Learn About Sine Wave Separation and Sound Processing

[EebamXela]

Please forgive me, I don't really know how to properly ask my question, so I'll just do my best.

I want to learn how sound is processed. More specifically what math goes into figuring out what individual frequencies are within a single sound signal. Like if I had a recording of say 5 separate tones, how could I mathematically determine the individual frequencies and amplitudes?

I'm not sure what to even search for on google to learn more. Can someone please point me in the right direction? Thank you.

You should Google "Fourier Analysis" or "Fourier Transform." It sounds like that its what you are looking for.

It isn't easy. Here is a start.

Use MULTI-SIM or Pspice simulation software. Add 5 Sine waves with 5 different frequencies with 5 different amplitudes, you'll get one very weird looking wave. Run Fourier Transform of Multi-Sim on the weird wave pattern. The result will show 5 separate spikes on frequency axis with 5 different heights. They are the frequencies and amplitudes you used when added them together.

Your Fourier Math on paper will do the same thing.

Sure, I'd be happy to help! The process you are describing is called "sine wave separation" or "frequency analysis" in the field of sound processing. It involves breaking down a complex sound signal into its individual frequency components using mathematical techniques such as Fourier analysis or the Fast Fourier Transform (FFT). This allows us to identify and measure the amplitude and frequency of each individual tone within a sound recording.

There are many resources available online to learn more about this topic, including tutorials, articles, and video lectures. I would recommend starting with basic concepts such as waveforms, frequency, and amplitude, and then moving on to more specific techniques like Fourier analysis and the FFT. You can also try searching for terms like "sine wave separation tutorial" or "sound frequency analysis" on Google to find more specific resources.

I hope this helps get you started on your learning journey! Feel free to ask for clarification or additional resources if needed. Happy exploring!
