A distortion meter detects and eliminates harmonic distortion in sound by analyzing and modifying the full range of sound waves. It is commonly used in music and sound production industries to remove hiss, hum, and background noise. Distortion meters are also used to eliminate distortion waves within circuits. They can be analog or digital and set specific parameters for pure, clean frequency.
A distortion meter is used to detect frequencies causing harmonic distortion. The meter allows the user to alter or eliminate any sources of distortion within the sound. This means that the user can view the frequency measurements made from the source sound and add or completely remove every single wave within the entire frequency range of the sound.
Any sound is the direct result of a vibration of matter. Whether it’s a person sighing or an electric amplifier screaming when a guitar string is plucked, sound contains frequencies that are used to create the volume and pitch of that sound. Within these natural frequencies, there may be a single frequency causing an element of harmonic distortion, which in some cases is so small that it is not easily detectable by the human ear alone, and in some cases can be immediately identifiable. The distortion meter can remove or change any of these frequencies.
The most common uses of distortion meters are in the music and sound production industries. Whenever sound is recorded in a controlled environment, and especially when sound is recorded in a natural environment and mastered or engineered in a controlled environment, the full range of sound waves must be analyzed and modified to be easier on the eardrum. . This means that any nuances of hiss, hum, reverberation or background noise that may be causing frequencies within the base sound must be considered. The distortion meter puts a visual on each different wave within the sound, allowing the user to alter or eliminate the specific wave responsible for the distortion.
Distortion is also present whenever there is an electric current traveling through a circuit of any kind. This current causes vibration within the circuit and the vibration causes distortion. Distortion within a circuit cannot be heard, so a distortion meter is used to eliminate all sources of distortion waves within the circuit when current through the circuit must be accurately maintained.
The only way to get pure, clean frequency within any sound or circuit is through the use of a distortion meter. The distortion meter can be used to set specific parameters at which the frequency or circuit could travel without creating distortion, eliminating any sound waves or frequencies outside the parameters set by the user. Older distortion meters were analog machines that used input/output ports to complete the circuitry needed to measure sound. Newer models work digitally and may even be programs that can be installed on personal computers to measure sound waves entered into the program by the user.
