Magnetic tape or film stores audio information via metal particles applied to one side of the tape or film. A record head applies a magnetic flux to those particles, which then orient themselves to represent the audio information. A playback head reads the magnetic flux stored on the tape to
7.1 Multi-channel Audio
7.1 refers to multi-channel audio intended to be monitored through eight channels: seven full frequency range (20Hz to 20KHz) channels and one frequency limited (below 120Hz) channel for the LFE (Low Frequency Effects), or Subwoofer track. 7.1 multi-channel audio has several theoretical channel
An over-processed track suffers from what audio engineers might consider to be too much of a good thing. Any process designed to improve, repair, enhance, or otherwise advance the quality of an audio track can, if used in excess, have the reverse effect and start to diminish its overall quality.
