One of the most common tools of the DJ trade is remixing. In some cases, there are readily available acapella versions of songs available. When there aren’t, however, it helps to know how to get vocals from a song on your own. The process for doing so is similar in most digital audio workstations (DAWs), including Logic, Audacity and, yes, Pro Tools. While the process cannot give you 100% clean vocals — no process can — it can get you close enough to use the vocals in remixes.
Open Pro Tools and insert the vocal version of the song into Track 1.
Insert an instrumental version of the song into Track 2.
Align both tracks so they are perfectly in sync.
Insert the EQ3 plug-in on the instrumental track and click the Phase Switch option. This essentially reverses the polarity of track. On the waveform, you will now see valleys where there were peaks and vice versa. The effect is a nullification of all signals in common between the two tracks. Because one track has vocals and the other doesn’t, however, the vocal will remain as it occupies a frequency range that is not affected by the phase inversion.
Bounce the project as a new track for your acapella version. From the main menu, click 'File,' then 'Bounce to Disk.' This opens a pop up box for you to choose your output settings. For this exercise, choose .wav as your file type, mono as your format, 16 bit as your resolution and 44.1 as your sample rate. This will give you a flexible CD quality rendering.
Open a new session in Pro Tools and insert your new acapella into Track 1.
Apply a noise gate to the track. From the main menu, click 'Plugin,' then click 'Expander/Gate.' Play the track while adjusting the gate and adjust the threshold to eliminate any lower volume “bleed” remaining from the instruments.
When adjusted properly, the gate will open only when the volume of the vocal exceeds the threshold you set. This allows you to clean up the track and remove any sounds occurring outside of the vocal parts. Each song is different, so you will have to rely on your ears to find the right threshold setting.

I had the exact same issue and it boiled down to an unmet dependency, however, I tried the accepted answer's solution and it did not work.What finally worked for me was installing all of the following (this is RedHat): sudo yum install curl-devel expat-devel gettext-devel openssl-devel zlib-develAfterwards, I ran the other commands as specified and it worked:./configuremakesudo make prefix=/usr/local installI pulled the list of dependencies directly from.
Tip
You won’t be able to get 100% clean vocals from a track that has the vocals mixed in. It’s like trying to get only the peanut butter from a peanut butter and jelly sandwich.
Each track is different, and some vocals will “clean up” better than others.
I have a few questions about changing the tempo and pitch of sound files in Pro Tools to make sure they all work together.
Say you have a bunch of audio files that you want to import into Pro Tools. If they are mostly 90bpm, but there are a few that are, say, 80bpm. If you set the tempo at 90bpm, drag in the files and use the TCE Trimmer on the 80bpm files to stretch them out to the same length as the 90bpm files, will they all be in the same tempo?
Is there anyway to know what tempo a sound file is in, other than a) looking at it and seeing how it matches up with a timeline, or b) listening to it?
As far as pitch goes, say you have a few sound files and you don't know how to tell what key they are in. Likewise, you can't figure out if two sound files are in the same key..what do you do? Is there any way to figure out what key the audio file is in?
Lastly, are there any plug-ins or tools with Pro Tools LE that will let you adjust the pitch of sound files so that they will work together/be in the same key?
Any help, advice, tricks, recommendations are greatly appreciated.
Thanks for your help.

| Hello. I've been selecting the pencil tool, clicking the clock button in the top, left-handed corner of the page, putting the pencil tool just under the time marker where I want the change to start, and entering a new value over by the clock. But this technique is not reliable. Also, it makes the tempo change go all the way until you insert another one. Is there and easier way to select the area where you want the tempo change to occur. Generally, I am not a fan of the drawing tools. A typer, I like the control and Alt functions. Thanks.

| 1) Put the cursor where you want and click add temp change at left of tempo area. 2) I personally map a key 'T' for me and just hit T wen I need to insert a tempo as it must be fast for tempo mapping. 3) Use my macro on the exchange to add 16 tempo marks on the next 16 measures. Search for tempo map. Just use the mouse to select and pull up or down to a tempo you want. shift + drag I believe will make it more sensitive. FYI not sure of you have done a plan to do tempo mapping but see it in this series. viewtopic.php?f=152&t=36 My Website, Free Studio One Advance Training SPECS:Win 10 64-bit, 12 Core i7: 32Gb DDR4 ram, 40' 4K monitor, StudioLive 24, Quantum, Faderport16, Central Station Plus, Sceptre 6,Temblor T10, Eris 4.5, HP60, Studio One Pro 4.0, Reaper 5.9, Sonar Platinum |
| 2) and 3) seem like they're above my head right now. The issue w/ one is that, if you change everything to the left, you may run into areas where you have tracks at a different tempo, which seems to cause any number of problems. It would be easier if you could just select two locations on the timeline and specify a tempo for that region. Any suggestions? Thanks.

| First some basics. The tempo track is global. It will change entire tempo of the song ( all tracks) Tempo is a time temporal thing. To the left of the change mark is the earlier tempo. To the right is the new tempo. The tempo to the right is the new tempo to the rest of the song or until a new tempo mark occurs. So if you wanted bar 12 - 24 to change from 95 to 100 just put a tempo mark at bar 12 set to 100 the insert another tempo change at bar 24 to change it to 95 for example. Not in front of S1 but I believe the '+' in tempo track is easiest for starters.

| Still a little confused here. You said: 'Put the cursor where you want and click add temp change at left of tempo area' I think you are saying: 1. Click where you want to occur on timeline 2. Click the clock in the top, right-hand corner 3. Enter a new value by typing a new number into the field under the clock. This technique doesn't always create tempo changes. Sometimes, you have to try to highlight the rectangular areas above the timeline blue and then enter a new value. Other times, you seemingly have to play around. Do you have more specific instructions? Or, if you work for the company, perhaps someone could make a video, or at least point me to one. I have yet to find a reliable way to change the tempo in a song. Thank you for your consideration.

