Encodes the linear samples using 8-bit μ-law format and stores them in a vector.
Searches for the adaptive codebook index and the lag, and computes the adaptive vector.
The scale application procedure is necessary for MPEG-2, 4 GA AAC decoder to restore the original spectral values from a set of the inversely quantized spectral coefficients. The whole spectrum is divided into a set of scale factor bands. Since the widths differ from band to band, the band positions are defined by the offset vector.
Initializes predictor state.
Encodes an array of values into destination bitstream in AAC format and advances bitstream pointer.
DEPRECATED. Computes inverse modified discrete cosine transform (MDCT), windowing and overlapping of signals.
DEPRECATED. Estimates stationarity of signal by calculating deviation of spectrum audio signal.
