Pan/Expand controls
The following controls are located in the Pan/Expand dialog.
Control Description
Process mode The Process mode drop-down list contains the following options:
Pan (preserve stereo separation) Applies the pan effect without mixing the
channels, thereby simulating the spectral positioning of stereo recordings.
Pan (mix channels before panning) Mixes the left and right channels prior to
applying panning effects.
Stereo expand Allows you to contract or expand the image of stereo audio from
dead center (mono) to completely panned wide (no center channel).
Mix mid-side (MS) recording to left and right channels Simulates a recording
technique in which one microphone is pointed directly at the source and used to
record the center (mid) channel, and a second microphone is pointed 90 degrees
away from the source (side) and used to record the stereo image.
For proper playback on most systems, MS recordings must be converted to
standard left/right orientation.
To convert an MS-recorded track to a left/right track, first ensure that the center
channel is in the left track and the side channel on the right. The MS mix function is
then used to set the width of the stereo image for the converted track.
Output gain Determines the amount of gain applied to the signal following pan/expand
processing.
Show wave The Show wave drop-down list provides several settings for drawing the current
selection’s waveform on the envelope graph. This function is available only for small
selections.
Reset Envelope Clicking the Reset Envelope button clears all but the two original envelope points.
•For the Pan modes, these two points prevent unintended panning.
•For the Stereo expand and Mix Mid-Side modes, these two points prevent
unintended expansion.
Resample
The Resample command allows you to change the sampling rate of a file without altering its pitch or duration.
Resampling to a lower sample rate results in less frequent samples and a decreased file size, but adds aliasing noise to the audio. For
more information, see Apply an anti-alias filter during resample on page 190.
Resampling to a higher sample rate results in extra samples being created through interpolation and an increased file size. Like
increasing bit depth, up-sampling does not improve the quality of an audio file, but permits subsequent audio processing to be
performed with greater precision.
