Mp3 Equalizer – Equalize your mp3s
PRO-Mp3Doctor Elsoftware unlike other mp3 normalizers, has an equalizer.
We briefly see that it is an equalizer and what is its function and capabilities.
Graphic equalizers are the most common and most used in recording. The Mp3Doctor PRO has a graphic equalizer.
The most common is the octave equalizer, which will have 10 control points, as the audible bandwidth octabas 10 runs that are 30 Hz, 60 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 KHz, 4 KHz, 8 KHz, 16 KHz.
It is at those frequencies where we let stand the equalizer, graphic equalizers generally allow us to increase or decrease the intensity of the audio signal between 6 dB and 15 dB over the same frequency.
The equalizers can be employed as filtersthat is to eliminate or reduce as far as possible annoying frequency, noise, interference and so on. That mix with the sound.
For instance, sometimes the recording is a buzz due to poor power supply, and what we can do is to reduce that hum diminishing the 50 Hz 60 Hz, or for example the familiar whistle could reduce attenuating higher frequencies.
Generally this type of problem occur in a particular frequency range, and that is why so a parametric equalizer is ideal for such purposes.
Another quite common event is that a individually instrument sound good and when we mix with others it interferes with the clarity of others, this is because it has a peak at a frequency which should mitigate these frequencies. This problem is known as masking.
The equalizers can also be employed to change the character or the sound of an instrument.
To do so will only have to change the harmonics or the fundamental frequency. We must take into mind a very important thing, is that if we alter all the instruments separately then mix when it is not certain that we get a good result in the mixture.
Any sound source produces sound into a given area of the audible frequency spectrum, which is where the EQs operate changing the frequency response.
The graphic equalizer is a sound processor that enables us to partition and get portions of the original audio signal and alter the volume level independently.
Graphic EQ has a certain amount of slide faders called bands, depending on make and model we can find 10 bands in the most common.
Each band is in charge of increase or decrease the signal (volume) of a given frequency, these range from 20 Hz (this means that the air vibrates at a rate of 20 times per second), up to 20kHz (air oscillates a rate of 20,000 times per second) varies faster the air, the sound you hear will be more sharp.
