PROBLEM TO BE SOLVED: To provide a sound signal synthesizer capable of creating a novel sound signal while allowing the influence of sound signals prior to synthesizing to remain in synthesizing a plurality of the sound signals, and a sound signal synthesizing/reproducing apparatus capable of reproducing the sound signals simultaneously with synthesizing the same. SOLUTION: A block read means 10 reads the plurality of the sound signals in sound block unit consisting of a prescribed number of samples from a sound signal memory section 61 and a frequency conversion means 20 applies Fourier transform to the sound blocks read from the respective sound signals to obtain spectral blocks. A block read means 30 generates synthesized spectral blocks by synthesizing the spectral blocks obtained from the respective sound signals and generates the synthesized sound blocks by Fourier inverse transformation. The generated synthesized sound blocks are sequentially outputted by an output means 50 and the synthesized sound signals are recorded in a synthesized sound signal memory section 60.
