Monitoring an input and output source

Click the Real Time Monitoring button () to turn real-time spectrum analysis on or off. Click the down arrow next to the button and choose a command from the menu to specify whether you want to monitor your sound card’s input or output:

•When you choose Monitor Input, Sound Forge will monitor the recording devices selected on the Record page of the Audio tab in the Preferences dialog. For more information, see Audio tab on page 322.

•When you choose Monitor Output, Sound Forge will monitor the playback devices selected on the Playback page of Audio tab in the Preferences dialog. For more information, see Audio tab on page 322.

Notes:

•When Monitor: Output is selected, the post-processing signal is monitored when you start playback from the Plug-In Chainer.

•Real-time spectrum analysis can require significant processing power. If the spectrum graph’s refresh rate seems sluggish, set the display mode to Line Graph, decrease the FFT size, or turn off snapshots.
