PlayWide Stereo Imaging

Widens the sound field of stereo playback systems beyond the physical limitations of built-in loudspeakers

• Relies on the stereo cues present in the content
• Creates expanded and more immersive output

PlayBass Bass Enhancement

Extends the perceived bass response of loudspeakers using psychoacoustic science

• Adds high frequency harmonics based on low frequency fundamentals
• Prevents potential low frequency clipping without altering the frequency

PlayVoice Dialog Boost

Improves intelligibility of speech in mixed content

• Creates a virtual dialog center channel from stereo input
• Emphasizes voice band range (500 Hz – 5 kHz) while attenuating non-voice band signals

PlayLevel Level Smoothing

Automatic level matching between sources and streaming apps.
Controls the dynamic range of content in real-time:

• Minimizes volume changes between programs
• Maintains output at a target dBFS RMS level despite varying input levels
• Avoids amplification during silence segments
