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.

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).
  • 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.

System Requirements

  • Windows XP Professional SP3 (32-bit only).
  • Windows Vista Business/Enterprise/Ultimate SP2 (32-bit only). It is recommended to install the software in a non-UAC-protected location.
  • Windows 7 Professional/Enterprise/Ultimate (32 and 64-bit).
  • Minimum of 2 GHz single core processor, 3.3 GHz dual core is recommended.
  • Minimum of 1 GB memory (RAM), 4 GB is recommended.
  • Minimum of 2 GB hard disk (HDD) space is required.
  • CrossCore® Embedded Studio for Analog Devices Processors.

Average Peak
16.7 42.7 6.8 40.72 41.11

  • This table highlights example SHARC processors and expected MIPS performance.
  • MIPS measured using a typical sample rate of Fs=48 kHz, optimal memory layout, worst case test vector, Stereo input and output, and running on an ADSP-21469 processor silicon revision 0.0.
  • “Data RAM” for one instance, includes Stack, Scratch, Instance/Stage, Minimum Input and Output Stereo Buffers.
  • The Buffer Size is 256 samples per channel, for both input and output.
  • The library tested was built using Crosscore Embedded Studio 1.0.1.
