python record audio code example
Example 1: python record audio from microphone
import pyaudio
import wave
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 44100
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "output.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()
Example 2: how to record a wav file using python
import pyaudio
import wave
# the file name output you want to record into
filename = "recorded.wav"
# set the chunk size of 1024 samples
chunk = 1024
# sample format
FORMAT = pyaudio.paInt16
# mono, change to 2 if you want stereo
channels = 1
# 44100 samples per second
sample_rate = 44100
record_seconds = 5
# initialize PyAudio object
p = pyaudio.PyAudio()
# open stream object as input & output
stream = p.open(format=FORMAT,
channels=channels,
rate=sample_rate,
input=True,
output=True,
frames_per_buffer=chunk)
frames = []
print("Recording...")
for i in range(int(44100 / chunk * record_seconds)):
data = stream.read(chunk)
# if you want to hear your voice while recording
# stream.write(data)
frames.append(data)
print("Finished recording.")
# stop and close stream
stream.stop_stream()
stream.close()
# terminate pyaudio object
p.terminate()
# save audio file
# open the file in 'write bytes' mode
wf = wave.open(filename, "wb")
# set the channels
wf.setnchannels(channels)
# set the sample format
wf.setsampwidth(p.get_sample_size(FORMAT))
# set the sample rate
wf.setframerate(sample_rate)
# write the frames as bytes
wf.writeframes(b"".join(frames))
# close the file
wf.close()
Example 3: how to get sound in python
#if on windows
import winsound
Example 4: record and store audio in pythn
import pyaudio
import wave
chunk = 1024 # Record in chunks of 1024 samples
sample_format = pyaudio.paInt16 # 16 bits per sample
channels = 2
fs = 44100 # Record at 44100 samples per second
seconds = 3
filename = "output.wav"
p = pyaudio.PyAudio() # Create an interface to PortAudio
print('Recording')
stream = p.open(format=sample_format,
channels=channels,
rate=fs,
frames_per_buffer=chunk,
input=True)
frames = [] # Initialize array to store frames
# Store data in chunks for 3 seconds
for i in range(0, int(fs / chunk * seconds)):
data = stream.read(chunk)
frames.append(data)
# Stop and close the stream
stream.stop_stream()
stream.close()
# Terminate the PortAudio interface
p.terminate()
print('Finished recording')
# Save the recorded data as a WAV file
wf = wave.open(filename, 'wb')
wf.setnchannels(channels)
wf.setsampwidth(p.get_sample_size(sample_format))
wf.setframerate(fs)
wf.writeframes(b''.join(frames))
wf.close()
