SRS WOW HD Audio Processor IC
OVERVIEW
The AP8302 is a WOW HD audio enhancement processor
based on SRS Labs’ award-winning WOW technology.
WOW delivers
a broadened stereo field, improved
dynamics and increased bass performance over stereo
headphones or a wide range of speaker sizes. WOW HD
goes a step beyond WOW by delivering a new purity to
sound with cleaner, livelier audio quality (definition),
advanced bass enhancement for fatter low frequency bass
(TruBass) and incredibly innovative “center” control to
place center information in the stereo mix in the forefront or
toward the back, in a delicate balance with the 3D stereo
width control (SRS 3D).
AP8302 operates under hardware mode or software mode in which the audio enhancement features are
programmable through I2C bus, making it suitable for wide range of applications with or without external
MCU. Extended flexibility in software mode operation allows AP8302 to load preset configuration of
WOW HD stored in external EEPROM for optimal audio effect. Enhanced selectable TruBass filter setting
by pin settings for speaker with typical resonant frequency between 40Hz and 400Hz minimizing external
components. Apart from the integrated TruBass audio enhancement, separate subwoofer output is also
available to support external connection to a subwoofer for dedicated bass reproduction. The built-in
input volume control prevents signal clipping during audio enhancement while incorporating output
volume control further reducing the total number of external components.
