1 Sampling Digital Reverberator

2 Shape your acoustic environm The Sony Sampling Digital Reverberator offers audio professionals a new approach to sound processing. The is a technologically advanced digital effects processor that recreates the real ambience reverberation of concert halls, theaters and soundstages with an unparalleled depth, presence and richness. Unlike conventional processors, the achieves this breathtaking naturalism by using highly advanced processing that allows audio signals to be combined with sampled data taken from real reverberant sound spaces. Sony engineers have painstakingly collected sample data from some of the world s most highly regarded halls, studios, and other acoustic environments plus a classic analog plate reverb. Reverberation has long been the most popular effects used in music, film and television soundtrack production. To date, 2

3 ent with real reverberation. digital reverbs have relied on artificial synthesizer technology to create reverb effects. The bridges this gap between artificial and real to redefine the possibilities of natural sounding reverb creation in the studio. The accepts input signals with 24-bit precision and at sampling rates up to 96 khz for uncompromised audio fidelity. This superb audio resolution is coupled with multi-channel surround sound capabilities, extending the applications for the to cover a wide range of modern production tasks, from high-end music recording to project studios, film, television and video post production facilities. The enclosed demonstration CD provides a brief introduction to the astonishingly lifelike world that is made possible with the. Sampling Digital Reverberator 3

4 Real-world reverb To elevate the state of the art in reverberation, it is necessary to capture the unique sound of a real acoustic space. That is where Sony engineers found the concert halls, churches and other venues to sample and re-create with the. The sampling itself was no mere mechanical process. Rather it was a full-fledged recording project that required a host of creative decisions familiar to audio professionals. The sampling system required loudspeakers to emit the test signal and microphones arrayed in the position corresponding to each mode offered by the.

Not content with quick measurements, Sony engineers sampled each acoustic space across a wide range of conditions. The can offer a variety of programs and settings for each acoustic space.

6 Seven standard acoustic environments Grosser Musikvereinssaal, Vienna, Austria The provides seven standard presets including the ambience of halls (two types), recording studio, church (two types), and plate reverberation (two types). Reverberation can be reproduced precisely as captured. Or the ambience can even be delivered together. Adjustments such as reverb time and pre-delay are possible for detailed sound creation. Also available: the great concert venues of Europe An important option, Sony DASK-S701 software contains reverb data from European concert halls. These are gems of architectural acoustics -- well known to classical music listeners worldwide. Concert halls like the Musikvereinssaal and the Concertgebouw are now available for your projects! And Sony engineers will continue to travel the globe, expanding our software library. St. Vincente de Cardona, Cardona, Spain Sony Music Entertainment (Japan) Inc. Shinanomachi Studio Optional Sampling Reverb Data DASK-S701 European Halls & Churches This CD-ROM provides impressive reverb programs sampled at seven treasured halls and churches in Europe: the Concertgebouw (two hall types), Musikvereinssaal, Konzerthaus, Jesus-Chiristus- Kirche, Westerkerk, and St. Vincente. 6

7 More natural surround sound In addition to the stereo reverb modes, Sony has developed the to support reverb processing in multichannel sound production. The emergence of formats such as high-capacity DVD-Video have widely expanded the importance of multi-channel sound. The addresses these new opportunities by offering a multi-channel output, extending the processor s appeal across audio for video, television and film post-production applications. The (with the optional DABK-S703 DSP Board) provides up to four-channel output (mono in). Fivechannel input and output modes are also possible by using three or four connected units. The optional DASK-S701 software includes reverberation data actually sampled using a five-channel microphone array, allowing five-channel surround sound effects to be delivered with a dramatically real, deep soundstage. 7

8 Real-time DSP For years, the holy grail of Digital Signal Processing has been Real Impulse Response convoluted in real time. Unfortunately, the required processing power simply has not been available. That is why most digital reverberation systems have only simulated acoustic spaces: Artificial Impulse Response using approximation of early reflections and reverberation. Until now. A new Sony DSP developed expressly for the has 1,000 times the processing power of previous designs. Sony s DSP convolutes an amazing 256 k separate points. This enables far more comprehensive, far more convincing reverb. Not just the early reflections, but the complex reverberant tails are faithfully captured in Sony s Real Impulse Response. The does a far better job in the realistic, detailed reproduction of each acoustic environment. In fact, the is not simply a reverberation effect processor, but a real ambience emulator. Conventional Digital Reverberator Amplitude Real impulse response (e.g. Sampler) Amplitude Approximation of impulse response (e.g. Synthesizer) Whole impulse response (256 k point convolution) Time Pickup of early reflections Adding of articial reverberation Time Rich and natual reverberation Very large processing power (until now 1000 DSPs or more) carried out by only 11 Sony DSPs Artificial reverberation 2 Small processing power (1 DSP) 8

9 96 khz Sampling for higher level of sound quality As the music and movie industries move from 48 khz to higher sampling rates, the can follow suit. The optional DABK-S703 DSP Board upgrades the for the 96 khz sampling frequency. In this way, the is future-compatible with Super Audio CD and DVD- Audio and other emerging audio formats. Whisper-quiet signal-to-noise ratio As well as delivering astonishingly lifelike natural-sounding reverb effects, the also provides whisperquiet signal to noise performance. This has been achieved by taking multiple samples for each of the programs. Post processing of the sample data involves an averaging technique that allows the signal to noise to be dramatically improved; the net effect is a cleaner, more dynamic subjective sound quality. This approach also provides special benefits when recording the reverberant signature of noisy devices such as analog plates. The accurately captures the unique characteristic of these devices, with unwanted noise dramatically reduced to produce a reverb effect that is cleaner than the original plate. High quality A/D and D/A conversion The is equipped with highquality digital interfaces to ensure the integrity of digital audio signals. To extend its versatility further, the reverb processor has optional analog con - verters DABK-S701 (A/D Converter Board) and DABK-S702 (D/A Converter Board). These converter boards incorporate discrete-transistor amplification, critical for maintaining the integrity of analog signals. The result is uncompromising A/D D/A performance to match the superlative reverberation. 9
