SUMMARY

This discussion focuses on dividing a WAV file into segments using MATLAB. According to the MATLAB documentation, mono sound is imported as an m x 1 array and stereo as m x 2, where m represents the total number of samples. Users can segment the audio by manipulating these arrays and then re-saving the segments with the wavwrite function. This method provides a straightforward approach to audio segmentation in MATLAB.

PREREQUISITES
  • Understanding of MATLAB programming environment
  • Familiarity with audio file formats, specifically WAV
  • Knowledge of array manipulation in MATLAB
  • Experience with MATLAB's audio processing functions
NEXT STEPS
  • Research how to use MATLAB's wavread function for importing audio files
  • Explore MATLAB's wavwrite function for exporting audio segments
  • Learn about MATLAB's array slicing techniques for segmenting audio
  • Investigate audio processing techniques for enhancing segmented audio quality
USEFUL FOR

Audio engineers, MATLAB users, and anyone interested in audio processing and segmentation techniques.

According to the MATLAB documentation, MATLAB imports mono sound as an m x 1 and stereo as m x 2, where m is the total number of samples in the file:

Based on that information, you should be able to chop these up into shorter segments, and then re-save the resultant shorter segments using wavwrite:
