Quality & Fidelity
Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. Speex Audio may clip extreme values. WavPack Audio maintains the complete dynamic range. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the WavPack Audio format supports it. Format-exclusive metadata fields that have no equivalent in WavPack Audio are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality Speex Audio input produces an excellent WavPack Audio output. Since the target format is lossless, output quality matches your input exactly.
Audio conversion from Speex Audio to WavPack Audio focuses on preserving sonic fidelity while adapting to the target format's characteristics. Converting lossy Speex Audio to lossless WavPack 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 SPX to lossless WV does not restore previously discarded data. The output perfectly preserves your current file quality without adding further degradation, but quality lost during the original SPX encoding cannot be recovered.
