ABSTRACT:
A reverberation sound producing apparatus is disclosed which has an input terminal supplied with audio frequency signals, filters for dividing the audio frequency signals applied to the input terminal into a plurality of frequency bands, delay lines for delaying output signals from the filters by different intervals of time, and circuits for composing output signals from the delay lines and delivering delayed audio frequency signals to an output terminal. Lower frequencies are delayed longer, causing a concert hall effect.
