Summary¶
Note
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.
Features¶
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.
