New build of rev. 2.0.46.1 available.
Qms and Vas calculated without frequency-dependent compliance with Dual added mass & LOG model to reduce difference to traditional T/S values. This is just workaround to avoid separate R0 and C0 fields in driver database.

Hi,
As usual, thanks you for these piece of software !!!


Since on month now I've got this kind of error during new driver import in the enclosure tool (Datas from loudseapkerdatabase.com)

^Oops, that was fixed 3 days ago to Paste command in Add/Edit driver window, and rev. 2.0.46.2 also to Update database... with xml file. Bug since 2.0.38.0 (2020-02-28) due to squared and '/' characters which are illegal in xml element name. Thanks for info!

Rev. 2.0.46.3 (2020-03-24)

Main
* SPL and delay of acoustical simulation normalized by distance from speaker's origin to virtual microphone no matter microphone offset X,Y mm in Drivers tab. Earlier normalization was by Listening distance set in Options window causing excess delay and reduced readability of phase responses if microphone was moved.

Enclosure
* Added paste from speakerbench.com in json format to Add driver window.

^Not yet, but 2x1 and 2x2 should be doable in addition to existing 1x1 and 3x2. Zoomed Power & DI is quite adequate alone for final fine adjustments.

Rev. 2.0.46.4 (2020-03-29)

* Impedance response files with less than 48 ppo read with cubic spline interpolation to reduce error especially with T/S parameter extraction.

Calculate T/S parameters
* Solving weights and tolerances adjusted to improve fitting of extended impedance model with Le, Leb, Ke and Rss.
* Checking of known Mms or BL enables Calculate button without loading second impedance response.

This is second build so check that date in about box is 2020-03-29.

when working with a crossover, is it possible to lock the graphs so they do not automatically adjusts to the response curve levels?

^No, but jumping is possible to minimize by scaling driver responses so that total SPL is about 87, 92 or 97 dB etc. Hysteresis prevents jumping if maximum point stays within -0.2...-6.8 dB below Y maximum.
