TAudioConverter is a audio converter and extractor. It can convert almost any audio format to aac, ac3, mp3, flac, wav, ogg, opus or mpc. SoX is used to apply effects such as normalization, volume change etc. It can also extract audio streams from video files and encode them. Video files with more than one audio stream is supported. It is possible to run up to 8 simultaneous processes to shorten encoding time.
Levelator® adjusts the audio levels within your podcast or other audio file for variations from one speaker to the next, for example. It’s not a compressor, normalizer or limiter although it contains all three. It’s much more than those tools, and it’s much simpler to use. The UI is dirt-simple: Drag-and-drop any WAV or AIFF file onto The Leveler’s application window, and a few moments later you’ll find a new version which just sounds better.
