Product Details

DTS Boost for SHARC is an audio post-processing module developed by DTS Inc. for maximizing the perceived loudness for a stereo source without cause audible distortion. It is primarily designed for audio speaker systems that have limited power output.

DTS Boost for SHARC has been highly optimized to run on the Analog Devices’ SHARC ADSP-214xx processor family. The API of the DTS Boost for SHARC software library is designed to enable software developers to use in a C application, and for system integrators to build it into a complete system.

Features

User configurable boost gain.
User configurable speaker protection factor to prevent damage to speakers on large gains.
Sampling rates supported: 8, 11.025, 12, 16, 22.05, 24, 32, 44.1 and 48 kHz.
Block size supported: 256 samples per channel.
Supports stereo inputs with mono option (downmix performed)
Target Processor: Code compatible across the SHARC ADSP-214xx family of processors.
DTS Certified on ADSP-21462/5/7/9, ADSP-21471/2/5/8/9, and ADSP-21481/2/3/5/6/7/8/9 processors.
Release format: Object code module with C source wrapper.
Input format: non-interleaved multichannel 32-bit floating point samples.
Output format: non-interleaved multichannel 32-bit floating point audio samples.
Framework dependencies: None
