Specifies the number of milliseconds in each RMS window. A selected range contains a series of such

windows, which Adobe Audition averages to calculate the Minimum RMS and Maximum RMS values. To achieve the
most accurate RMS values, use wide windows for audio with a wide dynamic range, and narrow windows for audio
with a narrow dynamic range.

Converting sample types

Hear a file in a different sample rate
The Interpret Sample Rate command lets you hear how an audio file sounds at a different sample rate. (See
"Understanding sample
rate" on page 5.) This command helps you identify files that specify an incorrect rate in the
file header. To then permanently convert the sample rate, choose Edit > Convert Sample Type.
In the Waveform Editor, choose Edit > Interpret Sample Rate.
1
Enter a sample rate in the text box, or choose a common sample rate from the list.
2
Note: Although you can work with sample rates ranging from 6000 to 192,000 Hz in Adobe Audition, your sound card may
not be capable of playing all rates properly. To determine supported sample rates, consult the documentation for the card.
Convert the sample rate of a file
The sample rate of a file determines the frequency range of the waveform. When converting the sample rate, keep in
mind that most sound cards support only certain sample rates.
In the Waveform Editor, choose Edit > Convert Sample Type.
1
To quickly access the Convert Sample Type dialog box, double-click the Sample Type section of the status bar. (See
"Display the status
bar" on page 16.)
Select a rate from the Sample Rate list, or enter a custom rate in the text box.
2
3
In the Advanced section, drag the Quality slider to adjust the quality of the sampling conversion.
Higher values retain more high frequencies, but the conversion takes longer. Lower values require less processing time
but reduce high frequencies.
Use higher Quality values whenever you downsample a high rate to a low rate. When upsampling, higher values have
little effect.
For the best results, select Pre/Post Filter to prevent aliasing noise.
4
Convert a waveform between surround, stereo, and mono
The Convert Sample Type command is the quickest way to convert a waveform to a different number of channels.
In the Waveform Editor, choose Edit > Convert Sample Type.
1
2
From the Channels menu, select Mono, Stereo, or 5.1.
