- EAS Enhanced Audio Surround
EAS refers to a group of audio processing modules, which cater to Enhanced Surround Sound in Home Theater environment. There are three basic building blocks in EAS. They are Mono to Stereo block, Stereo to Multi-channel block (4.1/5.1/6.1/7.1) and Reverberation block. It has been developed and ported on to SHARC LX3 platform by Jasmin Infotech. It can be provided as a source file or as an object library and can be customized to user’s requirements.
- ASRC Asynchronous Sample Rate Converter
Asynchronous Sample Rate Conversion (ASRC) is a post-processing sampling rate conversion library, implemented on Analog Devices’ Blackfin and SHARC. It is designed to convert between arbitrary sampling rate ratios and includes on-the-go computation of filter co-efficient, for standard audio sampling rates.
- DRC Dynamic range control
Dynamic Range Compression (DRC) is the difference between the loudest and quietest/softest signal levels that pass through the recording chain. Jasmin has implemented this post-processing algorithm using two Level Detection Process and Signal Gain Control Process.
