Audio and voice processing algorithms enable better user experience in mobile phones, tablets and mobile computing devices
Texas Instruments has introduced the industry's most highly integrated audio codec with embedded miniDSP cores, providing echo and noise cancellation at wideband voice sampling rates up to 16 kHz. The TLV320AIC3262 integrates five amplifiers and two miniDSP cores, and gives designers the ability to interface to up to three devices simultaneously, such as application, Bluetooth and baseband processors. 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. For more information and to order samples, visit www.ti.com/tlv320aic3262-preu. Key features and benefits of the TLV320AIC3262:
- Third-generation miniDSP technology 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.
- SRS WOW HD™, included as a standard feature at no additional cost to customers, 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 TruMediaTM, CircleSurround HeadphoneTM and TruSurround HDTM, which are available commercially through direct licensing agreements with SRS Labs, Inc.
- Three asynchronous audio buses plus asynchronous sampling rate conversion (ASRC) allows designers to connect to multiple audio sources and mix multiple sample rates.
- Intelligent speaker protection algorithms control voice coil temperature and diaphragm excursion to enable maximum possible loudness without damaging the speaker.
