How to Change Audio Speed and Pitch in NeonWaves

Ever needed to slow down a recording without making the voice sound deeper? Or speed up a clip without turning it into a chipmunk? NeonWaves makes both possible in just a few clicks.

In this guide, we’ll walk through how to change the speed, length, or pitch of your audio using the Stretch tool in NeonWaves and explain exactly when to use each of its three modes.

What Is the Stretch Tool?

The Stretch tool is where NeonWaves handles speed and pitch changes. You’ll find it by selecting the audio you want to edit and opening Transform > Time > Stretch from the toolset.

Inside, you get three distinct modes. Each one changes your audio in a different way, so picking the right one matters.

Three Ways to Change Speed and Pitch

1. Time Stretch: Change Speed, Keep Pitch

Time Stretch makes your audio faster or slower while keeping the original pitch intact. Voices stay natural — no chipmunk effect, no slowed-down monster voice.

This mode is ideal when you need to:

• Shorten a podcast episode to fit a time slot
• Slow down a tutorial for clarity
• Adjust a voiceover to match video length

Speed up or slow down audio while preserving the original pitch

2. Pitch Shift: Change Pitch, Keep the Speed

Pitch Shift works the opposite way. It raises or lowers the pitch of your audio while keeping the speed and duration exactly the same.

Use Pitch Shift when you want to:

• Adjust vocal tone without affecting timing
• Create harmonies or vocal variations
• Fine-tune a recording that’s slightly off-key

Raise or lower audio pitch without changing playback speed or duration

3. Resample: Change Speed and Pitch Together

Resample changes speed and pitch at the same time. As the audio plays faster, the pitch rises. As it slows, the pitch drops.

This mode suits creative or retro-style effects where a natural, linked change in speed and pitch is exactly what you want.

Understanding the Ratio: Above and Below 100%

Each mode uses a ratio to control the amount of change:

• Below 100% slows down and lengthens the audio.
• Above 100% speeds up and shortens the audio.

You can use the built-in presets for quick results, or enter a custom ratio for precise control.

Whether you’re trimming a podcast, tuning a vocal take, or experimenting with sound design, NeonWaves gives you precise control over speed and pitch – all from one simple panel.
