WAV is an audio format developed by Microsoft and IBM for storing uncompressed audio data. It’s widely used for high-quality audio recording and editing. WAV files offer excellent sound fidelity and are compatible with nearly all audio software and hardware.
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.
Convert your .wav files to .spx right in your browser — no downloads, no installs. Everything happens securely in the cloud.
We never store your files permanently. Only you can access them, and they’re automatically deleted from our servers within 2 hours.
Turn your WAV files into SPX in just a couple of clicks. No registration, no limits — and it’s 100% free.
