The concept of augmented reality audio characterizes techniques where a real sound environment is extended with virtual auditory environments and communications scenarios. A framework is introduced for mobile augmented reality audio (MARA) based on a specific headset configuration where binaural microphone elements are integrated into stereo earphones. When microphone signals are routed directl...

Streaming audio has become a popular form of media on the Internet. As wireless personal area network architectures (e.g. Bluetooth) are now targeted to support multimedia traffic, streaming audio over these technologies will give rise to interesting applications. But, the variable nature of the wireless medium will not lend itself easily to supporting audio streaming. In this paper we focus on...

This extended abstract describes the pattern discovery submission to MIREX 2014 of an algorithm that uses music segmentation (or music structure analysis) techniques and a refined greedy method in order to identify the repetitive musical patterns of a given music piece, either represented symbolically or with an actual audio file. We obtain a harmonic representation of the input and compute the...

Recent studies have shown that the audio-visual synchrony is recalibrated after adaptation to a constant timing difference between auditory and visual signals (i.e. temporal recalibration). Here we investigated whether the temporal recalibration occurs for audio-visual speech using an off-line adaptation method. After 3 minutes of lag observation, the audio-visual synchrony is recalibrated towa...

Point-count surveys are widely used to infer avian presence and estimate species richness. Advancements in bioacoustic technology enable automated surveys that can supplement human-based pointcount surveys with expanded temporal and spatial coverage. We surveyed birds in 13 Sierra Nevada and Cascade Range (CA, USA) montane meadows from May to August 2006 using 8 point-count surveys and automate...

Noise Filtering in audio signals has always been a challenge since the noise is spread across a large bandwidth and overlaps the spectral range of the audio signal being recovered. In audio systems all these can be kept below the audible level but ambient noise may not be avoided even if the audio system is designed according to the best practices. So, there have been several audio filtering te...

State of the art audio coders exploit the redundancy in audio signals by shaping their quantization noise below the signal's masking curve, which is a signal-dependent threshold of audibility. This framework can be extended to the context of data hiding, where the data play the role of noise. To minimize audio distortion the data power should be closely adapted to the time-varying masking curve...
