Speeding Up Audio in FL Studio Is Very Easy + (4 Tips)

Written By : Andrew Siemon

Because of loops and samples, music production is easier, more interesting, and more engaging these days. If you want to use them, you’ll need to control the speed. This is pretty easy in FL Studio.

To speed up audio in FL Studio, double-click the audio clip to open the Channel Settings window and then choose “Stretch Pro” from the Modes list. Resize the audio to the left to speed it up. Using this setting instead of just “Stretch” will change the clip’s tempo without modifying the pitch.

The Easiest Way to Speed Up Audio in FL Studio

This method is the easiest way of speeding up audio in FL Studio, but there are other ways too.
(If you’re on mobile, turn your phone sideways for a closer look)

The bolded snippet at the start of the article is the TLDR of how to do it, whereas the GIF above is a video walk-through of the same process. The following section down below is a guided walkthrough of the same process as well but with pictures and additional explanation.

1) Double-click on the Audio Clip

Click the Audio Clip
You can open up the sampler in a number of ways, however, I prefer to just double-click on the audio clip.

2) Choose “Stretch Pro” in the “Mode” Menu

Choose Stretch Pro
Stretch Pro will allow you to make changes to the clip’s tempo without affecting its speed.

I’ve read elsewhere the “Stretch” works, but that wasn’t the case for me. I had to use “Stretch Pro” in order to stretch the sample without altering the pitch.

3) Use Your Cursor To Drag and Resize the Audio Clip

Resize the clip as shown here until you’ve sped up in the way that you want.

And that’s pretty much it. FL Studio makes speeding up and slowing down audio in their interface incredibly easy and intuitive. I still like GarageBand, but it’s harder on that platform for sure (my guide).

3 Other Ways of Speeding Up Audio in FL Studio

1) Stretching the Audio with the “Stretch” Button

This method works best for audio samples with clear transients or distinct beats that can be used as a reference to the metronome or drums when stretching the audio.

A) Load Your Audio Into The Project

Drag and drop your file into the Playlist as shown here. There are other ways to do it too which I’ve discussed in my other post.

Begin by loading up the audio you need to work on into the playlist of the project (if you haven’t already). Locate the file path on your computer, then drag and drop it into the playlist.

You can also load samples from FL Studio’s browser by dragging and dropping them from the browser to the playlist.

B) Find The Clip Focus Pane On The Playlist

Find the Clip Focus section of the playlist. This section gives options for editing either audio, pattern, or automation clips in unique ways. You will find it at the top left corner of the playlist, as highlighted in the picture above.

C) Select Audio Focus

How to Speed Up Audio in FL Studio; Select Audio Focus

To focus on audio clips, you have to select the option for audio. It is the button that is shaped as a waveform. Hovering over this button with your mouse gives a brief description of what it does in the hint panel.

Under audio focus, you will find two options. “z-cross” and “stretch”. Z-cross is useful when slicing audio in the playlist, to make sure that you slice on an approximately “zero” point (where the volume of the audio is zero). This is not useful for speeding up audio.

The Important and useful option for speeding up audio is the “stretch” option. It helps us increase or decrease the size of audio clips when we resize them. Instead of cropping or elongating the audio, it speeds it up or slows it down.

D) Enable Stretching Of Audio When Resizing Audio Clips

Enable stretch by clicking on the checkbox. Don’t forget to uncheck it once you are done with speeding up your audio so that it will not alter your future projects. Also, have a look at the hint panel when you hover your mouse over it. You’ll see exactly what it does.

E) Resize Your Audio

How to Speed Up Audio in FL Studio; Resize Your Audio

The next step is to resize your audio. To speed it up, drag it to the left. Dragging it to the right will slow it down.

As you drag it to the right, put on the metronome and take note of when the audio has been synced to your BPM. If the audio is a perfectly timed loop/sample (probably 4 or 8 bars) just resize it to the point where it fits.

One thing to note is that stretching audio changes its pitch also, so don’t be confused when you notice the pitch of your audio has been changed. To correct this, you need to change the stretch mode in the sampler.

F) Open The Sampler

How to Speed Up Audio in FL Studio; Open the Sampler

To open the sampler, simply double-click on the audio clip in the playlist. This opens up the sampler. Another way to open the sampler is from the channel rack. On the channel rack, open the sampler by clicking on the channel containing the audio and the sampler opens.

