摘要： A multimedia processing apparatus, method, and non-transitory tangible computer readable medium thereof are provided. The multimedia processing apparatus of the present invention includes an interface and a processing unit. The interface receives an audio stream continuously, wherein the audio stream is defined with a time line. The processing unit performs the following operations every a predetermined time interval: (a) deciding a first portion of the audio stream with reference to a time instant of the time line, (b) calculating an energy of the first portion of the audio stream, and (c) calculating a difference between the energy and a previous energy. The processing unit decides a plurality of second portions of the audio stream and decides a beat point for each of the second portions by selecting the time instant that corresponds to the maximum difference within the second portion.

摘要： A control method, suitable for an electronic device, includes following operations. A first connection is established based on a classic Bluetooth protocol or a Bluetooth Low Energy protocol from the electronic device to a first target device. A Bluetooth identifier of the first target device acquired in the first connection is recorded. The Bluetooth identifier of the first target device is shared. The Bluetooth identifier is utilized to establish a second connection based on the classic Bluetooth protocol or the Bluetooth Low Energy protocol to the first target device. The first connection and the second connection are established based on different protocols.

摘要： Methods and systems for media file management are provided. A music file is provided. The music file is analyzed to obtain a frequency spectrum corresponding to the music file, and at least one beat point on the time line is detected for the music file based on the frequency spectrum. Media data is generated for a plurality of media files in the electronic device based on the music file and a theme defining effects or transitions between the media files, wherein the sequence of the respective effects or transitions, and the corresponding media files which are selected for the respective effects or transitions are determined according to the at least one beat point of the music file.

摘要： Methods and systems for media file management are provided. A music file including music samples is provided. The music file is analyzed to calculate a gain for each music sample. At least one valley point is detected based on the gains of the respective music samples. A first and a second specific valley points are selected from the detected valley point, and respectively setting the first and second specific valley points as a start and an end of a music segmentation. Media data is generated for media files in the electronic device based on the music segmentation.
