摘要： Reduction in reproduction quality is suppressed in an imaging device that images a sound and a moving image. A frame rate converter converts a frame rate of a frame captured outside a predetermined period among a plurality of frames captured at a predetermined frame rate to a low frame rate lower than the predetermined frame rate. A duplication unit duplicates an original sound signal recorded over the predetermined period to generate a plurality of duplicated sound signals each of which is identical to the original sound signal. The audio signal processing unit performs different signal processing on each of the plurality of duplicated sound signals.

摘要： A mobile terminal is disclosed. A mobile terminal according to the present invention connects an output stage of a receiver to an input stage of a speaker amp and compensates for a distortion of a signal input to a microphone, where the signal exceeds Acoustic Overload Point (AOP) of the microphone, by using an external audio signal received by the receiver in a recording mode, thereby generating distortion-free recording contents.

摘要： A vehicle infotainment system that adds background sounds to an outgoing call on a mobile device. The infotainment system comprises: i) a database of selectable augmenting audio signals; and ii) audio processing circuitry configured to receive at a first input an uplink signal from the infotainment system and receive at a second input a selected augmenting audio signal. The audio processing circuitry adapts a spectrum of the first selected augmenting audio signal to prevent the selected augmenting audio signal from masking the uplink signal and combines the adapted selected augmenting audio signal and the uplink signal to produce an augmented uplink signal at an output.

摘要： A method and associated software application (“app”) for synchronizing audio across a plurality of mobile devices such as smart phones. In some implementations, the method syncs all the smart phones together allowing users to use the headsets on the smart phones instead of having to use speakers. In some implementations, the application syncs the audio by first downloading the audio onto the smart phones and then syncing it across the smart phones by using in conjunction, the clock on the smart phone, the clock on a server and/or the time obtained from GPS satellites.
