Tutorial — Vocal Removal and Isolation

This page describes techniques which, on some stereo tracks, may allow you to remove or isolate vocals (or other parts of a recording) from the rest. There is no universal, reliable way of doing this without having the original multi-track recordings. Different tracks will require different techniques to achieve maximum possible attenuation or isolation. This will depend on where the vocals are positioned in the stereo field, and on their frequency content compared to the rest of the audio.

Case 1: Vocal Removal with vocals in the middle and instruments spread around them

If the vocals are panned in the center of a stereo track the so-called «vocal removal» technique can sometimes be effective by removing what is common to both tracks (that is, the vocals), leaving behind what is different (that is, the instrumentals).

The underlying technique in Audacity is to split the stereo track into its left and right channels, make both mono, invert all (or a selected part) of one of them then play back the result. Note, this removes everything panned in the center, not just vocals, and returns a dual mono result (both channels have the same audio). In some music this could mean removing instrumental parts. Removal of the vocals can often be incomplete leaving artifacts behind; this is especially true where there are backing vocals or where reverb (echo) has been applied as this spreads sound sources and makes them very hard to extract from each other.

Vocal Reduction and Isolation

Audacity includes a Nyquist plugin effect to automate the steps involved in Case 1, at Effect > Vocal Reduction and Isolation . If you only wanted to automate Case 1 in the Vocal Reduction and Isolation effect, you would choose the option «Remove Center Classic (Mono)». As in Case 1 above, this removes the whole frequency spectrum of center-panned audio and returns a dual mono track.

However the default option for Vocal Reduction and Isolation «Remove Vocals» is to be preferred in most cases because this returns stereo output.

Vocal Reduction and Isolation also lets you specify frequencies above which or below which audio is not removed or isolated. This can help cure the common problem where center-panned bass or Hi-hat is also removed when removing vocals.

Case 2: Vocal Removal with vocals in one channel and everything else in the other

If you have an unusual stereo track where the vocals are mixed hard into one channel and everything else hard into the other channel you can split the stereo track into separate channels then delete the vocal channel. To isolate the vocals, rather than remove them, delete the other channel.

To split a stereo track, click on the downward pointing arrow at the top of the Track Control Panel then click on Split Stereo to Mono . To delete the unwanted channel, click the [X] to left of the downward pointing arrow. If you accidentally delete the wrong channel, use Edit > Undo to get it back.

Case 3: Vocal Isolation

You can use the Vocal Reduction and Isolation effect to attempt to isolate the vocals by choosing one of the Isolate Vocals in the Action dropdown menu in the dialog. But note that the end result may not be total vocal isolation or even satisfactory isolation of the vocals; it all depends on how the original recording was engineered.

A technique using Audacity for vocal isolation

An Audacity user (Marco Diego) suggested the following technique for using Audacity to attempt to isolate vocals. It will not work successfully in all cases.

It is sometimes possible to isolate vocals by using Audacity’s Noise Reduction to capture the noise profile of a song that has had vocals removed, then run Noise Reduction with that profile on the original mix before vocals were removed.

1. Make a copy of your original stereo track
   1. Select the whole track (click in empty space in its Track Control Panel for example where it says «Hz»)
   2. Copy the track with Edit >Copy
   3. Create a new stereo track with Tracks > Add New >Stereo Track
   4. Use Edit >Paste to make a copy of the original track in the new stereo track
   1. Use the steps above to create a track with isolated vocals.
   2. Import the original song into Audacity again. Download the Bass to Center Nyquist plugin and install it. Use this plugin to move the bass frequencies to center.
   3. Remove the drums (and the vocals) from the center using Effect >Vocal Reduction and Isolation .
   4. Finally mix the isolated vocals back in.

   Using an instrumental track to isolate the vocals

   In order for this to work you will need to have a studio version of the instrumental track in which the instrumental part is identical to the full track. Many studios release the instrumental tracks (with and without backup vocals) for use with things like karaoke. There are places online where you can buy these tracks (Karaoke-Version.com for example and some records even have them on the B side). MP3 encoding of one or both versions will create small differences that will make this technique less effective.

   As opposed to the final mono track you get from removing vocals, this method will leave you with a full stereo track. As such, it becomes more important to try and match the quality of both tracks and align them before you isolate the vocals.

   1. Open Audacity and Import both the regular and instrumental tracks.
   2. Select one of the tracks and use the Clip-handle drag-bars to roughly align the two tracks.
   3. Zoom in really close and then zoom in more.
   4. Exact alignment is critical. Pick a peak or trough in the left channel of one track and match it precisely with the left channel of the other track. If the alignment isn’t right the process won’t work.
   5. Select the instrumental track, and invert it using Effect >Invert .
   6. Use Ctrl + A to select all of both tracks.
   7. Use Tracks > Mix >Mix and Render .

