I want to record landline calls at my desk with one-click or similar. For example, say I get a work call that I want to record, I just hit one key on my Microsoft Natural Ergonomic 4000 keyboard or one button on my multi-button Logitech mouse and the Mac (Mac Mini running El Cap/OS 10.11) just starts recording. No steps, just one button or keystroke, regardless of what application is open or running.
I currently have a landline phone recorder adapter, which outputs a standard 3.5mm jack. I have an Olympus digital recorder, which works fine. But I want to remove the Olympus from the system and just record directly to my Mac's hard drive using something like Quicktime to record the audio calls. Now I have plugged the adapter's 3.5mm output into the Line In input on the back of my Mac Mini. It records in Quicktime and Audacity fine, but I want it to open either audio app and start recording with one-click, etc.
How do I do that? Keyboard Maestro the best way? Anything cheaper or free? Thanks.
