摘要
MP3是一种音频编码方案,它充分利用了人耳的听觉功能,最大限度的保持原来的声音效果。它的压缩比虽然很大,但音质却很好。本文介绍了应用STA015和CS43L43实现的音频电路设计及软件调试。
MP3 is a audio-frequency decoding scheme exploiting the properties of human ear and trying to maitain the original sound quality as far as possible. Although it has a high compressive ratio, the sound quality is very high. In this thesis, we will give the whole audio frequency circuit design and software adjusting process with using of STA015 and CS43L43.
