摘要:
一種編碼調制的方法,用於將音頻信號編碼為L位元碼流,包括以下步驟:採樣音頻信號的當前採樣點獲取採樣數據N;計算當前採樣點的採樣數據N與前一採樣點的採樣數據N-1的差値d(N);判斷差値d(N)是否大於或者等於0;若差値d(N)大於或者等於0,則將差値d(N)的數値量化到M(2L-1

摘要(英):
A encoding modulation method for encoding audio signals to L-bit code streams includes following steps: sampling a current sampling point of the audio signals to get sampling data N; calculating a difference value d(N) between the sampling data N of the current sampling point and sampling data N-1 of a previous sampling point; judging whether the difference value d(N) is larger than or equal to 0, if d(N) is larger than or equal to 0, the difference value d(N) will be quantified to one of M (2L-1 < M < 2L) quantitative levels, and then the difference value d(N) will be encoded to one of M L-bit code streams based on its quantitative level. A related encoding modulation system is also provided.
