How do I convert an AU file to SPHERE?

Upload your AU file to our converter, choose SPHERE as the output format, and click Convert. The tool automatically reads the AU header, preserves the sample rate and channel count, and encodes to SPHERE with PCM 16-bit audio. You'll get a download link within seconds.

Why would I need to convert AU to SPHERE?

SPHERE is a standard format in speech research, widely used in corpora like TIMIT. Converting AU to SPHERE ensures compatibility with speech analysis tools and machine learning pipelines. Unlike AU's frequent u-law compression, SPHERE often uses uncompressed PCM, making the file ready for precise signal analysis.

What audio attributes are preserved during AU to SPHERE conversion?

Our converter preserves sample rate, bit depth, and channel configuration. If your AU contains u-law encoded audio, it is converted to linear PCM, which may increase the file size but prevents further lossy compression. Metadata such as annotation comments in the AU header are not transferred because SPHERE uses a separate header structure.
