Super Audio CD is a new audio carrier, aimed at being the successor to CD,
which uses `Direct Stream Digital' (DSD) as audio format. DSD is
essentially a 1-bit bit stream, and, hence, Sigma Delta Modulation (SDM)
is a critically important technique for Super Audio CD. In this
presentation, some issues will be discussed which are important for
applications of SDM in high end audio applications. Also, various design
methods for SDMs will be discussed, including some recent developments
which are aimed at improving the audio performance of a SDM. Also, a model
will be discussed which explains some of the non-linear behaviour of 1-bit
SDMs, such as idle tone behaviour and distortion.
If time permits, and if there is interest, the general concept of Super
Audio CD can also be discussed.
