With this multiplatform tool, you can edit and analyze any audio track. Just select the parts you want to change with your mouse and apply effects or corrections from the control bar at the top of the interface.
With Ocenaudio you can also play the files, remove fragments to add effects, correct minor errors (such as noise), apply transitions, save the new changes as a separate file, or change the format in which the file is saved.
Once you drag an audio track to the interface window, you'll see a graph of sound waves and can then select, cut, copy, or edit as you wish.
You can also work with two clips simultaneously, one at the top and the other at the bottom.
In short, Oceanaudio is a totally free way to edit your audio files.
