Abstract: A signal processor comprising: a modelling block, configured to receive a frequency-domain-input-signal, a fundamental-frequency-signal representative of a fundamental frequency of the frequency-domain-input-signal; and configured to provide a pitch-model-signal based on a periodic function, the pitch-model-signal spanning a plurality of discrete frequency bins, each discrete frequency bin having a respective discrete frequency bin index, wherein within each discrete frequency bin the pitch-model-signal is defined by: the periodic function; the fundamental frequency; the frequency-domain-input-signal; and the respective discrete frequency bin index. The signal processor further comprises a manipulation block, configured to provide an output-signal based on the frequency-domain-input-signal and the pitch-model-signal.

Abstract: A device including a processor and a memory is disclosed. The memory includes programming instructions which when executed by the processor perform an operation. The operation includes detecting relative position of two earphones when connected to the device, determining if a binaural signal processing mode is appropriate based on the detected relative position and switching to the binaural signal processing mode. If it is determined that the binaural signal processing mode is not appropriate, switching to monaural processing mode.

Abstract: A signal processor comprising: a signal-manipulation-block configured to: receive a cepstrum-input-signal, wherein the cepstrum-input-signal is in the cepstrum domain and comprises a plurality of bins; receive a pitch-bin-identifier that is indicative of a pitch-bin in the cepstrum-input-signal; and generate a cepstrum-output-signal based on the cepstrum-input-signal by: scaling the pitch-bin relative to one or more of the other bins of the cepstrum-input-signal; or determining an output-pitch-bin-value based on the pitch-bin, and setting one or more of the other bins of the cepstrum-input-signal to a predefined value; or determining an output-other-bin-value based on one or more of the other bins of the cepstrum-input-signal, and setting the pitch-bin to a predefined value.
