dBpoweramp Aiff Codec (CDGrab.exe). The extension for this file type is ".aif" of ".aiff" when it is used on a PC. On a Mac, the file extension is not needed.
AIFF (Audio Interchange File Format) is a widely used, high-fidelity audio standard on the Apple Macintosh operating system. Also known as “Apple Interchange File Format,” it remains a top choice for creators who need uncompressed sound quality for music production, video editing, and professional workflows. This description helps users understand AIFF while supporting related long-tail keywords such as “best lossless audio format for Mac,” “high-quality audio editing workflow,” and “uncompressed studio-grade sound files.”
AIFF files use the “.aif” or “.aiff” extension on PC systems, while macOS identifies them using Type and Creator metadata instead of extensions. Inside each file, AIFF stores raw audio data, channel configuration (mono or stereo), bit depth, sample rate, and application-specific metadata that remains intact even when opened in different software.
The AIFC variant extends AIFF by allowing compressed audio within the same structure, though many early compression types are now replaced by formats like MP3, WMA, and OGG. AIFF also supports ID tagging, including album art and internal id3v2 tags compatible with iTunes for seamless organization across audio libraries.
