I began working on this program years ago, back in 2010. Now, having just finished version 3, it occurred to me that sharing it here might be a good idea - especially since I use it regularly myself. Essentially, it’s a simple yet effective tool: while it only simulates SPL amplitude versus frequency, it’s straightforward, intuitive, and gives me exactly what I need when working with loudspeakers.
Some of the features:
Some antivirus programs - including Windows Defender - may mistakenly flag it as suspicious. This is a false positive. To verify its safety, you can check its status using the VirusTotal API.
Some of the features:
- A large loudspeaker database is included, mostly up to date. To add a new driver for simulation, only six parameters are required: Qms, Qes, fs, Mms, Dd/Sd, Re. The remaining parameters are calculated automatically. A small "=" symbol in the lower-right corner allows you to rename records.
- The Up/Down arrow keys change the numeric value by +/-1. For fine-tuning, hold down the Shift or Ctrl key beforehand.
- Double-clicking on the form expands or contracts the window; double-clicking on the graphs quickly redraws the response.
- The Tools section contains several tools - such as TS parameters calculation, Resonance frequency variation, Added resistance to Re / Change in Mms, Air core inductor, etc.
- Clicking the counter above the listbox displays a full parameter list.
- You can simulate three types of enclosures: Closed, Vented, and 4th-order Bandpass. The Closed box type also includes a Linkwitz Transform tool.
- The txt button in the header shows a list of the main parameters, ready to be copied into a file or onto a website.
- Blue labels can be clicked - such as Bl to Mpow
- On the Formulas page, you can see relationships between parameters and copy them into Excel.
