ADOBE AUDITION 1.5
User Guide
Different curves result in different types of background noise. The type of curve to use
depends on the source audio, final sample rate, and bit depth. By introducing noise
shaping, you may be able to get away with a lower dither depths to reduce the overall
background noise level, without introducing a lot of unwanted harmonic noise.
Note: In general, there are no really good noise shaping curves for audio at 32 kHz or lower.
With audio at those sampling frequencies, try the different curves to see if they help, and just
choose the one that sounds the best.
Converting multiple files to the same sample rate
If you need to make the same conversion on multiple files, you can save time by creating
a sample rate conversion preset.
To create a sample rate conversion preset:
1 Choose Edit > Convert Sample Type. Alternatively, click the Convert Sample Type
button in the toolbar.
2 Adjust the settings as desired.
3 Click Save As, type a name for the preset, and click OK.
