or lash out on a $35 wolfson card if you need stereo in and out plus more, and
want to avoid the usb.

certainly the Raspberries are cheaper than the Udoo, even with this card
included ... but 3+ x the price of a Raspberry does get you a lot more computing
power (4 much faster CPU cores plus an Arduino Due core with all the analogue
and digital IO exposed and internally connected ... and the GPUs have openCL
available and much more comprehensive documentation if you want to use them at a
very raw level). There are much better peripherals included if you need that.
Not sure yet how the audio noise compares between the wolfson, plain raspberry
and udoo but will test and report eventually

I ordered one the other day, so I'll definitely test it, too.  (I've
never played with an RPI before, so I'll probably doing some general
playing around before getting to Pd specifically.)

They are good value and compact, but rather limited compared to units that cost
a bit more. I've done a few projects, they are probably most useful for video
playback and working with GPIO input, the wolfson card may make them good for
stereo audio also ... but the access to the GPU is fairly closed and I've
struggled to get them to do what I want, kind of got there ... certainly playing
a single HD video with sound through hdmi is good, 3D mapping is possible, also
alpha overlays ... but it is still very much custom per project at the moment
for me. Playing HD is very much at the limit of what they can do and requires a
lot of tweaking and compromises depending on what is wanted each time. They can
do more at lower resolutions. Documentation beyond the sample code is limited.
The GPIO stuff has some nice libraries and works well.

Sometime later this year I'll have something more generalised and usable that I
can share, but for now it really is too messy.

It is included in Pd extended normally.
You can use Pd-ext or its readanysf~ binary if you use Pd vanilla 32
bits 0.43+

I just checked the current Pd-extended.dmg and it does not come with
[readanysf~]. It would have surprised me if it would, since Pd-extended
for Linux and Windows also does not ship with [readanysf~].

BTW: It seems [readanysf~] doesn't work properly on Windows, too. After
having added zlib.dll to and copied pd.dll to C:\Windows\syswow64
(Windows 7 64bit), I was finally able to successfully load [readanysf~],
but it wouldn't play any files (or at least not any mp3 files). It said:
Invalid file format or unsupported codec. This seems expectable, since
the readanysf~ binary isn't linked to any decoder library like
gmerlin-avdecoder.
