<br>
When an analogue [audio] signal is converted to the digital domain, the signal is sampled at a fixed rate<br>
(e.g. 44100 samples per second) and each "sample" value is stored with a fixed number of bits (e.g. 16 or 24<br>
bits per sample). Consequently [uncompressed] digital audio is represented as a sequence of binary sample<br>

<br>
The "equalization" modes control how the normalization filter will deal with multi-channel input files, i.e.<br>
everything that is not Mono. The "Peak Level" mode will normalize each channel according to its highest peak<br>
(maximum sample value). This means that channels with a lower maximum sample value will be amplified stronger<br>
than channels with a higher maximum sample value. Still all samples in a channel will be amplified by the<br>
same factor, so dynamic range compression is NOT done. The "RMS Level" mode works similar to the previous<br>
mode, but the channels are amplified according to their peak RMS level (maximum energy), instead of their<br>
maximum sample value. This may be used to correct stereo imbalance caused by an imperfect record turntable<br>
cartridge. Last but not least, the "None" mode will not euqalize the channels at all, i.e. all channles will<br>
by amplified by the same factor. In the last mode, the highest peak of all(!) channels is used as threshold.<br>

WARNING: The "None" mode appears to be broken with more than two channels! This is a bug in SoX.<br><br>
