The Pan (preserve stereo separation) processing mode allows you to perform right- and left-channel panning effects without mixing the channels together. This is used to simulate left/right positioning of stereo recordings.

  1. From the Process menu, choose Pan/Expand.

  2. Choose Pan (preserve stereo separation) from the Process mode drop-down list.

  3. Adjust the envelope to achieve the desired sound:

  • Drag the small envelope points up or down to pan the audio left or right at that envelope point.

    For example, panning a stereo file hard right will play only the right channel through the right speaker.

  • To create a new envelope point, double-click the envelope.

  • To delete an envelope point, right-click it and choose Delete from the shortcut menu.

  • To change the fade curve between two points, right-click an envelope segment and choose a command from the shortcut menu:

  • To move all envelope points, press Ctrl+A and drag when the envelope has focus (the cursor will be displayed as a Sound Forge Pro handpointer Pan/Expand).

  1. Drag the Output gain fader if you want to apply a gain after processing.

  2. Click the OK button.

The Pan (mix channels before panning) processing mode allows you to perform right- and left-channel panning effects by first mixing the two channels and then changing the volume between channels.

  1. From the Process menu, choose Pan/Expand.

  2. Choose Pan (mix channels before panning) from the Process mode drop-down list.

  3. Adjust the envelope to achieve the desired sound:

  • Drag the small envelope points up or down to pan the audio left or right at that envelope point.

    For example, panning a stereo file hard right will play the mixed right and left channels through the right speaker.

  • To create a new envelope point, double-click the envelope.

  • To delete an envelope point, right-click it and choose Delete from the shortcut menu.

Choose a command from the Show wave drop-down list if you want to display the waveform in the envelope graph.

If you’re working with a stereo file, you can choose to view individual channels or the mixed waveform.

Sound Forge Pro note Pan/ExpandThe waveform is unavailable when the selection is greater than 300,000 samples.

The Stereo expand processing mode allows you to contract or expand the stereo image of a stereo recording, from dead center (mono), to completely panned wide (no center channel). For realistic effects, you should not venture too far from Normal.

Sound Forge Pro note Pan/ExpandNotes:

  • This effect works best with true stereo recordings and will not work with mono material.

  • Panning a stereo recording toward the center can emphasize vocals; widening the image can de-emphasize vocals.

  1. From the Process menu, choose Pan/Expand.

  2. Choose Stereo expand from the drop-down list.

  3. Adjust the envelope to achieve the desired sound:

  • Drag the small envelope points up or down to expand or contract the stereo image.

  • To create a new envelope point, double-click the envelope.

  • To delete an envelope point, right-click it and choose Delete from the shortcut menu.

  1. From the Process menu, choose Pan/Expand.

  2. Choose Mix Mid-Side (MS) recording to left and right channels from the Process mode drop-down list.
