WinISD pro 0.50 test versions

Version history

2004-09-16:

• 0.50a7 version released officially today, so no intermediate updates yet.

2004-04-13:

• Added parameter status tracking to the driver editor (calculated, entered, not available).
• Added parameter checking to the driver editor. Driver editor now refuses to save incorrect data entries.
• Added apparent amplifier power graph.
• Added "static gain filter" to the filter simulator, for normalizing purposes.
• Revised the help file a bit. Incomplete, though.

2003-19-10:

• Fixed divide by zero in maximum SPL and maximum power graphs when Sd was not entered.
• Fixed passive radiator cone excursion calculation.
• Fixed maximum power/maximum SPL calculation in passive radiator enclosure.

2003-09-10:

• Updated all models to support voice coil inductance.
• Some cosmetic fixes by Juha Hartikainen.

2003-05-13:

• Fixed Maximum SPL calculation with closed boxes.

2003-02-15:

• Added relative cursor readings.
• Added experimental support for voice coil inductance in closed boxes. In fact the whole model is entirely rewritten. If graphs look too weird, then change Le to 0 to disable the effect.
• Fixed "number of vents"-selection.

2003-01-29:

• Project form GUI code tweaked a bit.
• Added simulation of user specifiable (fp,Q) highpass and lowpass second order sections (SOS).

2003-01-26:

• Changed filter list to CheckListBox (Juha).
• Improved editing to some fields.

2003-01-19 (2):

• Fixed Y-axis scaling in excursion and velocity plots.
• Fixed scaling of multiple driver case. Affected most power dependent graphs.
• Some improvements with project window edits. End correction combobox still doesn't work as expected.

2003-01-19 (1):

• Saving of project filters added.
• Added bessel highpass filters.

2003-01-18:

• Fixed bug in Linkwitz transform, transfer function pole/zero calculation failed when Qp/Q0<0.5.
