Target Curves

DanDan · Jul 2, 2024

The old Bruel and Kjaer Curve was derived from pretty decent systems in domestic rooms and Hi Fi Shows. I spent two years in my highly treated Control Room searching for a curve that would be enjoyable to work with, and that would encourage mixes to translate instantly to three domestic playback systems in regular domestic rooms here. At the end I came right back to B&K. I mean right back. +/-3 at 100/10K does not make nicely sloped and rounded curves. It takes quite a few way points to get those slope right.

The smoothed response in Audiolense is different from the one the B&K is based on. So you will get a slightly different voicing than the B&K engineers heard.

Attached is a PDF with the Lyngdorf target curves.

I don't think these voicings are the "be all" and "end all" of best target curves, but they are a good start.

For example, the target curve that Moedra presented seems like a more sophisticated version of the Lyngdorf "Soft" voicing.

Trying a variety of target curves with Audiolense, we can train our ears/brain to have a better understanding of how frequency balance influences sound. Then we are in a good position to come up with our own preferred target curves.

Thanks Bernt. Thanks Billy. Yup, tweak to taste including the room and positions in it. Worth noting testing was at least a decade ago and I am approaching my 7th. I am beginning to ease off on the HF roll off......;-)

I hear colorations in all the Lyngdorf curves. I worked through a bunch of similay templates back in the Tact days,

Your mileage may vary, but I strongly recommend to opt for more subtle transitions between e.g the midrange region and a raised bass than what we see in the Lyngdorf curves.
