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