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.
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
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.
