EB2-1 A Broadcast Film Leader with Audio Channel, Frequency, and Synchronism Test Properties—Luiz Fernando Kruszielski, Globo TV Network - Rio de Janeiro, Brazil; Rodrigo Meirelles, Globo TV Network - Rio de Janeiro, Brazil
Universal film leaders, commonly known as “countdowns,” have been an important tool to synch audio and video. In a broadcast production, the material goes through several stages where audio and video are edited and processed, and time is a very precious resource. Also, it is important to minimize possible errors in the production chain. We propose a film leader format that, in a single 10 second clip, would be possible to do a preliminary check on aspects such as surround and stereo channel identification, relative channel level and frequency response, as well as synchronism. The proposed film leader has been tested and integrated in a Brazilian Television Network with very good results.

EB2-2 Live vs. Edited Studio Recordings: What Do We Prefer?—Amandine Pras, Paris Conservatoire (CNSMDP) - Paris, France; Stetson University - DeLand, FL, USA
This pilot study examines a common belief in written classical music that a live recording conveys a more expressive musical performance than a technically flawless studio production. Two tonmeister students of the Paris Conservatoire recorded a six-dance baroque suite and a four-movement romantic sonata in concert and in studio sessions with the same microphone techniques and in the same venue for both conditions. Twenty listeners completed an online survey to rate three versions of the dances and movements, i.e., the concert performance, the firstt studio take, and the edited version. Results show that listeners preferred the edited versions (44%) more often than the firstt studio takes (29%) and the concert performances (27%).

EB2-3 Rondo360: Dysonics’ Spatial Audio Post-Production Toolkit for 360 Media—Robert Dalton, Dysonics - San Francisco, CA, USA; Jimmy Tobin, Dysonics - San Francisco, CA, USA; CCRMA - Stanford, CA, USA; David Grunzweig, Dysonics - San Francisco, CA, USA
Rondo360 is Dysonics’ toolkit for spatial audio post-production, supporting multiple workflows including multichannel, Ambisonics, and Dysonics’ own native 360 Motion-Tracked Binaural (MTB) format. Rondo360 works with all input formats—live or prerecorded—from traditional or sound field microphones, and exports to a wide array of formats depending on desired content distribution. Rondo360 integrates seamlessly with all DAWs by adding a final layer onto the creator’s existing workflow, and it comes bundled with a suite of custom mastering tools (Mixer, Compressor, Limiter, and Reverb) that work on multichannel sound field content. With support for RondoMotion, Dysonics' wireless head-tracking device, creators can monitor their 360 mixes in real-time. Rondo360 also provides an intuitive audio/video sync and export functionality along with live broadcasting support.

EB2-5 Mixing Hip-Hop with Distortion—Paul "Willie Green" Womack, Willie Green Music - Brooklyn, NY, USA
The grit and grime of Hip-Hop doesn't have to be metaphorical. With the vast array of saturation tools available, distortion is no longer just something to remove from recordings; and the huge and aggressive sounds in Hip-Hop music can benefit specifically. From subtly warming drums and keyboards to mangling vocals and samples, this brief will demonstrate techniques for creatively distorting urban music. Exploring tape emulation, parallel vocal distortion, drum crushing, and more, I will investigate how a bit of dirt can drastically affect a mix.

EB2-6 Smart Audio Is the Way Forward for Live Broadcast Production—Peter Poers, Junger Audio GmbH - Berlin, Germany
Today’s broadcast facilities are facing ever-increasing demands on their resources as they strive to keep up with consumers who expect more content on more devices both where and when they want it. To attract and retain viewers, consistent, stable, and coherent audio is a vital requirement. One aspect that is particularly important to pay attention to is speech intelligibility. This is most critical and difficult in a live broadcast situation. The Smart Audio concept is to utilizing real time processing algorithms that are both intelligent and adaptive. Devices need to be fully interoperable with others in the broadcast environment and need to seamlessly integrate with both playout automation systems and logging and monitoring processes. The Engineering Brief will present some dedicated and proofed algorithms and practical use cases for Smart Audio

EB2-7 Towards Improving Overview and Metering through Visualization and Dynamic Query Filters for User Interfaces Implementing the Stage Metaphor for Music Mixing—Steven Gelineck, Aalborg University Copenhagen - Copenhagen, Denmark; Anders Kirk Uhrenholt, Copenhagen University - Copenhagen, Denmark
This paper deals with challenges involved with implementing the stage metaphor control scheme for mixing music. Recent studies suggest that the stage metaphor outperforms the traditional channel-strip metaphor in several different ways. However, the implementation of the stage metaphor poses issues including clutter, lack of overview and monitoring of levels, and EQ. Drawing upon suggestions in recent studies, the paper describes the implementation of a stage metaphor prototype incorporating several features for dealing with these issues, including level and EQ monitoring using brightness, shape, and size. Moreover we explore the potential of using Dynamic Query filtering for localizing channels with certain properties of interest. Finally, an explorative user evaluation compares different variations of the prototype, leading to a discussion of the importance of each feature.
