The Equalizer in Music Speed Changer - EQ Explained

Support

Music Speed Changer has an 8-band graphic equalizer for amplifying and attenuating a track's audio. The center of the bands, from low to high, are 60, 150, 400, 1K, 2K, 4K, 8K, 16K Hertz. The bands' vertical sliders allow you to control the gain of each of these bands separately. This is useful for boosting the bass, filtering out high frequencies, or tuning in on one band. The equalizer can be added to custom editor layout or accessed directly as a component preset.

Getting Started with the Equalizer

The quickest way to use the equalizer is from the component presets, under the player main menu, Editor components:

Open the Editor


Open the Editor Layout Menu by tapping the slider/gear icon at the top of the editor. Here you can select one of the editor presets or you can customize the editor


Select Equalizer

Adding the Equalizer to your Editor Components

Alternatively to using the equalizer component preset, you can add it to your controls by using a custom setup:

Open the Editor


Open the Editor Layout Menu by tapping the slider/gear icon at the top of the editor. Here you can select one of the editor presets or you can customize the editor


Select Configure custom


Turn on Custom components


Check the Equalizer checkbox


Turn on the Equalizer

Using the Equalizer

The vertical sliders control each band's gain. From left to right, the frequencies are from low (bass) to high (treble).

Bass Boosting with the Equalizer

To bring out the bass in a track, you want to amplify the low frequencies. To turn up the low frequencies move up the left sliders.

Filtering out Low and High Frequencies

To get a low/high filter effect, you can attenuate (turn down) the low and high frequencies by moving down the outer most sliders. For maximum effect, amplify (boost) the mid range signal by moving up the middle sliders.

Dealing with Distortion aka Clipping

Clipping occurs when an audio signal is boosted above it's maximum level. This can be a common occurrence when boosting specific frequencies with the equalizer. To counteract clipping, lower the preamp gain to provide headroom for boosting frequencies with the equalizer. The compressor and/or limiter may also be helpful with the added benefit of less attenuation of the unboosted frequencies.

448 Hz

Keep in mind that when you do add 20 Hz, it's gonna add a lot more sub with the 60 Hz. 150 Hz is bass too as well, but some songs may not be felt as much with the 60 Hz together. Will you please add 20 Hz to the equalizer?

448 Hz

I just now realized that if I turn up 150 Hz itself at +15 dB, the bass is barely felt, including 60 Hz at -15 dB. 60 Hz is the pure body of bass, as well as 20 Hz. Just 60 Hz makes me feel the bass a lot more now. Even though 150 Hz is the body part if the bass, it makes it harder to feel the bass completely.

448 Hz

Will you please update the equalizer by adding 20 Hz? It's the lowest of all bass notes that catch the super low deep bass notes in music.
