Audio Codecs & Algorithms

AUDIO COMMUNICATION CODER (ACC)

Audio Communication Coder (ACC) is a new source/perceptual audio compression technology created at ATC Labs featuring low coding delay (less than 50 ms) and moderate system complexity, and benefits from other innovative design aspects making it suitable to satisfy.

The increased consumer expectation of higher voice/audio quality and new functionalities in mobile communication.

TESLAPRO

TeslaPro is a broadcast quality audio codec comprising of advanced audio and speech compression tools. It is being offered as an integrated codec operating in the range of 3-128 kbps. TeslaPro utilizes in-house expertise in auditory perception modeling and signal processing for its perceptually enhanced audio coding capabilities.

TeslaPro uses state-of-the-art coding techniques to encode complete bandwidth of the audio signal. With efficient coding techniques Teslapro achieves cd-quality stereo at bit rates as low as 40-48Kbps.

Audio Bandwidth Extension Toolkit ( ABET )

Audio Bandwidth Extension Toolkit ( ABET ) - readymade stand alone toolkit to enhance capability of every low bandwidth audio encoder. The extended bandwidth gives that extra dimension to your audio which is usually lost in the dint of bandwidth constrains imposed on the audio coder. Be it either a sports commentary or a rock concert, to simply put it, the bigger the bandwidth the better the sound.

IMMERSIVE SOUND FIELD RENDITION (ISR)

Immersive Soundfield Rendition (ISR) system is an in-house low bit rate multi-channel audio codec ( 5.1-channel ). The high quality multi-channel audio compression tool is engineered with state-of-the-art patent pending algorithm namely, Multi Band Temporal Amplitude Coding (MBTAC). ISR emphasizes the accurate reproduction of multi band temporal envelope of Multichannel data.

IMMERSIVE SOUND FIELD RENDITION (ISR)

The SoundEngine SDK provides an easy to deploy codec suite consisting of many high quality implementations of popular codecs in addition to proprietary ones. The SDK supports various codecs for playback and recording and is available either bundled in the SDK or may be licensed separately. Highly optimized floating, fixed and DSP implementations for ARM and Blackfin platforms are available.
