To generate an oscillating audio file with specific frequencies like 136.10 Hz, 432.69 Hz, and 1099 Hz, you can use audio synthesis software or programming libraries. Here’s a general guide on how to do it using Python and the numpy
and scipy
libraries:
- Install Python and necessary libraries: If you haven’t already, install Python on your system. You’ll also need to install
numpy
andscipy
libraries. You can install them via pip:pip install numpy scipy
- Write Python code: Use Python to generate the audio waveform with the desired frequencies. Here’s a basic example:
import numpy as np from scipy.io.wavfile import write # Parameters duration = 5 # Duration of the audio in seconds sample_rate = 44100 # Sample rate in Hz frequencies = [136.10, 432.69, 1099] # Frequencies in Hz amplitude = 0.5 # Amplitude of the waveform # Generate time array t = np.linspace(0, duration, int(sample_rate * duration)) # Generate waveform waveform = np.zeros_like(t) for freq in frequencies: waveform += amplitude * np.sin(2 * np.pi * freq * t) # Normalize waveform waveform /= np.max(np.abs(waveform)) # Scale waveform to 16-bit integers waveform_int = np.int16(waveform * 32767) # Write audio file write('oscillating_audio.wav', sample_rate, waveform_int)
- Run the code: Save the code into a Python file (e.g.,
generate_audio.py
) and run it using a Python interpreter. - Check the output: After running the code, you’ll find an audio file named
oscillating_audio.wav
in the same directory as your Python script.
This script generates an audio file with a duration of 5 seconds containing an oscillating waveform with frequencies of 136.10 Hz, 432.69 Hz, and 1099 Hz. You can adjust the parameters such as duration, sample rate, frequencies, and amplitude according to your preferences. Additionally, you can convert the generated WAV file to MP3 using audio conversion software or online tools if needed.
