A package for recording, reading, manipulating, playing and writing sound files
Project description
audiomath is a package for Python programmers who want to record, manipulate, visualize or play sound waveforms. It allows you to:
Represent sounds as numeric arrays via the third-party Python package numpy (required). The arrays are contained within high-level objects, allowing common operations to be performed with minimal coding—for example: slicing and concatenation in time, selection and stacking of channels, resampling, mixing, rescaling and modulation.
Plot the resulting waveforms, via the third-party Python package matplotlib (optional).
Read and write uncompressed .wav files (via the Python standard library).
Read other audio formats using the third-party AVbin library (binaries are included in the package, for a selection of platforms).
Record and play back sounds using the third-party PortAudio library (binaries are included in the package, for a selection of platforms).
Play sounds using the alternative PsychPortAudio back-end, from the (optional) psychtoolbox package, allowing very precise control of latency
Plug in other recording/playback back-ends with moderate development effort.
