How to plot amplitude of audio file in python using scipy

certainly! plotting the amplitude of an audio file in python can be accomplished using libraries such as `scipy`, `numpy`, and `matplotlib`. below is a step-by-step tutorial on how to do that, including a code example.

### step 1: install the required libraries

before we start coding, make sure you have the required libraries installed. you can install them using pip:

### step 2: load the audio file

### step 3: plot the audio signal

once you have the audio data, you can use `matplotlib` to plot the amplitude over time.

### step 4: complete code example

here’s a complete example that demonstrates how to plot the amplitude of a wav audio file:

### explanation of the code

3. **plot function**: the `plot_audio_amplitude` function:
- creates a time array based on the number of samples and the sample rate.
- uses `matplotlib` to plot the audio amplitude over time.
- sets labels, title, and grid for better visualization.

4. **main execution**: the code checks if it's being run as the main module and invokes the functions with the specified audio file path.

### important notes

- this example assumes the audio file is in wav format. if your audio file is in a different format (like mp3), consider converting it to wav, or using a library like `pydub` or `librosa`.
- the audio data can be multi-channel (stereo), in which case you may want to plot each channel separately or compute the average amplitude.
- make sure the audio file path is correct, or you will get an error when trying to load the file.
