How do I convert an AAC file to LU using LetsConvert?

Upload your AAC file, select LU as the output format, choose the desired sample rate and bit depth (44.1kHz/16-bit for CD quality), then click Convert. The tool will decode the AAC data and encode it into a lossless LU container. Download the LU file when ready.

Why should I convert AAC to LU instead of keeping AAC?

AAC is a lossy codec that discards audio data to reduce file size, while LU is a lossless format preserving every detail from the source. This makes LU ideal for professional editing, archival storage, and audiophile listening, as it ensures no additional generational loss during editing.

What happens to the audio quality when converting from AAC to LU?

Since AAC is lossy, the conversion cannot restore information already removed during AAC encoding. However, LU encodes the decoded AAC audio without further degradation, meaning the converted file retains the exact audio data present in the original AAC file. Any metadata like album art or tags will be preserved during conversion.
