Aunque el formato AU es menos común en el uso diario en España y Latinoamérica, su presencia en sistemas heredados y entornos de investigación científica justifica su conversión a NIST, un estándar más robusto para datos acústicos. Esto es especialmente relevante en instituciones con historiales de investigación en procesamiento de señales.
About AU to NIST Conversion
Short answer: yes, you can convert AU to NIST online for free, and quality is well preserved with the right settings. Just upload your .au file to CocoConvert, pick NIST as the output, and click Convert. The whole process takes seconds.
Now for the details. AU is a widely used file format. NIST is a widely used file format. Converting between these two formats lets you convert between formats quickly.
Your AU file is decoded and re-encoded as NIST. Converting AU to NIST maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

Frequently Asked Questions
Is AU to NIST conversion free?
Yes. CocoConvert offers free AU to NIST conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is AU to NIST conversion?
Most files convert in 2–10 seconds depending on size. Large audio files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded AU file and the converted NIST file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting AU to NIST lose quality?
Converting AU to NIST maintains high quality with CocoConvert's optimised encoder settings.
Can I convert NIST back to AU?
Yes, CocoConvert supports NIST to AU conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
