Modeling mathematical representation for music signal

Click For Summary
SUMMARY

The discussion focuses on modeling the mathematical representation of music signals, specifically from a guitar recording captured in a time domain. The user seeks methods to analyze the signal, potentially using piecewise functions to separate components like Attack, Decay, Sustain, and Release (ADSR). A key suggestion is to explore Fourier transformations, which provide a comprehensive approach to signal analysis and representation in the frequency domain.

PREREQUISITES
  • Understanding of time domain and frequency domain concepts
  • Familiarity with ADSR envelope in audio signals
  • Knowledge of Fourier transformations and their applications
  • Experience with music production software for signal recording
NEXT STEPS
  • Research Fourier transformations and their implementation in audio signal processing
  • Learn about piecewise functions and their application in modeling ADSR envelopes
  • Explore software tools like MATLAB or Python libraries for signal analysis
  • Investigate advanced signal processing techniques for music representation
USEFUL FOR

Musicians, audio engineers, and signal processing enthusiasts looking to deepen their understanding of mathematical modeling in music signals.

Hello there I am sorry if this sounds silly or out dated

i want to ask anyone, how can i model the mathematical representation from music signal(time domain).

lets say i recorded the signal from guitar through my music production software and print screen that signal as shown here upload.wikimedia.org/wikipedia/commons/4/4d/C_Envelope_follower.png

how do i model the mathematical representation for that graph? do i need to zoom in and separating that signal and find it one by one using piecewise function(since it is ADSR)?

or is there another way using computer software in signal processing to obtain the mathematical representation?

please help me
thanks

Look up Fourier transformations. This is a bigger chapter and cannot be answered quickly.
