About This Application Note
The PlayWide Reusable Subsystem Application Note contains a brief description and tuning instructions for DSP Concepts’ PlayWide stereo expansion Reusable Subsystem.
PlayWide –Stereo Expansion Reusable Subsystem
PlayWide is DSP Concepts’ proprietary stereo expansion algorithm. It is available as a Reusable Subsystem in AWE Designer.
PlayWide emphasizes the differences between left and right channel signals in the mid- and high- frequency ranges to increase the perceived width of a stereo playback system’s soundstage.
PlayWide works for stereo audio streams with all sampling rates and block sizes.
Figure 1 shows an example layout demonstrating the PlayWide 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 a target device.
The PlayWide Reusable Subsystem includes an inspector which allows users to tune the strength of the stereo expansion effect. 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 0.3 as a default.
