high frequency delay

[pasiasty]

Hello all,

I'd like to apply a delay only on higher part of the frequency spectrum to match it in time with a little bit slow bass region of my speakers. Is it possible with EQ APO, how do I achieve this? Thanks in advance.

After splitting the frequency spectrum into a low and high part you can perform a delay on the high part and then mixed the two parts together again. For example by low/high graphic EQ:

# create channels for high and low parts
Copy: HR=R
Copy: HL=L
Copy: LL=L
Copy: LR=R
Channel: HL HR
# use graphic EQ to cut low part
GraphicEQ: 1000 -30; 2000 0
# delay for slow bass region of your speakers
Delay: 50.0 ms
Channel: LL LR
# use graphic EQ to cut high part
GraphicEQ: 1000 0; 2000 -30
# mix it together again
Copy: L=HL+LL
Copy: R=HR+LR

You can change the frequency of both GraphicEQ to match it with the bass region of your speakers. And change the 50 milliseconds delay to the needed delay.

hello,

I am a bit confused regarding the above prompts, especially when I get to the Graphic EQ part.

Where exactly do I fill in the prompts of 1000 - 30; 2000 0?

And what does it mean exactly? For example is the 1000 - 30 the frequecy range...? Then what is the 2000 and 0?

Regards

Hmm... there's this documentation you know.

Synthax is: frequency1 gain1 ; frequency2 gain2; .... frequency n gain n
For instance 1000 10; 2000; 5 means 10 dB at 1000 Hz and 5 dB at 2000 Hz
