(54) | Effect adding apparatus |
(57) When a plurality of effects are simultaneously applied to an input audio signal,
a plurality of effect- algorithms each for applying solely an effect to the input
signal are stored in a memory (2), and a plurality of combination-algorithms or combination-data
which represent combinations of the effects and orders in which effects are applied
to the input audio signal are stored in the memory. When one of the combination-algorithms
or the combination-data is selected, effect-algorithms included in the selected combination-algorithm
or combination-data are selectively read out from the memory. A program for applying
effects in a predetermined combination and order is written by CPU (1) based on the
read out effect-algorithms and combination-algorithm or combination-data. Receiving
the program, DSP (4) successively applies effects to the input audio signal in accordance
with the program. As a result, the present effector needs less memory capacity than
the conventional effector in which a number of programs consisting of combinations
of effect-algorithms are previously stored. |
