Normalizing

Normalizing a file prior to decreasing its bit depth ensures that the entire dynamic range is used. In addition, normalization lowers the signal-to-noise ratio.

1.From the Process menu, choose Normalize. The Normalize dialog appears.

Note: The Normalize dialog pictured here is from the full version of Sound Forge. If you are using Screenblast Sound Forge, not all of the controls pictured here will be available to you.

2.Select the Peak level radio button.

3.Set the Normalize to fader to 0 dB (peak) and click OK.

Applying compression and normalization simultaneously

1.From the Process menu, choose Normalize. The Normalize dialog appears.

2.Select the Average RMS power radio button.

3.Specify Apply dynamic compression in the If clipping occurs drop-down list and click OK.

Converting mono/stereo channels

The channels setting indicates whether a file contains one (mono) or two (stereo) channels. Sound Forge can convert mono files to stereo or stereo files to mono.

Converting from mono to stereo

1.Open the Voiceover.pca file.

Note: This file is located in the same folder as the application.

2.Right-click the Channels status box and choose Stereo from the shortcut menu. The Mono To Stereo dialog appears.

3.Select the Left Channel radio button and click OK. Sound Forge places the mono data in the upper half of the data window (left channel) and silence in the right channel.

For more information, see Specifying the audio destination on page 88.

4.Play the file. “Wow, sound editing just gets easier and easier” plays in only the left channel.

Tip: If your sound card supports only mono data, stereo files can be played by specifying the Sound Mapper as the playback device. To do this, choose Preferences from the Options menu. Click the Wave tab and specify Microsoft Sound Mapper from the Playback drop-down list.
