Generation loss — quality may degrade
WMV uses lossy compression, and so does WMA. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
What compression artifacts to expect
WMA lossy compression can produce smearing, loss of high-frequency detail. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
