Abstract:
A multi-band limiter, a sound recording apparatus, and a program are provided having a multi-band limit function with a flat frequency characteristic while removing a dead zone of the multi-band limiter. A multi-band limiter is provided including an overlap filter unit (200) that divides an input sound signal into low-band, middle-band, and high-band components such that the components overlap each other between adjacent bands, limiters (202, 204, 208, 210, 214, 216) that apply a limit process to limit a level in each band, trimming filter units (206, 212, 218) that apply a trimming process to trim an overlapping signal component in each of the limit-processed components, and an adder (220) that combines and outputs the trimming-processed components.
