Envelope tab controls
The following sections describe all controls located on the Envelope tab.
Control | Description |
Impulse | This control is identical to the Impulse |
| view the envelope graphs for the specified impulse file. For more information, see Impulse on |
| |
|
|
Dry Out | This control is identical to the Dry Out fader on the General tab. For more information, see Dry |
| |
|
|
Wet Out | This control is identical to the Wet Out fader on the General tab. For more information, see Wet |
| |
|
|
Apply envelope and limit decay | This control is identical to the Apply envelope and limit decay check box on the General tab. |
| For more information, see Apply envelope and limit decay to (seconds) on page 216. |
|
|
Envelope Graph | Selecting the Apply envelope and limit decay check box turns on the Envelope Graph. You |
| can use the envelope graph to decrease the length of the specified impulse file, which |
| consequently decreases the reverberation decay time and processing time. You can also use |
| the envelope graph to apply fades to the specified impulse file. |
| The horizontal axis of the graph represents the time of the impulse file and the vertical axis |
| represents peak amplitude in dB. Specifying an impulse file from the Impulse |
| automatically displays its envelope in the graph. |
| Note: If the impulse file is greater than 6 seconds in length, it does not display in the |
| envelope graph. |
|
|
Envelope points | Envelope points are used in the envelope graph to specify a fade curve. The fade amount can |
| vary from 0% to 100%. You can create, delete, and arrange envelope points just as you can in all |
| of the Sound Forge envelope graphs. For more information, see Envelope graphs on page 49. |
| Note: The fade value at any point in a curve does not use the same vertical logarithmic (dB) |
| scale used for displaying the impulse file. |
|
|
Reset | Clicking this button resets the envelope points to 100%, indicating no fade. |
|
|
Package Impulse into Preset | Clicking this button creates a link between the current preset and the selected impulse file, |
| along with encoding the impulse information. You can use the Preset Manager to share presets |
| and the accompanying impulse files between computers without losing information. For more |

Adjusting the impulse length
Drag the vertical Envelope Endpoint line to the desired location. The Envelope Endpoint is repositioned and the length of the impulse is adjusted.
