It's tricky getting everything to fit in 512K RAM - I think the new
ESP32S3 has the same memory size, so that will be the limiting aspect.
On the ESP32-S2 it's possible to use up to 4MB of external RAM:

Still not a lot, but better than 512KB :-)

Yeah, AOO on RTOS will be cool! For that we should drop bluetooth
in favor of some flavor of WIFI I think.

Cool, that's excellent news. I'm using the ADF i2s audio driver but staying
away from their "streams" since they're too clunky (and they eat memory). I
have only audio, bluetooth serial emulation, and SD card filesystem, no
threaded readsf or networking (probably too memory-intensive again).
Starting with the DIYasb [1], distributed streaming devices for field
recording and audio projections using Pd, want to include the AOO-Streaming
[2] functionality, already tested and used also for VRR [3] now for ESP32xx
devices, especially simple Ambisonics Mics and field-speaker for a future
project.
Doing simple streaming over WiFi, I did not get any trouble using opus lib,
but did no extensive processing until now and allowed enough latency for these
applications, but have to dig in deeper... not using bluetooth and waiting for
the ESP32S3...
I had to go way out on a Pd branch to get it running, but I want to rebase
all that once I get the Pd source in better shape to support it.
thats fine, please keep us updated.

Hello,
Before doing that I want to do some reorganizing - in porting Pd to
FreeRTOS (so I can run it on an Espressif LyraT board, which I think
takes only about 10 or 20% of the current that a Pi needs) I found out
that I had to move a few functions from one file to another.
That is really exciting news, since I do most physical project on ESP32xxx
for distributed computermusic projects from speaker to robotic
instruments.
So please let us know how it progress if you need for testing debug or
other helps. Maybe can help with objects helping interfacing the
Peripheral possibilities, from touch to solenoids drive...
Are you targeting the ESP-IDF/ESP-ADF framework ?
