Hello.
I am using Panasonic WZ-DM35, a digital multi processer, as a parametric equalizer.
I planned to use REW, but I found a difference in the definition of the Q factor.
Then, I found the article: "Translating Q to Q – earfluff and eye-candy"
(I don't have permission to post links.)
The situation is the same, so I made a "translator" with Excel using the equation in the article.
I confirmed it's correct using a loopback connection.
While this solution is functional, it is undeniably tedious.
Here is some information I got while I was making the translator:
It allowing10 + 4 filters. Additional 4 filters support HS 6dB and LS 6dB in addition to PK filter.
Frequency
- Minimum: 40 Hz
- Maximum: 18,000 Hz
- Resolution: 1/24 oct (see attached file)
Gain
- Minimum; -15 dB
- Maximum: +15 dB
- Resolution: 0.5 dB
Q
- Values are 0.3, 0.35, 0.41, 0.47, 0.55, 0.64, 0.75, 0.87, 1, 1.2, 1.4, 1.6, 1.9, 2.2, 2.5, 3, 3.5, 4, 4.5, 5, 6, 7, 8,4, 10, 12, 14, 16, 19, 22, 25, 30
- (may be) bandwidth = center frequency/(Q/sqrt(10^(abs(gain/20))))
Your assistance in this matter would be greatly appreciated.
Thank you.