   You should now have one combined track that should have a more diminished amplitude where the vocals were kept and the instrumentation removed.

   Vocal Reduction and Isolation

   Vocal Reduction and Isolation attempts to remove or isolate center-panned audio from a stereo track. Vocals are sometimes (but not always) recorded in this way. The simplest and quickest removal method subtracts one channel from the other, but the result will be (dual) mono. This method is available at «Remove Center Classic: (Mono)» under Action. All other «Remove» options in this effect preserve the stereo image.

   The Isolate options all return (dual) mono output. The narrowness of the center slice can be adjusted with the «Strength» slider. Center isolation is not possible using the classic subtraction method.

   The Analyze option displays the amount of correlation between the stereo channels and the degree of likelihood that center removal or isolation will work effectively.

   If you apply this effect with an envelope present then there is a bug whereby the envelope is removed and the audio reverts to its full amplitude state prior to the effect being applied.

   Action

   Bandwidth Limited Actions

   The Low Cut and High Cut sliders affect these actions.

   • Remove Vocals: to mono: (default). If the audio is center-panned, removes the vocal range defined by the Low Cut and High Cut sliders, and returns it as a dual-channel mono track. Audio is said to be «center-panned» if it is common to both left and right channels. Cancellation of center panned audio is achieved by the well known «invert and mix» method.
   • This setting is identical to the «Vocal Remover > Remove frequency band» effect in previous versions of Audacity.
   • The Strength slider is not used when «Remove Vocals: to mono:» is selected.
   • Remove Vocals: If the audio is center-panned, removes the vocal range defined by the Low Cut and High Cut sliders, and returns it as a stereo track.
   • Isolate Vocals: If the audio is center-panned, extracts the slider-defined vocal range and returns it as a (dual) mono track.
   • Isolate Vocals and Invert: If the audio is center-panned, extracts the slider-defined vocal range and returns it as an inverted (dual) mono track.
   • This option is equivalent to applying the Isolate Vocals option and then inverting.
   • The «and Invert» options may be useful when processing using duplicated tracks. See the examples below.

   Full Spectrum Actions

   The Low Cut and High Cut sliders have no effect with these actions.

   • Remove Center: to mono: Removes all audio (the whole frequency spectrum) that is common to both left and right channels and returns a (dual) mono track. Cancellation of center panned audio is achieved by the well known «invert and mix» method.
   • This setting is identical to the «Vocal Remover > entire spectrum» effect in previous versions of Audacity.
   • None of the sliders are used when «Remove Center: to mono» is selected.
   • Remove Center: Removes all audio (the whole frequency spectrum) that is common to both left and right channels and returns a true stereo track.
   • Isolate Center: If the audio is center-panned, extracts the whole frequency spectrum and returns it as a (dual) mono track.
   • Isolate Center and Invert: If the audio is center-panned, extracts the whole frequency spectrum from and returns it as an inverted (dual) mono track.

   This option is equivalent to applying the Isolate Center option and then inverting.

   Analysis Action

   • Analyze: Tells you how great the chances are of a successful vocal reduction or isolation. It returns also the average Pan position for the selected audio. See below for an in-depth explanation.

   This option only analyzes the audio. The selected audio is not modified by the effect.

   Strength

   The shape of the center is not a thin band but rather like a tent with a pole in the middle. This means that there will always audio from other pan positions included. The Strength slider modifies the shape of the center. Higher values increase the degree of reduction or isolation. Zero is off (no reduction or isolation). This slider has no effect with the «Remove Center Classic: (Mono)» choice.

   Remove

   • Less than 1.0: Produces a notch with a V shape like a ship’s keel, but also with a sharp point. Use this setting to preserve some amount of the center.
   • 1.0 — the default: Produces a notch with a V shape. The power distribution is preserved. This is the ideal setting for most cases.
   • Greater than 1.0: Produces a notch with a U shape. This removes some audio adjacent to the center, as well as the center. Note that this will not remove stereo reverberation since it is distributed over the entire pan width.

   Isolate

   • Less than 1.0: Produces a peak like a U shape upside down, similar to an arch. Only extreme left and right are eliminated.
   • 1.0 — the default: Produces a peak like a V shape upside down. The power distribution is preserved. You might want a higher value when a lot of side audio leaks in. This is also the recommended setting when working with two tracks (options with . and Invert).
   • Greater than 1.0: Produces a peak with an A shape like the Eiffel Tower (with a sharp point). This will attenuate most of the side energy but might produce artifacts or musical noise. Normalize the audio after using Isolate with a high strength setting.

   Low Cut for Vocals

   All actions with Vocals in the name use this value. The frequencies below will either not be removed or not be included in the isolated audio. It is useful to exclude bass and kick drum. The default value of 120 Hz is good for most lead vocals, or even low male voices. You can enter a higher value around 170 Hz for female voices and about 230 Hz for those of children.

