This multiplatform tool can edit and analyze any audio track very quickly and easily. Just select the parts you need to modify with the mouse and apply effects or corrections from the control bar at the top of the interface.
With Ocenaudio, you can perform very specific tasks such as playing files, removing fragments, adding effects, correcting minor sound errors (such as background noise), applying transitions, and recording the new changes as a separate file or changing the audio format of what you want to edit.
The program interface shows a window where you can drag the audio and, that done, it displays a graph of soundwaves that you can select, cut, copy, or edit directly. And you can also work with two clips simultaneously, in which case one will appear at the top and the other at the bottom.
In short, Oceanaudio is a completely free solution for editing your audio files.
