![]() It did so with some success, though it was a destructive process and is vastly inferior to even the most rudimentary digital solutions. The SAE 5000 Impulse Noise Reduction system was a digital device based around a 68K Motorola CPU and had an algorithm that analysed the signal for fast-attack, short-duration, out-of-phase signal elements. ![]() You can read a white paper on the system Here. Even Marantz later had a go in the mid 90s with the SX-72 scratch suppressor, though by then vinyl sales were reaching their all time low as the compact disc took over.įirst impressions of the SC-1 are of a sleek, understated component with a minimalistic appearance, available in either a silver or black anodised chassis. A sparse front panel hosts buttons for Click Remove, Click Mon and Bypass, with a strength knob and status display. Around back are sturdy gold-plated RCA jacks for input and output, an RJ45 LAN connector and USB for the supplied wifi adapter. My only build quality gripe concerns the feet, the rubber protectors of which are o rings pressed into grooves in the foot. They can easily become dislodged and lost if the unit is relocated. I discovered quite by accident that 25 mm Sorbothane hemispheres are a perfect fit for the feet once the O rings are removed, providing a further level of isolation to the unit against external vibration. The unit is powered externally by a 12V, 2A power brick for which there is an associated connection and power switch. There’s also a Pair button for pairing the SC-1 with the SugarCube app for iOS and Android. Pressing the Pair button displays a four digit pair code on screen which is entered into the app, a process that needs to be completed only once. #Best setting for clickrepair denoise lf code# There’s a great deal more going on inside. The SC-1 incorporates 24-bit, 192kHz analogue to digital and digital to analogue converters. The SugarCube runs on the Debian 8 (Jessie) linux environment and runs a proprietary algorithm which, instead of identifying frequencies or bands of audio with problems as would a primitive noise reduction solution, looks for events in the time domain and removes them by interpolating the slope of the preceding audio. Music has repeating patterns and musical sounds typically have an attack and decay while clicks and pops are isolated impulses that stand out in duration and strength. The SugarCube algorithm hunts for candidates to repair and applies a set of pre-defined rules to ensure no music is removed. Some sounds however, the click of a stick on a drum rim for example, can appear roughly symmetrical in attack and decay and thus be identified as a click or pop. The software rules are updated in such cases to avoid false detections. #Best setting for clickrepair denoise lf software# ![]() As with any noise reduction solution, the more complex the source material the greater the likelihood of the system detecting and falsely removing musical information. However the SugarCube algorithm operates similarly to how an engineer would manually remove noise from a recording, and thus achieves greater accuracy. The SC-1 can be connected in various ways, and should be able to integrate into most systems. If you have an external phono stage, connect its output to the input of the SugarCube, and the output of the SugarCube to your amplifier. ![]() This method also applies to those using turntables with inbuilt RIAA preamplifiers. If your amplifier has a tape loop function, the SugarCube can be connected there. ![]() It should be noted that if this method is to be used, your amplifier’s tape loop function must be a true tape loop that is to say, it must have the ability to play back its tape source while sending a second input to its recording jacks. #Best setting for clickrepair denoise lf code#.#Best setting for clickrepair denoise lf software#. ![]()
