Acoustic Signal Measurement Utilities

Acoustic Signal Measurement Utilities

The asmu Python package enables multichannel real-time audio playback, processing and recording. It is implemented in pure Python with a few additional packages:

• numpy - Is the fundamental package for scientific computing, array manipulation and signal processing.
• sounddevice - Is a Python wrapper for the PortAudio functions. It is used for the communication with the soundcard or audio interface.
• soundfile - Is an audio library to read and write sound files through libsndfile.
• pyFFTW - A pythonic wrapper around FFTW, presenting a unified interface for all the supported transforms.

The main focus of asmu is modularity and easy expandability. It provides a few base classes, to implement nearly every "audio processor". Additionally, asmu offer some pre implemented audio processors, that can be used right away.
