AlgorithmLib 3.9.26

audio algorithms to compute and test audio quality of speech enhencement

Audio test libs to compute audio quality and 3A performance by objective metrics
pcm,wav inputfiles is allowed,support different samplerate (invalid params are simply corrected to valid ones)



# How to install ?
#Install with pip:

simply use pip to install this toolkit



"pip install algorithmLib"

# Build and Install with git:

first step:

git clone https://g.hz.netease.com/majianli/audiotestalgorithm

second step:

simply run move2sys.prefix.bat before you building the project



# How to use?

    #just see ./demos/
