Equalization, or simply EQ, in sound recording and reproduction is the process of adjusting the volume of different frequency bands within an audio signal. The circuit or equipment used to achieve this is called an equalizer. [1] [2] Most hi-fi equipment uses relatively simple filters to make bass and treble adjustments. Graphic and parametric ...
A monitor engineer and console at an outdoor event. Live sound mixing is the blending of multiple sound sources by an audio engineer using a mixing console or software. Sounds that are mixed include those from instruments and voices which are picked up by microphones (for drum kit, lead vocals and acoustic instruments like piano or saxophone and pickups for instruments such as electric bass ...
A dynamic equalizer can be used to achieve the same effects as a de-esser, however, plugin manufacturers have tailored these tools to operate efficiently within the mid-high to high frequencies. A de-essing plugin will compress the desired signal according to the amplitude of the selected frequency as it passes over a preset threshold.
For example, in Europe, for many years recordings required playback with a bass turnover setting of 250 to 300 Hz and a treble rolloff at 10,000 Hz ranging from 0 to −5 dB, or more. In the United States, practices varied and a tendency arose to use higher bass turnover frequencies, such as 500 Hz, as well as a greater treble rolloff such as ...
For example, mix 1 vocals, mix 2 guitars, mix 3 keyboards, and mix 4 drums and bass. The performers can then adjust these four groups to their own preferences. If the balance between several vocals or the balance between bass and drums needed to be changed, the sound engineer would have to change it at the main mixing console.
Threshold timing behavior is subject to attack and release settings (see below). When the signal level goes above threshold, compressor operation is delayed by the attack setting. For an amount of time determined by the release after the input signal has fallen below the threshold, the compressor continues to apply dynamic range compression.
The most common use of pitch correctors is to fix wrong intonation (tuning) of notes sung by vocalists in popular music sound recordings. The use of pitch correction speeds up the recording process, because singers do not need to keep singing a song or vocal line and re-recording it until the pitches are correct.
Dynamic equalization involves variation of the equalizer characteristics in the time domain as a function of the input. Due to the varying nature, noise is reduced compared to static equalizers. Harmonic synthesis involves the creation of higher order harmonics from the fundamental frequency signals present in the recording. As noise is usually ...
