Ok, sounds like you're happy with scripting Airfoil. If you decide you'd like to try Airplay instead, you can use Apple Shortcuts (with KM if you want more control) to set the volumes of your various devices independently.
en.wikipedia.org NACA airfoilThe NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. The NACA four-digit wing sections define the profile by:
The key to getting this whole thing working is that TriggerCMD can run AppleScript locally on the Mac and AirFoil is fully scriptable with AppleScript and it can control AirPlay speakers and direct audio from apps running on the Mac to one or any combination of them (in perfect sync, too).
In that case YES. Create the script on your Mac and call it from the Pi using a shell_command that calls the script via SSH to your Mac. This would look a lot like the script above where I ssh into my ASUS.
Thank you for your help.
I have got Airfoil up and running in home assistant
using shell commands to BetterTouchTool then apple script to airfoil
controlling both speaker selection and input control
only thing left to do is work out volume control but that is for another day !
I have been working on these scripts for a while now and wanted to write a short post about them. My first script, the NACA four digit aerofoil script, quickly allows the user to produce an aerofoil using the parametric four digit standard with minimal amount of effort. The second script I wrote is an adaptation of this script to allow the user to import a predefined aerofoil from a database.
Both of these scripts can either be used to extrude into a straight wing or many aerofoils can be created and lofted together. However, when lofting, the end result occasionally didn't produce the correct results. I got by this by adding 3D splines between them and using them as loft guides. This became the most time consuming part of lofting a wing. Therefore I set about creating a feature that automatically drew splines between the aerofoils and then used the splines as guides.
These three scripts are now promoted on OnShapes website. I would be delighted to hear feedback, there is a forum post here that I use to communicate new additions and updates. The direct link to my script is here. Thank you for reading.
It was 2008 when I began as a summer intern at Pointwise. One of the first grids I generated was an O-Grid for an airfoil. The process was so repeatable that once I had learned Glyph I immediately began scripting the airfoil meshing process, the first step of which, was to generate the airfoil geometry. The very first script I wrote eventually became AirfoilGenerator.glf, the topic of this article.
For those unfamiliar with NACA 4-Series airfoils, they are created from a mean camber line and thickness distribution defined using four digits. The first number represents the maximum camber of the airfoil in percent chord. The second digit represents the maximum camber location. And the last two digits represent the maximum thickness at 30% chord. For example, a NACA 2412 has a maximum camber of 2% of the chord located at 40% of the chord with a maximum thickness of 12% of the chord located at 30% of the chord. NACA airfoils were meant for scripting!
Upon executing the script, a Tk GUI opens and prompts the user to specify the 4-Series designation and select from either sharp or blunt trailing edge options. With the airfoil designation and trailing edge type defined, click CREATE to generate the geometry in Pointwise.
