Hi,
I am working on a small script which reads data from the Mic/StereoMix devices on Windows and want to be able to get the volume data for the R and L channels separately. I suspect it should be an easy thing to do, but couldn't find any examples searching online. Here is the code I have so far which gets the volume data as a single value, and sends it to the PeppyMeter program over http.
# script to read mic or any input device and send it to PeppyMeter for display
#!/usr/bin/env python3
import numpy as np
import sounddevice as sd
import requests
# specify the input device number in this case stereo mix
input_device = 18
peppy_url = 'http://localhost:8001/vumeter'
#peppy_url = 'http://192.168.1.240:8001/vumeter'
print(sd.query_devices())
print("\nEnter 'q' or 'Q' to Exit")
# function to handle data from audio input device
def audio_callback(indata, frames, time, status):
volume_norm = int(np.linalg.norm(indata) * 10)
#print(volume_norm)
print("|" * volume_norm)
# send json volume data
volume_data = {"left": volume_norm, "right": volume_norm, "mono":volume_norm}
response = requests.put(peppy_url, json=volume_data)
#print(response)
try:
stream = sd.InputStream(device=input_device, callback=audio_callback)
with stream:
while True:
response = input()
if response in ('', 'q', 'Q'):
break
except KeyboardInterrupt:
print('Interrupted by user')
except Exception as e:
print(type(e).__name__ + ': ' + str(e))
