Abstract
An audio signal encoding method is provided comprising: receiving first and second audio signal frames; processing a second portion of the first audio signal frame and a first portion of the second audio signal frame using an orthogonal transformation to determine in part a first intermediate encoding result; and processing the first intermediate encoding result using an orthogonal transformation to determine a set of spectral coefficients that corresponds to at least a portion of the first audio signal frame.
Claims9
A method for encoding an audio signal, comprising:
- applying a first transformation to a first portion of a current frame to obtain a first transformation result prior to receiving a subsequent frame;
- and
- encoding a preceding frame using the first transformation result;
- wherein the preceding frame, the current frame, and the subsequent frame are consecutive frames of the audio signal.
