...o any allowed size - selected window size depends on bitrate MDCT - transforms audio data to frequency domain PSYCHOACOUSTIC MODEL - Vorbis uses its own psychoacoustic model - FFT for tonal analys and MDCT for noise analysis Floor - a psychoacoustic floor is created from the data, given from the psychacoustic model - the floor is a spectral envelope and represents a low resolution model of the audio spectrum - floor type 0 uses LSP and floortyp 1 a linear interpolation algorithm to compute the floor curve ? currently only floor type 1 is used ? don't know whether the MDCT input for the psychoacousti...
