Add functionality to read wav file

[kootenpv]

Unfortunately doesn't work with:

wf = wave.open("my.wav", "rb")

self.stream = p.open(
    format=p.get_format_from_width(wf.getsampwidth()),
    channels=wf.getnchannels(),
    rate=wf.getframerate(),
    output=True,
    stream_callback=self.callback,
)

I think it should work like this, i will try it next weekend: (pseudo code):

import pyaudio import wave import numpy as np from Realtime_PyAudio_FFT import Visualization

Read audio file

audio_file = "path_to_audiofile.mp3" wf = wave.open(audio_file, 'rb')

Initialization of the PyAudio library and the Visualization object

p = pyaudio.pyAudio() visualization = visualization()

Set parameters for audio playback

stream = p.open( format=p.get_format_from_width(wf.getsampwidth()), channels=wf.getnchannels(), rate=wf.getframerate(), output=True, stream_callback=visualization.callback, # Callback callback function callback for animation )

Audio creation

data = wf.readframes(1024) whiledata: stream.write(data) data = wf.readframes(1024)

End the thread and clean up the resources

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

Did you manage to write the full code and does it work?

do you want to specify the path to the file and see everything just like with the microphone? I could make a fork and add such functionality there, if someone really needs it :)
