I've been trying to learn AKABAK 3 recently and found the lack of having all learning aids in one location quite a hinderence. Example my install did not seem to carry the SP20 sealed enclosure files and I did not notice the 'videos' link on the AKABAK site.
So here I propose to list all useful learning aids for AKABAK. If you have some to share, please do!
1) SP20 sealed enclosure video tutorial - VIDEOS HERE Files can be found in the 'No Installer' ZIP file here
2) Watch all the other AKABAK VIDEOS, they are only short.
3) Panson_hk examples on this forum. Post 2 and Post 11 . Download the files and study the elements in use.
4) Simulating a waveguide by Austin Mys VIDEO HERE. (Check out his other good videos). You will need a CAD software to draw your waveguide like Fusion 360. I have dumped an example project file attached WG44.zip.
5) Waveguides can also be generated by the software ATH4 HERE that outputs ABEC (AKABAK compatible) project files. I found the tutorial for ATH4 HERE helpful in understanding AKABAK BEM, too.
A couple of tips for issues I struggled with:
Error: RPC server unavailable - The connection between AKABAK and VACS (the viewer program) is broken. Restart VACS and click the VACS icon in AKABAK to establish a connection.
VACS looks tiny in 4K resolution - Stick this 'manifest' file in the same directory as the VacsViewer_64.exe file (file name must match). Then start VACS manually then click the VACS icon in AKABAK to establish a connection.
Frequency response has roll-off - If you create a project in BEM using a mesh as 'driven' to represent a speaker, or use the 'diaphragm' component, or a 'pressure box' component, but do not link them to a LEM model (i.e. they act as ideal pressure sources with no T/S parameters) you will by default have a bass roll-off. Go to the menu 'Global' > 'Fixed Driving'. Set 'Weight' to 'Divide by jw'. At default the ideal pressure source has constant velocity, which means at low frequencies the 'driver excursion' is smaller. This setting sets a constant energy spectrum instead of constant velocity.
That's all I can think of for now. EDIT: Can't believe I forgot Panson's posts on this very forum! Added now.
