CHP. 7 WORKING WITH TRACKS

Choosing stereo pan types
When you pan a track using the multipurpose slider or a pan
envelope, you can choose among several pan types to determine
how ACID pans the track.
Note: When applying stereo pan types, ACID interprets a
monaural track as a stereo track with the same data in both
channels.
1. Click the multipurpose slider label and choose Pan. The pan slider appears.
2. Click the multipurpose slider label again, choose Pan from the menu, and choose a pan type from the
submenu.
• The
Add Channels pan type is most useful for panning stereo source material. This pan type makes the
stereo image appear to move as a unit between the speakers. As the fader is moved from the center to a
side, more and more of the signal from the opposite side is folded into the side you are panning towards,
until at the extreme, both channels are fed at full intensity into a single channel. This pan type uses a
linear panning curve.
• The
Balance pan type is most useful for adjusting the relative signal levels of the right and left channels
in stereo source material. In this pan type, moving from the center to a side, the opposite side starts at a
base dB level (either 0 dB, -3 dB, or -6 dB) and decays to no signal level. The signal in the side you are
panning towards starts at the base dB level (either 0 dB, -3 dB, or -6 dB) and increases to 0 dB. When
the stereo source is panned fully to one side, that side plays at 0 dB while the other side provides no
signal at all. This pan type uses a linear panning curve.
• The
Constant Power pan type is most useful for panning mono source material. As you move the fader
from side to side, this pan type creates the illusion of the source moving around the listener from one
side to the other, in a semi-circle. This pan type uses the constant-power panning curve.
You can choose a pan type as a default for all new tracks you create. For more information, see Setting default
track properties on page 178.
Using the Beatmapper
When you add a file to a project that is longer than 30 seconds, ACID’s Beatmapper Wizard starts. This
allows you to decide whether or not to add tempo information to the file.
The Beatmapper identifies a file’s downbeats and measures, allowing the file to stretch/compress in
conjunction with the project’s tempo. A file added without the Beatmapper behaves as a one-shot,
maintaining its original length regardless of the project tempo.
1. Add the file to your project. The Beatmapper Wizard starts if the file is longer than 30 seconds.
Note: You can change the file length that triggers the
Beatmapper in the
Audio tab of the Preferences dialog. For
more information, see Using the Audio tab on page 181.
2. Specify whether you want to use the Beatmapper Wizard:
• Select the
Ye s radio button and click Next to detect measures and downbeats.
• Select the
No radio button and click Finish to close the Beatmapper and add the file as a one-shot.
