Latest Patents

One of Tom Bäckström's latest patents is titled "Apparatus and method for noise shaping using subspace projections for low-rate coding of speech and audio." This invention provides an apparatus for encoding an audio input signal to obtain an encoded audio signal. The apparatus includes a transformation module that transforms the audio input signal from its original domain to a transform domain, resulting in a transformed audio signal. Additionally, it features an encoding module that quantizes the transformed audio signal and encodes it to produce the final encoded audio signal. The transformation module is designed to adjust the audio input signal based on predefined power values of quantization noise in the original domain.

Another significant patent is related to "Noise attenuation at a decoder." This patent describes various decoders and decoding methods. One such decoder includes a bitstream reader that provides a version of an input signal as a sequence of frames. Each frame is subdivided into multiple bins, each containing a sampled value. The decoder also features a context definer that establishes a context for the bin being processed, which includes at least one additional bin in a predetermined positional relationship. Furthermore, it incorporates a statistical relationship and information estimator to provide statistical relationships between the bin under process and the additional bin, along with a value estimator to estimate the value of the bin.
