FLAC Multichannel Decoder
FLAC stands for Free Lossless Audio Codec, a non-proprietary lossless audio format. FLAC supports all sampling rates,commonly used sample rates are 8/16/22.05/24/32/44.1/48/96 kHz. FLAC imposes a minimum block size of 16 samples, and a maximum block size of 65535 samples. FLAC supports from 4 to 32 bits per sample. This range covers the optimal size for all of the audio data FLAC supports.

Case studies

Developing an Asynchronous Sample Rate Converter

Designing an Asynchronous Sample Rate converter that offers high THD and low ripple across a range of frequencies is no mean achievement. We not only designed the ASRC but implemented it with low MHz on a fixed point processor.

Video codecs on a multi-core highly-parallel custom core

We worked with SiliconHive (now part of Intel) to develop High Definition video codecs that are designed to run optimally on a multi-core environment. Our contribution also included efficient coding for a VLIW core and algorithmic innovations to address memory bandwidth constraints.
