Digital audio processing is an emerging field of different standards for consumer and professional applications. Besides three main sampling frequencies (professional 48 kHz, consumer 44.1 kHz, broadcasting 32 kHz) two transmission formats have been established, namely a two-channel serial transmission format (AES/EBU format) and a multichannel audio digital interface (MADI). The interface techniques between these adopted standards will be discussed considering synchronization problems and the hardware complexity.
