Sound processor, sound processing method, and computer program product

摘要

According to one embodiment, sound processor includes: communication module; outputting module; recording module; display; input module; controller; and calculating module. The controller (i) displays, on display, message prompting user to move a sound input device to position proximate to speaker, (ii) causes the outputting module to output the test sound and causes the recording module to record first sound, (iii) displays, after the first sound is recorded, on the display, message prompting the user to move the sound input device to listening position, and (iv) causes the outputting module to output the test sound and causes the recording module to record second sound. The calculating module finds a first frequency characteristic of the first sound and a second frequency characteristic of the second sound, and calculates, based on a difference between the first and second frequency characteristics, a value for correcting the second frequency characteristic to a target frequency characteristic.

主权项

1. A sound processor comprising:
a communication module configured to communicate with a sound device; a test sound outputting module configured to cause the sound device to output test sound through the communication module; a recording module configured to record sound collected with a sound input device; a display configured to display a message; an input module configured to receive a user input; a controller configured to (i) display, on the display, a first message prompting a user to move the sound input device to a position proximate to a speaker of the sound device so as to record first sound, (ii) cause the test sound outputting module to output the test sound in accordance with a user input made with respect to the input module in response to the first message and cause the recording module to record the first sound, (iii) display, after the first sound is recorded, on the display, a second message prompting the user to move the sound input device to a listening position so as to record second sound, and (iv) cause the test sound outputting module to output the test sound in accordance with a user input made with respect to the input module in response to the second message and cause the recording module to record the second sound; and a calculating module configured to find a first frequency characteristic of the first sound recorded with the recording module and a second frequency characteristic of the second sound recorded with the recording module, and calculate, based on a difference between the first frequency characteristic and the second frequency characteristic, a correction value for correcting the second frequency characteristic to a target frequency characteristic.
