WaveGain is a program that applies ReplayGain to wave files. WaveGain is an application of the ReplayGain algorithms to standard PCM wave files. Where it differs from the other applications of this principle is that the gain adjustments are applied directly to adjusting the scaling of the samples.

In other words, the option to write tags that can be read by other applications to apply the gain adjustment does not exist, so the adjustments are made directly to the data within the file.

Therefore, in the strictest meaning of the word, this process is NOT lossless. However, with the application of dithering to the output, the losses can be minimized and are, in any event, unlikely to be audible to the human ear.

So in simple terms, the program reads in wave files, analyses them, calculates and displays recommended gain adjustments (track and album), and then applies the adjustments directly to the wave data, if requested.

What's New in This Release:
With 1.2.4, all header data was copied through to the processed file including 'bext' and 'cart' chunks. As of this version, all trailers are now also copied through regardless of content. This ensures that any chunks appearing after the 'data' chunk are not lost as a result of 'wavegaining' the file. These changes have been implemented primarily to meet the needs of the broadcasting industry but will have no impact when processing regular wave files that contain the minimum chunk requirements.
