ATRAC is 292kbit/sec, giving “CD like” audio fidelity. MPEG Layer 1 (i.e. PASC) gives transparent CD fidelity audio at 384kbit/sec, Layer 2 (i.e. Musicam) and Layer 3 give “CD like” fidelity at 224kbit/sec and 128kbit/s respectively. A user has compared ATRAC and MPEG Layer 3 and rates ATRAC far better. VQF has a system offering 18:1 compression, pitched as something of an alternative to MP3.
