1st Latin American Conference 1st Latin American Conference
Multi-Channel Audio
August 19-21, 2007
Panamericano Hotel & Resort - Buenos Aires, Argentina

These three days in Buenos Aires are a must-go event for every person related to the fascinating Pro Audio world. The main topic, Multi-Channel Audio, takes into consideration the tremendous growth of the surround sound in the industry of Entertainment, as much as in everyday life.

This Conference aims to gather all professionals and students that have direct or indirect contact with the various fields of Multi-Channel Audio. The event's main goal is to facilitate the interchange of opinions and experiences among the participants, adding up to the presence (for the very first time in Latin America) of numerous Audio personalities with the highest level of recognition throughout the world. Registration and the Technical Program are now available.

AES Conference on DSP for Loudspeakers 32nd AES International Conference
DSP for Loudspeakers
September 21-23, 2007
Pharmakon - Hillerød, Denmark

Digital signal processing (DSP) offers loudspeaker system designers a very powerful set of tools. It may be as simple as a delay line, which hardly needs DSP anyway. Or it may be a precise and detailed filtering with just the desired magnitude and phase characteristics. Such filtering may be used to construct a single very accurate loudspeaker, or used for room correction, or it may be used to create beam-steering arrays or even wavefield synthesis. In addition to filtering, digital signal processing may be used for distortion compensation, or for enhancing the subjective performance by means of nonlinear processing. On the analysis side, DSP can be used to monitor in real time the state of the loudspeaker and model important driver parameters such as voice coil temperature. Through the last couple of decades, AES members have been in the forefront of this research.

Meanwhile, the maturity and price/performance ratio of essential system components such as processors, software development tools, AD/DA converters, and power amplifiers have reached a point where it makes commercial sense for a large part of the audio industry to apply loudspeaker-specific DSP in their products. Indeed, there are already classes of products completely depending on it.

This international conference aims to present the state of the art within the rich and still emerging field of loudspeaker-specific DSP and create an inspiring and synergetic meeting between professionals in the fields of electroacoustics, psychoacoustics, room acoustics, transducer physics, and DSP. Registration and the Preliminary Program are available online.

AESSC 78 rpm Calibration Disc Set
AESSC 78 rpm Calibration Disc Set
AES Standards provides a rare opportunity to calibrate playback equipment for 78 rpm coarse-groove records. Recognizing an international need for calibration tools, the AES Standards Working Group on Transfer Technologies (SC-03-02) initiated a project to calibration playback equipment for coarse-groove 78 rpm records. The result is now available as a boxed set of two identical 12-inch vinyl discs, catalogue number AES-S001-064. The two discs allow one to be used as a day-to-day working tool while the other may be stored as a master reference.
