Audio Datatypes playing question.

Hello.

when we play a datatype sound using the :
IIntuition->IDoMethod( MySoundPTR, DTM_TRIGGER, NULL, STM_PLAY, NULL );

Is there a way to:
1. Change the sound playback volume ?
2. Change the left/right pan values ?
3. Make a sound to loop?
4. Get informations on actual values for 1., 2. and 3. ?

I've checked the STM_xxxx flags and none of them answered me.

If someone know.
Please help.

Sincèrely

STM_ are methods. You need to look for attributes which are called STA_.

Hello Thomas,
I've found attributes called : SDTA_xxx
I think they're the correct ones ;)

Thank you for your answer.

Kindest Regards,

Here are some examples how to play sounds with datatypes:

Sorry for the off topic.

@Thomas

Thomas, did you ever considered joining the official wiki effort for documenting AmigaOS (see AmigaOS wiki)? Your knowledge, your experience and your almost endless samples may really help improving our OS documentation. All those years each time I saw you giving advice or sample it was exactly answering the problem.

@abalaban

...I would even consider to state that Thomas actually *IS* the AmigaOS-Wiki!

@freddix

I wrote a simple sample playing engine using AHI device interface and PCM WAV files for a Missile Command clone. You can find the source code for it here (check audio_ahi.c and audio_io.c files):

Alternatively you could just use SDL_mixer which has support for more sample formats and far more advanced API.

@Thomas :
Thank you.
Your sample show a more friendly way to use Datatypes :p

@Salass00:
Thank you for your sample too :)
Really interesting sample for AHI use.
I will investigate your sample when I'll add 3D sound :)

Kindest Regards,
