A chord

135

01:09:12

(Experiment, tuned to A4=440Hz)
This is an A Major chord, comprised of the musical notes A4, C#5, and E5.
Sine waves at these frequencies produce something close to a sine wave of 440Hz with amplitude modulation at a rate of 55Hz. As frequency halves, the note is transposed down one octave. Therefore, the amplitude of the signal is modulated by the frequency of the root note minus two octaves. My hypothesis here is that as more (fitting) notes are added to the chord, the AM signal will gradually become a 55Hz sine wave with an amplitude of 3V.

Can just hear it. Maybe ask EC to give us sound.

And in Stereo

It shouldn't be too difficult, there are already sound and etc. And harmonics,, etc. Etc. Apps. in the App. Market EC only needs to provide hooks ti link to them.

Fair enough. I'd personally want to see a piezo buzzer component or something like that.

Why not make use of the mobile microphone and speaker, and intriduce components for EC, ( mic. And speaker), as well as bring able to connect and feed the output voltages from our circuits to an existing sinthesisers apps.

Like Caustic?

Probably!

And even better, we would like EC, be able to send it's output via headphone connection to gitar amplifier aux. Input, so we can creat effects,, with our circuits we design... Wow why are EC socstatic and have no imagination?!!

Right? That's what I want for Crimbo. Audio-capable EveryCircuit.

Plus a frequency analyser. So it can display the side bands and lobes.. and want them now.

A talking EC with a synth. Component, so ee can make talking clocks and circuits.
