How to Speed Up Audio without Changing Pitch?

Perhaps due to the need for efficiency or usage habits, you may want to speed up audio files. However, accelerating the file will lead to distortion. Voices and sounds can become mechanical. And the pitch will get higher.

Are there any apps and methods to adjust audio without affecting pitch? Yes, of course. Audio editor software, online audio speed changers, and professional digital audio workstations (DAWs) are helpful tools to speed up audio.

If you just want to make simple adjustments, you’d better use audio editors or online tools. But, if you require high quality files, using DAWs will be an optimal choice.

Read on and see how to use them.

Method 1: Use Audio Editor to Speed up Audio without Changing Pitch

Using audio editor software is the simplest way. Quite a lot of editing tools are able to change the speed, for example, using the feature of rate change. Here is a guide.

Step 1.Drag the file to the audio editing software.

Here, we use an MP3 file to demonstrate the feature. Now, drag the file to Kingshiper Audio Editor once you installed and opened it.

Step 2.Select a time range in the audio track.

As the MP3 waveform is visualized, you can choose the range that you want to speed up. Click the red buttons placed on the left and right sides and drag them when a black arrow shows up.

For a more precise scope, please use ‘Start Time’ and ‘End Time’ to enter specific figures.

Step 3.Click Rate Change to speed up the audio file.

You will see a pop-up window after clicking ‘Rate Change’ for further adjustments.

In ‘Duration’, Kingshiper will automatically calculate the time span of your selected audio clip.

To change the speed, you can drag the slider. The left means slow speed while the right side is to accelerate.

If you want a dedicated speed control, then you should use the number spinner below.

Step 4.Tick ‘High Quality Stretching’ to change speed without affecting pitch.

You need to tick the checkbox ‘Use high quality stretching’ before implementing the rate change.

This is the feature that allows you to speed up audio but not change its pitch.

Step 5.Click OK to proceed with the adjustment.

Step 6.Play the audio and check the effect, then export it.

Click the play button to see if the MP3 meets your need. Then click ‘Export’ to save the file.

Kingshiper Audio Editor is an easy-to-use and powerful software. It’s free to install, and all editing features are cost-free.

Supported input audio formats: mp3, mp2, ogg, flac, m4a, wav, amr, ac3, wma, aiff, aifc, caf, m4r, aac, wv, mmf, ape, amr, au, voc, 3gp, avi, flv, mkv, mov, mp4, mpg, swf, wmv, 3gpp

Method 2: Use Online Audio Speed Changer to Accelerate Audio

Step 1. Go to AudioSpeedChanger.

Step 2. Click ‘Choose File’ and wait for uploading.

Step 3. Remain zero in ‘Pitch change.’ This will make the key unchanged.

Step 4. Set a value in ‘Playback speed.’ You should set it to more than 100% so that the playback speed will increase.

Step 5. Click ‘Covert now’ and download the audio.

Method 3:Use Pro Digital Audio Workstations to Speed up Audio without Changing Pitch

Adobe Audition, an industry-standard Digital Audio Workstation, supports Windows and macOS and is excellent for editing podcasts and music. If you need high-quality speed-up audio files, it’s the tool.

Step 1.Download and install Audition.

Here is a quick access to download the software.

Step 2.Open the audio file in ‘Files > Open file’.

You can see the audio has become a visualized sound wave.

Step 3.Use ‘Time and Pitch’ feature to speed up audio.

Find the Time and Pitch feature in Effects. Then click Stretch and Pitch (Process).

Now set a value in ‘Stretch.’ This is the place for you to adjust the speed of the audio.

As for keeping the pitch unchanged, you need to set the ‘Pitch Shift’ as zero.

Click ‘Apply’ to implement the operation.

Step 4.Preview the adjustment.

Click ‘Play’ to see if the audio file is edited as you want.

Step 5.Export the speed-up audio file.

Click ‘File’ > ‘Export’ > ‘File’ to export the audio. You can rename it, choose a location, the output format, format settings, and others as well.

Conclusion

Using pro DAWs can have more granular control on speed and pitch changes of audio, and also the advanced waveform editing. This helps to make high-quality audio for specific usages, such as commercial uses and ads.

But, if you just want personal use, like learning, you don’t have to make it complicated. Using audio editor software and online tools is enough.
