How do I convert CDDA audio from an audio CD to AAC?

Insert the CD, select CDDA tracks in the source tab, choose AAC as the output format, pick a bitrate (e.g., 256 kbps), and click Convert. The tool extracts the RAW PCM from each track and encodes it to AAC with the chosen settings, preserving tags like track name and artist.

Why should I convert my CDDA collection to AAC instead of keeping WAV/FLAC?

CDDA is uncompressed PCM, using 1411 kbps (about 10 MB per minute). AAC at 256 kbps cuts file size by ~80% while sounding transparent on most audio equipment. It's also universally supported by iTunes, iPhones, Android, and streaming platforms, so you can keep your music library compact and compatible.

What happens to the audio data (sample rate, bit depth) when converting from CDDA to AAC?

The conversion re-encodes from 44.1kHz/16-bit PCM into AAC's perceptual codec. The sample rate stays at 44.1kHz by default, but the bit-depth becomes variable as conforms to AAC's compression algorithm. To preserve maximum fidelity, choose a high bitrate like 320 kbps or VBR; the tool also copies ID3 tags automatically.

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