Fidelity When Converting AU to MKA

Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. AU Audio preserves the full range. MKA Audio optimizes for typical display capabilities. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the MKA Audio format supports it. Format-exclusive metadata fields that have no equivalent in MKA Audio are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality AU Audio input produces an excellent MKA Audio output. Xonvert defaults to high quality settings that keep file size reasonable without compromising perceivable quality.

Audio conversion from AU Audio to MKA Audio focuses on preserving sonic fidelity while adapting to the target format's characteristics. Moving from lossless AU Audio to lossy MKA Audio reduces file size dramatically. At typical quality settings (128-256 kbps), the compression is psychoacoustically transparent — most listeners cannot distinguish the output from the original. Sample rate, bit depth, and channel layout are preserved when supported by the target format.

Compression trade-off: Your lossless AU source retains all original data. Converting to lossy MKA will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.

Bitrate consideration: For lossy MKA output, Xonvert defaults to a high bitrate setting that preserves audio transparency. You can adjust the bitrate in the settings panel — higher values mean better quality but larger files.
