TI introduces integrated audio codec for mobile devices

Audio and voice samples can be received, mixed and processed seamlessly within the codec. The inclusion of TI audio and voice algorithms, as well as third party algorithms, available on the codec and as additional licenses, benefits designers creating multi-purpose and high-definition audio designs for mobile devices.

Among the device’s key benefits are: third-generation miniDSP technology that enables wideband noise and echo cancellation at up to 16 kHz to create clear, high-definition voice quality for circuit-switched or VoIP calls, including video conferencing applications and SRS WOW HD is included as a standard feature at no additional cost to customers. This improves audio playback quality and enables faster processing by offloading the duties of the host processor to the codec. Designers can also evaluate other certified pre-integrated SRS solutions such as TruMedia, CircleSurround Headphone and TruSurround HD, which are available commercially through direct licensing agreements with SRS Labs, Inc.

In addition the three asynchronous audio buses plus asynchronous sampling rate conversion (ASRC) allows designers to connect to multiple audio sources and mix multiple sample rates and intelligent speaker protection algorithms control voice coil temperature and diaphragm excursion to enable maximum possible loudness without damaging the speaker.
