4.8 Kbps CELP Coder 􀂄 Each frame is divided into 4 subframes. In each subframe, the codebook contains 512 codevectors. 􀂄 The gain is quantized using 5 bits per subframe. 􀂄 The LSP parameters are quantized using 34 bits s

Lpc Vocoder is used to decode the audio files. Where we can test the pitch, bits and formants of the audio files.
