How do I convert CDDA to AU?

Upload your CDDA file (raw 44.1kHz/16-bit PCM) to LetsConvert, select AU as the output format, choose between lossless PCM AU or compressed μ-law, and click Convert. Download your AU file instantly—no software installation needed.

What happens to the audio data during CDDA to AU conversion?

When converting CDDA to AU, the 16-bit stereo PCM audio is preserved bit-for-bit if you select the PCM encoding. If you choose μ-law, each 16-bit sample is compressed to 8-bit using μ-law companding, which reduces file size by roughly half. The sample rate remains unchanged unless you explicitly set it differently, so the original timing and stereo image remain intact.
