What is CDDA?

CD Digital Audio, raw audio track from compact discs — stored as audio/x-cda — uses lossless encoding to handle cd ripping, audio archiving, high-fidelity audio. Typical file sizes: varies by content.

What is AAC?

AAC (Advanced Audio Codec) is a modern lossy audio format that provides better sound quality than MP3 at the same bitrate.

When Should You Use CDDA vs AAC?

CDDA vs AAC: Key Differences

• •CDDA and AAC diverge on compression: lossless compression for the source, lossy compression for the target.
• •Converting from CDDA to AAC changes compression type: lossy source becomes smaller but with some quality tradeoff.
• •Transparency: N/A — converting from CDDA will merge transparency into a solid background
• •File sizes: CDDA files typically range N/A and AAC files Slightly smaller than MP3 at equivalent quality.
• •Use case fit: CDDA targets cd ripping, audio archiving, high-fidelity audio and AAC targets streaming, mobile audio, youtube — your choice depends on which workflow stage you are serving.
