Having a little play with a CA3080E operational transconductance amplifier to give classical music some serious tremolo.

great job Julian! this sort of thing could become useful for when i decide to get round to making the all in one super effects home-made guitar pedal 😀
Nice one – you used a bunch of electronics to emulate a skipping CD 🙂 Would make a cruel trick to play on the LP buff – stick this circuit between their turntable and the amp when they're out of the room and have a bit of fun with digital potentiomeneters, and a 433 mhz RF remote 🙂
Can you teach how the breadboards work?
Nice little experiment. I liked the sound effect.
Thank you Julian for this review on the use TOA. Now I can't wait to try that on my fender guitar.
I really like that you're playing with audio, as it co-insides with my own set of projects I'm planning out. Have you done any stuff with Arduino and audio? And incidentally anything with ESP8266 or RF24 involving streaming audio?
new thumbnail style and title with your name on it is not good,
Cool. I want to use a couple of these OTA for a circuit to vary white noise input to make a crashing wave sound circuit. I figured I would make 2 channel VCA with random modulation frequency in each to make it sound natural with a third channel as low level background white noise. Very timely circuit. Thanx.
A concept that might improve the original schematic would be to change from a linear gain control signal to an exponential one (proportional to the drive signal as an exponent). I think you might find cookbook, voltage to exponential current output circuits in many opamp manuals. I may be able to help with that.
could you tell me where to find that vocoder schematic?
I've been a little disinterested in this project until now. Mainly, love music have no idea how its constructed. But todays video made me sit up and listen. Well done Julian for a most interesting post.
It really sounds like buffer underrows like in the good old Pentium 90 times with SoundBlaster 16 and having the CPU under full load while playing the first ever envoded MP3 file. 😀
