I'm trying to use the existing java code as my guide, for the csnd.jar
wrapper. However that's not enough for an android port for realtime
audio. If you are compiling to wav and then listening to the results
you can get away with a csound port with no audio support, and the
playback happens after compilation. That's one approach, but it
doesn't take advantage of the power of my android tablet.

Michael Goggins has a working approach, although I can't get the
Silencio scripts to run on android yet.

What would be necessary is to add support for Open SL ES realtime
sound output from csound, so you have a port of csnd.jar for dalvik so
java developers can then use csound as their backend synth engine and
build front ends for it.

People who only have an android 2.2 device likely don't have enough
firepower to run csound in realtime on their device. But tons of
android devices are fast  enough to run it in realtime, at least a
port of the OLPC version of csound with java/dalvik bindings rather
than python bindings.

That way you only need to support Open SL ES for realtime audio
output, you don't have to send audio back through JNI as with 2.2 and
below.

Hi Brian,

I'm already very far on with this.  I have csnd.jar and libcsound
compiled for android, but we ran into a snag where we had to get rid
of use of temporary files by csound when parsing orc/sco.  John took
care of that (you could actually not even use orc/sco/csd files and
just pass in strings for those via API) by redoing some internals to
csound though the latest I tried with my compile still crashes out
somewhere.  Otherwise, Victor has some custom OpenSL code and I wrote
a custom AndroidCsound class that subclasses Csound and handles
setting up pointers for audio callbacks.  So we're working on it, but
it's crashing at the moment and I'm going to be off and on online this
week through Saturday (taking a small holiday with my wife).  I'm
guess once we can get to rendering and procesing audio live, it'll
still take a little bit of time to make sure everything is working
correctly and to do documentation/examples before an official release.

Thanks,
steven

Steven and Brian,

the new string code is OK and now csound is running well, so it is likely that when Steven and I get together in a week or so, 
we will be able to progress the Android code. 

Regards

Victor

steven (and all the others involved in this project) -
i just want to appreciate your work on this. it's so important for the
future of csound! though i do not have any mobile device like this, i
think i will buy an android if csound is running there.
thanks -

And related to this, I had the pleasure of getting Csound on iPad and iPhone demonstrated here in Trondheim today. It is totally great. Victor was here for a workshop we organized (DSP Ear Training). It is very very inspiring to see Csound find it's way to these new areas and new platforms. We'll for sure invent applications that makes good use of it, that spreads the word and the sound and the tool to new users.

I'm more interested in the "DSP Ear Training" part of this mail. We
discussed it briefly at the LAC. Do you plan to put any material/info
online? I think it's a great idea.

Thanks, yes we will make online materials.
The course materials are planned as open source and free resources,
there might be a small administrative fee to follow the course and get
academic credit etc.

The planned materials include a short lesson on each dsp technique,
with flow chart, audio graph display, csound code, and listening
examples.
There will also be music examples to show examples of each technique
used in released productions,
and we are building "listening tests" where you are challenged to
guess the technique and parameter settings used to produce short audio
clips.
We actually have an automatic listening test generator ready
(collecting a csound csd from include files covering most dsp
techniques (27 effects for now) currently included in the course. We
are also working on a "reverse engineering" listening task where you
shall try to tweak parameters to approximate a given sound.
I the workshop we worked on perspectives on ear training, terminology
for describing timbre, e-learning, automatic tutoring, selection of
dsp techniques to include, music examples, audio programming and
deployment, web framework for the course etc. In addition to Victor,
we were Sigurd Saue, Bernt Isak Waerstad, John Paal Inderberg and Jan
Tro (all NTNU), Joran Rudi and Notto Thelle (Notam), and Haakon Kvidal
(Norwegian Academy of Music).
I will of course keep you posted, and hope to get feedback on the
material when we have collected it in a presentable manner (during
spring 2012).

best
Oeyvind

This sounds like a fantastic project, and I'm sure it will be a very
valued resource by all.  I'll be looking looking forward to how this
all develops!

>>> And related to this, I had the pleasure of getting Csound on iPad and iPhone demonstrated here in Trondheim today. It is totally great. Victor was here for a workshop we organized (DSP Ear Training). It is very very inspiring to see Csound find it's way to these new areas and new platforms. We'll for sure invent applications that makes good use of it, that spreads the word and the sound and the tool to new users.
