Volume Balancer is primarily intended for use as a final step before burning a compilation CD from a variety of sources. Note that Volume Balancer works only on CD-format WAV files (ie. 44.1kHz, 16-bit, stereo). It does not work on MP3 files; if you wish to balance the loudness of these, it is necessary to convert them to WAV files first.
As many people have found to their frustration, simple normalization of the peak levels of WAV files does not make them sound equally loud. Perceived loudness is also influenced by the dynamic range of the file. To balance the loudness of a set of WAV files requires experimentation with varying degrees of dynamic range compression, and this can be very tedious. Volume Balancer automates this process and is exceptionally easy to use.
