MPEG layer 1/2/3 audio player Mpg123 is a fast and portable MPEG audio player for Unix. It supports MPEG 1.0/2.0 layers 1, 2 and 3 (those famous "mp3" files). For full CD quality playback (44 kHz, 16 bit, stereo) a Pentium, SPARCstation10, DEC Alpha or similar CPU is required. Mono and/or reduced quality playback (22 kHz or 11 kHz) is even possible on 486 CPUs. This package contains output plugins for several audio systems, including OSS/Lite, the Advanced Linux Sound Architecture (ALSA) on Linux systems, the Enlightened Sound Daemon (esound), the Network Audio System (NAS), and others.
