    摘要： A computerized method for filtering a digital audio file to generate an output audio file that induces optimal health and cognitive ability in a listener of a playback of the output audio file is described herein. The method includes the steps of identifying a plurality of target frequencies that span within an octave, identifying a plurality of mid-point frequencies that are situated at mid-points between any two adjacent target frequencies, applying a peaking filter to the digital audio file centered around the plurality of mid-point frequencies to produce highest frequency attenuation at the plurality of mid-point frequencies, and generating the output audio file.

    摘要： Disclosed is a method, apparatus and non-transitory computer readable storage medium, which is configured to examine an input audio signal to determine an estimated pitch period associated with a detection criterion, encode the filtered audio signal to generate a compressed audio bit stream, decode the compressed audio bit stream to generate a decoded audio signal and adaptively filtering the decoded audio signal to produce an output audio signal, wherein adaptively filtering the decoded audio signal comprises filtering each of a plurality of segments of the decoded audio signal in a manner that is dependent upon the estimated pitch period associated therewith, and wherein a pitch-based post-filter operates to shape noise components located between harmonics of the input audio signal.

    摘要： Multi-user portable electronic devices for improving reading ability and/or comprehension for a plurality of subjects are provided. The multi-user portable electronic devices may include a pitch shifter circuit configured to generate frequency altered auditory speech feedback (FAF) signals corresponding to respective auditory speech signals received from respective active microphones, and to transmit the respective FAF signals to the plurality of subjects while one or more of the plurality of subjects are respectively reading aloud, to improve the plurality of subjects' reading ability and/or comprehension. The multi-user portable electronic devices may also include a switch configured to activate the microphones selectively, serially. Related methods and systems are also described.
