Abstract: In a preparation step, raw material milk is prepared. In a lactose degradation step, at least part of lactose included in the prepared raw material milk is degraded using a lactose-degrading enzyme. The lactose concentration in the raw material milk in which lactose is degraded is not more than 2.5% by mass with respect to a total amount of the raw material milk. A lactic acid bacterium is added to the raw material milk in which at least part of lactose is degraded, and the raw material milk to which the lactic acid bacterium is added is fermented.

Abstract: An acoustic device configured to mix two or more music pieces is provided. The acoustic device includes a display controller configured to switchably display information related to audio mixing on a display device; and a reservation unit configured to set the music pieces to be mixed and a playback start point in each of the music pieces. The display controller is configured to switchably display on the display device a first screen, on which a first image indicating a playback status of a first music piece being played is moved based on a second image indicating a current playback point of the first music piece, and a second screen, on which the first image is fixedly displayed and the second image is moved based on the first image in accordance with the current playback point. The second screen includes a reservation-setting screen related to the reservation unit.

Abstract: The acoustic device includes: an operator; a state switching mechanism that performs switching of operation modes of the operator in response to a switching operation; and an operational-feeling switching mechanism that performs switching of operational feelings of the operator in response to the switching operation, along with the switching of the operation modes performed by the state switching mechanism.

Abstract: A rotary operator includes: a rotator including a movement path provided for an outer circumferential surface and inclined to a circumferential direction about a rotation axis, the rotator rotating about the axis; and a contact piece coming into contact with the rotator, and moving along the path in a direction along the axis in association with rotation of the rotator. Rotation of the rotator in a first rotation direction is restricted by the contact piece being at a first position when the rotator reaches a predetermined position. When rotating force applied to the rotator is reduced in a state where rotation of the rotator in the first rotation direction from the predetermined position is restricted, the contact piece returns to a second position to allow the rotation of the rotator in the first rotation direction from the predetermined position.

Abstract: An acoustic device includes a rotary operator and a base supporting the rotary operator so that the rotary operator is rotatable. The base includes a braking unit configured to be brought into contact with the rotary operator to cause a braking force to act on the rotary operator and an adjuster configured to adjust the braking force caused by the braking unit. The braking unit includes a plurality of contact members configured to be brought into contact with the rotary operator to cause the braking force to act on the rotary operator. The braking force acting on the rotary operator by the plurality of the contact members varies depending on an adjustment amount by the adjuster.

Abstract: Provided is an audio device that plays back music data. The audio device includes a first playback controller that performs, when a user performs an ON operation during playback of first music, application of a first effect to the first music, the first effect being set in association with the first music, and performs, when the user performs an OFF operation after the application of the first effect, application of a second effect to the first music or playback of a sampling sound, the second effect being different from the first effect.

Abstract: Provided is an audio device including: a detector configured to detect a rotational angle of a rotary operation element; a determination unit configured to determine, based on the rotational angle, whether a rotation direction of the rotary operation element is reversed; and an effect playback controller configured to play back an effect sound associated with an angle difference between the rotational angle based on when the rotation direction is reversed and a reference angle.
