Recently, the MPEG Audio standardization group started a new work item on Spatial Audio Coding. This new approach allows for a fully backward compatible representation of multi-channel audio at bit rates that are only slightly higher than common rates currently used for coding of mono / stereo sound. This paper briefly describes the underlying idea and(More)
Recently, technologies for parametric coding of multi-channel audio signals have received wide attention under the name of " Spatial Audio Coding. " In contrast to a fully discrete representation of multi-channel sound, these techniques allow for a backward compatible transmission at bitrates only slightly higher than rates commonly used for mono / stereo(More)
Pneumococcal meningitis is a serious infection of the central nervous system (CNS) with high fatality rates that causes reduced psychomotor performance, slight mental slowness, impairments in attention executive functions and learning and memory deficiencies. Previously, we demonstrated a correlation between memory impairment and decreased levels of(More)
Recently, a new approach in low bitrate coding of stereo and multi-channel audio has emerged: Spatial audio coding permits an efficient representation of multi-channel audio signals by transmitting a downmix signal along with some compact spatial side information describing the most salient properties of the multi-channel sound image. Besides its impressive(More)
Sleep deprivation has been regarded as a beneficial treatment modality for about 60% of patients with Major Depressive Disorder. Unfortunately, however, more than 80% of the improved patients relapse into depression after the next night of sleep. In the present study we tried to prevent relapses into depression after successful total sleep deprivation (TSD)(More)
Total sleep deprivation (TSD) exerts beneficial but only transient effects on mood in approximately 60% of the patients with a major depressive disorder (MDD). The positive effect of TSD is generally reversed after the next night of sleep. A pilot study of our group indicated that a consecutive one week phase advance of the sleep phase stabilized mood in(More)
