Starting a tool with Applescript
Cheers,
I am trying to automate a few measurements, for now specifically i want to plot THD+N and THD vs. frequency.
I can create a signal generator tool with
and then set the properties I need and enable the signal I need, but when i try to start the tool with
it appears started, but does not output a signal.
If I manually stop and start it on the generator window, then it begins to output my signal. The documentation in applescript specifically states:
but I cannot see how I could actually start the output. I have the same issue trying to start the FFT analyzer.
any ideas?

it appears started, but does not output a signal.
If I manually stop and start it on the generator window, then it begins to output my signal. The documentation in applescript specifically states:
running (boolean) : Specifies whether the tool is currently running (sending or receiving data). Setting this value to 'true' (or using the start command on this object) does not start the selected device.
but I cannot see how I could actually start the output. I have the same issue trying to start the FFT analyzer.
any ideas?

Here's a sample script that picks the first available output device on the system, and outputs a 1 kHz tone on that device:
tell application "Electroacoustics Toolbox" activate create new project set devList to name of devices -- make sure there is at least one device connected to the system if (count of devList) is greater than 1 then -- make sure there is at least one device with output channels connected to the system -- pick the first output device found set foundOutputDevice to false repeat with i from 1 to count of devList set dev to device (item i of devList) if (count of output channels of dev) is greater than 0 then set foundOutputDevice to true exit repeat end if end repeat if foundOutputDevice then set sigGen to make new signal generator tool with properties {id:"siggen"} tell sigGen set selected device to dev set periodic signal A enabled to true end tell tell dev to start tell sigGen to start else display dialog "There are no devices with output channels available on your system. Please connect an audio output device and try again." end if else display dialog "There are no devices available on your system. Please connect an audio device and try again." end if end tell
