celp_codec ========== This is a simple CELP voice codec implementation. http://en.wikipedia.org/wiki/Code-excited_linear_prediction Features -------- * Encoding and decoding from multiple WAV and AIFF formats. * Support file or stdin/stdout * Real time processing, encode and decode from streams. * Configurable - LPC order - Frame length - Number of subframes - Adaptive codebook size - Multiple frame windows ('hanning', 'boxcar', etc) - Weighting coefficients Dependencies ------------ * numpy * scipy * ctlibsnd (áython libsndfile wrapper) https://bitbucket.org/san/ctlibsnd Future improvements ------------------- * Implement fixed codebooks of different sizes * Support more sample rates (currently only 8 kHz) * Preprocesing filter (high pass, and equalization) * Convert LPC (linear prediction coefs) to LSP (linear spectral pairs) - Quantize LSP - Convert LSP to LPC
