WM0011
General Purpose Low-Power Audio DSP
DESCRIPTION
WM0011 Audio DSP provides Wolfson HD audio quality,
with a power-budget targeted at handheld battery-powered
audio devices.
WM0011 combines the advanced Tensilica HiFi EP™ audio
DSP with an I/O and peripheral set optimized for flexible
integration into smartphones, tablets and other portable
consumer electronics devices. WM0011 is ideal for
extremely power-efficient implementations of advanced
voice enhancement, telephony noise reduction, voice and
music CODECs and general audio enhancement.
A very wide range of audio CODECs, voice CODECs and
third-party algorithms from such companies as Waves
Audio, SRS Labs and Dolby are available, providing a rich
portfolio of audio-processing options that can be integrated
into a device with no additional software development.
WM0011 comes in a space-saving 3x3mm 49-ball W-CSP
package with 0.4mm pitch.
