- Abstract
- The use of an additional microphone to provide an anticipation signal to operate noise-reduction circuits is described, the anticipation microphone being placed ahead of the signal microphone by sufficient distance so that the noise-reduction element in a modulator is fully opened to permit recording of the maximum signal amplitude. In rerecording a special hill-and-dale record is made of the last rehearsal. This record is then played back during the take, the output being fed to the noise-reduction circuit and anticipation being accomplished by moving the needle ahead on the disk by an appropriate distance.
