By | March 23, 2022

Whether you’re a podcaster, educator, or just someone who sends funny audio clips to your friends, audio editors can be useful. Most sound professionals tend to some audio editors. Audacity, Adobe Audition, and Avid Tools Pro are good examples.

However, what if you need to edit an audio clip but can’t install any software? With that in mind, here are the best free online audio editors.

Beautiful Audio Editor

In terms of functionality, Beautiful Audio Editor belies its status. It lets you import more than a dozen types of audio files and allows you to save your files to Google Drive. The software works directly within Chrome or Firefox, and can handle nearly an hour of audio time.

If you are familiar with Audacity, its interface should be familiar to you immediately. There’s a toolbar with toggle and export options at the top, while most of the screen contains your tracks. It supports multi-track editing and allows you to adjust the level of each track.

In addition to the basics of moving, duplicating, splitting, and speeding up audio clips, Beautiful Audio Editor has a number of effects at your disposal. This includes gain, pan, dynamic compression, reverb, and applying a low or high pass filter to your audio. You can also record directly from the interface.

Another useful feature that many similar apps don’t have is the option to create audio envelopes. This allows you to adjust the volume level of the track at various points in time. You can go from complete silence to as loud as 6 decibels higher than the actual audio level. It lets you create smooth fade-ins and fade-outs on your tracks.

  • Handle multiple tracks
  • Mute, solo and adjust individual track levels
  • Apply more than a dozen audio effects
