About PCM files
PCM (Pulse Code Modulation) is the standard digital audio format that represents sound waves as numerical values. It's uncompressed, maintaining perfect audio quality but creating large file sizes. PCM serves as the basis for formats like WAV and CD audio, widely used in professional recording and broadcasting. Though not space-efficient, its lossless nature makes it ideal for high-fidelity audio applications where quality preservation is crucial.
About CAF files
The CAF (Core Audio Format) is an audio file format developed by Apple for professional audio applications. It supports high-quality audio with flexible compression options and can store multiple tracks, metadata, and effects. CAF is widely used in Apple's audio production tools like Logic Pro and GarageBand due to its reliability and large file size support. While not as common as MP3 or WAV, it is valued for advanced audio editing and recording needs.
