I-ADH

Automatic Dehissing
Automatically removes tape hiss and broadband background noise with minimal user intervention.

Auto Mode
Intelligently detects the noise content within the audio and applies appropriate noise reduction automatically.

Manual Mode
Provides direct control over noise detection settings for users who want to fine-tune restoration results.

Advanced Dehiss Algorithm
Uses a more sophisticated processing engine designed to reduce hiss while minimising common dehissing artefacts.

Broadband Noise Reduction
Removes continuous noise across the frequency spectrum, including tape hiss and similar background problems.

Reduced Processing Artefacts
Designed to minimise unwanted effects such as twittering, glugging, underwater sounds, and other dehisser side effects.

Automatic Noise Analysis
Identifies noise levels within the source material without requiring manual noise fingerprint creation.

Bias Control
Allows users to adjust how aggressively the algorithm identifies and removes noise in Auto mode.

Threshold Control
Provides manual adjustment of detected noise levels for precise control over restoration performance.

Low-Frequency Bias Control
Adjusts noise detection behaviour below 5kHz to accommodate different noise characteristics and recording conditions.

Adjustable Noise Attenuation
Lets users determine the maximum amount of noise reduction applied to the signal.

Frequency-Aware Noise Processing
Supports independent optimisation of low, mid, and high frequency noise reduction behaviour.

Ambience Preservation
Can be tuned to retain natural ambience, air, and spatial characteristics while reducing unwanted hiss.

Low-Frequency Noise Enhancement Control
Provides additional suppression for recordings with prominent low and mid-frequency noise components.

High-Frequency Hiss Optimisation
Can focus noise reduction on higher-frequency hiss while preserving low-frequency content.

Stereo MS Workflow Support
Can be used within Mid-Side processing workflows for more targeted stereo noise reduction.

Mid Channel Noise Reduction
Allows stronger processing of centre-channel noise while preserving stereo width and ambience.

Side Channel Noise Reduction
Supports heavier noise reduction in side information when noise is more apparent at the edges of the stereo image.

Simple Workflow
Designed to deliver effective hiss reduction with minimal setup and adjustment.

Fast Results
Unique Auto mode provides immediate noise reduction without complex configuration.

Restoration Optimised
Designed specifically for restoring noisy recordings while preserving the original material.

Tape Hiss Removal
Effectively reduces hiss commonly found on analogue tape recordings.

Audio Archive Restoration
Suitable for restoring historical recordings and archive material.

Broadcast Production Support
Can be used in broadcast workflows to improve the quality of noisy source material.

Film and Television Restoration
Suitable for post-production and soundtrack restoration applications.

CD and DVD Mastering Support
Helps prepare older or noisy recordings for modern distribution formats.

Music Remastering
Enhances legacy recordings by reducing hiss while preserving musical detail.

Podcast Production Support
Useful for improving spoken-word recordings affected by background hiss.

Theatre and Live Production Applications
Suitable for use in professional audio production environments.

Newsroom and Studio Workflows
Designed for professional speech and programme audio cleanup.

Cross-Platform Compatibility
Available for both macOS and Windows systems.

Professional Plug-in Formats
Supports AAX Native, AU, and VST3 plug-in formats for integration with major audio workstations.

iLok Authorisation
Supports both physical iLok devices and iLok Cloud licensing.

Single User License
Supplied as a single-user software licence with digital download delivery.
