Python For Audio Signal Processing

This paper discusses the use of Python for developing audio signal processing applications. Overviews of Python language, NumPy, SciPy and Matplotlib are given, which together form a powerful platform for scientific computing. We then show how SciPy was used to create two audio programming libraries, and describe ways that Python can be integrated with the SndObj library and Pure Data, two exis...

Visualization of signal processing concepts

One of the key difficulties in a Signals and Systems course is the visualization of mathematically complex concepts presented. Thus, there is a need for graphica l too l s which enhance the s tudents ’ comprehension of these difficult concepts by allowing interactive learning. In this paper we present a software package to assist in the explanation and visualization of s ignal processing concep...

Audio signal processing by neural networks

In this paper a review of architectures suitable for nonlinear real-time audio signal processing is presented. The computational and structural complexity of neural networks (NNs) represent in fact, the main drawbacks that can hinder many practical NNs multimedia applications. In particular e,cient neural architectures and their learning algorithm for real-time on-line audio processing are disc...
