About the formats
WMA · Windows Media Audio
WMA is Microsoft’s legacy audio format. Many modern phones, Macs and media players no longer support it.
WAV · Waveform Audio
WAV is uncompressed audio, used for recording, editing and audio production. Files are large but lossless.
The conversion runs on your device using FFmpeg compiled to WebAssembly. You can adjust: sample rate, channels, normalise loudness, start at, end at.
