Sound processing device and method of outputting parameter of sound processing device

A sound processing device comprising:

• a memory configured to store computer-executable instructions;
• an input that receives an audio signal;
• and
• a processor configured to execute the computer-executable instructions stored in the memory to implement, the processor being received the audio signal from the input and obtained information of a parameter of the sound processing device corresponding to the received audio signal by using a trained model obtained by performing training by a predetermined learning model of a relationship among a training output sound of the sound processing device, a training input sound of the sound processing device, and a parameter of sound processing performed by the sound processing device, the parameter of the sound processing device being receivable by a user of the sound processing device;
• and
• an output that outputs the obtained information of the parameter of the sound processing device corresponding to the received audio signal,
• wherein:
• the training includes processing to train a relationship among a sound feature amount of the training output sound, a sound feature amount of the training input sound, and the parameter of sound processing performed by the sound processing device;
• and
• a calculator obtains a sound feature amount of the received audio signal, and obtains the information of the parameter of the sound processing device based on the sound feature amount and by using the trained model.
