AIFF is Apple's audio format, developed for the Mac in 1988. WAV is its counterpart from Microsoft and IBM, created for Windows, and one of the most common audio formats. Both usually hold the same uncompressed PCM audio, so the sound can move from AIFF to WAV with nothing lost.

To WAV Converter turns whole folders of AIFF files into WAV in one drag and drop: for Windows software, and for editing, applying effects and mixing, where sound engineers choose WAV. Its automatic settings keep the quality, with no resampling or remixing, and all tags are transferred.

No quality lost

The default settings in Preferences / Format keep the quality. WAV Codec 'Automatic Selection' picks the PCM codec that matches the AIFF file's bit depth, and Sample Rate and Channels 'As Source' avoid resampling and remixing.
