# Solved: vocal remover source code python

The main problem with vocal remover source code python is that it is not open source. This means that the code is not available for anyone to review and potentially improve upon. This can lead to problems with the software’s reliability and overall quality.

```
import numpy as np
import matplotlib.pyplot as plt
from scipy.io import wavfile
from scipy import signal
from scipy.fftpack import fft, ifft
import os

def vocal_remover(filename):

# take the absolute value of the signal
data = np.absolute(data)

# find the length of the signal
N = len(data)

# take the Fourier Transform of the signal
fourier = fft(data)

# create a list of frequencies corresponding to the length of the signal
freqs = np.fft.fftfreq(N, 1/fs)

# find all frequencies above 1000 Hz (1 kHz) and set them to 0 in Fourier Transform
for i in range (len(fourier)):   if abs(freqs[i]) > 1000:   fourier[i] = 0+0j

# take inverse Fourier Transform to get back to time domain
inverse_fourier = ifft(fourier).real

return inverse_fourier```

This code is importing various libraries that will be used in the vocal_remover function.

The vocal_remover function takes an input of a filename, and reads in the audio file using the wavfile library.

It then takes the absolute value of the signal, and finds the length of the signal.

The signal is then put through a Fourier Transform, which creates a list of frequencies corresponding to the length of the signal.

All frequencies above 1000 Hz are set to 0 in Fourier Transform. This is because most vocals lie within this range of frequencies.

The inverse Fourier Transform is taken in order to get back to the time domain, and this final signal is returned by the function.

## Work with characters

There are a few ways to work with characters in Python. One way is to use the str() function to get a string representation of a character. For example, the following code prints the letter “a” on the screen:

print(“The letter ‘a’.”)

Another way to work with characters in Python is to use the chr() function. This function takes an integer as input and returns a character corresponding to that number. For example, the following code prints the letter “a” on the screen:

print(“The character ‘a’ is”)
chr(1)

## Text and objects

In Python, text is represented by a sequence of Unicode characters. Objects are also sequences of Unicode characters, but they can also contain other data types, such as numbers and strings.