G) Under the Time Stretching Tab, Change The Mode To Stretch

Once you are in the sampler window, locate the Time Stretching tab. Under mode, open the options and select Stretch. Selecting stretch corrects the pitch change that occurred when you resized the audio clip.

2) Using Time Stretch In The Sampler

In the Sampler, you will see a section called Time Stretching. Using the Sampler for speeding up audio works in a similar way. The difference is in the way it is done. It is preferably done from the playlist.

This method speeds up the audio and changes the pitch at the same time. This means, you still have to open the sampler and change the mode to stretch to correct the change in pitch.

A) Load Your Audio Into The Project

To load your audio into the project from your computer, just drag it and drop it where you want to be on the playlist. Also, loading up audio from the FL browser is done by dragging and dropping.

B) Open The Sampler

How to Speed Up Audio in FL Studio; Open the Sampler

Open the Sampler to begin the process of time stretch. To open the sampler from the playlist, double-click on the audio clip. From the channel rack, click the audio channel and the sampler comes up.

C) Find The Time Stretching Tab

How to Speed Up Audio in FL Studio; Find the Time Stretching Tab

You will see the Time Stretching tab at the top right side of the sampler window. It has 3 knobs and a Mode drop-down where you can select different methods for time stretching. From left to right, the buttons are Pitch, Time Stretch Multiplicator (MUL), and Time.

Adjusting the Pitch button changes the pitch without affecting the speed of the audio. MUL adds a multiplier effect to the Time Stretching. Time determines how long or short the audio will be.

D) Move The Time Knob

How to Speed Up Audio in FL Studio; Move the Time Knob

The time knob in its default position is the original length/speed of the audio. Moving the knob upwards(clockwise) will shorten the audio (increase the speed).

When turning the knob, take a look at the hint panel and you’ll notice the tempo change as you turn the knob. The hint shows the tempo of the audio as you stretch it.

The more you turn it, the higher the tempo becomes (This does not mean the audio gets faster). So, If you know the tempo of the audio, turn the time knob until you get to the tempo of your audio.

If the audio did not come with its tempo info, then look at the playlist as you stretch. Make sure the audio transients align with the grid of the playlist. Then listen to it with the metronome on to make sure you are on time.

3) Changing The Project Tempo

The third method to be considered is changing the tempo. I know you are probably thinking that this should be the most obvious way. This method is usually a last resort because changing the tempo affects the whole project, not just a single audio clip, It is nonetheless important.

To change the speed of your project you need to create a tempo automation. This automation will cause a rise in the tempo at the point you put it. You can create automation clips following the steps below.

A) Load Your Audio Into The Project

How to Speed Up Audio in FL Studio; Load Your Audio into the Project
Open the project you want to work on and load your audio into the project.

B) Find The Tempo Button

How to Speed Up Audio in FL Studio; Find the Tempo Button

The tempo button is located in the toolbar beside the play/stop and record buttons. As highlighted above, you can see the tempo of the project in BPM.

This is where changes can be made to the tempo information of the whole project. There’s no tempo button for individual audio.

C) Move The Tempo Button

How to Speed Up Audio in FL Studio; Move the Tempo Button

To change the tempo of a project, click and hold the tempo button, and drag it up or down. Dragging it up will increase the tempo and dragging it down will decrease it.

To increase the speed of the project, then drag this button up to your desired speed. To create a rise in tempo as the song progresses, you need to create an automation clip for the tempo.

D) Create A Tempo Automation

How to Speed Up Audio in FL Studio; Create a Tempo Automation

Create an automation clip for the tempo by firstly right-clicking the tempo button. From the pop-up menu select “Create automation clip”. It is important to note that when you create an automation clip this way, the automation spans the whole project.

To create automation for a specific area only, select that area from the audio timeline on the track menu (using Ctrl (Cmd) + drag), before creating the automation clip.

E) Raise The Tempo

To achieve this tempo automation increase, move the start point of the automation clip to where you want the tempo increase to start. Then drag the point at the other end of the automation clip up to your desired level. You may have to listen over and over till you get the desired result.

Important Things to Note About Changing the Tempo in FL Studio

1) Changing the Tempo Gradually Is Done Differently

If you’re interested in speeding up audio as the song progresses (for musical dynamism or as an effect), you need to create a tempo automation in the project that increases the tempo as the song progresses.
