ATC Labs is an audio and multimedia development company founded in New Jersey,U.S.A in the year 2004. The company was founded by a group of Bell Labs alumnus including, Dr. Deepen Sinha, Dr. Anibal Ferreira and Mr.Andre Partyka.

ATC Labs' audio division recently introduced a new suite of codec products, marketed under the name TeslaPro. Currently, it provides product upgrade services to Sirius satellite radio for its PAC4 codec, as well as the statistical multiplexing technology, and maintains collaborative agreements with other research organizations. On the services side, ATC Labs offers support for customer's in-house audio and/or multimedia technology development projects, out-sourced technology development, subjective audio quality evaluation, and assistance in optimizing the sound quality performance of audio broadcast studios.

Apart from its Design, Test and Development center in U.S the company has its Software and Technology development center in Noida,India. The Noida center is being operated through its wholly owned subsidiary, Audio Technologies and Codecs (India) Private Limited.

[edit] Audio Technology

[edit] TeslaPro

TeslaPro comprises of audio and speech compression codec technologies and may be used individually or as an integrated codec operating in the range of 4-96kbps. TeslaPro utilizes enhanced auditory perception modeling and signal processing techniques.

[edit] Audio Communication Coder (ACC)

The ACC codec is designed to offer extremely low end-to-end delay by minimizing the size of the transform, look-ahead and bit-stream buffers.

[edit] Audio Bandwidth Extension Toolkit (ABET)

ABET is a stand-alone toolkit which can be integrated with any low bandwidth audio codec scheme to improve its audio bandwidth capability. ABET is based on ATC Labs' two patent pending algorithms namely, Accurate Spectral Replacemet(ASR) and Fractal Self Similarity Model(FSSM). ABET also incorporates a third essential tool, Multi Band Temporal Audio Coding(MBTAC).

[edit] Immersive Soundfield Rendition System (ISR)

Immersive Soundfield Rendition (ISR) system is a tool to code 5.1 channel audio with very low bit overhead. A conventional stereo encoder can be upgraded to a multichannel encoder utilizing an ISR bitstream as overhead. The ISR system uses Multi Band Temporal Audio Coding(MBTAC). ISR can work on 2 to 12 Kbps bit overhead range. Key features of ISR system are:

  • Blind Upmixing (2-to-5 channel)
  • Acoustic Diversity Creation
  • Phase Compensated Downmix (5-to-2 Channel)

[edit] Audio Noise Reduction Toolkit

Noise Reduction Toolkit is a psychoacoustic based noise removal technique to restore an audio from a noisy audio/recording. This technology is based on an ingenious patent pending algorithm developed at ATC Labs.

[edit] Video Technology

The work on Video Technology is in the Research and Development phase. We are planning to launch our video products in a few months time. Perceptual based quality optimization is the prime distinctive feature of all our products.

[edit] Multi-format Video Codec Platform

The Multi-format Video Codec Platform is a universal platform offering an optimized Encoder-Decoder compilation of all elite video formats, on windows platform. This complete Encoder-Decoder suite encodes all popular formats including H.264, H.263+, MPEG-2 etc… and is capable of playing any of the above mentioned encoded formats.

[edit] Multi-format Video Codec Platform with Transcoding Capabilities

This product addresses the key problem of the future of video entertainment market to handle multiple video formats on a single device. Multi-format Video Codec Platform with Transcoding facility provides a seamless solution by ‘real time’ inter conversion of various formats including H.264, H.263+, MPEG-2 etc… on windows platform. Low complexity and ‘on the fly’ format conversion are the salient features of this transcoding tool.
