How do I convert AU to F64 files?

Upload or select your AU file, choose F64 as output format, set optional parameters like sample rate or bit depth, and click Convert. The tool decodes the AU codec (e.g., µ-law, A-law, PCM) and writes raw 64-bit IEEE 754 floating-point samples, preserving the original channel layout and time domain.

Why should I convert AU to F64 instead of keeping AU?

AU often uses compressed codecs like µ-law or A-law, which reduce fidelity. F64 stores audio as uncompressed 64-bit floating-point samples, providing huge dynamic range and no quantization distortion—ideal for audio analysis, high-end mixing, or long-term archival. Also, many modern DAWs and scientific software (e.g., MATLAB, Python) handle F64 raw files natively.

What audio attributes are preserved when converting AU to F64?

The converter maps the decoded PCM data from AU to F64 without dithering or resampling. Sample rate, number of channels, and sample timing are retained exactly. However, metadata like album tags or cover art in AU (if any) are not carried over to the raw F64 file, as F64 is a container-less raw format. You may need to note these separately.

Yes, AU-TO-F64 on LetsConvert is 100% free with no registration or hidden fees required.

Yes! AU-TO-F64 works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?
