  • No framework dependencies.

Product Details

DTS Symmetry for SHARC is an audio post-processing module developed by DTS Inc. for dynamically adjusting the audio gain to maintain the same level of perceived loudness for a stereo source without cause audible distortion. It is primarily designed for audio systems where the audio level of the source is highly variable.

Licensing

Each module supports the Analog Devices, Inc. (ADI) Blackfin or SHARC Processor family and is a licensed product that is available in object code format. Recipients must sign or accept a license agreement with ADI prior to being shipped or downloading the modules identified in the license agreement.

  • MIPS measured using Fs = 48kHz, stereo input and output, optimal memory layout, running on a ADSP-21469.
  • Code compatible across all ADSP-214xx processors, with silicon anomaly workarounds implemented.
  • "Data RAM" for one instance, includes Stack, Scratch, Instance/State, Minimum Input and Output Single Buffers.
  • Both input and output buffer size used for data memory calculation is 256 bytes (utilizing a frame size of 32 samples per channel).
  • Frame size used for MIPS measurement is 256 samples per channel.
