The Python package audio_wav handles all kind of audio files sample code:

.. code:: python

import LvAut.lvaut_THD as AUT filename='yourfile.wav' signal, sample_rate, channels=AUT.load(filename)

analyze_channels

.. code-block:: python import LvAut.lvaut_THD as AUT
filename='Device_Mic_THD_R_3.wav'
trigeFrequncy=400 ## this need sweep from high(above 400) to low sweep tone
stopananlysis=100 ## stop analyze_channels
channaelselect=1 ### if recording is dual channel ,leftchannel=1, rightchannel=2, otherwise no need to define
freq,thdh,thd_N,power,Freq_THD,thd_data,Freq_Power,PowerS,RubBuzz_data=AUT.analyze_channels(filename, trigeFrequncy,stopananlysis,channaelselect) print('FFT Frequency: %.1f Hz' % freq)
print("Sweep Max THD: %.4f%% " %thdh)
print("Sweep Max THD+N: %.4f%% Note, this is single tone use only " %thd_N)
print("Max Power: %.2fdB " %power)

============== -freq means: single tone , measured frequncy
-thdh means: Sweep Max THD -Freq_THD, measure THD's frequency -thd_data, measure THD's data -Freq_Power,measure Power's frequency -PowerS, measure Power's data -RubBuzz_data measure RB's data
