A Audio Codec Based on Adaptive Transform Coding with Extended Lapped Transform
This paper presents a new transform coder called tlie Lapped Transform Coder (LTC) for high fidelity coding of music signal. The word "Extended" contained in tlie name of this coder is simply because we adopt the Lapped Transform in tlie coder. It is also found that ELT with larger block size and statistics block number provides a better Signal-to-Noise (SNR) ratio in our studies. Thus, we used the ELT with overlapping factor of four in the LTC with the block size 64 and the statistics block number 64. The performance of the LTC is good and it has many favourable results for practical implementation.
