Hello,
after unsuccessful attempt to get Android Studio work with csound 6.05, I am
working in eclipse IDE.
I have noticed a difference in a sound being played from two applications on
my Nexus 7:
1) the CSDPlayer (Csound6)
2) my custom app.

The case is that my application generates a 'distorted' metronome sound
while the CSDPlayer plays it smooth. 
The .csd file used for both apps is the same. A simple metronome:


-odac -d -m3 -b1024 -B1024


sr = 44100
kr  = 4410
0dbfs = 1
nchnls = 2

instr 1
; variables passed from the java code:
ksec chnget "sec"
kmin chnget "min"
khour chnget "hour"
ktempo chnget "tempo"

gisine    ftgen    0,0,4096,10,1
;kmetro    metro    ktempo/30 OFFLINE:
kmetro    metro    2
schedkwhen    kmetro,0,0,2,0,0.03
endin

instr    2
acps    transeg    2000,p3,-15,200
aamp    transeg    0.5,p3,-6,0
asig    poscil    aamp,acps,gisine
outs    asig,asig
endin 



i 1 0 200

 

It is not the case of SW and HW buffers legth.
I am using BaseCsoundActivity class as a backbone in my app.
My csound initialization:
String csd = getResourceFileAsString(R.raw.score);
File f = createTempFile(csd);
csoundObj.startCsound(f);

In my manifest file I use
" "

How should I configure my app to make it play the sound properly?
And there goes my another question - would you post a documentation of java
functions operating on csound object?
I have not found any sufficient documentation on that.

Regards,
Michał Dobrzański

Buffer sizes: try -b 256 -B 1024. What you describe sounds like dropouts.

As a sidenote, I've been research Csound with Android Studio yesterday
and today.  I've just gotten CsoundAndroid to build as a library
module project and generate an AAR file.  I'm experimenting now to see
about making sure that works from the Examples project.

I still have to investigate a number of things, but at least it's
moving forward.  I hope to have something to test with in the next
couple of days.

Unfortunately, it did not help. I guess I should configure csound object in
my app somehow, but I have no clue where and what should I check.
