SUMMARY
Focus or broaden the spectral contour by narrowing or broadening the spectral peaks (formants).

The program alters the spectral envelope, i.e. the amplitude contour across the frequency spectrum. Formants are areas of higher amplitude, or  spectral peaks, while areas of relatively lower amplitude (e.g. in between harmonics) are known as spectral troughs. The program emphasizes (narrows) the peaks at the expense of the troughs (exagg <1); or conversely it can broaden the width of the formants (exagg >1) so that they are less clear and the sound becomes more fuzzy.

PARAMETERS
 exagg  Value < 1 exaggerates: narrows formants / focuses on spectral peaks; value > 1 widens formants.
The range can be misleading, as you need a lower value to exaggerate more, while a higher one will broaden.
Range: 0.001-1000, default 1. T-V
 
NOTES
Exaggerating the spectral peaks can make partials stand out individually (as different formants are prominent over time), not unlike ARPEGGIATE or TRACE. Widening the formants, and giving them less focus, in effect gives more relative prominence to the troughs and the result may be an increasingly fuzzy or noise-like sound.
