Playing sounds with ASND and AESND

Hi, i'm trying to play wav files, I have managed to decode a wav file and stored in a buffer with this lib
[pastebin.com]
[pastebin.com]

But when I try to play with

ASND_SetVoice(voice, VOICE_STEREO_16BIT, pFmt.sample_rate,0, buf, sizeof(buf), 255, 255, NULL);
ASND_PauseVoice(voice, 0);

It doesnt return me any error, but i dont hear nothing. What am I doing wrong?

It would be better to try to use AESND?

AESND_PlayVoice(AESNDPB *pb,u32 format,const void *buffer,u32 len,u32 freq,u32 delay,bool looped);

Thanks

You made sure to ASND_Init() right?

Yes i do after WPAD_Init();

"buf" is a pointer, this means "sizeof(buf)" will return the size of the pointer, which is usually 4 bytes (size of a memory address), not the size of the buffer in memory .

This also means only one 16-bit stereo sample would be played, and you would definitively not hear anything.

try using

pFmt.sample_channel * pFmt.sample_count * pFmt.sample_byte

as the size parameter

Hi, i do this but it doesnt hear, the wav file is PCM 16bit stereo

Is it in Big Endian?

mm, no but the wavplayer librery convert it, or not?

inline u32 le32(u32 i) {
        return ((i & 0xFF) << 24) | ((i & 0xFF00) << 8) | ((i & 0xFF0000) >> 8) | ((i & 0xFF000000) >> 24);
}
 
inline u16 le16(u16 i) {
        return ((i & 0xFF) << 8) | ((i & 0xFF00) >> 8);
}

Didn't you ask the exact same question here: [devkitpro.org]

As EkE said on devkitPro:

At a first glance, that seems normal, pFmt.start and pFmt.end are never initialized and they would hold zero by default, hence the result is 0.
You probably need to initialize these fields to -1 before calling LoadPCMWav, in order to get the whole sound length.

I'd advise you to first learn how to use the functions you are calling, seems like you copy-pasted some code from another application but without really understanding what it does and how it works.

but i fix it irrlich

int wavPlayer(const char* file) {	
	pFmt.start=-1;
	pFmt.end=-1;
   void *buf = LoadPCMWav(file, &pFmt);
   s32 voice = ASND_GetFirstUnusedVoice();
   if (buf) {
      if (ASND_SetVoice(voice, VOICE_STEREO_16BIT, pFmt.sample_rate,0, buf, pFmt.sample_channel * pFmt.sample_count * pFmt.sample_byte, 255, 255, NULL) == SND_OK) {
		ASND_PauseVoice(voice, 0);
	  } else {
		return 0;
	  }
   } else {
      return 0;
   }
   return 1;
}

But it doesnt hear

See if they help you here, and you can post the luafwii 1.0

i might be able to help with ASND... i've gotten that to work for me easy.

Haven't messed with AESND yet... (just finally got around to updating libogc last night)

You have IRC :D?

Thanks mdbrid, yes i have an IRC, I send you a MP with the URL

Adrian6184 if i solved Wav problem and a little problem with usbkeyboard i release inmediatly XD

i'm on #wiihelp on efnet... should be on in a few hours.

Thanks mdbrim, i fixed and released a new version, thanks

no problem man, my pleasure!
