PlayVolumeControl Reusable Subsystem
About This Application Note
The PlayVolumeControl Reusable Subsystem Application Note contains a brief description and tuning instructions for DSP Concepts’ PlayVolumeControl perception-based volume control Reusable Subsystem.
PlayVolumeControl – Perception-Based Volume Control Reusable Subsystem
PlayVolumeControl is DSP Concepts’ proprietary perception-based volume control algorithm. It is available as a Reusable Subsystem in AWE Designer.
The PlayVolumeControl dynamically applies additional boosts to low and high frequencies based on look-up tables to compensate for differences of perceptual sensitivity in those frequency ranges as a function of the overall sound level.
PlayVolumeControl works for all sampling frequencies, block sizes, and numbers of channels.
Example
Figure 1 shows an example layout demonstrating the PlayVolumeControl Reusable Subsystem. This example layout is designed to run in Native Mode with a file input; audio signals must be assigned to appropriate channels for running the layout on a target device.
