Abstract: A method for processing audio data includes determining a first common scalefactor value for representing quantized audio data in a frame. A second common scalefactor value is determined for representing the quantized audio data in the frame. A line equation common scalefactor value is determined from the first and second common scalefactor values.

Abstract: According to one embodiment of the present invention, a novel method and system are disclosed. In one embodiment, a first node records a first node local time of receiving a wirelessly transmitted packet, the first node local time recorded with a monotonically increasing clock of the first node. The first node wirelessly transmits the recorded local time to at least a second node. The second node records a second node local time of receiving the wirelessly transmitted packet and records the first node local time of receiving the wirelessly transmitted packet. The second node updates a second node timing model to synchronize with the first node, the updating based on the second node local time of receiving the wirelessly transmitted packet and the first node local time of receiving the wirelessly transmitted packet.

Abstract: According to one embodiment of the present invention, a novel method and system are disclosed. In one embodiment, an I/O device of a system receives or outputs a multimedia stream, the I/O device having a I/O clock and the system having a system clock. Samples from the multimedia stream are synchronized with the system clock.

Abstract: Data in a first channel of an audio signal may be compared to data in a second channel of the audio signal. Based on the comparison, the coding of the audio signal is adjusted to take into account any differences between the data distribution across the first and second channels. In one embodiment, an audio device determines the number of bits available to code the audio signal and adaptively redistributes the available bits between the first and second channels based on the comparison before coding the audio signal.

Abstract: An improved encoder of the type which generates long windows and short windows, and in which the short windows are grouped. The improvement lies in adaptively grouping the short windows, rather than in statically grouping them all together or all individually. In one embodiment, a new group is begun when a perceptual entropy value of a window crosses a predetermined threshold value with respect to its predecessor. In another embodiment, each group whose perceptual entropy value exceeds the threshold is its own group. The invention can be embodied as a digital audio encoder, for example.
