(57) Abstract :
A module (402) for binary coding of a signal envelope, comprising coding module (502) for coding a variable length first mode.
According to the invention, the coding module for coding the first mode incorporates an envelope saturation detector and said coding
module (402) further includes a second coding module (503) for coding a second mode in parallel with the coding module (502) for
coding the first mode and a mode selector (504 adapted to select one of the two coding modes as a function of a code length criterion
and of the result from the envelope saturation detector. Application to transform coding of audio-frequency signals.