   This control only affects «Actions» that contain the word Vocals in their name.

   High Cut for Vocals

   All actions with Vocals in the name use this value. The frequencies above will either not be removed or not be included in the isolated audio. It is useful to exclude high sounds like bells, cymbals or Hi-hat. Note that human sounds like S or Z can also be very high in frequency — 5000 to 8000 Hz, so listen carefully to the preview.

   This control only affects «Actions» that contain the word Vocals in their name.

   Interpreting the analysis results

   It is recommended to analyze the audio prior to actual processing of the effect. Analysis is very fast compared to the time needed for processing.

   The two important values are:

   • Pan Position: This gives the average pan position for the whole selected audio. The value of the track pan slider is not included in this calculation.
   • Correlation: This is a measure for the similarity of the two channels. Values of +/-100 mean that the channels are exactly the same, even if one is inverted. A value of 0 means no relationship. It is fruitless to attempt removal or isolation in these cases. The ideal value is normally around +50. Values below 0 are rare and indicate that the stereo width is more than 100%. Inverting one channel makes the correlation positive.
   1. The correlation should be fairly high (around 100) which would indicate that there is indeed only the voice.
   2. Copy the value for the Pan Position. Double-click in the Pan slider to open the adjustment dialog then paste in the value with reversed sign (that is, put a minus sign in front of a positive value and a positive sign in front of a negative value).
   3. Mix and render the track. The voice will now be exactly centered and you can remove or isolate it.
   4. Do not forget to readjust the selection.

   Limitations

   • The input must be a true stereo track and not mere (dual) mono.
   • Stereo Reverberation will not be fully removed because it is independently distributed over the whole stereo image.
   • Naturally the plug-in does not know what kind of audio is in the center. All is removed or isolated equally, whether vocals, bass or solo instruments.
   • This effect is quite slow, except for the «Remove Center Classic: (Mono)» and «Analyze» actions.

   The whole processing is done in memory. Long selections (over half an hour) might therefore cause Audacity to crash.

   Examples

   • Creating a Karaoke version from an original song
   • Creating an acapella version from an original song
   • Alternative to «Auto Duck» with podcasts
   • Removing excessive stereo reverb from a vocal or instrument track.
   • Removing random system noise from a two channel recording of a mono source.
   • Removing single words or phrases
   • Amplifying dialogs in a movie.
   • Converting stereo files into 3.1, 5.1 and other multi-channel formats.
   • Extracting instrument solos
   • Blending between original, karaoke version and vocals only
   • Correcting the pan position
   • Measuring similarity between two mono tracks
   • Applying a brick wall filter to mono tracks

   Как сделать минусовку в Audacity

   

   Как сделать минусовку? Этот вопрос мучает многих (особенно начинающих) вокалистов.

   Как сделать минусовку с помощью обычного компьютера, не имея в своем распоряжении профессиональных программ?. Действительно, зачем исполнителю лишние проблемы. Каждый хочет, чтобы задача удаления голоса из песни решалась в два простых клика. Но на практике несколько иначе.

   В своей статье «Как удалить голос из песни» я уже рассказывал о том, как сделать минусовку. Однако я использовал для этого профессиональный аудиоредактор Adobe Audition 3.0. Это платный продукт и не каждый имеет возможность его приобрести (разве что использовать ломаную версию программы). В этой же статье речи пойдет о том, как сделать минусовку с помощью программы Audacity. Несмотря на то, что Audacity является бесплатным редактором, он обладает всеми необходимыми функциями для расширенной работы с аудио материалом. Это отличная альтернатива таким программам как Wavelab, Sound Forge и Adobe Audition.

   Еще раз хочу отметить, что сделать качественный минус с помощью всех описанных мною способов невозможно. В любом случае после всех проделанных опереций избавиться полностью от вокала не удастья. Помимо этого вы здорово потеряете в качестве (инструменты будут звучать намного скуднее). Сделать действительно качественный минус можно только, написав его с нуля.

   Как сделать минусовку в Audacity

   Вариант первый (Моно)

   1. Запускаем программу, выбираем Файл / Открыть или Ctrl+O и загружаем необходимый файл

   

   

   2. В левом верхнем углу, возле названия композиции из списка выбираем пункт Split Stereo Track (разделить стерео трек).

   

   Теперь у нас есть два трека.

   3. В том же списке для каждого трека выбираем режим моно.

   

   4. Выделяем один из треков и выбераем пункт меню Эффекты / Инвертирование

   

   5. Сохраним результат. Выберем Файл / Экспортировать (Ctrl+Shift+E), укажем место экспортирования и тип файла.

   

   

   Ария – Осколок льда (до обработки)

   Ария – Осколок льда (после обработки)

   Вариант второй (Стерео)

   1. Запускаем программу и открываем необходимый файл.

