Abstract

For example, reverberation processing in consideration of sound quality can be performed. Provided is an information processing device including a training processing unit that generates training data by convolving a measurement signal representing acoustic characteristics collected by a same sound collection unit as a sound collection unit used for collecting an observation signal with a reference signal having sound quality and reverberation characteristics different from the observation signal, generates teaching data by adapting, to the reference signal, an average level and a delay value of a convolution signal generated by convolving a direct sound component of the measurement signal with the reference signal, and trains a learning model for performing reverberation processing of the observation signal collected by the sound collection unit by using the training data and the teaching data as input data.
