How are vocals removed from songs to make instrumentals? Sometimes you can hear a little bit of the vocals still but how do they completely remove them without changing the rest of the sounds?
 There are a few different methods that can be used to remove vocals from a song and create an instrumental version, but it's important to note that none of these methods are 100% effective and some traces of the vocals may still be present in the instrumental.

One common method is to use a process called "phase cancellation" to remove the vocals from a stereo recording. This involves creating a duplicate of the original recording and inverting the phase of one of the duplicates. When the two recordings are played back together, the vocals, which are typically centered in the mix, will be cancelled out, while the other instruments and sounds will remain. However, this method can also result in a loss of some of the overall volume and clarity of the instrumental.

Another method is to use a vocal isolation plugin or software that uses algorithms to separate the vocals from the other instruments in a recording. These plugins are not always perfect and may still leave some traces of the vocals in the instrumental, but they can be effective in many cases.

It's also possible to create an instrumental version of a song by manually separating the vocals and other instruments using audio editing software. This can be a time-consuming and difficult process, but it can produce good results if done carefully.

In general, it is difficult to completely remove vocals from a song without affecting the rest of the sounds, and some traces of the vocals may still be
  Vocals removal from songs to create instrumentals is a process called "vocal isolation" or "vocal extraction." There are several techniques and tools used to achieve this, depending on the type of music, the quality of the recording, and the desired level of quality in the final instrumental. Here are some common methods:

1. Multi-band processing: This technique splits the audio signal into different frequency bands, allowing for more precise control over each band. By adjusting the gain, frequency, and other parameters in each band, the vocals can be isolated and removed without affecting the other instruments.
2. Spectral subtraction: This method uses a spectral analysis tool to identify the vocal frequency range and then subtracts that range from the original audio signal. The remaining instrumental audio is then processed to enhance the clarity and quality of the instruments.
3. Independent Component Analysis (ICA): ICA is a blind source separation technique that separates the audio signal into its constituent parts, including the vocals and instruments. By analyzing the frequency and time-domain characteristics of each component, ICA can isolate the vocals and remove them from the original audio.
4. Frequency-domain filtering: This method uses a variety of filters, such as low-pass, high-pass, band-pass, and notch filters, to remove or attenuate the vocals in the frequency domain. The filters can