   2. Выбираем пункт Эффекты / Vocal Remover (for center – panned vocals)…

   

   3. Устанавливаем следующие параметры:

   А . Remove vocals or view Help – Remove vocals (удаление вокала);

   В . Removal choice – Remove frequency band (удаление полосы частот);

   С . Frequency band lower and upper limit – 200 16000 (нижний и верхний пределы удаления полосы частот; устанавливаеться эксперементальным путем, в зависимости от композиции).

   

   4. Сохраняем результат Ctrl+Shift+E

   Ария – Осколок льда (до обработки)

   Ария – Осколок льда (после обработки)

   Такую фонограмму можно использовать на выступлениях местного масштаба или на домашних вечеринках. Для более масштабных мероприятий необходим совсем другой подход.

   How to remove vocals from a song in Audacity? This is a common question asked by Audacity users, who may be familiar with the process but have a hard time when the most used methods fail. This post is meant to give step-to-step instructions on how to remove vocals from a song using this tool in 3 different ways, so users can make an informative decision if the current way doesn’t work out as expected.

   Methods	Effectiveness	Difficulty
   Using the Vocal Reduction and Isolation Effect	The most common way works for most songs.	Easy
   Using Split Stereo to Mono	A way works for stereo tracks with vocals mixed into one channel.	Easy
   Using Noise Reduction	A new way of using noise reduction to get a clear vocal removal.	Easy

   3 Easiest Ways to Remove Vocals from a Song Audacity

   Next, we will discuss three easy methods to remove vocals from recording tracks in Audacity. These techniques offer practical ways to isolate or eliminate vocals, giving you more flexibility in working with your audio tracks. Let’s explore these step-by-step approaches. Environment: I’m using the newest 3.3.3 version of Audacity on Windows 11.

   ✨Using the Vocal Reduction and Isolation Effect

   The first technique in Audacity involves the vocal reduction and isolation feature of the Nyquist plugin. Vocal reduction and isolation in Audacity returns a stereo output. It also lets you define specific frequencies to avoid removing other elements like bass or Hi-hat unintentionally. This method works for the majority of songs and returns the stereo output, but it is not always successful in completely removing vocals and can unintentionally remove other audio elements along with the vocals. Step 1. Download the open Audacity. Step 2. Go to «File» > «Import» > «Audio» to select the song. Step 3. Click «File» > «Export» > «Export as MP3/WAV/OGG…» to keep a backup. Name it and click «OK«. Step 4. Click «Close» on the original audio track and import the newly exported file. Step 5. Click «Select» > «All«. Step 6. Click «Effect» > «Special» > «Vocal Reduction and Isolation» > «Action» > «Remove Vocals«.

    Tip You can use the Nyquist plugin effect and choose the option «Remove Center Classic (Mono)» to automate the effect here, which removes the entire frequency spectrum of center-panned audio and results in a dual mono track. But still, «Remove Vocals» is preferred.

   

   Step 7. Click «Play» to listen to the result. Share these newest ways to remove vocals in Audacity in 2023 with your friends.

   ��Using Split Stereo to Mono

   For stereo tracks with vocals mixed into one channel and other elements in the other channel, split the stereo track into left and right channels, make both mono, and delete the respective channel to isolate or remove vocals accordingly. However, it may remove more than just vocals and can leave artifacts or incomplete vocal removal, especially with backing vocals or reverb. It has fewer steps compared to the first method and removes the complete vocal removal if vocals are in a separate channel, but it is not effective for the majority of audio. Step 1. In Audacity, go to «File» > «Import» > «Audio» to select the song. Step 2. Click the down arrow on the music name. Step 3. Choose «Split Stereo to Mono«. Step 4. Click «Play» > «Solo» for each track to check if there is a solo vocal on either channel. Step 5. Click × to delete the one without the isolated vocal.

   ��Using Noise Reduction

   In Audacity, you can possibly isolate vocals by using Noise Reduction. Capture the noise profile from a vocal-removed song and apply it to the original mix to reduce noise and isolate vocals. In this way, you’ll get a clearer version of the instrument by reducing noise in the vocals but success cannot be guaranteed in all cases. Step 1. Back up the original audio track. Choose the whole track, right-click the empty space to select «Copy«, then go to «Tracks» > «Add New» > «Stereo Track» to create a new track, and «Paste» it. Step 2. Select the whole copied track and click «Effect» > «Special» > «Vocal Reduction and Isolation«. Step 3. Then choose «Effect» > «Noise Removal and Repair» > «Noise Reduction…» > «Get Noise Profile«. Step 4. Select the original track and click «Effect» > «Noise Removal and Repair» > «Noise Reduction…» > «OK«. Step 5. Click × to delete the copied track.
