Description
This proposal offers SPIHT compression for near-lossless and strictly lossless compression of acoustic array data. We show in tests on publicly available acoustic data that the requirements of 5:1 compression ratio and almost zero distortion are satisfied by 1D-SPIHT coding of the single stream output of the acoustic array. Because 1D-SPIHT has low complexity in addition to high efficiency, the coding-decoding latency is almost negligible. .Also proposed for testing is a two-dimensional SPIHT coder for inter-channel compression, if separate channel data are made available. In order to combat degradation in reception from an error-prone channel, we propose methods for building error-resilience and error-protection coding into the SPIHT code-streams .
