ADOBE PREMIERE PRO CS3 357 User Guide Male and Female Specifies the gender of the narrator or vocalist. This option helps the effect to adapt to the difference in tone between genders. DeHummer effect The DeHummer removes unwanted 50 Hz / 60 Hz hum from the audio. This effect is available for 5.1, stereo, or mono clip. Reduction Specifies the amount of reduction to apply to the hum. High values may also cut necessary audio information in the low end. Frequency Specifies the center frequency of the hum. Usually this will be 50 Hz in Europe and Japan, and 60 in the US and Canada. Often the frequency of the hum is not static, but will vary by +/- 5 Hz. Click the 50 Hz or 60 Hz buttons to set the respective frequency. Filter Specifies the number of filters to use to remove the hum. Hum is comprised not only of the fundamental frequencies of 50 or 60 Hz, but also contain harmonics with frequencies that are multiples of the fundamental (100/110 Hz, 150/160 Hz, and such). Higher values cause greater CPU usage. Adjusting this value determines the number of harmonic frequencies to filter. For example, if you choose 60 Hz as the Frequency value, and choose 4# as the Filter value, the DeHummer filters the 60 Hz frequency along with three harmonic frequencies (120 Hz, 240 Hz, and 480 Hz), for a total of four frequencies filtered, hence the value of 4#. Higher values require more processing power. Delay effect The Delay effect adds an echo of the audio clip's sound that plays after a specified amount of time. This effect is available for 5.1, stereo, or mono clip. Delay Specifies the amount of time before the echo plays. The maximum is 2 seconds. Feedback Specifies a percentage of the delayed signal to be added back into the delay to create multiple decaying echoes. Mix Controls the amount of echo. DeNoiser effect The DeNoiser effect automatically detects tape noise and removes it. Use this effect to remove noise from analog recordings, such as magnetic tape recordings. This effect is available for 5.1, stereo, or mono clip. Noise Floor Specifies the level (in decibels) of the noise floor as the clip plays. Freeze Stops the noise floor estimation at the current value. Use this control to locate noise that drops in and out of a clip. Reduction Specifies the amount of noise to remove within a range of -20 to 0 dB. Offset Sets an offset value between the automatically detected noise floor and the value defined by the user. This is limited to a range between -10 and +10 dB. Offset allows additional control when the automatic denoising is not sufficient. April 1, 2008
