USING ADOBE AUDITION 55 Editing audio files • Neutral Light is flat up to 14 kHz, ramps noise up to a maximum at 17kHz, and is again flat at higher frequencies. Background noise sounds the same as it does without noise shaping but is about 11dB quieter. Heavy is flat up to 15.5kHz, placing all dithering noise above 16kHz (or wherever you specify the crossover). Sensitive ears may hear a high pitched ringing if the crossover is too low. If converting 48 or 96 kHz audio, however, the crossover can be placed well above 20 kHz. Choose a Neutral shape to avoid sonically coloring background hiss. Note, however, that hiss will sound louder than with other shapes. • U-Shaped Shallow is mostly flat from 2 kHz up to 14 kHz but gets louder as audio approaches 0 Hz because low frequencies are much less audible. Medium places a little more noise in the highs above 9 kHz, allowing for lower noise below that frequency. Deep increases noise above 9 kHz even more, but also lowers it much more in the 2-6 kHz range. • Weighted Light attempts to match how the ear perceives low-level sounds by reducing noise more in the 2-6 kHz range and raising it in the 10-14 kHz range. At high volumes, hiss may be more noticeable. Heavy more evenly reduces the most sensitive 2-6KHz range at the expense of more noise above 8kHz. Crossover Specifies the frequency above which noise shaping will occur. Strength Specify the maximum amplitude of noise added to any one frequency. Adaptive Mode Varies the distribution of noise across frequencies.

Background noise sounds the same as it does without noise shaping but is about 11dB quieter.
Heavy is flat up to 15.5kHz, placing all dithering noise above 16kHz (or wherever you specify the crossover). Sensitive
ears may hear a high pitched ringing if the crossover is too low. If converting 48 or 96 kHz audio, however, the
