Hi,
and tried to install aoo via deken, but it does not show up
that's weird. You should get
aoo[v2.0-pre2](Darwin-amd64-32)(Linux-amd64-32)(Linux-arm64-32)(Linux-armv7-32)(Linux-i386-32)(Windows-amd64-32)(Windows-i386-32).dek
"Linux-armv7-32" should run on the Raspberry Pi.
Can you try searching for libraries like "else" or "cyclone" which have
dedicated Armv7 versions and see if they show up?
Christof
PS: In the Deken settings you can disable "hide incompatible externals",
so the result should definitely show up in the next search.

i love that vision!

I have a mobile modular system of Raspberry Pis running PD with local
speakers and sensors , and tried to install aoo via deken, but it does
not show up. I suppose aoo currently does not run on that
architecture? (sorry, my technical knowledge is limited..)

Hi,
the first use case was an audio installation by Bill Fontana in Graz
(March - June) where we placed environmental streaming devices at 8
different places in the city and streamed the sounds to other places.
Then we used in April-June for the VRR project (https://vrr.iem.at/)
where students of contemporary classical music, who couldn't leave
their cities/countries because of the Covid restrictions, could
rehearse in a virtual rehearsal room which we've implemented in Pd.
Currently it's being used in computer music seminars where students
play as an ensemble of interconnected instruments.
The vision of AoO is that a network of computers becomes a modular
system: every device can be connected to any other device on the fly.
For example, I might want to send 5 seconds of sound to player A,
then receive 4 seconds from player B, do something with and send the
result to some (wireless) speakers, etc.
Another idea is to have an ensemble of cheap wireless I/O devices
(microphone + amplifier) running the AoO library (C++) as a portable
multichannel system.

Hi Christof,
That sounds very exciting! I’ll try this out as soon as I can.
In fact, that is one of the main use cases for this library ;-)
I’m curious, what kind of projects did you use this in?
Best regards,
Frederic

Hi,
Do you have experience with sending from one source to multiple
devices via Wifi?
Sure, we did this all the time. In fact, that is one of the main
use cases for this library ;-)
If you send within a private network, you can use the "pcm" format
for uncompressed audio, but for the public internet you might
consider using the "opus" format for substantially lower bandwidth,
especially when you're sending to many endpoints. A stereo 16-bit
PCM stream @ 44.1 kHz takes about 1.4 Mbit/s. With Opus you can set
the bandwidth to 120000 (= 128 kBit/s) and still get decent
quality. This means you can send 11 opus stream for a single PCM
stream :-)

Dear list,
here's a new pre-release for the AoO multichannel audio streaming
library. In the last two months, the library has been seen many
improvements and has been used successfully in our Virtual
Rehearsal Room project (see vrr.iem.at <https://vrr.iem.at/>).
Binaries for all common platforms (Windows, macOS, Linux, ARM
boards) are available on Deken (search for "aoo"). The source
code can be found here: https://git.iem.at/cm/aoo
See the help patches (aoo_send~-help.pd, aoo_receive~-help.pd,
aoo_server.pd) for usage instructions.
If you want to stream between different home networks (without
port forwarding), you can use [aoo_client] and connect to our
public AoO server at the IEM (hostname: vrr.iem.at, port: 7077).
You can easily set up your own AoO server by running a Pd patch
containing [aoo_server <port>] on your web server.
---
Selected features:
* create audio networks of any topology with arbitrary ad-hoc
connections
* [aoo_send~] / [aoo_receive~] take a port number and ID, so
multiple objects (within a single Pd instance) can operate on
the same port. Additionally, you can have multiple objects
across different Pd instances (using different port numbers).
* [aoo_send~] can stream to several destinations simultaneously;
* [aoo_receive~] can receive several AoO streams
simultaneously, summing the signals
* AoO is connectionless: streams can start/stop at any time,
enabling a "message-based audio" approach.
* AoO sinks can "invite" sources, i.e. ask them to send audio.
The source may follow the invitation or decline it.
* AoO sinks and sources can operate at different blocksizes and
samplerates
* the streaming format can be set independently for each
source; currently only PCM (uncompressed) and Opus
(compressed) are implemented, but this can be easily extended
with the AoO codec plugin API.
* audio encoding/decoding is multithreaded
* adjustable resending mechanism for dropped packets
* adjustable jitter buffer size.
* [aoo_server] / [aoo_client] implement the UDP hole punching
technique to establish peer2peer connections between
different home networks.
* AoO is actually a C++ library with a C interface, so it can
be used in apps or embedded devices (like the ESP32). An
implementation for Supercollider is already planned.
