Audio Clip Editor
Introduction
This could help you edit the audio file permanently in Unity. So you don't need to use other tools to edit the original file. Also, this can help you decrease the file size by trimming unwanted segments or converting it to mono.
How To Use?
Select an audio clip to start editing. Click Save to export the edited clip and replace the original file. Click Save As to export the edited clip as a new file.
Parameters
Playback Position (in seconds)
The playback position can be controlled by dragging the icon on the waveform GUI
Start: The clip's beginning; segments before this will be trimmed.
End: Marks the clip's ending; segments after this will be trimmed.
In: The duration time of the fade-in process that will be applied.
Out: The duration time of the fade-out process that will be applied.
Delay: The duration time before the clip's beginning, silence segments will be added.
Volume
Select the tab to change the volume when exporting the clip.
Increasing the volume too much may cause clipping (distortion). Gradually increase the volume, saving frequently to listen and observe the waveform changes as you go.
Reverse
Reversing the entire clip, so it plays backward, can create a cool effect.
Convert To Mono
Converting a stereo sound to mono can decrease the file size a lot! It can help you save some memory at runtime, and decrease the size of your final build.
There are two methods available here
Downmixing: Mix the two channels together.
Left/ Right: Choose one of the channels, and abandon the other one.
