I thought they are the same thing....

make sure to unload the FIR file and send to dsp, before loading a new file.
That might be why you're getting strange numbers...files adding together??

And I would definitely use the 48K plugin...

Have changed to the 48k plug in. It still says there are too many coefficients. Seems the coefficients need to match the number of taps.
Only way to make this work is to set a real small number of taps in Rephase.

I'm doing something wrong for sure...

When in FIR Filter (in any channel) 4x8 or 4x8/96:

- choose File mode

- BEFORE you Browse/Load/Send to DSP your intended filter, you must enter manually the number of taps in the "Taps used" field , in the lower right corner above the "Taps Available".

- You need to enter the number which is equal to or higher than the number of taps your filter uses. Program will inform you that if you have "spare" taps unused, it will fill them as zero....

- After this, you can download and "Send to DSP", AND then unclick "Bypass"

- Lastly: tap=coefficient AFAIK

Thanks Dealing
Yea did that.... redid the rePhase with 1024 taps, set taps used to 1024 and selected the filter file. Same message, too many coefficients. Try again.

Are the rePhase files 32 bits IEEE - 754 mono (.bin) ?
That's the only one I know to work in plugins....

The program "sees" your 1024-taps designed as 6067.75 taps! Did you check the correct file format needed for MiniDSP?

EDIT: Mark100 already posted the correct file format////

I agree with WESAYSO. For low frequency, low tap FIR is not recommended. 262144 is my current impulse length. That's the max number I can do with my computer, but I wish I can make it higher in the future. Digital technology is still very immature.
