EQ or equalization allows you to lower or raise the volume of specific frequency ranges. This effect is comparable to the graphic equalizer control commonly found on stereo amplifiers. The Acoustica EQ effect can subtly color the sound or give you a dramatic change, from a low-fidelity sound of AM Radio to subtle mid-range boosts on a vocal recording.
EQ bands
You can change the amplification for 10 frequency bands by 18 dB. The bands represent 32 Hz, 63 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz & 16 kHz.
Output Gain
This allows you to raise or lower the equalized sound. In some cases, a particular equalization might cause distortion and, thereby, you’d want to reduce the output gain.
Reset
This resets all frequency bands to their center position and the output gain to 0. This is the default position and is the same as muting or disabling the EQ.
Tips
q Choose the "Telephonic" preset to make your mix sound like its going through a telephone.
q Choose the "Lo-Fi" or "1960s" preset to make your mix sound like its on a cheap TV.
q Try to avoid over equalizing. Not all speakers are created equal. For example, if you boost the bass real high, many systems may not be able to play it properly. Aim for the common denominator speakers. Of course, if you are making a mix for a dance club, give it some more bass and then give it some more. J
* EQ note: If you are playing back sounds with lower sample rates such as 22,050 Hz or 11,025 Hz, some of the higher bands will not have any audible effect as it is impossible to contain frequencies above ½ the sampling rate. (An 11,025 Hz sound cannot contain frequencies above 5,012 Hz (Nyquist’s theorem) )
