Compressor and Limiter
Introduction
Compressors and limiters are two types of audio processing devices that are used to reduce the dynamic range of an audio signal. Dynamic range is the difference between the loudest and quietest parts of an audio signal. Compressors and limiters can be used to make an audio signal more consistent and even, or to create specific effects.
Compressor
A compressor works by reducing the level of the signal when it exceeds a certain threshold. The amount of reduction is determined by the ratio setting. A ratio of 2:1 means that for every 2dB that the signal exceeds the threshold, the compressor will reduce the level by 1dB.
Compressors have a number of controls that can be used to adjust their behavior. These controls include:
Threshold: The threshold is the level at which the compressor will start to reduce the signal.
Ratio: The ratio determines the amount of reduction that will be applied to the signal when it exceeds the threshold.
Attack: The attack determines how quickly the compressor will start to reduce the signal when it exceeds the threshold.
Release: The release determines how quickly the compressor will stop reducing the signal when it falls below the threshold.
Compressors can be used to achieve a variety of effects, including:
Evening out the dynamic range: Compressors can be used to make an audio signal more consistent and even. This can be useful for making vocals or instruments more present in a mix.
Creating sustain: Compressors can be used to create sustain on instruments that naturally have a short decay, such as electric guitars or bass guitars.
Adding punch: Compressors can be used to add punch to an audio signal. This can be useful for making drums or percussion instruments stand out.
Limiter
A limiter is a type of compressor with a very high ratio. Limiters are typically used to prevent the signal from exceeding a certain level. This can be useful for preventing distortion, or for ensuring that an audio signal does not exceed a certain level, such as the maximum output level of an amplifier.
Limiters have a number of controls that are similar to those of compressors. These controls include:
Threshold: The threshold is the level at which the limiter will start to reduce the signal.
Ratio: The ratio determines the amount of reduction that will be applied to the signal when it exceeds the threshold.
Attack: The attack determines how quickly the limiter will start to reduce the signal when it exceeds the threshold.
Release: The release determines how quickly the limiter will stop reducing the signal when it falls below the threshold.
Limiters can be used to achieve a variety of effects, including:
Preventing distortion: Limiters can be used to prevent distortion by preventing the signal from exceeding a certain level.
Maintaining a consistent level: Limiters can be used to maintain a consistent level for an audio signal, even if the input level varies.
Adding punch: Limiters can be used to add punch to an audio signal by preventing the signal from dropping below a certain level.
Comparison
Compressors and limiters are both used to reduce the dynamic range of an audio signal, but they do so in different ways. Compressors have a variable ratio, which means that they can reduce the signal by a small or large amount, depending on how much the signal exceeds the threshold. Limiters have a very high ratio, which means that they reduce the signal by a large amount, regardless of how much the signal exceeds the threshold.
Compressors are typically used to achieve subtle effects, such as evening out the dynamic range or adding punch. Limiters are typically used to prevent distortion or maintain a consistent level.
Conclusion
Compressors and limiters are powerful tools that can be used to improve the sound of an audio signal. By understanding how they work, you can use them to achieve a variety of effects.
