An extended-run-length coding tool called zero compaction is proposed in this paper. The proposed coding tool is far more efficient and generates significantly better results than traditional run-length coding when a certain type of data appears in the middle stage of our lossless audio compression systems. The zero-compaction technique has been integrated into our lossless audio coding scheme. When tested on seven sets of standard audio files from the ISO, the inclusion of zero compaction improved the average compression rates of systems by more than 1% in all cases. In addition, the simplicity and good performance of zero-compaction shave up to 4% from the total encoding time.
