Waves IR-1, IR-L, IR-360 manual Reverb Time

Reverb Time

The Reverb Time section includes these 4 parameters:

CONVOLUTION START: Range: 0 TO 1 second; Default: 0 seconds

The Convolution Start determines the starting point of the convolution process. It enables you to remove unwanted pre-delay at the beginning of an IR.

CONVOLUTION LENGTH: Range: 0 seconds to 6 seconds; Default: Full

This control sets the length of the process filter. By default it is set to Full, which means that the IR-Lwill convolve the input with the whole Impulse Response. However, if the IR is longer than 6 seconds then it will be cut to 6 seconds. This will be indicated in the IR Properties display. You can also set the Convolution length manually to be shorter than the RT60 Reverb time which will save some CPU. This will make the Impulse Response stop at some point down the slope, creating a “Gated” reverb sound. The default Full setting will only use the amount of CPU it needs for the loaded IR, so there is nothing to gain by manually setting it to 2 seconds for a 2 second IR.

RATIO: Range: .25 to 1.00; Default: 1.00

The Reverb Time Fader controls the Reverb Time Ratio. The resulting reverb time will be the original RT60 multiplied by the ratio.

RT60: RT60 (Reverb Time, 60dB) is defined as the time it takes the sound pressure level of a sound to drop by 60dB in gain once the source has been shut off. It is actually a slope factor. RT60 is a term that is commonly used in building construction and architecture to describe a room’s acoustic properties.

This field shows the reverb’s current RT60. It is the original RT60 multiplied by the Reverb Time Ratio. To determine what the original RT60 is, set the Ratio to 1.00. The original RT60 is calculated by analysis of the loaded IR.

The RT60 display is active only when RT60 may be computed on the IR. There is a minimum IR length (about 100 ms) for computing RT60 as well as for activating the reverb time ratio.

IR-360, IR-L, IR-1 specifications

Waves is a trusted name in the audio processing industry, and its range of plugins has consistently set the standard for professional audio production. Among its extensive lineup, the Waves IR-1, IR-L, and IR-360 are renowned for their advanced convolution reverb capabilities, delivering studio-quality reverb effects that enhance any sound environment.

The Waves IR-1 is a high-quality convolution reverb plugin that offers exceptional sound quality and versatility. Featuring a wide array of impulse responses derived from actual acoustic spaces, the IR-1 allows users to recreate the sound of various environments, from lush concert halls to intimate rooms. One of its standout features is the ability to manipulate the reverb tail, making it possible to fine-tune the duration and character of the effect. The IR-1 also includes controls for early reflections, damping, and pre-delay, enabling users to craft a reverb that perfectly complements their mix.

The Waves IR-L is a more streamlined version of the IR-1, designed for professionals who demand high-quality reverb but prefer a simplified interface. While it retains the core convolution technology and impulse response library of the IR-1, the IR-L focuses on ease of use, allowing for quick adjustments without sacrificing sound quality. One innovative feature is its “scalable” plugin structure, which lets users modify the plugin interface size based on their screen space. This makes IR-L ideal for both studio work and live sound applications.

Waves IR-360 is designed for immersive audio and 3D sound environments. By providing surround sound capabilities, it enables users to place sounds in a 360-degree space, making it ideal for film scoring and virtual reality audio. Like its predecessors, the IR-360 includes a rich selection of impulse responses, but it also integrates features tailored for spatial audio creation. This includes customizable parameters for azimuth and elevation, allowing precise control over sound placement in three-dimensional space. Additionally, the IR-360 supports various surround formats, making it versatile for multiple audio production contexts.

In summary, Waves IR-1, IR-L, and IR-360 offer powerful and innovative convolution reverb solutions, each designed with specific user needs in mind. With their advanced capabilities, extensive impulse response libraries, and user-friendly interfaces, these plugins cater to a wide range of audio production applications, setting new standards in reverb technology. Whether for music production, post-production, or immersive audio experiences, these tools are essential for achieving high-quality soundscapes.
