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:
You can download the program from Softpedia or directly from the audioweb.cz homepage, where an updated driver database file is also available.
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:
- There is a large driver database included, mostly up to date. If you want to add a new driver to carry out a simulation, only six parameters are required: Qms, Qes, fs, Mms, Dd, and Re. The rest is calculated. The small hidden "=" symbol in the lower-right corner serves to rename records.
- The Up/Down keys change the numeric value by +/-1. For fine-tuning, hold down the Shift or Ctrl key beforehand.
- Double-clicking on the form will expand/contract the window; double-clicking in the graphs will quickly draw the response.
- There are a number of tools in Advanced options, for which I might write a simple tutorial later - such as TS parameters calculation, Shift of resonance frequency, Added resistance to voice-coil, Added mass to cone, Air coil, etc.
- Clicking on the counter above the listbox shows a detailed list of drivers.
- There are three types of enclosures you can simulate - Closed, Vented and 4th-order Bandpass. The closed box also includes a Linkwitz transform tool.
- The txt button in the header shows a list of main parameters ready to be copied to a file or a website.
- Blue labels can be clicked on, such as Dd to Sd, litres to cubic feet or Bl to Mpow (which is Motor power-factor - you can see it on loudspeakerdatabase.com or in Punktkilde datasheets as a Bl/sqrt(Re) constant; more on Claus Futtrup's website).
- On the Formulas page, you can see relationships between parameters and copy them into Excel.
