PyAudio Oversampling on Windows 10
Comment
1 / 1
PyAudio oversampling on Windows 10 can be achieved by using the Resampy
library, which is a pure Python library that provides resampling functions. Here's an example code snippet that demonstrates how to use Resampy
to oversample an audio signal using PyAudio on Windows 10:
pythonimport pyaudio
import numpy as np
import resampy
# Create PyAudio instance
pa = pyaudio.PyAudio()
# Open the audio stream
stream = pa.open(format=pyaudio.paFloat32, channels=1, rate=44100, input=True, output=True, frames_per_buffer=1024)
# Loop over the stream
while True:
# Read a chunk of audio data
data = stream.read(1024)
# Convert the data to a numpy array
data = np.frombuffer(data, dtype=np.float32)
# Resample the data to 48000 Hz using Resampy
data = resampy.resample(data, 44100, 48000)
# Convert the data back to a byte string
data = data.astype(np.float32).tobytes()
# Write the resampled data to the output stream
stream.write(data)
In this example, we first create a PyAudio instance and open an audio stream with a sample rate of 44100 Hz. We then loop over the stream, reading a chunk of audio data at a time. We use Resampy
to resample the data to 48000 Hz and write the resampled data back to the output stream.
Note that Resampy
is a third-party library and needs to be installed separately using pip
.
