AIFF stores uncompressed PCM audio, which works out to roughly 10 MB per minute at CD quality. Converting to a compressed format like MP3 or a lossless codec like FLAC reduces the size if storage or upload time is a concern.

Most modern Windows media players and audio editors can open AIFF files, although WAV is the more common uncompressed format on that platform. If a specific program rejects the file, converting it to WAV preserves the audio exactly.
