MULTI BAND VS SINGLE BAND COMPRESSOR PRO

Single-band limiters work on the full-bandwidth audio, meaning that a peak in any frequency band will cause the level of the entire audio signal to be reduced. There are two basic types of limiters: single-band and multi-band. These processes are being used more and more, especially in radio where everyone wants their stations to be the loudest on the dial, and we are seeing the same choices more and more in CD mastering where clients want their CD to be louder than anybody else's! Single-band & Multi-band

In addition, using a limiter allows us to increase the loudness of the audio whilst maintaining the same peak level, if we are prepared to permit more frequent occurrences of limiting and therefore gain reduction of the peaks. In digital systems, as opposed to analogue tape, this is important as there is no warning of distortion: the signal is OK until 0dBFS is reached, and then it clips in an ugly fashion. Because using a limiter allows us to control the maximum signal level, we don't need to leave any headroom in the system after the limiter in case the audio gets louder than we had expected. Limiters are often used to protect transmission chains, for instance in broadcast transmitters or CD mastering, to prevent peak distortion that would occur if the audio were allowed to pass unchecked. When the input is below the predetermined level, usually called the threshold, the audio dynamics are not changed at all any input signal that exceeds the threshold level is 'limited' to that level. Limiters are audio devices that prevent a signal from going above a defined level, irrespective of the input level. But which one? We put the leading contenders to the test.

The three-band Drawmer S3 is a hardware example.If you want to get maximum level out of your Pro Tools mixes, you need a mastering limiter. Multi-band compressors are most common in the form of plug-ins, e.g. As a result, a low frequency impulse leaves the overtone spectrum of other instruments unaffected. It separates the spectrum into several frequency bands, each of which can be compressed individually. This isn't always desirable and can be prevented by using a multi-band compressor. For example, if a loud bass drum impulse triggers the compression, the entire audio spectrum is affected, including the middle and high frequencies of other instruments. Single band compression can reach its limitations when it comes to processing a stereo sum during mixdown or mastering. In contrast, a linked compressor applies the same processing to both channels, preserving the stereo image. If, for example, a loud impulse occurs in the left channel only, the left channel would attenuate the signal, while the right channel would not be affected, resulting in a level offset between the two channels. Linking the two channels is important, because using two seperate mono compressors (even with identical settings) can affect the stereo panorama of the signals. In dual mono compressors with a link option, the controls for the right channel will be without function in link mode. The operational amplifier for the right channel automatically matches the settings of the left channel. The control signal is ideally derived from a mono sum of the two channels. It is essential that both channels can be linked. Single band compressor (stereo)ДЇor processing stereo signals such as the overhead microphones on a drum kit, a dual-channel (stereo) compressor is needed. This type of compressor is suitable for the treatment of single instruments or voices, which are typically tracked in mono. multi-band compression Single band compressor (mono)ДЄ single band compressor (mono) processes the entire frequency range of the incoming signal with a single operational amplifier.
