Abstract
To produce a three dimensional sound, an original sound recording is duplicated and the original of its duplicate are then recorded with a time delay in the range of 25 ms to 990 ms, preferably 100 to 500 ms. The resulting first echo recording is duplicated to produce a second echo recording and these are recorded with another time delay, preferably less than the first but within the aforementioned range to yield a fifth tape which has a so-called third echo imparting to the sound a three-dimensionality which cannot be achieved by conventional reverberation and echo methods.
Claims16
A method of generating three-dimensional sound comprising the steps of:
- (a) binaurally recording an initial sound to form a first recording;
- (b) duplicating said first recording to form a first duplicate;
- (c) playing said first recording and said first duplicate with a first time delay Δ2 therebetween with respective players each having right and left channel outputs;
- (d) combining one of the channel outputs of each of said players in a respective Y connector for each of a right and a left channel input of a recorder to form a second recording;
- (e) duplicating said second recording to form a second duplicate;
- (f) playing said second recording and said second duplicate with a second time delay Δ2 therebetween with respective players each having right and left channel outputs;
- and
- (g) combining one of the channel outputs of each of said players in step (f) in a respective Y connector for each of a right and a left channel input of a recorder to form a further recording carrying a three-dimensional sound signal.
