Abstract: Methods and apparatus for coordinating audio data processing and network communication processing in a communication device by using time scaling for either inbound or outbound audio data processing, or both, in an communication device. In particular, time scaling of audio data is used to adapt timing for audio data processing to timing for modem processing, by dynamically adjusting a collection of audio samples to fit the container size required by the modem. Speech quality can be preserved while recovering and/or maintaining correct synchronizing between audio processing and communication processing circuits. In an example method, it is determined that a completion time for processing a first audio data frame falls outside a pre-determined timing window. Responsive to this determination, a subsequent audio data frame is time-scaled to control the completion time for processing the subsequent audio data frame.

Abstract: A digital audio signal processing system is disclosed that enable flexible coexistence of signals having different formats in the same hardware architecture. The system comprises at least one input, at least one first format transformer, and at least one digital audio signal processor. The at least one input is arranged to receive at least a first digital audio signal having a first format comprising a first symbol resolution and a first symbol distribution.

Abstract: The present invention relates to a method and a device for monitoring a system such as a cable. Pulses propagating in different directions are distinguished by measuring and sampling current and voltage at a location of the system, frequency transforming the obtained signals, and by extracting signals corresponding to pulses propagating in different directions as linear combinations of the frequency-transformed signals. Such a method is applicable, e.g. when monitoring occurrences of partial discharge on a 10 kV cable.
