asymmetric apodizing filter


I have the esoteric K01 and it offers the standard filters and the newer filter designed to reduce preringing. They surely sound different. I would like to learn more.

Do the asymmetric or apodizing filters come with sonic tradeoffs or theoretical tradeoffs? Do they compromise phase linearities?

Thanks

Hi Glai - I recently uploaded an apodizing filter into my Meridian dac/preamp. To my ears, it is a remarkable improvement.

FWIW, I did NOT upload Meridian's proprietary apodizing filter, although I had the option to do so. Instead, I uploaded an apodizing filter created by an independent programmer.

My decision to install a non-official filter was based on multiple reports from Meridian owners who were less than overwhelmed by Meridian's proprietary filter. They felt that Meridian's filter removed some of the "air" in the recording. I'm just reporting something second hand, so keep that in mind.

I mention this because it highlights the fact that there appears to be quite a bit of variation among apodizing filters. I think it would be interesting if a manufacturer offered multiple apodizing filters in a single product. Maybe that will happen at some point.
