Suppose you are to compress by 74%. Then fft () and extract and retain (100-74) = 26% of the fft coefficients. You will have removed 74% of the information, so that will be compression. To reconstruct the signal, know the original number of samples, and create a vector of zeros that long, and write the saved coefficients into that vector in the ...
Dynamic range compressor - MATLAB

Compare Limiter and Compressor Applied to Audio Signal. Compare the effect of dynamic range limiters and compressors on a drum track. Create a dsp.AudioFileReader System object and a audioDeviceWriter System object to read audio from a file and write to your audio output device. To emphasize the effect of dynamic range control, set the operational threshold of the limiter …

So, we can simply use MATLAB's resample function to resample the original data, then prepend the encoded audio file with the sample rate. Of course, the threshold frequency varies for different files; in this case, we have a compression ratio of 53% of the original data size, since the threshold frequency 12750Hz is 53% of 24kHz.
Audio Toolbox - MATLAB & Simulink - MathWorks
https://www.mathworks.com/products/audio.html
Audio Toolbox™ provides tools for audio processing, speech analysis, and acoustic measurement. It includes algorithms for processing audio signals such as equalization and time stretching, estimating acoustic signal metrics such as loudness and sharpness, and extracting audio features such as MFCC and pitch.
