The MPEG-4 Low Delay Advanced Audio Coding (AAC-LD) scheme has recently evolved into a popular algorithm for audio communication. It produces excellent audio quality at bitrates between 64 kbit/s and 48 kbit/s per channel. This paper introduces an enhancement to AAC-LD which reduces the bitrate demand by 25-33%. This is achieved by adding both a(More)
Low delay perceptual audio coding has recently gained wide acceptance for high quality communication. While common schemes are based on the well-known Modified Discrete Cosine Transform (MDCT) filterbank, this paper describes novel coding algorithms that, for the first time, make use of dedicated low delay filterbanks, thus achieving improved coding(More)
Textiles are omnipresent in our daily life. Their combination with microelectronics will lead to completely new applications realizing elements of ambient intelligence. In this paper, a textile-based large-area sensor network integrated into a carpet is presented: Based on a network of simple information processing elements with integrated sensors or(More)
