ADOBE PREMIERE PRO CS3 362 User Guide PitchShifter effect The PitchShifter effect adjusts the pitch of the incoming signal. Use this effect to deepen high voices or vice versa. You can adjust each property using graphical controls in the Custom Setup view, or by changing values in the Individual Parameters view. This effect is available for 5.1, stereo, or mono clips. Pitch Specifies the change in pitch in semitone steps. The adjustable range is between -12 and +12 semitones. Fine Tune Determines the fine tuning between the semitone grid of the Pitch parameter. Formant Preserve Prevents formants in the audio clip from being affected. For example, use this control when increasing the pitch of a high voice to prevent it from sounding cartoon-like. Reverb effect The Reverb effect adds ambience and warmth to an audio clip by simulating the sound of the audio playing in a room. Use the graphical controls in the Custom Setup view, or adjust values in the Individual Parameters view. This effect is available for 5.1, stereo, or mono clips. Pre Delay Specifies the time between the signal and the reverberation. This setting correlates to the distance a sound travels to the reflecting walls and back to the listener in a live setting. Absorption Specifies the percentage in which the sound is absorbed. Size Specifies the size of the room as a percentage. Density Specifies the density of the reverb "tail." The Size value determines the range in which you can set Density. Lo Damp Specifies the amount of dampening for low frequencies (in decibels). Dampening lower frequencies prevents the reverb from rumbling or sounding muddy. Hi Damp Specifies the amount of dampening of high frequencies (in decibels). Low settings make the reverb sound softer. Mix Controls the amount of reverb. Spectral Noise Reduction effect The Spectral Noise Reduction algorithm uses three notch filter banks to remove tonal disturbances from audio signals. It can help eliminate noises from original footage, such as buzz and whistling tones. Freq (1-3) Determines the center frequency of each of the notch filters. Red (1-3) Sets the input gain level at which the color red appears in the meter for a given track. On (1-3) Activates the corresponding filter bank. MaxLevel Determines the gain reduction of each notch filter, thus controlling the amount of noise removed from the signal. CursorMode Activates the adjustment of the filter frequency by the cursor. Swap Channels effect The Swap Channels effect switches the placement of the left and right channel information. Apply to stereo clips only. April 1, 2008
