Abstract
An audio system comprises an audio source terminaland a audio playback terminalconnected to each another by a wireless data linkThe source terminalcomprises a source computerand a cellular modemThe playback terminalcomprises a playback computerhaving an internal processorand an audio processorConnected to the processoris a cellular modeman audio transducerand a user controlData relating to audio components, representing different services, is stored at the source terminalwhere it is spatially processed and transmitted to the playback terminal. At the same time, each individual audio component is transmitted at a lower bit-rate than the spatially processed data, to the audio source terminalwhereafter it is spatially processed. Although the low bit-rate transmission causes a loss of audio quality, the positional data remains unaffected. Accordingly, when played, the combination of a high quality signal with low three-dimensional audio positional accuracy, and a set of low quality signals with high three-dimensional audio positional accuracy, results in restoration of the human perception of three-dimensional position to the degraded three-dimensional audio signal.
