Some software components in this tool flow are prototypes and will be updated in Version 2 of the library.
|
|
The underlying Digital Signal Processing (DSP) blocks are however fully functional. Future updates will
|
|
enhance the features and flexibility of the design tool.
|
|
|
|
lib_audio_dsp is a DSP library for the XMOS xcore architecture. It facilitates the creation of
|
|
multithreaded audio DSP pipelines that efficiently utilise the xcore architecture.
|
|
|
|
The library is built around a set of DSP function blocks, referred to in the documentation as *Stages*,
|
|
which have a consistent API and can be combined to create many different designs.
|
|
|
|
A tool for easily
|
|
combining stages into a custom DSP pipeline is provided. DSP pipeline parameters can be adjusted and
|
|
tuned on the fly via a PC based tuning interface, and utilities for hardware controls are also provided.
|
|
|
|
lib_audio_dsp includes common signal processing functions optimised for the xcore, such as:
|
|
|
|
* biquads and FIR filters.
|
|
* compressors, limiters, noise gates and envelope detectors.
|
|
* adders, subtractors, gains, volume controls and mixers.
|
|
* delays and reverb.
|
|
|
|
These can be combined together to make complex audio pipelines for many
|
|
different applications, such as home audio, music production, voice
|
|
processing, and AI feature extraction.
