Three-band EQ frequency data

Post by krisz »

Hi!
Can someone help me with the three-band EQ control Mixcraft what frequencies?
I know it's high, medium, low.
But exactly what are the frequencies?
I tried to measure the spectrum analizerrel.
My measurements:
High: ~ 10 - 12 kHz
Mid: ~ 2 - 2.5 kHz
Low:~ 70 - 100 Hz

Don't know the exact split for Acoustica EQ but most most 3 band EQ's are set up to influence the in the following ranges:

Low Band - approximately 20 Hz to 250 Hz
Mid Band - approximately 250 Hz to 4000 Hz
High Band - approximately 4000 Hz to 20,000 Hz

+1. Not for sure either, but these are most common. The 31 band eq is nice as well!

Thanks for the answers, but the specific Mixcraft EQ care.
I do not know what frequencies to use.

Hi,

Here are those stats:

1) "Low" - Low shelving EQ at 125 Hz
2) "Mid" - Standard peaking EQ at 2500 Hz
3) "High" - High shelving EQ at 8000 Hz

Greg, are these the starting points for the shelving and the peak points of the curve?

Thank you Greg!

These three settings can also bring out a nice sound, but should be treated with caution.
I know the primary sound but now I know what to modify, and how. :idea:

I think this graphic might be rough approximation of the range. It may be exaggerated somewhat.

Typically the specification, such as 125 Hz low roll off point for example, is not where the reduction (or gain) STARTS, but where it crosses a certain point. (I can't recall exactly what the common spec is, 6dB or so. I'll see if I can find my reference, or maybe someone will chime in with the specifics.)

Hi ,
When considering the signal flow through the channel strip is seem the first thing the audio hits is the 3 "band" EQ, then the effects/inserts, then the send and then the Pan/Fader. At least as far as I can tell it always hits the EQ first.

Since the EQ is software and essentially the first "Plug in" do you have any idea what the optimal signal level should be entering the channel strip from the audio source file?

I have read elsewhere that most plugins are happiest with input signals somewhere between -18 to -10dbFS.

I have used the Blue cat trim insert to quiet down hot input tracks but those are still hitting the eq first.

Any thoughts?

HI,

That would depend on the individual plugins. Some plugins, like distortion effects, would be more sensitive to the input level. A lot of effects have an input volume control so you can adjust there.

From Mixcraft's perspective, your audio won't distort as long as you deal with any clipping using the master fader or master effects.
