An audio file is divided into frames in the time domain and each frame is compressed, according to a psycho-acoustic algorithm, into file in the frequency domain. Each frame is divided into sub-bands and each sub-band is further divided into split sub-bands. The spectral energy over each split sub-band is averaged for all frames. The resulting quantity for each split sub-band provides a parameter. The set of parameters can be compared to a corresponding set of parameters generated from a different audio file to determine whether the audio files are similar. In order to provide for the higher sensitivity of the auditory response, the comparison of individual split sub-bands of the lower order sub-bands can be performed. Selected constants can be used in the comparison process to improve further the sensitivity of the comparison. In the side-information generated by the psycho-acoustic compression, data related to the rhythm, i.e., related percussive effects, is present. The data known as attack flags can also be used as part of the audio frame comparison.

A method and apparatus for utilizing the benefits of encoded signal transmission and reception to enhance the performance of medical testing devices (100) adapted to evoke and measure biological response signals such as auditory evoked potentials (AEP), and the auditory brainstem response (ABR) signals in particular. Auditory stimuli, such as clicks, are presented to the ear of a human patient, in a predetermined encoded sequence, resulting in the generation of auditory responses and bio-electric response signals in the human patient. These response signals from the patient are acquired and observed, and are processed according to the predetermined encoded sequence in which the auditory stimuli were presented to the patient's ear in order to extract the desired auditory evoked potential signals or ABR signals.

A system for monitoring a brain wave response of a fetus in utero, comprises removably connecting an auditory transducer, including at least one biosensor electrode, producing pulsed auditory sounds to a mother's abdomen to detect brain wave activity in a fetus. The transducer is pulsed with one of rectangular waves and tone pips of a selected frequency to emit pulsed audible sounds at predetermined times. The at least one biosensor electrode, including connected amplifier, detects brain stem auditory responses (BAER) of the fetus. For each pulsed audible sound a series of voltage oscillations corresponding to BAER of the fetus are time-locked to the corresponding audible sound. BAER analog output is converted to BAER digital data. A computer-based QEEG (Quantitative EEG) system improves a signal to noise ratio of the BAER digital data using an adaptive optimum filtering algorithm and analyzes the BAER digital data relative to a reference database.
