I am coding with basic HTML5 web audio. I sometimes however, have to code in class, or a place where sound can't be played.
Is there an application that shows the output signal of the speakers on the OS level (OSX) ? (similar to the input signal meter of the mic in System Preferences).
Please keep in mind that the audio signal is coming LIVE from the browser ( I use chrome preferably, and ff on occasion ).
Part of the challenge here is that I am mapping animations to the sound, and am trying to match them in time, and if I see when there is sound, I can know if the animation is timed correctly. I am also trying to have visual feedback REGARDLESS of where the audio signal is coming from, simply put, I want to gain access to the voltage being supplied to the speakers, although in this case if there is an addon to Chrome or FF I will be happy with application specific solutions.
The similar question here only addresses audio files, not live audio from another application.
