Thanks for all the replies regarding Android
latency. All very helpful and definitive.
With regard to my current project (a .csd for
performance with Victor's CSD Player app), I've found the
following:
1) SR = 8000 is the highest rate it will play
without dropouts (on Samsung Tab 2 7.0). I know this is a CPU
limitation.
2) CsOptions, in addition to -odac, *must* include:
-b128 -B2048
Without these, latency goes up to approx. 1 second! (Also, -b64
gives stuttering, so that's apparently the lower end for me.)
So, whatever the defaults are for -b and -B, they
are surely not applicable for realtime on Android.

It probably is device dependent. The big thing to note
about Android is that it is an OS. It is unlike Apple which is a single
hardware/OS base. Android devices vary greatly by CPU strength, thus
some of the challenges of app development.
Csound lib itself way outperforms what Google gave the Java developer to
work with (AudioTrack,SoundPool).

I am using this below in my header. I am not really sure how
much latency is being talked about. I know there is some but don't
see it much. I don't think it is anywhere near the 200ms stated
earlier. You should grab my app and give me your opinion on how much
latency you notice.
I am using my own custom designed controls in Android, but basically
it uses the standard Android touch framework underneath. Most of
what I used to learn how to build it was from the MultiTouchExample in the
CsoundAndroid package.
-o dac -+rtmidi=null
-+rtaudio=null -d -+msg_color=0 -M0 -m0

nchnls=2
;0dbfs=1
ksmps=64
sr = 44100

Roger (or anyone else),
Do you have any tricks to improve latency on
Android?
Any special CsOptions?
I've been using:
-odac -m0d --expression-opt -b128
-B2048

I played it. The latency was not really a
problem. fluid would be nice to see. loscil works great
also!

I see, did you play it, or somehow managed to
sequence the tracks? I am asking just because of the famous android
latency issue.
It will be nice to see the Jambar use
Csound. We'll be working on getting plugins to work on Android, so
it might be possible to get the fluid opcodes into it. (off the top
of my head, the soundfont ones are there as built-in, so they can be
used)

The sample tracks you see at http://acousticorchard.com/microsynth/market were
made with my "first" version of Monodot (1 osc, delays and
filter/LFO). It was made on an HTC glacier phone recorded
using a Zoom R8 portable recorder. The only other sound that
is not my Monodot app are the drum tracks that come with the Zoom
R8. >
My Jambar product is my first app and is sample based.
It is an attempt at a phrase loop type product. I used
Android's SoundPool. SoundPool is a bit buggy and I was
porting it to AudioTrack. I had an experimental version
running Csoundlib and will probably move it to csoundlib at some
point. >

Definitely. By the way, how did you make the example

I saw the JamBar, what is that based on for
