pandinosaurus / logmmse Goto Github PK

The fork improved on the original version to support Python 3, fixed a few bugs, and made it importable from other Python scripts

A python implementation of the LogMMSE speech enhancement/noise reduction alogrithm

pip install logmmse

from logmmse import logmmse_from_file
out = logmmse_from_file('sample.wav')
print(out)

data (Mandatory)

A 1d or 2d (number of frames, channels) Numpy array representing the audio signal

Supported format: 32-bit floating-point, 32-bit PCM, 16-bit PCM, and 8-bit PCM, see https://docs.scipy.org/doc/scipy/reference/generated/scipy.io.wavfile.read.html

sampling_rate (Mandatory)

Sampling rate of the data (e.g. 16k/44.1 kHz)

output_filename

filename of the wave output. If none, no file would be generated

the output format would be the same as input

return

A 1d or 2d (number of frames, channels) Numpy array representing the enhanced signal

input_filename (Mandatory)

Filename of the wave input

supported format: 32-bit floating-point, 32-bit PCM, 16-bit PCM, and 8-bit PCM, see https://docs.scipy.org/doc/scipy/reference/generated/scipy.io.wavfile.read.html

output_filename

See above
