LB, aka Low Bitrate is a audio format optimized for low bitrates (44kHz, stereo at the default level: ~20 kbps), and can produce quite good quality at this bitrate. The player and packer were both created by Dmitry Shmunk. The player & packer are both for DOS, but it has a Windows player (not packer).

Identification
