Saracon Sampling Rate Conversion Software

"Saracon is not only the world's best audio sample rate converter (cross
platform!). It's also a great batch renamer, format converter, interleaver, de-interleaver, word length reducer and all-round utility tool!"
Bob Katz, Digital Domain, USA

Saracon - a versatile multichannel file format and sampling rate conversion tool of utmost sonic quality and unprecedented conversion speed. All standard sampling rates between 44.1kHz and 384kHz are supported, including DXD and DSD. DSD in both 2.8224 MHz and 5.6448 MHz variants. POW-R dithering is also standard procedure of course.

Saracon runs on Windows or OSX platforms and comes in two variants: SARACON and SARACON-DSD. The latter also supports DSD conversion.

The Super Audio Center recommends Saracon-DSD for DSD conversion.

SARACON is a batch processor working on source and destination files. It does not support streaming modes.
