| 摘要 | In a sound processing device, an index value calculation unit calculates a first index value that follows change of a sound signal at a first following degree and a second index value that follows the change of the sound signal at a second following degree which is lower than the first following degree. An adjustment value calculation unit calculates an adjustment value effective to adjust a reverberation component of the sound signal based on difference between the first index value and the second index value. A reverberation adjustment unit applies the adjustment value to the sound signal. | ||

| 主权项 | 1. A sound processing device for processing a sound signal, comprising: a non-transitory storage medium storing a program; a processor, when executing the program, configured to: calculate a first index value that follows change of the sound signal at a first following degree and a second index value that follows the change of the sound signal at a second following degree which is lower than the first following degree;calculate an adjustment value effective to adjust a reverberation component of the sound signal based on difference between the first index value and the second index value; andapply the adjustment value to the sound signal. | ||
