SUMMARY

This discussion focuses on using MATLAB to play a music file upon the convergence of a calculation. The user references the audioplayer function and provides an example using Handel's "Hallelujah Chorus" with the commands load handel;, player = audioplayer(y, Fs);, and play(player);. The user seeks clarification on implementing this functionality in their non-linear least squares problem, emphasizing the need for the correct wavefile and sample rate parameters.

PREREQUISITES
  • Familiarity with MATLAB programming
  • Understanding of audio file formats and sample rates
  • Knowledge of non-linear least squares optimization
  • Basic usage of MATLAB functions such as load and sound
NEXT STEPS
  • Explore the MATLAB audioplayer documentation for advanced audio playback options
  • Learn about MATLAB's load function to handle different audio file formats
  • Investigate techniques for detecting convergence in non-linear least squares problems
  • Experiment with creating custom audio files in MATLAB using the resources at MATLAB music creation
USEFUL FOR

MATLAB users, data scientists, and engineers working on optimization problems who want to integrate audio feedback into their calculations.

I would like to run a calculation so that when it has converged, a song will play... to alert me from the other room (for example).

I found this but can't quite put it together? Their example was:

Examples

Load and play a sample audio file of Handel's "Hallelujah Chorus:"

load handel;
player = audioplayer(y, Fs);
play(player);

I'm not clear on this... Okay, so any explanations greatly appreciated; also, you are welcome to suggest a tune to play once convergence is met (its a non-linear least squares problem, maybe it will inspire the tune :O)
 
Physics news on Phys.org
sound(y,Fs)

where y is the wavefile you want to play and Fs is the sample rate.

you can write your own music:

or you can load the handel edxample that comes with matlab, which comes with its own "y" and "Fs"

load handel.mat;
sound(y, Fs);
