Abstract:
A head related transfer function generation apparatus includes a first input unit that inputs a first head related transfer function generated in a first measurement environment, a second input unit that inputs a second head related transfer function generated in a second measurement environment, and a transform normalization processing unit that normalizes a first gain of the first head related transfer function represented in frequency-axis data with a second gain of the second head related transfer function represented in frequency-axis data and also calculates a square root thereof.
