Description

Buffers to Process per Second

Specify how many playback buffers are processed per second. A larger number may increase real-time playback reliability.

Total Playback Buffers

Specify the number of playback buffers. A larger number may increase real-time playback reliability.

Do Not Allow In-Place Buffer Size Increases

Select this check box only if a plug-in fails to correctly handle buffer size information.

When this check box is selected, the available data size and the actual data buffer size are forced to be equal. Plug-ins based on Microsoft's original Gargle Filter example may require this option to be enabled.

Use Plug-In's Requested Minimum Buffer Size

Select this check box only if a DirectX plug-in fails to connect and process audio. Some plug-ins may only work with specific buffer sizes.

Crossfade Edges

Select this check box to crossfade the edges of the processed and unprocessed audio at the start and end of the current selection. Crossfading prevents glitching when applying an effect in the middle of a sound clip.

Crossfading is not available in real-time preview.

If Plug-In Extends Length

These options determine how Sound Forge handles the extra audio tail of plug-ins, such as reverb:

  • Select the Insert Tail radio button to insert the audio tail. All audio to the right of the tail will be moved over to accommodate the extra audio.

  • Select the Mix Tail radio button to mix the tail into the adjacent material. This is the most natural-sounding option.

  • Select the Ignore Tail radio button to ignore the tail. The effect will end abruptly at the end of the selection.
