Trim and export a section of an audio file

Updated

What is the Audio Trimmer?

Quickly and precisely trim your audio files right in your browser. Our Audio Trimmer lets you load any common audio format, visualize the waveform, and select the exact segment you want to keep.

Whether you are editing a podcast, creating a ringtone, or removing dead air from a voice recording, this tool provides professional-grade controls without the learning curve. Add fade in and fade out effects, adjust gain, and export your clip as a high-quality WAV file.

Best of all, everything happens locally on your device. Your files are never uploaded to a server, ensuring complete privacy and instant processing speeds.

How it works

  1. Upload Your Audio: Drag and drop your audio file (MP3, WAV, OGG, M4A, FLAC) into the dropzone. The tool processes the file locally, so no internet connection is required for the actual editing.
  2. Visualize the Waveform: Once loaded, an interactive waveform displays your audio's dynamics. You can zoom in for micro-edits or zoom out to see the entire file at a glance.
  3. Select Your Segment: Click and drag on the waveform to create a selection. Grab the edge handles to fine-tune the start and end points. You can also use the arrow keys on your keyboard for frame-accurate adjustments.
  4. Apply Effects: Add a professional touch by applying fade in or fade out effects to smooth transitions. Use the gain slider to boost or lower the volume of your selection.
  5. Preview and Export: Play the selection to verify your cuts. Once satisfied, configure your export settings (bit depth, sample rate, channels) and export the result as a pristine WAV file.

Frequently asked questions

Is my audio file uploaded to a server?

No. This audio trimmer runs entirely in your browser. Your files are processed locally on your device, which means they are never uploaded, stored, or shared on any external server. This ensures maximum privacy and security.

What audio formats can I import?

You can import any audio format that your browser natively supports via the Web Audio API. This typically includes MP3, WAV, OGG, M4A, and FLAC. The exact formats supported may vary slightly depending on whether you are using Chrome, Firefox, Safari, or Edge.

What format is the exported file in?

Currently, the tool exports your trimmed audio as a WAV file. WAV is a lossless format, ensuring you get the highest possible audio quality. You can customize the bit depth (8, 16, 24, or 32-bit), sample rate, and channel configuration (mono or stereo) before exporting.

How do I make precise cuts?

For frame-accurate editing, simply click on the waveform to select it, and use your keyboard arrow keys. The Left and Right arrows nudge the start time, while the Up and Down arrows adjust the end time. Hold Shift while pressing the arrow keys to move in larger increments (1 second).

Can I add fade in and fade out effects?

Yes. Below the waveform, you will find sliders for both Fade In and Fade Out. You can adjust these to smoothly ramp the volume up at the beginning of your selection and down at the end, preventing sudden clicks or pops in your final audio file.
