How do I convert an AU file to MAT5 format?

Upload your AU audio file to LetsConvert, choose MAT5 as the target format, and click Convert. The tool decodes the AU container, extracts raw PCM samples along with sample rate, bit depth, and channel count, then writes a MATLAB v5 MAT-file. You can download the resulting .mat file and load it directly in MATLAB using the `load` command.

Why convert from AU to MAT5 instead of keeping the audio file?

AU is a container for compressed or uncompressed audio, typically used in Unix/NeXT environments. MAT5 is a binary data format used by MATLAB to store variables, including arrays. Converting AU to MAT5 lets you load audio samples as a numeric matrix in MATLAB for signal processing, statistical analysis, or training machine learning models—something you cannot do directly with a .au audio file.

How does the conversion handle audio attributes like bit depth and sample rate?

The converter extracts the audio stream and stores it as an N-by-C matrix of doubles or int16/int32 values, depending on the original bit depth. The sample rate and number of channels are stored as separate MAT-file variables (e.g., `fs` and `nchannels`) to ensure the exact timing and spatial layout of the original AU recording are preserved. Lossy compression inside the AU file is decoded to raw PCM before saving, so no additional loss is introduced.

Is AU-TO-MAT5 free to use?

Yes, AU-TO-MAT5 on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Yes! File privacy and security are guaranteed. Basic conversions run locally in your browser. Files sent for server processing are automatically deleted within 1 hour.

Does this converter work on mobile phones and tablets?

Yes! AU-TO-MAT5 works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
