encoder block diagram
...ses 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 psychoacoustic model come from MDCT
above or an extra MDCT is performed (would that make sense at all ?)
- the floor data are then subtracted (amplitu...
