Figure 1 9 An interpolated Estimate with Bin Controls At this point you now have a green Interpolation with blue Bin Controls attached Select the Write Estimate command to save the Estimate as a file that will be used by the Broadband DeNoise processor 1 2 2 2 Where to take an Estimate Once the source sound file is opened into a Panel of a Project the first step is to identify a suitable location from which to take the Estimate Since the denoising algorithm depends on a constant amplitude and spectrum in the noise floor try to listen and locate a time region with uniform noise As to duration optimum results are obtained when the Estimate is taken from a section of pure noise between about 0 3 and 0 5 seconds in length with a worst case minimum of 100 milliseconds If a region of pure or clean noise noise uncontaminated with program is unavailable as is often the case with tightly edited material then choose a region with minimal program The resulting Estimate will require manual adjustment as discussed below If an Estimate must be taken in presence of signal it is advisable to avoid sections of spectrally complex or non harmonic material as it makes manual adjustment more time consuming It is usually necessary to derive a separate Estimate for each cut or take If these are contained in a consolidated sound file and the spectrum of the noise varies for each cut then the consolidated file should be denoised in s

5. 2 4 3 Sharpness As mentioned earlier in the introduction the denoising process works much like a multiband downward expander As signal level in a particular band drops the process reduces the gain in that band even further using an internal attenuation curve The Sharpness parameter sets the slope of this curve Higher values cause quicker attenuation as instantaneous energy falls off from the Threshold value resulting in a response similar to that of a noise gate Sharpness Curves Threshold Attenuation dE o m Figure 1 11 Sharpness Curves If Sharpness is set too low there may be no reasonable amount of noise reduction possible despite what the other parameters are set to Generally this parameter should be set as high as possible without audible ill effects on the program A value of 1 0 is recommended for common tape hiss problems while a value of about 1 2 has been found useful for standard 78 RPM phonograph recordings If the sharpness is too high you may hear the noise floor become less uniform producing a rapid modulation 1 2 4 4 Bandwidth Denoising with each Bin adjusted separately produces an unnatural sounding result In Broadband DeNoise individual Bins share information for more pleasing subjective result Bandwidth governs this process Higher values produce more intra Bin sharing of gain changes Subjectively a higher value will in general create a more natural sounding result but with a risk of no

7. DeNoise 1 2 1 Introduction Broadband noise whether white pink or brown in spectrum is one of the most common forms of audio degradation Noise can be introduced from any of a number of sources including the modulation and asperity noise inherent in analog tape recording and Johnson or thermal noise from microphones preamps and other analog signal processing equipment Broadband DeNoise is a single ended broadband noise reducer that unlike less refined examples can suppress or eliminate broadband noise with little or no audible artifacts even at extreme settings Page 9 To suppress such noises in your program it is necessary to analyze the noise spectrum and adapt the denoising algorithm to the characteristics of the material Broadband DeNoise operates by means of analysis and resynthesis though it can be thought of as 2048 bandpass filters each followed by a below threshold expander This is somewhat analogous to the classic analog Dolby and dbx multi band double ended noise reduction systems of yore An FFT or Fast Fourier Transform analysis is performed on a user specified sample of noise from the material to be processed The average amplitude of noise in each of 2048 individual frequency bands or bins is determined The result of this analysis is a Noise Estimate which is used to set the average threshold of the noise reduction The Estimate sets aggregate threshold for the expansion During processing the source ma
