SoundSoap Pro Hum And Rumble

The type of noise known as "hum" is typically composed of a fundamental frequency (such as 60Hz) and its harmonics, and is often associated with audio equipment being used on faulty electrical circuts, or equipment that is not properly grounded. Rumble is a similar type of noise to Hum — but typically occurs at lower frequencies, usually at around 40 Hz or below.

SoundSoap's Hum & Rumble tool effectively eliminates buzzing and hum from RFI, EMI and other sources. It operates from 20 - 500 Hz w/Q (Hum and Rumble), up to 9 harmonics (Hum), and reduces low-frequency and subsonic rumble.

Use SoundSoap Pro's Hum Meter along with your ears as a visual feedback tool to help locate the fundamental frequency causing a particular hum.

The Hum Frequency Slider allows you to reduce a specific frequency. If the frequency causing a hum is unkown, the Hum Frequency Slider may be swept as the noisy media file is played, and the Hum Meter will register the activity as you approach the offending fundamental frequency.

The Q Slider determines the bandwidth of the notch filter being applied to a particular frequency. The Depth Slider will control the amount of audio being cut put by the notch filter responsible for eliminating hum, and is directly related to both the Q Slider and the Hum Frequency Slider.

SoundSoap Pro's Harmonics Slider designates how many harmonics of the fundamental frequency should be removed in either direction from the fundamental frequency. The Harmonics Tilt Knob allows you to fine-tune the relationship between how much of the fundamental frequency is cut, and how much of the signal is cut at each harmonic.

The Rumble Reduction Slider focuses on very low frequency noise, commonly known as "rumble".
