 DeBuZZ DeBuZZ is a high-end restoration tool that allows you to remove "Hum" and "Buzz" artefacts (Buzz tones with harmonics) quickly and automatically, using intelligent notch filters that remove unwanted harmonics without affecting the original program. A high-resolution real-time 'audio analysis' displays the frequency range between 20 and 130 Hz with single cycle resolution. The "Learn" function automatically analyzes the audio signal in real-time, defining the fundamental frequency of the disturbance and creating a harmonically related filter set. The filters are added sequentially, in accordance with the most dominant disturbance tones - guaranteeing the removal of the loudest disturbances as more filters are added. The filters created are adaptive and track any detectable shifts (eg. caused by wow and flutter, frequency drift) to .01 hertz. more info
SpectralDeHiss Expert SpectralDeHiss Expert is a de-noising tool which employs a sophisticated “fingerprinting” technique to analyze the audio signal in real-time – even if the noise floor is not separate from the program. Therefore, it is no longer necessary to look for a part of the recording where the noise is evident, as with many other plugins. SpectralDeHiss Expert can detect varying noise signals. Even highly colored noise/hiss is efficiently detected and removed without adversely affecting the original program or adding artifacts. With the optimized fingerprint algorithms that are available, difficult noise problems such as air conditioning noise, 35 mm camera noise, and outdoor ambiences can be safely reduced. more info
DeScratcher DeScratcher is used to interpolate large scratches up to 1000 samples in duration. Transient disturbances with a length of more then 30 samples demand different audio algorithms than short crackles. DeScratcher is optimized to carefully remove large scratches without damaging the audio program and is an extremely versatile plugin, incorporating 3 different detections modes. A specialized FingerPrint Mode can be used when working with regular, repetitive, impulse like disturbances, a task especially useful for forensic restoration or audio post-production. Furthermore, the Zero Detection mode offers the possibility to repair short muted regions automatically. more info
DeCrackler The DeCrackler allows you to remove small clicks, also known as crackles, which usually occur in short intervals (up to 1000/sec), are of short duration and have a low amplitude. The DeCrackler has been optimized to remove up to 8000 disturbances per second. The latest adaptive algorithms have been employed, significantly simplifying user operation. The DeCrackler can also be used in the reduction of analog distortion. The DeCrackler is therefore perfect for the restoration of vinyl and shellac recordings but can be used in a wide range of applications like soundtrack restoration or forensic work. more info
DeClipper DeClipper is a powerful tool used to recover peak signals lost as a result of recording over full-scale digital ("digital overs"). Not only is the dynamic range of the original recording reconstructed; DeClipper also eliminates the distortion components and the aliasing spectrum that might be created, as clipped program often has square wave characteristics. A level histogram and a de-clipping LED make it a snap to recognize clipped program, and a value field displays how much additional headroom would be required to restore the missing peaks. Using the "Level" fader you can create the headroom needed, and the algorithm will automatically calculate the shape that the waveform would have had, if no clipping had occurred. more info
RepairFilter RepairFilter combines an intuitive analytical tool with eight tracking notch filters and a high-pass/low-pass filter set. It can "surgically" remove steady state tones and other disturbances, while minimizing the effects on the rest of the audio program. The audio signal is displayed in a real-time spectrogram, and in ‘Auto’ mode, each notch filter will search for a steady-state tone and automatically set its center frequencies, bandwidth and attenuation (by using psycho-acoustic "masking threshold" algorithms). In ‘Cursor’ or ‘Edit’ mode, the operator has manual control over eachindividual filter parameter. RepairFilter simplifies the process of identifying and removing steady-state disturbances in old optical film sound recordings, mains hum and harmonics, video monitor line whistles, lighting buzz, musical instrument amplification buzz and idle tones from A/D -- all while maintaining the utmost in signal integrity. more info |
