and sensitivity. A real shame.

Some of those are likely to be resolved by the new Raspberry Pi streamers which Gregoire has up and working. They have the potential to be an affordable reliable successor to the Streamboxes for a new generation of streams.
At CRISAP in London we are planning a workshop to get people started building Raspberry Pi streamkits. It would be good to hear from people interested in that - which could also be expanded out to other places
hello Grant et al,
are there any howtos etc. on building a streamer with rasPIs? i know that it's not so difficult, but it would save some time. there was some discussion on running liquidsoap on a PI powered by a solar panel.
if only android phones would support external mics like the rode ixy for the ifon, that would be a perfect solution for ad hoc streaming in reasonable quality.
