AlsaPlayer for Linux is a new kind of player that effectively runs pulse-code modulation or .PCM files. The player uses multithreading pretty heavily and was written specifically for giving some good exercise to the new Advanced Linux Sound Architecture (ALSA) driver and the library system. If you look closely, you’ll observe that AlsaPlayer has some highly interesting features that can be found only in the UNIX-based or Linux-based players. The main goal of the people who created AlsaPlayer for Linux was to develop a completely pluggable framework that could playback every type of media file, with majority of focus on the PCM audio data.
