The quality of audio in IP telephony is significantly influenced by the impact of packet loss rate, burstiness and distribution on a specific audio compression technique. In this paper, we propose a novel statistical-based on-line audio quality assessment framework, Audio Genome, that can deduce the audio quality of an on-going Internet audio for many different codecs under any network loss con...

The feasibility of and the necessity for an objective estimate of the psycho physiological perception of sound after compression are discussed. Some possible methods are studied. The preferable method is the consonance method. The essential principles of this method are offered algorithm of human auditory system and musical theory. The method and measurements results are discussed. Key-Words:re...

This paper addresses the role of expectation for product Sound Quality evaluation. In two different experiments it was shown that expectations (induced by priming tasks or as mood) systematically influenced how sounds are perceived. Moreover, temporary influences such as mood interacted with more stable individual differences such as noise sensitivity. These findings suggest that sound quality ...

the quality of the communication between teachers and students and ultimately, of classroom education itself, is closely linked to the acoustic quality of the auditorium. this acoustic quality can be characterized based on the reverberation time (rt), speech transmission index (sti) and the sound insulation. in this context, an acoustic study was conducted in an auditorium located in the higher...

Modern hand prostheses are capable of mimicking finger or wrist movements using electrical motors, gear mechanisms and control elements. The drive systems and the transmission mechanisms emit machinery noises which can activate or enforce a foreign body sensation by users. Transfer-path-analysis is originally developed to investigate the individual vehicle noise paths. It is a useful tool for t...

Synthesizers have become commonplace in music production due to their ability create a diverse and unique timbre. However, many users find it difficult control synthesizer the complexity of relationship between synthesis parameters output sound. As such, sound matching task focuses on estimation that recreate target as closely possible within capabilities synthesizer. In this paper, we introduc...

Automatic audio classification usually considers sounds as music, speech, silence or noise, but works about the noise class are rare. Audio features are generally specific to speech or music signals. In this paper, we present a new audio feature sets that lead to the definition of four classes: colored, pseudo-periodic, impulsive and sinusoids within noises. This classification relies on works ...

The main advances of the R&D Sample Orchestrator project are presented, aiming at the development of innovative functions for the manipulation of sound samples. These features rely on studies on sound description, i.e. the formalization of relevant data structures for characterizing the sounds’ content and organization. This work was applied to automatic sound indexing and to the development of...

In this paper we present a set of spectral domain audio transformation technologies and some existing and proposed applications of these technologies in video games. The technologies include real-time voice transformation and tempo/pitch transformation for music. Voice Transformation is mainly used to create new character's voices modifying existing recorded material but also for transforming t...
