Hello Python fellows,
I hope this question is not very far from the main topic of this list, but
I have a hard time finding a way to check whether audio data samples are
containing empty noise or actual significant voice/noise.
I am using PyAudio to collect the sound through my PC mic as follows:
FRAMES_PER_BUFFER = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 1
RATE = 48000
RECORD_SECONDS = 2import pyaudio
audio = pyaudio.PyAudio()
stream = audio.open(format=FORMAT,
channels=CHANNELS,
rate=RATE,
input=True,
frames_per_buffer=FRAMES_PER_BUFFER,
input_device_index=2)
data = stream.read(FRAMES_PER_BUFFER)
I want to know whether or not data contains voice signals or empty sound,
To note that the variable always contains bytes (empty or sound) if I print
it.
Is there an straightforward "easy way" to check whether data is filled with
empty noise or that somebody has made noise/spoke?
Thanks.
