Abstract:
A device includes a decoder that includes an extractor, a predictor, a selector, and a switch. The extractor is configured to extract a first plurality of parameters from a received input signal. The input signal corresponds to an encoded audio signal. The predictor is configured to perform blind bandwidth extension by generating a second plurality of parameters independent of high band information in the input signal. The second plurality of parameters corresponds to a high band portion of the encoded audio signal. The selector is configured to select a particular mode from multiple high band modes including a first mode using the first plurality of parameters and a second mode using the second plurality of parameters. The switch is configured to output the first plurality of parameters or the second plurality of parameters based on the selected particular mode.
