Last Updated on January 19, 2024

Removing vocals from music tracks allows you to create instrumentals or prepare songs for karaoke sessions. This process involves isolating and eliminating the vocal component without disrupting the quality of the underlying music. Various methods and tools exist to accomplish this, ranging from simple software solutions to more complex audio engineering techniques.

To begin, you need to understand that the quality of vocal removal often depends on the original track's mix. Vocals mixed centrally with minimal effects are generally easier to remove. You can employ audio editing software that uses algorithms to subtract vocal frequencies from the track. Such software typically offers preset options for vocal removal, which you can fine-tune to achieve better results.

For a more advanced approach, using a digital audio workstation (DAW) with multi-band equalizers and phase inversion techniques will give you greater control. This process requires a more hands-on approach, adjusting frequencies and balancing the stereo field to remove the vocal while retaining the integrity of the music. Regardless of the method, patience and careful adjustments are key to obtaining a clean instrumental version of a song. Read on to learn how to remove vocals.

Fundamentals Of Vocal Removal

Removing vocals from music tracks requires understanding the composition of songs and the technology used to separate vocals. Here, you will learn the essential concepts and techniques employed in vocal removal.

Understanding Vocals And Instrumentals

In a typical music track, you have two main components: the vocals and the instrumentals. Vocals are the parts of the song where the singer's voice is the primary focus. Instrumentals consist of the background music provided by various musical instruments and beats. When you want to remove vocals, your aim is to isolate and eliminate the vocal component, leaving only the instrumental parts.

The Science Behind Vocal Removal

The vocal removal process exploits the stereo (left and right channels) properties of audio tracks. Most vocal tracks are mixed in the center of the stereo field, allowing them to be subtracted from the total mix. This subtraction is achieved through a technique known as phase cancellation, where the same audio wave in opposite phases cancel each other out. Using software, you can invert the phase of one channel and combine it with the other, which significantly reduces the vocal sounds.

Types Of Audio Files

Various audio file formats exist, each with its own qualities. When working with vocal removal, you should be aware of the most common types:

  • MP3: A widely-used compressed format that can result in loss of audio quality, which may affect the vocal removal process.
  • WAV: An uncompressed audio format that retains high quality but results in larger files.
  • AIFF: Similar to WAV, it's a lossless format preferred by professionals for high-quality sound.
  • AAC: A format that offers better compression than MP3 while trying to maintain audio quality.
  • FLAC: This is a lossless compression codec providing high fidelity without the large file size.

Your song file choice can influence the effectiveness of vocal removal due to the different ways these formats handle audio data.

Manual Vocal Removal Techniques

In order to remove vocals from music tracks manually, you need to understand the technical aspects of audio such as phase inversion and frequency isolation. Here are some techniques to achieve vocal removal with precision.

Inverting Phases

When using phase cancellation, you invert the phase of one element in a stereo track so that it will be cancelled out in the corresponding track. This method works great for extracting both vocals and instruments.

  1. Open your audio in an editing program.
  2. You need two tracks, full mix (vocals & instrumental) and vocal track (mono or stereo)
  3. Take the vocal channel and select the option to invert its phase.
  4. When you play both tracks simultaneously, the inverted phase of one track will cancel out the vocals.

Center Channel Reduction

In most mixes, the vocal are panned right up the center. With the being said, we can modify the center channel to reduce the vocals in a mix.

  1. Get the Waves Center audio plugin.
  2. Apply it to your track and turn down the center fader to taste.
  3. This effect will diminish the sound in the center of the stereo image, where vocals typically reside.

The effectiveness of this method is dependent upon the vocals being mixed in the center.

Isolating Frequencies

Isolating frequency bands where the vocals lie allows you to reduce vocals in a track.

  • Perform an analysis to identify the frequency range of the vocal.
  • Apply equalization (EQ) filters to reduce frequencies within this range. (Parametric is preferred over a graphic equalizer)
  • Listen to the result and make adjustments as needed to minimize the vocals without extremely affecting the rest of the audio.

Note: Complete removal isn't possible and may degrade the overall track quality.

Software Solutions For Vocal Removal

There are reliable software options that can help remove vocals from a song effectively. These tools utilize various processing techniques which can isolate the vocal components and allow you to extract or diminish them within a track.

Audacity And Other Audio Editors

Audacity is a popular, free open-source audio editing software that can facilitate vocal removal. You can access this feature in Audacity through the following steps:

  1. Import your music file by dragging it into Audacity or using File > Import > Audio…
  2. Select the track by double clicking on the waveform.
  3. Navigate to Effect > Vocal Reduction and Isolation…
  4. Adjust the settings as required to reduce or remove the vocals.

Other Audio Editors such as Adobe Audition and Reaper also provide similar vocal removal features, often with more advanced controls that may yield cleaner instrumental tracks.

Dedicated Vocal Removal Software

Dedicated vocal removal software is explicitly designed to separate vocals from tracks. These programs usually offer a more user-friendly interface and superior algorithms for vocal extraction, leading to higher-quality instrumental outcomes.

Vocal Removal Drawbacks

Below we've put together a list of issues you may experience. These issues will be different depending upon how the song was mixed, the format it is in, and other possible factors.

  • Background Vocals: It is unlikely you will be able to remove background vocals as they aren't usually panned in the center.
  • Reverb: This effect is usually panned hard left and right so you won't be able to remove it.
  • Complete Vocal Removal: To completely remove the vocals from a track isn't possible. There are great options out there, but keep your expectations realistic.

Practical Applications And Considerations

Removing vocals from music tracks serves specific purposes such as to make a karaoke version, an accompaniment, or instrumental mix for various uses. However, it is important to consider the legal framework surrounding the use of such tracks.

Creating Karaoke And Instrumental Tracks

For creating a karaoke version of a song, you typically need a clean instrumental backing track without the vocal component. This allows singers to perform without competing with the original vocalist. Similarly, an instrumental version can be valuable for dancers, background music in venues, or simply for listeners who enjoy the music without vocals. These can also be great additions as a B-side on vinyl, digital releases, or special editions of singles, offering an alternative listening experience.

Removing vocals from music tracks and using the resulting instrumental or karaoke versions must respect copyright laws. Always ensure you have the right to alter and use the original track. For example, playing a karaoke track in a public venue typically requires a public performance license, regardless if it's a commercially available karaoke version or one you've created yourself. Unauthorized use could lead to legal actions, so you must obtain the proper licenses before distribution or public use.
