A progressive to lossless embedded audio coder (PLEAC) with reversible modulated lapped transform
A progressive to lossless embedded audio coder (PLEAC) has been proposed. PLEAC is based purely on a reversible transform, which is designed to mimic the non-reversible transform in a normal psychoacoustic audio coder as much as possible. Coupled with a high performance embedded entropy codec, this empowers PLEAC with both lossless capability and fine granular scalability. The PLEAC encoder generates a bitstream that if fully decoded, completely recovers the original audio waveform without loss. Moreover, it is possible to scale this bitstream in a very large bitrate range, with granularity down to a single byte. Extensive experimental results support the superior lossless performance and bitstream scalability of the PLEAC coder.
