Eq confused

  • Thread starter Thread starter maxman65
  • Start date Start date
So to interpret what I've done there via a hideous amount of trial and error .in effect has been to hear bad sound in that region and target it twice via the high and low shelf eq without actually understanding the principle of eq in this machine
 
No you've lost me again. if the high starts at 1.7 it cuts by the amount chosen and tapers above therefore below 1.7 is unaffected unless you match it in the low band
 
If the high band cuts above and the low band cuts below there has to be an unaffected gap unless the two values coincide
 
A high shelf will boost (or cut) everything above the corner frequency (the one you choose) by the amount you set.

A low shelf will boost (or cut) everything below the corner frequency by the amount you set.
 
Ok hold on so your saying the Db value is EQUAL in cutting amount across the range . Ie high shelf 1.7khz cut at 10db is also 10db up to the range of say 2khz. Note there's only one dB value you can select in this machine for either band I which case its a square cut not a triangle ?
 
Maxman, slow down. Go back to the start and read over the posts.
I've described it several times, and posted images showing what I mean.
 
Maybe it doesn't matter .everything round there in strings sounds like ear wasp to me so the more cut the better
 
I could find nothing from Tascam referencing EQ filter type, but this source has it described as 2-Band Shelving :

Tascam DP-008EX - 8 Track PocketStudio with Reverb, EQ, PP, 2GB Card

The Tascam DP-008EX is a 8-track digital pocketstudio with built in reverb, EQ and phantom power. It records to SD card and has a 2GB card included.

Hi-F would be high shelf frequency - the point above which everything is turned up or down.
Hi-G would be high shelf gain - how much it's turned up or down.

Lo-F would be low shelf frequency - the point below which everything is turned up or down.
Lo-G would be low shelf gain - how much it's turned up or down.

There are no means of adjusting the bandwidth to narrow or expand the bell curve, so no Band EQ setting and no means of adjusting the bell or slope to target specific frequencies.

I'm not in daw for this so there's no graphic representation as such. Can you interepret what the machine might be doing here

Nothing in your Screenshot indicates these are Low or High Shelf cuts - - they both look like Shelf EQ cuts or Parametric EQ - so you cut 1.6kHz and 1.7kHz by -10.5 db - if Parametric you will also have a Q (width) and Gain along with the Frequency controls - if a Shelf EQ you will Pull Down the Frequencies and some of the adjoining frequencies - you can change either Frequency with the parameters of the EQ - if a Low Mid Shelf EQ then you could vary the center frequency from about 80hz to 1.8 Khz or so - depending on where you wanted it centered.

Tascam literature says all the eq options on that unit are shelves.

Ok so shelf EQ is probable. I've emailed tascam directly to see if they know what their machine is doing more specifically around the targeted EQ value . However these were launched in 2013 so maybe they don't know
 
I imagine Tascam know what a shelf eq is.

Whether they explain it as clearly as us, with pictures, or not is another thing.
Good luck.
 
They likely will though they may not have any data on the specifics of the extent of range of frequency cut beyond a target point or by how much
 
Ultimately by modern recording standards it's a pretty basic machine . As such my instinct is that tascam won't really know
 
I'm not sure what you don't understand.

A shelf is just that. A shelf. If you set the frequency of a high shelf at 1k and cut by 10db, everything 1k and above will be cut by 10db.

If you set the frequency of a low shelf at 1k and cut by 10db, everything below 1k will be cut by 10db.

That is all there is to it.
 
Excellent . Nice . So Basically tascam have likely then programmed predesignated slopes in both shelves . A kind of simple plug and play solution set the cuts and thats it . They've been making standalone multitracks over 40 years so they probably hit it about right . Many thanks . Pretty much got the plot
