[comp.sources.wanted] Wanted: C program for 32 kbit/sec ADPCM standard; CCITT G.721

per@derek.Philips.Com (Paul E. Rutter) (01/13/90)

Subject says it all:  I would like a public domain C program that implements
CCITT Recommendation G.721.

G.721 is an Adaptive Differential Pulse Code Modulation algorithm that
transcodes 64 kbits/sec PCM signals (telephone quality) into 32 kbits/sec.

thanx.
