About WMA

WMA is a proprietary audio format developed by Microsoft. It offers both lossy and lossless compression and was designed to compete with MP3. WMA is supported by Windows devices and software but less so by other platforms.

About SPX

SPX is an audio file encoded with the Speex codec, which is designed for compressing speech rather than music. It offers low bitrates and good voice clarity, making it suitable for VoIP, podcasts, and internet telephony. SPX is now largely replaced by Opus.
