Digital audio signal processing libraries on Analog Devices SHARC DSPs
We offer a number of high-performance, low footprint, customizable, real-time
digital audio signal processing libraries on the Analog Devices SHARC platform. These libraries have become industry standards and are used in numerous successful audio products ranging from mass-market to extreme high-end and are aimed at the most accurate audio reproduction and format conversion.
We license our libraries for large or small quantities on a flexible licensing model. Demo versions of the libraries are available upon signature of an NDA. Please contact us
for more details.
Sample Rate Conversion (SRC): High-performance, low footprint customizable, real-time sample rate conversion library supporting integer, ration of integer or arbitrary rate change for PCM signals. Support for unlimited sample rate change and sampling rate above 192kHz. Support for linear phase, minimal phase or apodyzing filtering. Synchronous or asynchronous sample rate conversion (asynchronous SRC requires special licensing terms).
Direct Stream Digital to PCM conversion with optional DSD over PCM support (DSD2PCM): High-performance, low footprint, customizable real-time Direct Stream Digital (DSD) to PCM conversion library. Supports single, double and quad rate DSD. Optional support for DoP (DSD over PCM) encoded signals. Support for linear phase, minimal phase or apodyzing filtering.
PCM to Direct Stream Digital conversion (PCM2DSD): High-performance, low footprint, customizable real-time PCM to Direct Stream Digital (DSD) conversion library, supporting single, double and quad rate DSD encoding in real-time on ADSP-214xx. Customizable modulator and up-sampling filters. Based on proprietary Vector Quantizer (VQ) modulation technology.
Digital Filtering (DF): Highly optimized FIR and IIR libraries includes support for Low-pass, High-pass, Cross-Overs, Shelf and Bell (cut or boost) IIR biquad coefficients computation. Unique all-pass FIR filter design with arbitrary phase response (phase equalizer). Phono equalizer with support for multiple deemphasis curves.
Pulse Width Modulation (PWM): Low foot print PCM to Pulse Width Modulation (PWM) library for applications to full digital amplifiers or D/A converters. Ulta-low MIPS / memory version available for subwoofer / bandwidth limited applications. Proprietary distortion reduction mechanism for Hi-Fi applications.
Our libraries offer unique performance / footprint metrics and many industry firsts.
We offer custom algorithm, mathematical modelling and digital signal processing design services ranging from mathematical modelling and development to high efficency implementations. Our experience encompasses a wide variety of platforms, ranging from Analog Devices
DSPs to proprietary, dedicated architectures. We are committed to the multi-core, multi-processor revolution and our understanding of the mathematical models behind algorithms gives us a head start in the optimal use of the power unleashed by these new technologies. We are also active around development tools for these new technologies.
Our main focus is the Analog Devices SHARC
platform and our implementation and optimization services are exclusive to this platform.
