AES Academy 2020

Presented in Spanish: Music mixing is sometimes seen more as a technical hurdle at the end of a project rather than the creative process it is. In this session, producer and engineer Juan de Dios Martín will share his approach to ITB mixing, focusing on ideas and strategies for both audio engineers and musicians that work on their own productions.

(Mezclar música se puede ver a veces más como una dificultad técnica al final de un proyecto que como el proceso creativo que es. En esta sesión, el productor e ingeniero Juan de Dios Martín compartirá su enfoque sobre la mezcla ITB, centrándose en ideas y estrategias tanto para ingenieros como para músicos que trabajan en sus propias producciones.)

As parametric EQ is an effective equalizer for studio applications, adding dynamic control to parametric bands expands its spectral shaping palette. We show the architecture of dynamic parametric EQ as well as specific monitor and control features that allow detailed sculpting of audio components, featuring the processor Quartet DynPEQ.

The Distributed Mode Loudspeaker – A New Class of Radiator for Sound Reinforcement

Distributed Mode Loudspeakers (DMLs) utilize bending wave modal physics to propagate wide directivity, predominantly diffuse acoustic energy into a given space. Unlike traditional loudspeaker systems, the net effect is a single, large drive unit that radiates audio over almost eight octaves in a very wide and diffuse manner. In this talk, Tectonic Audio Labs VP of Engineering Tim Whitwell will explain how a DML works, what the radiaton from a DML looks like, and the benefits this brings to sound reinforcement applications.

In “The Secret Life of Low Frequencies”, Bruce Black explores what can occur in the all-important low frequency realm, and why it happens. Using more than a decade’s worth of data collected from the acoustic analyses of rooms ranging from large world class mix stages down to small home studios converted from spare bedrooms, he shares the surprising discoveries and obscure answers to sometimes baffling questions. The low frequency region, below 300 Hz. or so, is where the bulk of our perception of sonic quality takes place. It is also an unforgiving territory where there are many complications and pitfalls that can damage the sound in the critical acoustic spaces where we do our work - our mix rooms, control rooms, studios and the like. In designing a room’s acoustics, it’s easy to stumble and fail. Some of what he will present goes against the common wisdom, and some may be controversial. But he will give you plenty to think about.

A moving microphone technique will be introduced and evaluated for measurement of spatial average in small rooms. Consistency of measurements will be assessed including measurements made by multiple experimenters. Accuracy of this method will be investigated in comparison with spatial average calculated from a large number of static microphone positions. A survey of measurement techniques will be presented and compared to the same spatial average.

Presented in Mandarin. Condenser microphones are a staple in any recording studio. This lecture intends to look at them through various physical aspects to explain where their performance and characteristics derive from. Small diaphragm versus large diaphragm, center terminated capsule versus edge terminated capsule, polar pattern aggregation, pad, noise, and dynamic range are topics to be explored in this...

Presented in Mandarin. Video content with surround or immersive sound tends to rely heavily on large playback systems to create an accurate sound image. HRTF creates a possibility in which listeners with stereo headphones can enjoy surround or immersive content. This lecture intends to give a brief intro to HRTF, as well as to explore various potential problems in applying HRTF to surround content.
