Project description

Python-SoXR

High quality, one-dimensional sample-rate conversion library for Python

Installation

pip install soxr

If installation fails, upgrade pip with python -m pip install --upgrade pip and try again.

Basic usage

import soxr

y = soxr.resample(
    x,          # 1D(mono) or 2D(frames, channels) array input
    48000,      # input samplerate
    16000       # target samplerate
)

Output is 2D numpy.ndarray with shape (frames, channels).
