How to Use Time Stretch in Beatmaking: A Comprehensive Guide

Time stretch is an essential tool in modern music production, allowing producers to manipulate the tempo and duration of audio samples while preserving their pitch. It has become increasingly popular in beatmaking, as it enables producers to create unique and innovative sounds that push the boundaries of musical creativity. In this comprehensive guide, we will delve into the world of time stretch and provide a step-by-step tutorial on how to use it effectively in beatmaking. With over 1500 words, this article will serve as a valuable resource for both beginners and experienced producers looking to expand their knowledge and skills in the art of beatmaking.

I. Understanding Time Stretch

Before diving into the practical aspects of time stretch, it’s important to understand the concept and how it works. Time stretching is the process of altering the duration of an audio sample without affecting its pitch or timbre. This is achieved by analyzing the sample’s waveform and creating a new version of the sample with a different tempo, all while maintaining its original pitch.

The two primary types of time stretch algorithms are:

  1. Granular: This method involves breaking down the audio sample into small grains or segments, and then reassembling them in a manner that changes the duration of the sample. Granular time stretch can produce smooth results, but may introduce artifacts at extreme settings.
  2. Phase Vocoding: This technique involves transforming the audio sample into the frequency domain using the Fast Fourier Transform (FFT) and then modifying the timing information before converting it back into the time domain. Phase vocoding provides higher-quality results, especially when dealing with complex sounds and extreme time-stretching.

II. Applications of Time Stretch in Beatmaking

Time stretch is a versatile tool in beatmaking, offering several creative applications, including:

  1. Matching Tempos: When working with multiple samples or loops, time stretching can be used to synchronize their tempos and create a cohesive beat.
  2. Remixing: Time stretch allows producers to alter the tempo of a song or sample, providing new creative possibilities for remixes and mashups.
  3. Sound Design: Time stretching can be used to create unique sound textures, such as slowing down a drum loop to create a dramatic, cinematic effect.
  4. Transition Effects: Time stretching can be applied to create smooth transitions between sections of a song or between different samples.
  5. Sample Manipulation: Time stretch can be used to create new variations of a sample, providing an endless source of inspiration for beatmakers.

III. Time Stretch in Popular Digital Audio Workstations (DAWs)

Most DAWs come with built-in time stretch functionality, though the specific tools and processes may differ slightly between programs. Here’s a brief overview of how to use time stretch in some popular DAWs:

  1. Ableton Live: In Live, time stretching can be done using the Warp feature. To use this feature, double-click on the audio clip you want to stretch, enable the Warp button, and adjust the tempo using the Seg. BPM field.
  2. FL Studio: In FL Studio, time stretching can be done using the Time Stretch tool in the Sampler Channel Settings window. To access this, click on the sample you want to stretch, and then adjust the Time knob to stretch or compress the sample.
  3. Logic Pro: In Logic, time stretching can be done using the Flex Time feature. To enable Flex Time, click on the Flex button in the toolbar and choose the appropriate Flex mode. Then, click and drag the audio region’s edges to stretch or compress the sample.
  4. Pro Tools: In Pro Tools, time stretching can be done using the Elastic Audio feature. To enable Elastic Audio, right-click on the audio track you want to stretch, choose Elastic Audio, and then select the appropriate Elastic Audio plugin. Next, enable the Warp mode by clicking on the Warp icon in the Edit window and adjust the audio region’s edges to stretch or compress the sample.
  5. Cubase: In Cubase, time stretching can be done using the AudioWarp feature. To access AudioWarp, double-click on the audio clip you want to stretch and open the Sample Editor. Then, activate the AudioWarp tab, enable the Free Warp mode, and adjust the audio clip’s edges to stretch or compress the sample.

IV. Step-by-Step Guide to Using Time Stretch in Beatmaking

Now that we have a basic understanding of time stretch and its applications, let’s dive into a step-by-step tutorial on how to use it in beatmaking.

Step 1: Import the Audio Sample

First, import the audio sample you want to work with into your DAW. This can be a drum loop, melodic sample, or even a vocal sample.

Step 2: Determine the Sample’s Original Tempo

Before you can time stretch your sample, you need to determine its original tempo. This can be done using your DAW’s built-in tools, such as a tap tempo function or by manually counting the beats per minute (BPM).

Step 3: Set the Project Tempo

Now that you know the sample’s original tempo, set your DAW’s project tempo to match. This ensures that your time-stretched sample will be synchronized with other elements in your beat.

Step 4: Apply Time Stretch to the Sample

Using the time stretch functionality in your DAW, adjust the duration of your audio sample to match the desired tempo. Remember to use the appropriate time stretch algorithm for the best results, and be mindful of potential artifacts or audio quality degradation.

Step 5: Fine-Tune the Time-Stretched Sample

After applying time stretch, listen to the sample and make any necessary adjustments. This may include fixing any artifacts or glitches, adjusting the sample’s start and end points, or applying additional processing, such as EQ or compression.

Step 6: Incorporate the Time-Stretched Sample into Your Beat

Now that your sample has been time-stretched, you can incorporate it into your beat. This may involve layering it with other samples, adding effects, or creating a new pattern using your time-stretched sample as a foundation.

V. Tips for Effective Time Stretching

  1. Experiment with Different Algorithms: Different time stretch algorithms can produce varying results, so don’t be afraid to experiment to find the best fit for your sample.
  2. Avoid Extreme Time Stretching: While time stretch can produce interesting results, extreme settings can lead to artifacts and poor audio quality. Use moderation and consider alternative techniques, such as resampling or pitch shifting, for more drastic tempo changes.
  3. Use High-Quality Samples: Time stretching can sometimes introduce artifacts, so starting with high-quality samples can help minimize potential issues.
  4. Consider Additional Processing: Time stretching may alter the character of your sample, so consider using additional processing, such as EQ, compression, or reverb, to enhance the sound and help it blend with the rest of your beat.


Time stretch is an invaluable tool for beatmakers, providing countless creative possibilities and applications. By understanding the fundamentals of time stretch and following this comprehensive guide, you’ll be well-equipped to incorporate time stretch into your beatmaking workflow and create unique, captivating sounds.
