Questions about Python 3.x.
If the microphone does not have more than a certain amount of input for a certain period of time, the input is interrupted.
I'm thinking of a program that outputs the audio input from the speaker.
However, we accept input, but we cannot output it.
Can someone help me?
import pyaudio
import path
import structure
import time
Threshold = 50
SHORT_NORMALIZE= (1.0/32768.0)
CHUNK = 8192
FORMAT=pyaudio.paInt16
CHANNELS = 1
RATE = 16000
width = 2
TIMEOUT_LENGTH = 1
p=pyaudio.PyAudio()
defrms(frame):
count = len(frame) / width
format = "%dh"%(count)
shorts=struct.unpack (format, frame)
sum_square=0.0
for sample in shorts:
n=sample*SHORT_NORMALIZE
sum_square+=n*n
rms=math.power(sum_square/count, 0.5)
return rms*1000
stream=p.open(format=pyaudio.paInt16,
channels = 1,
rate = RATE,
frames_per_buffer = CHUNK,
input = True,
output=True)# Make input and output both true at the same time
while stream.is_active():
current=time.time()
end=time.time()+TIMEOUT_LENGTH
while current<=end:
data=stream.read(CHUNK)
ifrms(data)>=Threshold:
end=time.time()+TIMEOUT_LENGTH
print(rms(data))
current=time.time()
# output=stream.write(data)# Here the speaker will output sound (I don't want to write here)
output=stream.write(data)# I want to output sound from the speaker here
stream.stop_stream()
stream.close()
p.terminate()
print ("Stop Streaming")
Below are the answers in community wiki format written in the comments section.
After modifying the source code as follows, it worked as expected.
while stream.is_active():
current=time.time()
end=time.time()+TIMEOUT_LENGTH
save_data=[]# To store input data
while current<=end:
data=stream.read(CHUNK)
save_data.append(data)#Save Data
ifrms(data)>=Threshold:
end=time.time()+TIMEOUT_LENGTH
print(rms(data))
current=time.time()
# output stored data
for data in save_data:
output=stream.write(data)
