        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) 
        
        change master speaker volume 
        -----------------
        .. code:: python    
        
        		import LvAut.lvaut_THD as AUT  
        		AUT.setspeakervolume(40)  ## set master speaker volume from 0 to 100
        		
        		
        play master speaker  
        -----------------
        .. code:: python   
         
        		import LvAut.lvaut_THD as AUT
        		AUT.playsoundWin('yourfile.wav')
        		
        	   	   
        list all speaker and mics devices  
        -----------------
        .. code:: python 
           
        		import LvAut1.device as sd
        		print(sd.query_devices())
        		
        		
        
        recording master speaker  
        -----------------
        .. code:: python    
        
        		import LvAut.device as sd
        		import LvAut.lvaut_THD as AUT
        		fs = 44100  # Sample rate
        		seconds = 5  # Duration of recording
        		myrecording = sd.rec(int(seconds * fs), samplerate=fs, channels=1)  # using default mic
        		#myrecording = sd.rec(int(seconds * fs), samplerate=fs, channels=1, device="Microphone (Logitech Webcam C930e), Windows DirectSound")
        		sd.wait()  # Wait until recording is finished
        		AUT.write("test.wav",myrecording,fs)
        
        	   
        analyze_sweep tone
        -----------------
         
        .. 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_sweep  
        		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_sweep(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("spectrum Max Power:       %.2fdB " %power)     
        		
        
        
        	
        output explain	
        ==============   
        
        	1)freq  means: single tone , measured frequency  
        	1.1)thd_N   means: single Max THD+N  	
        	2)thdh   means: Sweep Max THD  
        	3)Freq_THD, measure THD's frequency
        	4)thd_data, measure THD's data
        	5)Freq_Power,measure Power's frequency
        	6)PowerS,  measure Power's data
        	7)RubBuzz_data    measure RB's data
