digital reverberation unit

Artificial reverberation is an extremely useful sound effect which can be used to compensate for the small dimensions of most listening rooms by using a delay line to increase the proportion of `reflected` sound heard by the listener. The resultant passage of music is therefore lent that extra dimension of `spaciousness` or `body` which is normally only captured during a concert-hall performance. Of the many different methods of constructing a delay unit, this article describes the most advanced, namely a digital delay line.
