Volt is a surprisingly powerful, if unconventional audio editor for adjusting the volume difference between sound files. It helps you make adjustments while listening to your ears, rather than processing them mechanically. It can handle everything from long ones like music to short ones such as sound effects and voices. After adjusting the volume, you can output the adjusted value in CSV format or *bounce with the adjustment applied. Volt can import all the major file types: WAVE, AIFF, AAC, MP3, Ogg Vorbis, WMA, and CDA (cd audio). Volt requires Microsoft .NET Framework 4.0.

Volt main features:
Preview playback that allows you to specify the playback range, playback position, loop, etc.
Quick volume adjustment while comparing with the reference
Region editing with partial volume change
Background color change due to loudness value
Uniformity of loudness value
Bounce output with volume adjustment applied (supports multiple formats)
CSV output of volume adjustment value
Adjustment results can be saved as a list. High-speed recovery by waveform cache when reloading
Supports undo and redo
Control from command line

*The following items are required for bounce output of MP3, AAC, and Ogg Vorbis.
MP3: lame.exe
AAC: neroAacEnc.exe
Ogg Vorbis: oggenc2.exe
