The Advantages and Disadvantages of Past Technologies
Electronic “artificial“ reverbs offer the advantage of more control of individual reverb parameters, but their disadvantage is the lack of accuracy
reproducing real acoustic spaces. Conversely the attraction of Sampling or convolution based reverbs is the accurate reproduction of natural acoustic
spaces. Their chief drawback is the inability to control reverb parameters in the familiar and flexible fashion offered by traditional artificial reverbs.
IR-1 offers the best of both approaches without the compromises.
A Revolution of Control
IR-1 introduces the first Convolution based reverb that allows classic parameters to actually affect the convolution, not just “filter the result” in order to
produce parameter changes. This addresses the previous shortcoming of convolution based reverbs while maintaining controls familiar to artificial
electronic reverbs.
Decorrelation – While not a classic reverb control, de- correlation
allows greater control of the reverberation’s stereo spaciousness.
ER/Tail/Direct Independent Control – IR-1 analyzes the IR for the early
reflection/reverb tail (ER/Tail) boundary marker and allows the classic
control of gain and pre-delay for each portion.
Damping – Proportional to the reverb time, this control applies
innovative filtering methods to control the IR’s low, mid, and high
frequencies separately.
4-Band paragraphic EQ – Controls the reverb’s color by a Renaissance
based 4 band paragraphic EQ.
CPU Usage Control – Special Efficient-Stereo components requiring
less processing power; A "low CPU" mode utilizing intelligent
algorithms that require less CPU usage while preserving high sound
quality and definition.
Direct Convolution Length Control – This allows control over the length
of the actual real-time convolution. Therefore the CPU load can be
reduced if desired by using a shorter convolution length and a longer
RT 60.
96 kHz Support for high resolution
Reverb Time RT60 – Unlike existing products the IR-1 uses unique Impulse
Response (IR) manipulation techniques to allow shortening and lengthening
(times 4) of the Reverb Time while maintaining acoustic coherence and
preserving the natural envelope and frequency content.
Size – Controls the Room size and applies acoustic modeling methods on the
actual IR ER (Early Reflections) portion to make the space smaller or larger while
maintaining its signature.
Reverb Decay Envelope – A graph-based multiple breakpoint envelope allows
unlimited options for re-shaping the reverb’s decay behavior.
Density – Affects the space’s density and applies innovative modeling methods
by controlling the actual IR’s reflections, resonance, and inherent randomness to
make the space clearer or denser.
Reso – Analyzes the frequency response of the impulse response (IR) and derives
the room modes allowing acoustically based control of IR modal timbre.
IR-1 is for any DAW user who needs superior reverbs and ambiences. IR-1 is a convolution reverb which has flexible classic controls of
the key reverb parameters. Unlike other convolution reverbs only the IR-1 allows editing of all the traditional reverb parameters. IR-1 comes with an
extensive library of samples and presets that recreate the sonic environment of over 60 carefully sampled real acoustic spaces and over 60 samples
and presets created by classic hardware devices. The technology used in creating this library is based on the culmination of years of research by
leading acousticians with Waves and establishes new benchmarks for clarity and accuracy in a sampling reverb.
