How SPX Handles WMV Data
Quality in this conversion depends primarily on your source file. A high-quality WMV Video input produces an excellent Speex Audio output. Xonvert defaults to high quality settings that keep file size reasonable without compromising perceivable quality. WMV Video encodes data using perceptual compression that prioritizes human perception. Speex Audio similarly focuses on perceptual quality. The conversion maps between these approaches intelligently. WMV Video's known limitation — very poor support on macOS, Linux and mobile platforms — is resolved when converting to Speex Audio, which offers excellent speech compression at very low bitrates.
