Abstract: Techniques are disclosed for providing distributed audio playback and recording functionality according to certain embodiments. In such embodiments one or more client audio devices can be connected to a server computing device via a network connection, thereby providing distributed audio playback and recording functionality to the server computing device. For example, audio tracks may be recorded at the server computing device based on audio signals collected from one or more remotely-located smartphones. In certain embodiments a transmission control protocol (TCP) network connection is used to transmit audio signals between the server computing device and the one or more remotely located client audio devices, thereby eliminating the need to provide physical cable connections between the devices. Distributing audio data over a network connection also reduces compatibility issues between audio software used by the server computing device and audio hardware provided by the one or more client audio devices.

Abstract: The present invention discloses an apparatus and method for determining a padding length and an image processing method and apparatus. The apparatus for determining the padding length of an image in an image filtering direction may include an aliasing effect function obtaining unit for obtaining an aliasing effect function of a frequency domain filter for the image, wherein the aliasing effect function is a function representing spatial domain variation of an aliasing effect caused by a frequency domain filtering processing; and a padding length determination unit for determining the padding length for the image in the image filtering direction based on the aliasing effect function. Thereby the aliasing effect can be substantially eliminated and the amount of calculation may be reduced.
