We present a simple lossless audio codec, composed of an integer-reversible modulated
lapped transform (MLT) followed by a backward-adaptive run-length/Golomb-Rice (RLGR)
encoder. Its compression performance matches those of state-of-the-art predictive codecs,
and it has the advantage that its compressed bitstream contains frequency-domain data that
can be used for applications such as search, identification, and visualization. Its
compression gain can be improved through a novel data model based on cross-block …
