AlgorithmLib 0.0.12

audio algorithms to compute and test audio quality of speech enhencement

Audio test lib 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)

"""
:param metrics: G160/P563/POLQA/PESQ/STOI/STI/PEAQ/SDR/SII/LOUDNESS,
# g160 no samplerate limiting,  WAV/PCM input , three inputfiles :clean,ref,test no duration limiting;
# P563 8000hz( only 8k spectrum is being calculated), WAV/PCM input , single inputfile, duration < 20s;
# POLQA nb mode  8k  swb mode 48k :WAV/PCM input , 2 inputfiles: ref,test: duration < 20s;
# PESQ nb mode 8k   wb mode  16k ,WAV/PCM input ,2 inputfiles: ref,test: duration < 20s;
# STOI no samplerate limiting; 2 inputfiles: ref,test, no duration limiting;
# STI >8k(only 8k spectrum is being calculated), WAV/PCM input , 2 inputfiles: ref,test ,duration > 20s;
# PEAQ no samplerate limiting, WAV/PCM ,2 inputfiles: ref, test , no duration limiting;
# SDR no samplerate limiting; WAV/PCM input ,2 inputfiles:ref,test: no duration limiting;

there are different params for different metrics,if params you speend is valid,they will be corrected to valid ones while calculating
:param testFile: the files under test ,
:param refFile: the reference file ,FR metrics need POLQA/PESQ/PEAQ
:param cleFile: clean file ,G160 need 
:param samplerate: samplerate,option ,pcmfile  default = 16000
:param bitwidth: bitwidth, option,pcmfile  default = 2
:param channel: channels, option,pcmfile  default = 1
:param refOffset: offset for ref file,option
:param testOffset: offset for test file ,option
:return
