I am trying to use the PyAudio library to record guitar audio through my USB audio interface in a python project. When I use audio applications such as Audacity to save the audio I get a WAV (.wav) file which can be played using apps such as Groove music, windows media player etc. and I am able to manipulate the files as I need.
However, now I need to implement recording into the project and when I use PyAudio to record guitar input, it saves the audio as a WAVE Audio File (.wave) file which cannot be manipulated in the program and cannot be played using the playsound library. When I try to play it from my file manager it will only play using Itunes while Groove music and windows media player don't support it.
Anywhere I check online describes WAVE and WAV files as the same thing so I am unsure why I am having this issue. My code is as shown below. Any help or advice would be appreciated!
import pyaudio
import wave
from playsound import playsound
CHUNK = 1024
FORMAT = pyaudio.paInt16
CHANNELS = 2
RATE = 44100
RECORD_SECONDS = 5
WAVE_OUTPUT_FILENAME = "live_guitar_input.wave"
p = pyaudio.PyAudio()
stream = p.open(format=FORMAT,
channels=CHANNELS,
rate=RATE,
input=True,
frames_per_buffer=CHUNK)
print("NOW RECORDING")
frames = []
for i in range(0, int(RATE/CHUNK*RECORD_SECONDS)):
data = stream.read(CHUNK)
frames.append(data)
print("Finished 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()
playsound(WAVE_OUTPUT_FILENAME)
