Zusammenfassung: | According to an embodiment, an audio processing apparatus is disclosed. The apparatus includes a microphone configured to receive an acoustic input signal and to generate a microphone signal, a pre-amplifier configured to receive and amplify the microphone signal and to generate an amplified microphone signal; a digitizer configured to receive and digitize the amplified microphone signal and to generate a digitized input audio signal i(t), a processor configured to receive the digitized input signal i(t) and to determine and/ or predict spectral information from the input audio signal i(t) and/or from a demodulated signal x(t); and a signal processor configured to receive the input signal i(t) and the spectral information for modifying the input signal i(t) to generate a composite audio signal c(t). |
