Sound delay on Android

Artiom

Hi!
When I play one small wav sound effect I get the ~0.2-0.3 sound delay on my HTC One.
Sure I preload sound first then play when I need it.
What's the fix for this?

Artiom

I did some tests and can tell that playing small mp3 has much lower delay.
I saw a lot of topics about that problem starting from 2012. I'm wondering why this is not fixed yet..

SinisterSoft

No, I think there will be a new sound system in Gideros 2 that will solve this problem. Hopefully...

Artiom

@SinisterSoft,
So we can't release games until Gideros 2 is out?

SinisterSoft

There is something wrong with render to target that makes a Samsung Galaxy Fame crash. Hopefully this is fixed in the next build or 2.0 - so I'm waiting too.

Artiom

@SinisterSoft,
Yes, I reported that too. There are several bugs with render target..

SinisterSoft

I even set the scale to no scale and back again after I've allocated the render size - still a crash on that particular phone.

Seems the phone is pretty popular too as it was a giveaway phone on a cheap Virgin tariff.

Artiom

I had a crash using Widget Candy's list (it uses RenderTarget). I have to recreate list each time it's updated to avoid this.

Artiom

Nice.. Seems Gideros can't handle playing small mp3s frequently.
Just got the crash after playing my game 5 min:

Who knows good sound library?

ar2rsawseen

@Artiom for now please use wav for small file playback and mp3 for continues background music playback

Artiom

@ar2rsawseen,
But what to do with delay? I can't release game when user presses a button and hears sound in a half second.

SinisterSoft

It's not half a second - but it is a few frames. Hopefully the sound system will be changed for v2.

Artiom

@SinisterSoft,
Few frames is about ~32ms, it can't be noticeable. I exactly hear long delay.

ar2rsawseen

@Artiom even with wav?
Because I don't see anything so noticeable even on my very old Android device:

SinisterSoft

@ar2rsawseen - I've noticed slight (noticable) delays (a lag, but not 30 frames worth - maybe between 8 and 16 on a Galaxy S3) and I clip the sound right to the beginning.

Maybe the sound has to be processed before being played? What sound format are you using 16-bit/8-bit/frequency/mono/stereo etc.. Which is fastest to play?

ar2rsawseen

all the sound effects are done in wav, 16bit, sample rate 44.1kHz

SinisterSoft

I'm using 22k or less, I wonder if there is some processing done to upscale them?

Artiom

@SinisterSoft, @ar2rsawseen,
Seems that problem is in my HTC One :O
Tested on some older devices and it works like a charm almost without delay.
