Use the Wave tab in the Preferences dialog to specify which hardware devices Sound Forge should use for playing back and recording audio. To display this tab, choose Preferences from the Options menu and click the Wave tab.

What do you want to do?

Choose a playback device

From the Playback drop-down list, choose the device that you want to use for playing sound data.

Selecting a device such as the Wave Mapper or Microsoft Sound Mapper allows Windows to select an appropriate device to use for the current sound data.

Interpolate play position

Select the Interpolate play position for inaccurate devices check box if you want Sound Forge to interpolate the position of the cursor during playback. If this option is not checked, Sound Forge relies on the sound card device driver to provide the correct position of the pointer during playback.

Many sound card drivers do not report their position accurately. When you play sounds back, the position of the cursor may seem to lag or precede the sound you are hearing. If your sound card driver does not have accurate position reporting, your Drop Marker and Mark In/Out positions will also be incorrect when placing markers during playback.

Adjust play position bias

Drag the Play position bias slider handle to specify an offset value that Sound Forge will add to the position values returned by the sound card wave driver during playback.

Many sound card drivers do not report their position accurately. When you play sounds back, the position of the cursor may seem to lag or precede the sound you are hearing. If your sound card driver does not have accurate position reporting, your Drop Marker and Mark In/Out positions will also be incorrect when placing markers during playback.

When adjusting bias, start with smaller values and work toward larger values in increments of 4 (a value of 1 is equal to 512 bytes) until the play position pointer is accurate. Recommended settings are 4, 8, 16, and 32. These settings correspond to the typical bias values for these drivers of -2048, -4096, -8192 and -16384 (negative multiples of 2048) bytes.

Choose a recording device

From the Record drop-down list, choose the device that you want to use for recording sound data.

Selecting a device such as the Wave Mapper or Microsoft Sound Mapper allows Windows to select an appropriate device to use for the current sound data.

Interpolate recording position

Select the Interpolate record position for inaccurate devices check box if you want Sound Forge to interpolate the position of the cursor during recording. If this option is not checked, Sound Forge relies on the sound card device driver to provide the correct position of the pointer during recording.

Adjust recording position bias

Drag the Record position bias slider handle to specify an offset value that Sound Forge will add to the position values returned by the sound card wave driver during recording.

Many sound card drivers do not report their position accurately. When you play sounds back, the position of the cursor may seem to lag or precede the sound you are hearing.

Adjust the playback/recording buffer size

Drag the Total buffer size slider handle to select the amount of RAM you would like to use for buffering sounds during playback and recording. Using a large value can optimize performance at high sample rates, but may also cause a slight delay before playback begins.

Adjust .wav data preloading

Drag the Preload size slider handle to select the total amount of wave data that will be queued to the sound driver before playback starts.
