Complete tool guide

Audio Editor guide

Audio Editor provides a private, browser-based workflow for selecting and processing a clip before exporting it as an uncompressed WAV.

Your input is processed in the current browser tab and is not sent to the application server.

Why use this tool?

  • Finish a focused task without installing another app.
  • Adjust the result interactively before you copy, save, or use it.
  • Keep source data and files on this device while you work.

Common use cases

  • Removing silence from a voice memo
  • Normalizing and fading a sound effect
  • Reversing or adjusting the volume of a clip

How to use it

  1. 1

    Choose an audio file your browser can decode.

  2. 2

    Select the range on the waveform.

  3. 3

    Add volume, normalization, fades, or reversal.

  4. 4

    Preview and export the edited WAV.

Input support

Input support depends on codecs built into the current browser. Common MP3, WAV, M4A, OGG, and WebM files are often supported.

WAV output

The exported file uses uncompressed 16-bit PCM WAV. Converting higher-resolution source audio to 16-bit output can reduce precision.

Safety limits

Files and decoded PCM are limited by size and duration to protect browser memory.

Practical tips for better results

  • Use the numeric fields for fine adjustments.
  • Peak normalization targets −1 dBFS to preserve a little headroom.

Frequently asked questions

Does the Audio Editor upload my input?

No. The work happens locally in the current browser tab. Closing or refreshing the page clears temporary input unless you save the result yourself.

Can results differ in another browser or device?

They can. Browser engines, display settings, hardware capabilities, and supported file formats may affect the final result.
