24-bit resolution A bit depth used for high-quality audio playback.
32-bit floating point resolution An extremely high-resolution bit depth used for lossless
computation of audio or video data.
35 mm A standard motion picture film format. This may be cropped during projection
to create widescreen aspect ratios such as 1.66 or 1.85, or filmed and projected
anamorphically for an aspect ratio of 2.40.

Apple, based on Electronic Arts IFF (Interchange File Format). Like WAVE files, AIFF files

information. An extension of the AIFF format, called AIFC, can store compressed audio
data.
