Abstract:
1. A digital processing apparatus of audio signals, configured for treatment of subjects suffering from audio-phonatory disorders, comprising: an analog audiofrequency signal input configured to provide an audiofrequency input signal; an analog-digital encoder; an envelope detector; a digital limiter; a multiplier; a synthesizer; and a digital-to-analog converter, wherein the analog-digital encoder is configured to reflect the analog audiofrequency input signal by a first sequence of digital values; wherein the envelope detector is configured to establish, from the first sequence of digital values, a second sequence of digital values reflecting an envelope of the audiofrequency input signal; wherein the digital limiter is configured to establish a third sequence of limited digital values, from the second sequence of digital values; wherein the multiplier is configured to establish a sequence of modulated emission frequency values according to values of the third sequence of limited digital values; wherein the synthesiser is configured to provide a digital audio signal from the sequence of modulated emission frequency values; and wherein the digital-to-analog converter is configured to produce an analog output signal from the digital audio signal.
