*for manufacture test sweep tone sound file ,which also do combined some package from opensource.
audio file analyze USE only @ Lorry RUi
Main feature for this package
============================
1) Can set speaker and microphone level and get current friend_name
2) Can Open write sound file. like WAV/MP3 file read/write ( SOUNDFILE)
3) Can play(can set master speaker volume) and recording through microphone, which can point the
specific Mic. ( Sounddevice)
4) Can get single tone power and THD+N
5) can get sweep tone FR , THD, rub/buzz
6) can measure sound Spectrogram (For ML or noise study) ( librosa)

The Python package 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 (from HID level)
-----------------
.. code:: python
from LvAut.sound_level import setspeakervolume
setspeakervolume(40) ## set master speaker volume from 0 to 100
change current speaker volume and current Microphone level (from MS driver level)
----------------------------------
.. code:: python
import LvAut.lvaut_THD as AUT
a=AUT.speaker_volume(50)## set current speaker volume from 0 to 100(if mute will unmute),return reading after set
#a=AUT.speaker_volume(50,False) ## set current speaker volume from 0 to 100(never touch mute),return reading after set
#a=AUT.speaker_volume(50,False,False) ## only readout volume
### set Microphone
b=AUT.mic_level(50)## set current microphone level from 0to 100(if mute will unmute),return reading after set
#b=AUT.mic_level(50,False)## set current microphone level from 0to 100(never touch mute),return reading after set
#b=AUT.mic_level(50,False,False)## only readout volume
print(a,b)
change All speakers' volume and All Microphone level (from MS driver level)
----------------------------------
.. code:: python
import LvAut.lvaut_THD as AUT
a=AUT.speaker_all(50)## set all speakers volume from 0 to 100,return how many speaker done set
b=AUT.mic_all(50)## set all microphones level from 0to 100,return how many mics done set
print(a,b)
Get current system default speaker or current Microphone friendname (from MS driver level)
----------------------------------
.. code:: python
import LvAut.lvaut_THD as AUT
a=AUT.get_currentSpeakname() ## get current speaker name
b=AUT.get_currentMicname() ## get current Microphone name
print(a,b)
play master speaker
-----------------
.. code:: python
import LvAut.lvaut_THD as AUT
AUT.playsoundWin('yourfile.wav')
list all speaker and mics devices
-----------------
.. code:: python
import LvAut.device as sd
print(sd.query_devices())
recording master microphone(you can choose specific device)
-----------------
.. 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)
recording and play simultaneously
-----------------
.. code:: python
import LvAut.lvaut_THD as AUT
import LvAut.soundload as sf
import LvAut.device as sd
data, fs = sf.read(your sound file, frames=-1, start=None, stop=None, dtype=None, always_2d=False,
fill_value=None, out=None, samplerate=None, channels=None,
format=None, subtype=None, endian=None, closefd=True)
myrecording = sd.playrec(data, samplerate=fs, channels=1, dtype=None,
out=None, input_mapping=None, output_mapping=None, blocking=False,
device=device) # if None , will use default device
sd.wait() # Wait until recording is finished
AUT.write(outfile,myrecording,fs,'PCM_32') ## 'PCM_16','PCM_32', 'FLOAT', 'DOUBLE'
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 which analyze_sweep tone
----------------------------------
*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

analyze_sweep tone out chart setting
-----------------
.. code-block:: python
import LvAut.lvaut_THD as AUT

AUT.diplaychart(Freq_THD,thd_data,Freq_Power,PowerS,RubBuzz_data,chart_name="save_picture_name",channel= channaelselect)#display chart, pleae note : this function need import matplotlib
analyze sound file spectrogram : Convert a power spectrogram (amplitude squared) to decibel (dB) units This computes the scaling ``20 * log10(S / ref)`` in a numerically
-----------------
.. code-block:: python
import LvAut.lvaut_THD as AUT
import LvAut.lvspectrum as lvs
import numpy as np
filename='your soundfile.wav'
y, sample_rate, channels=AUT.load(filename)
S_scale = lvs.stft(y, n_fft=2048, hop_length=512)
Y_scale = np.abs(S_scale)
Y_log_scale = lvs.amplitude_to_db(Y_scale,ref=np.max)
print(Y_log_scale)
## print out all data
analyze sound file spectrogram(which need install matplotlib)#Compute dB relative to peak power
-----------------
.. code-block:: python
import LvAut.lvaut_THD as AUT
import LvAut.lvspectrum as lvs
import LvAut.lvdisplay as lvd
