BITPERFECT

With the Audiophilleo, it's easy to confirm that the digital data flowing from the computer to the Audiophilleo is a bit-for-bit exact copy of the original.

Software media players and operating systems control how music files stored and streamed. Sometimes, the audio “stack” inside the operating system changes the audio data in ways that may be difficult to detect. Such alterations include sample rate conversion, dithered volume controls, and automatic level matching, which can occur on playback, or when importing files into the media library.

Just play the BitPerfect test files (a free download from the Audiophilleo website) and the Audiophilleo will immediately validate bit-perfect transmission. If it isn’t bit-perfect, it’s generally a simple matter to adjust the media player or operating system settings appropriately. The Audiophilleo1 display also shows the magnitude of any errors.