| Sorry I have been on vacation for last week and only replying from and iPhone and memory. Section 8.3.1 Inserting Tempo Changes in the manual.

| That was a lot more helpful than the manual. Thanks!!! I understand it a lot better now. I'll keep playing with it? What's the (-) sign for?

| The manual is not clear. Also, as to your technique, what if you don't want to change everything to the right of the point when you change the tempo. Say I have 225 bpm from 60 to the rest of the song. I want 60 - 78 to be 215. But I want what's after 78 to stay as 225. Your technique would change all the 225 after 78 to 215.

| I think I found a workaround. In my example, you could click 78 and enter 225 as the value, effectively creating a new tempo even though it is the same as the tempo you already had.

| That's it. You write tempos from Left to Right always. So you make it whatever you want whenever you want. Example initial 100 BPM bar 20 change to 120 BPM bar 30 Change to 110 BPM bar 35 change back to 100 BPM what is (-) for ? Learn to use the bubble help it tells you what the (-) is for Also see the (?) icon in the top toolbar next to the speaker icon? Turn it on. This will give you contextual help on everything you are doing. When you have time watch my tempo mapping videos. There you will see me changing the tempo every measure or less throughout the entire song. I also go over how and when to set a track to follow or stretch or not based on what you are doing with the tempo track.

A very common ask. How can you change the tempo or the key of a CD track or any audio file (such as MP3 or wav). A common enough request – especially if you want to fit a track into another arrangement, or you want to practise along with a CD track or MP3. Why are they always so fast? Fortunately there is a very quick and easy answer whether you are on a PC, Mac or Linux. And it is FREE (but just a little bit fiddly.
Audacity is a free to download cross platform recording software which is simple to use and perfect for working with digital audio. You can directly open MP3 files and CD tracks so you can start working on them straight away.Let’s assume you are working with a CD, but you could just as easily do the same thing with an MP3 or *.wav or *.aiff file – or almost any kind of audio file.
Choose File > Open and navigate to the file or track on your CD then click on Open. The file will be converted into an Audacity project that you will be able to work on and then save. CD tracks automatically open up as 44.1 kHz stereo files. When you have done that, this is what you will see – and with a few more clicks you will have the recording at the tempo or pitch you want. Read on to find out how.
Once you have your file displaying as an audio waveform, you need to select the whole audio track.
Choose Edit > Select …. > All or click on the select tool, then click anywhere in the audio waveform and press Ctrl+A. You should see that the track is fully selected.
Once the audio track is selected, you can then access any of the following from the Effect Menu, as shown in the screenshot below.
Change The Tempo Without Affecting the Pitch
To change the tempo of an audio track without affecting the pitch in Audacity, go to Effect > Change Tempo. This option will allow you to speed up and slow down the audio track without changing the pitch. Notice there are several options to change the tempo: percent; bpm; or length. Very useful.
Tempo Tool
So when the Change Tempo dialog box pops up you can use the slider to change the tempo to a slower or faster speed. If you want to type in a specific number of seconds you’d like the audio to last you can type that in the “to” field underneath the slider. If your audio file as a specific number of beats per minute or BPM defined already, you can change the BPM instead. Experiment. There is a preview button. And if you go ahead and change the track then don’t like it, you can simply undo.
The good thing is Audacity will NOT destroy your original file, so you can experiment, and save the result as an Audacity project. Of course if you want to, you can export the result and over-write the original file if you wish. But far better to export to a newly named file, and keep the original intact.
Change the Pitch of an Audio Track without affecting Tempo
This is useful to experiment with if you want to change the key of an audio track, but leave the tempo unchanged.Useful that you can experiment by either moving up or down the required number of semitones, or go for a percent change.
The final option in Audacity for adjusting the pitch and tempo is the ‘Change Speed’ option.The thing with this option is it affects both the Tempo and the Pitch. It is unlikely you will want to do this if you are creating an audio track that you can play along to. It is more an effect you might want to use if you are doing a remix, or incorporating a sample into a project.
Saving the Result
When you have finished experimenting and are happy with your new track, there are several options for saving your work. If you choose File > Save Project As then you can save all your work in an Audacity project format which will have *.aup format. This is perfect if you just want to work within Audacity but you won’t be able to open your track in any other software.If you want to create a standard audio file in full CD quality then choose File > Export…. then pick WAV from the drop down list next to the “Save as type”.
If you want to create an MP3 to the same as above but pick MP3 Files from the drop down list. Note that Audacity uses an external utility called the Lame MP3 Encode to export MP3 files. You will need to install this in advance. You can easily find out about the Lame Encoder and details of how to install it on the Audacity site.
The above, once you had done it a couple of times, will take you just a few minutes. Phew no more despair as you try and keep up with your favourite backing tracks while you are learning something new.
Adjust Tempo AND Remove Vocals
One of the reasons you might want to change either the tempo or the pitch of an audio track is so that you can play along with it. Sort of like a Karaoke. So you might want to combine the above with removing the vocals from your song track. I would recommend removing vocals first, then playing with the tempo and pitch as above.
Useful Equipment For Playing and Singing Along With Audio Tracks
Once you have the audio track set up to your liking, then think about using a USB Microphone (with headphone port) or and Audio Interface … so you can hear both yourself and the track combinedThe Tempo Track Editor provides an overview of the project tempo settings. It allows you to add and edit tempo events.
