| 摘要 |
The present invention provides a signal processing apparatus, a signal processing method and a program for outputting a high-quality coded string. A signal processing apparatus according to an embodiment of the present invention includes a normalization coefficient information increasing/decreasing circuit 12 for modifying normalization coefficient information of a signal component of a frame and normalization coefficient information of a primary additional signal component according to a normalization coefficient information primary increase/decrease amount, and an additional signal component normalization coefficient information increasing/decreasing circuit 14 for modifying normalization coefficient information of a secondary additional signal component, which is a copy of the primary additional signal component, according to a normalization coefficient information secondary increase/decrease amount. |
