CFA (Conformed Audio) files are created with some of the applications included in the Adobe Creative Suite version 4 or later. Developed by Adobe Systems Inc., the suite is designed for video and audio editing, graphic design and web development. The applications that create CFA files are Adobe Premiere Pro, After Effects, Encore and Soundbooth. They're created by default each time an audio file is imported to a new project.

As the name of the format suggests, CFA files are conformed to a proprietary format owned by Adobe. They are also used for improving the performance of the applications above when working with audio data and when creating previews for waveform files. The new format is easier to access and to parse resulting in shorter processing times. Still, because of initial caching, users may encounter a short delay when importing audio data for the first time.

Since CFA files contain uncompressed audio data, they can become very large. This can be avoided by disabling caching. However, this will result in longer processing times for audio previews. CFA files are automatically created by the Adobe Media Encoder, a standalone component of the Adobe Creative Suite that comes with all the applications mentioned above. All programs that use CFA files reference the same cache.
