Disposable audio processor for use with implanted hearing devices
TLDR
A disposable audio processor for use with implanted hearing devices is provided and may include a finger tab for manipulating the device.Abstract:
The echo canceller is designed to be placed between a hands-free acoustical interface and a communications network. It comprises a plurality of processing paths connected in parallel and each allocated to one of a plurality of adjacent sub-bands taken from the spectrum band of the output signal. Each path comprises an analysis filter receiving the echo-containing signal for transmission after correction, a second analysis filter receiving the incoming signal coming from the network, and feeding an adaptive filter that supplies an estimated echo in the respective sub-band to the subtractive input of the subtracter and a synthesis filter. The adaptive filters in at least some of the sub-bands implement a QR decomposition RLS algorithm on the incoming signal, using the fast version thereof, with or without recursive order.read more

Methods for improving high frequency reconstruction
TL;DR: In this article, a detection mechanism on the encoder side is used to assess what parts of the spectrum will not be correctly reproduced by the HFR method in the decoder.
Patent
Efficient and scalable parametric stereo coding for low bitrate audio coding applications
TL;DR: In this article, a method for decoding an encoded power spectral envelope of a stereo or multichannel signal having two channels was proposed, which is based on a balance parameter for each frequency band indicating in each band a ratio of power in the two channels, a level parameter representing a total power of the two channel per frequency band, comprising the step of converting the balance and power parameters into power values of the first and second channels.
