How do I convert an OPUS file to MAT4?

Upload your OPUS file, select MAT4 as the output format, adjust sample rate or bit depth if needed, and click Convert. Once done, download the .mat file and import it into MATLAB with load('audio.mat').

What is the difference between OPUS and MAT4, and why would I convert?

OPUS is a lossy audio codec optimized for compression and streaming. MAT4 (MATLAB v4) is a matrix file format for numerical analysis. Converting OPUS to MAT4 lets you import audio as a numeric array in MATLAB for signal processing, FFT, or AI research.

How does the conversion preserve audio attributes like sample rate and channels?

The decoder extracts PCM samples from OPUS and stores them in a MAT4 matrix. Sample rate and channel count are saved as variables. Bit depth is normalized to 16-bit or 24-bit. Because OPUS is lossy, the recovered samples are not identical to the original pre-compressed audio.

Is OPUS-TO-MAT4 free to use?

Yes, OPUS-TO-MAT4 on LetsConvert is 100% free with no registration or hidden fees required.
