Abstract: There are provided an electronic musical apparatus, a storage medium storing a recording/reproduction program, and a recording/reproduction method capable of outputting a musical sound phrase and a rhythm phrase after the input musical sound phrase is output. In a case where a recording button is operated, a looper starts to record musical sounds. In this case, the musical sounds (that is, a musical sound phrase) that are being recorded are output from a speaker. Thereafter, in a case where a loop reproduction button is operated, the recording is stopped, and loop reproduction of the recorded musical sound phrase and a rhythm phrase is started. Consequently, it is possible to output musical sounds in which the musical sound phrase and the rhythm phrase are loop-reproduced after the input musical sound phrase is output.

Abstract: A movable camera travels along an inspection path for optically inspecting an inspection surface of an object for defect detection. In planning the inspection path, a set of viewpoints on the inspection surface is generated. Each viewpoint is associated with a patch, which is a largest area of the inspection surface within a field of view (FOV) of the camera when the camera is located over the viewpoint for capturing an image of FOV. An effective region of the patch is advantageously predicted by a neural network according to a three-dimensional geometric characterization of the patch such that the predicted effective region is valid for defect detection based on the captured image. A valid area is one whose corresponding area on the captured image is not blurred and is neither underexposed nor overexposed. The inspection path is determined according to respective effective regions associated with the set of viewpoints.

Then, they are converted to time domain (TD) components with short echo effect and TD components with long echo effect. Selective TD components with short echo effect and long echo effect are combined to generate a convolved first channel output and a convolved second channel output.

Abstract: Each parameter is provided with increase/decrease switches and a slider. In a case where a user desires seamless rough control of the value of a target parameter, the user is to use the slider. In a case where the user desires easy control of the value of the parameter with the smallest unit of the resolution, the user is to use the increase/decrease switches.

Because the increase/decrease switch increases/decreases a parameter value by “1” at each manipulation, the range within which the parameter value can change by a single manipulation of the increase/decrease switch is “±1”.
