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.
AIFF · Audio Interchange File Format
AIFF is Apple’s uncompressed audio format, the Mac equivalent of WAV, used in music production.
The conversion runs on your device using FFmpeg compiled to WebAssembly. You can adjust: sample rate, channels, normalise loudness, start at, end at.
