An audio server, or sound server, is software that manages the use of audio devices. Such software typically runs in the background. PulseAudio is the standard audio server for desktop audio on Linux, while JACK is the standard audio server for professional audio on Linux.

Phase is the offset of two waveforms expressed in degrees, where 360 degrees corresponds to a delay of one cycle. Waveforms that are 180 degrees out of phase will cancel each other out to complete silence.
Phase problems can occur when two similar sound sources are out of alignment with each other. This causes the drop out of certain frequencies, which can make recordings sound thin if not dealt with.
