Re: Filter Generation detects a 1-way filter

Hi Uli,

maybe it would be possible to implement that the Logsweep Recorder uses the XOs from the Project Folder instead of loading a Multiway Wav that is not used in the creation of the Filters?

Best Regards,
Peter

Re: Pulse Peak of linearized XOs not at sample position 32768

Hi Uli, thanks a lot, so my linearized XOs are ok. So now follows the time alignment. I rotated the individual linearized XOs for the delay measurement, made a 4-Way XO and took a Logsweep-measurement. Now comes the comparison of the Logsweep with the linearized XOs. For the Left Woover, the (for th...

Pulse Peak of linearized XOs not at sample position 32768

Hi, I am trying to linearize and time align active 3-way speakers plus subwoover following the steps in Mitch Barnetts book. During the time aligning process I noticed that the pulse peaks of the linearized XO2L48.dbl, XO2R48.dbl, XO1L48.dbl and XO1R48.dbl (woovers and the subwoover) are not at samp...

FIR Filter for miniDSP 2x4 HD 1 plugin

Hello,

How can I generate FIR filters for the miniDSP 2x4 HD 1 plugin?
The datasheet says the filters can have 4096 tabs. I know that is not much, but worth a try :)

Thanks
Peter

Re: Virtual Bass Array

Hi Jörn,

thanks, now I'll take a long listening session to check if I didn't make any mistakes.

Re: Virtual Bass Array

Hello Uli, I could follow the steps up to the creation of the echo compensation filter for my room. I also could convolve the filter with the measurement of my room at my listening position, to see the result. Now I'm not shure how to proceed. My setup: a subwoover and active 3-way speakers. With Ac...

Re: RIAA Filter and Phono Cartridge Load

Hi Uli,

thanks, this worked.

Anyway, now with more highs I could hear a high sine tone like from an old tube TV. Maybe this is another effect of the impedance mismatch.

So I decided to use my analogue Phono Preamplifier and connect it between turntable and Fireface.

RIAA Filter and Phono Cartridge Load

Hi, I'm connecting a turntable directly through a Fireface UC to a PC. On the PC I'm using brutefir to convolve the signal from the turntable with the Acourate RIAA Filter. It sounds like the sound is missing some height. I think that this is because the Phono Cartridge expects a load of 47 kOhms, a...
