3-bit ADPCM playback - Meenakshi Matai - Oct 12 12:27:00 2004



Hello,

I am looking for a plugin that can playback G.723 3-bit ADPCM encoded 
data. I know that the standard .wav file header can take the following 
information:

*Code* 	*Description*
0 (0x0000) 	Unknown
1 (0x0001) 	PCM/uncompressed
2 (0x0002) 	Microsoft ADPCM
6 (0x0006) 	ITU G.711 a-law
7 (0x0007) 	ITU G.711 µ-law
17 (0x0011) 	IMA ADPCM
20 (0x0014) 	ITU G.723 ADPCM (Yamaha)
49 (0x0031) 	GSM 6.10
64 (0x0040) 	ITU G.721 ADPCM
80 (0x0050) 	MPEG
65,536 (0xFFFF) 	Experimental
	It looks like whatever plug-in I install, the WAVE form Registration 
Number (hex): 0x0014 is what I would need. Could you please point me 
towards any information on this.

Thanks,
Meenakshi.
