[SOLVED] voice recording using pyaudio

voice recording using pyaudio

i am trying to record voice using python. i tried to use the pyaudio module it saved a wav file on my computer but recorded a static voice. any suggestions?

import pyaudio
import wave

CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 44100
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "voice.wav"

p = pyaudio.PyAudio()

stream = p.open(format=FORMAT,
                channels=CHANNELS,
                rate=RATE,
                input=True,
                frames_per_buffer=CHUNK)

print("* recording")

frames = []

for i in range(0, int(RATE / CHUNK * RECORD_SECONDS)):
    data = stream.read(CHUNK)
    frames.append(data)

print("* done recording")

stream.stop_stream()
stream.close()
p.terminate()

wf = wave.open(WAVE_OUTPUT_FILENAME, 'wb')
wf.setnchannels(CHANNELS)
wf.setsampwidth(p.get_sample_size(FORMAT))
wf.setframerate(RATE)
wf.writeframes(b''.join(frames))
wf.close()

Solution

First, make sure your microphone is actually connected, on and not muted.

You are not providing a device index when opening the stream. This means that you will get the device that PyAudio considers the default. Which might not be your microphone.

Use the get_device_count and get_device_info_by_index methods of the PyAudio object in an interactive Python session. Print the dictionaries that get_device_info_by_index returns to determine which device index represents your microphone, and provide that index number as the input_device_index parameter when opening the stream.
