  • Page 7: The Codec Technology

    The Codec Technology The "ISO-MPEG Audio Layer 2 and Layer 3“ compression procedures developed by the Fraunhofer Institute and the Institut für Rundfunktechnik allow audio signals (even large amounts of data) to be reduced in real time and transferred without any subjective loss of quality. The digitised signals received in this form are compressed (encoded) to save on transmission bandwidth, time and cost.
