Speech Codec for Japanese Digital Cellular Phone

• Archive(vselp.tar.gz : 42KB)
• Document (in Japanese)  
• Satisfying RCR STD-27B
• Including error control encoding/decoding (Hard Viterbi)
• Supporting signed 16 bit, 8000 kHz sampling, and single channel raw audio format only

 

remember: some Motorola ASTRO Systems use VSELP and are un-/or encrypted.

No Radioscanner today covers VSELP Systems...
