About This Application Note

The PlayBeat Reusable Subsystem Application Note contains a brief description and tuning instructions for DSP Concepts’ PlayBeat dynamic excitation Reusable Subsystem.

PlayBeat – Dynamic Excitation Reusable Subsystem

PlayBeat is DSP Concepts’ proprietary dynamic excitation algorithm, available as a Reusable Subsystem in AWE Designer.

PlayBeat emphasizes signal onsets in low frequencies and dynamically enhances the low-frequency beat in audio streaming content. It works with mono and stereo audio at all sampling frequencies and block sizes.

Example

Figure 1 shows an example layout demonstrating the PlayBeat Reusable Subsystem. This example layout is designed to run in Native Mode with a file input; audio signals must be assigned to appropriate channels when running the layout on a target device.

In the example, a gain control module (specifically, the MainVolume ScalerV2 module) is placed after the PlayBeat Reusable Subsystem.

Tuning

The PlayBeat Reusable Subsystem includes an inspector that lets users tune the strength of dynamic excitation (i.e., low-frequency beat emphasis) 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 0.4 as a default. A stronger Effect setting may cause low-frequency clipping distortion.
