Claim 0:
1. An apparatus for decoding data segments representing a time-domain data stream, a data segment being encoded in the time domain or in the frequency domain, a data segment being encoded in the frequency domain comprising successive blocks of data representing successive and overlapping blocks of time-domain data samples, the apparatus comprising:
a time-domain decoder for decoding a data segment being encoded in the time domain;
a processor for processing one or more data segments being encoded in the frequency domain and output data of the time-domain decoder to acquire overlapping time-domain data blocks,
wherein processing the one or more data segments encoded in the frequency domain comprises applying an inverse modified discrete cosine transform; and
an overlap/add-combiner for combining the overlapping time-domain data blocks to acquire decoded data segments of the time-domain data stream.
