SRS Dialog Clarity Processor
■GENERAL DESCRIPTION
■PACKAGE OUTLINE
The NJM2194 is a SRS Dialog Clarity Processor to
enhance the dialog in a stereo signal by extracting the dialog
information, augmenting it using a proprietary dialog clarity
algorithm, and mixing it back in to the final stereo audio
signal. When this stereo audio is played, the speech dialog
becomes much easier to clearly hear while leaving the
ambient information unchanged and the volume at a normal,
more comfortable level for others in the room at the time.
The NJM2194 is suitable for audio applications such as TV,
DVD and others.
