Create a Voice Recorder using Python

Create a Voice Recorder using Python

To create a voice recorder using Python, you can use the sounddevice library to record audio and the numpy library to save the recorded audio to a file. Here's a step-by-step guide:

1. Install the required libraries:

You'll need sounddevice and numpy:

pip install sounddevice numpy

2. Implement the voice recorder:

Here's a basic voice recorder that records audio for a specified number of seconds and saves it as a WAV file:

import sounddevice as sd import numpy as np import wavio # Parameters RATE = 44100 # samples per second CHANNELS = 2 # number of channels (1: mono, 2: stereo) DTYPE = np.int16 # data type of the audio samples SECONDS = 5 # duration of recording # Record audio print("Recording...") audio_data = sd.rec(int(SECONDS * RATE), samplerate=RATE, channels=CHANNELS, dtype=DTYPE) sd.wait() # Wait until recording is finished print("Recording finished!") # Save as WAV file filename = "recording.wav" wavio.write(filename, audio_data, RATE, sampwidth=2) # sampwidth=2 for 16-bit audio print(f"File saved as {filename}")

When you run the script, it will record audio for 5 seconds and save it as "recording.wav" in the current directory. You can adjust the SECONDS variable to change the duration of the recording.

If you need more advanced features or want to integrate with a GUI library for a more user-friendly experience, there are other libraries and frameworks available. However, the above code provides a simple starting point for a voice recorder in Python.
