PlayPack

Slimmer product designs and shrinking space for components means product makers need to look beyond loudspeaker size for sound quality. PlayPack provides the essential elements to enhance, enrich, and augment output with stereo imaging, dynamic control, psychoacoustic bass, and dialog boost.

DSP Designs - PlayPack

Benefits for Product Managers

  • Fully tunable
  • Compensates for loudspeaker driver size and position
     

Benefits for Audio Engineers

  • Easily integrates with TalkTo and TalkTogether technologies
  • MIPS and memory optimized for small form factor products
  • Easily achieve target acoustical output with varying input levels

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
response

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 steaming 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
