Abstract

We have developed the MPEG-2 AAC (LC profile) Encoder in the professional authoring systems for Electric music distribution (hereafter EMD). The encoders for professional use are required higher quality sounds to express music contents correctly than the encoder for consumer use. So we have researched a few quantization methods in MPEG-2 AAC encoding algorithm that we think it effect the sound quality seriously and we have developed new methods to get the high quality sounds. In this paper, we described the new methods and the construction of the encoder system for the EMD using them.
