Expressive Digital Signal Processing (DSP) package for Python
Expressive Digital Signal Processing (DSP) package for Python.
There are several tools and packages that let the Python use and expressiveness look like languages such as MatLab and Octave. However, the eager evaluation done by most of these tools make it difficult, perhaps impossible, to use them for real time audio processing. Another difficulty concerns expressive code creation for audio processing in blocks through indexes and vectors.
Prioritizing code expressiveness, clarity and simplicity, without precluding the lazy evaluation, and aiming to be used together with Numpy, Scipy and Matplotlib as well as default Python structures like lists and generators, AudioLazy is a starting project written in pure Python proposing digital audio signal processing (DSP), featuring a simple synthesizer, analysis tools, filters, biologial auditory periphery modeling, among other functionalities.
This is the first deploy of a pre-alpha package. For now, you can use already the audiolazy.lazy_itertools with element-wise operators, and create your own filters with the lazy_filter module. Some documentation will be included soon.
