Notes, ornaments and intervals are examples of basic musical elements. Their representation as discrete-time digital audio plays a central role in software for music creation and design. Nevertheless, there is no systematic relation, in analytical terms, of these musical elements to the sonic samples. Such a compendium enables scientific experiments in precise and trustful ways, among education...

Music teacher’s reports suggest that the respiratory function and laryngeal control in wind instruments, stimulate muscular tension of the involved anatomical structure. However, the physiology and acoustics of the larynx during trumpet playing has seldom been studied. Therefore, the current paper describes the laryngeal articulation during trumpet performance with biomedical signals and audito...

Our goal is to process the soundtrack of a sports game (tennis) to understand the progress of the game and ultimately, infer its rules. The chair umpire’s speech is one of the most useful sources of information, and we focus on identifying the locations of this signal on the soundtrack. Although current techniques for audio segmentation can work well on this task when the acoustics of the train...

Electronic processing of audio signals is not new. Tone control by means of one or more analog filter stages is a well-known example from hi-fi technology the technology of the faithful reproduetion of speech and music. Another example is the improvement of audio quality by altering spatial perception with the aid of stereo effects and reverberation. The basic knowledge of acoustics and percept...

This article presents an approach that utilizes audio to discriminate the city of origin of consumerproduced videos – a task that is hard to imagine even for humans. Using a sub-set of the MediaEval Placing Task's Flickr video set, we conducted an experiment with a setup similar to a typical NIST speaker recognition evaluation run. Our assumption is that the audio within the same city might be ...

In the speech coding community a low-delay coding usually means that the coding delay should be less than 5 ms, e.g, 2 ms in ITU G.728 [2]. It is reasonable to adopt this rule also to low-delay wideband audio coding. An acoustic signal propagates in air less than one meter within 2 ms and therefore this low coding delay should not produce significant audible echo problems for example in high qu...

CONFERENCE REPORT The AES 45th International Conference, Applications of Time– Frequency Processing in Audio, continued the series—16th, 22nd, and 30th—of AES conferences organized by the AES Finnish Section. About 80 audio researchers were gathered at the Dipoli Congress Center in Espoo, which is located in the Helsinki capitol area. The venue has a unique architecture designed by Reima and Ra...

purpose: this study aimed to identify and introduce the most important evaluation and production criteria of audio books based on users’ point of view.method: in terms of methodology, this study was among the quantitative studies and done with descriptive survey. the research instrument was researcher-made questionnaire. population was all users of audiolib website that used from audio books mo...

Several audio reproduction systems can be used for creating these virtual sound fields: some are “lightweight”, attachedto-the-user systems, like the reproduction through headphones including the effect of HRTFs (head-related transfer functions), while some others are more expensive in terms of resources and materials. Among this last category are the systems based on multiple loudspeakers arra...
