This paper introduces a new method to perform signal processing using cells or atoms to synthesize variation in digital data stored in optical format. Interfacing small-scale biological or chemical systems with information stored on CD, DVD and related disc media has been termed molecular media. This is defined as micron or nanoscale interference and/or augmentation of optical data translation ...

The aim of this study was to evaluate the Differential-Rate Sound Processing (DRSP) strategy for speech perception by users of the Nucleus cochlear implant. The DRSP strategy uses both low and high rates of stimulation – applying a low rate of stimulation to apical, lower-frequency electrodes and a high rate of stimulation to basal, higher-frequency electrodes. Ten patients implanted with the N...

The authors examined the effects of a task-irrelevant sound on visual processing. Participants were presented with revolving clocks at or around central fixation and reported the hand position of a target clock at the time an exogenous cue (1 clock turning red) or an endogenous cue (a line pointing toward 1 of the clocks) was presented. A spatially irrelevant sound presented 100 ms before the c...

Slow envelope fluctuations in the range of 2-20 Hz provide important segmental cues for processing communication sounds. For a successful segmentation, a neural processor must capture envelope features associated with the rise and fall of signal energy, a process that is often challenged by the interference of background noise. This study investigated the neural representations of slowly varyin...

AudioSculpt is an application for the musical analysis and processing of sound files. The program allows very detailed study of a sound's spectrum, waveform, fundamental frequency and partial contents. Multiple algorithms provide automatic segmentation of sounds. All analyses can be edited, stored and used to guide processing within the application, such as spectral filtering, time-stretching a...

How does the sleeping brain process external stimuli, and in particular, up to which extent does the sleeping brain detect and process modifications in its sensory environment? In order to address this issue, we investigated brain reactivity to simple auditory stimulations during sleep in young healthy subjects. Electroencephalogram signal was acquired continuously during a whole night of sleep...

Since the introduction of the digital versatile disk (DVD) and the super audio CD (SACD), a revival of mul-tichannel audio has appeared in sound systems for consumer use today. It is, however, desirable to maintain compatibility with the existing two-channel stereo recordings and/or broadcasting. Therefore the conversion of two-channel stereo to the multichannel format has been studied extensiv...
