A Basic perceptial coder for audio compression.
This coder uses several techniques to optimizes its audio compression, including:
- dynamic quantization
- transient detection
- perceptual model
To code an audio file, call mdct_coder(ifile,quantmode), where:
- ifile is input *.wav file
- quant_mode is:
- 0: no quantization
- 1: quantize Thr and MDCT coefs
