About This Application Note

The PlayVoice Reusable Subsystem Application Note contains a brief description and tuning instructions for DSP Concepts’ PlayVoice dialog enhancement Reusable Subsystem.

PlayVoice – Dialog Enhancement Reusable Subsystem

PlayVoice is DSP Concepts’ proprietary dialog enhancement algorithm. It is available as a Reusable Subsystem in AWE Designer.

Ncontent typically positioned in audiostreams. PlayVoice identifies the signals in the center of stereo streaming content and emphasize them. PlayVoice works for stereo audio content with all sampling frequencies and block sizes.

Example

Figure 1 shows an example layout demonstrating the PlayVoice 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.

Tuning

The PlayVoice Reusable Subsystem includes an inspector which allows users to tune the effectiveness of dialog enhancement using an Effect knob. The Effect knob ranges from 0 to 1, with 0 yielding no effect and 1 yielding the strongest effect. DSP Concepts recommends using an Effect level of 0.5 as a default.
