Quality & Fidelity

Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. M4A Audio may clip extreme values. AIFF Audio maintains the complete dynamic range. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the AIFF Audio format supports it. Format-exclusive metadata fields that have no equivalent in AIFF Audio are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality M4A Audio input produces an excellent AIFF Audio output. Since the target format is lossless, output quality matches your input exactly.

Audio conversion from M4A Audio to AIFF Audio focuses on preserving sonic fidelity while adapting to the target format's characteristics. Converting lossy M4A Audio to lossless AIFF Audio preserves your current audio quality without further loss — useful for archiving your existing collection, though it won't restore frequencies already removed. Sample rate, bit depth, and channel layout are preserved when supported by the target format.

Important: Converting from lossy M4A to lossless AIFF does not restore previously discarded data. The output perfectly preserves your current file quality without adding further degradation, but quality lost during the original M4A encoding cannot be recovered.
