NoiseFree Pro automatically removes or reduces any kind of constant background noise like hiss, surface noise, hum, or camera sound. Due to the Algorithmix proprietary, psycho-acoustically optimized noise reduction algorithm, NoiseFree Pro efficaciously preserves timbre, ambience, and low-level details of the original signal, as well as highly reduces the appearance of artifacts. On one hand, it can be used for high-resolution re-mastering tasks. On the other hand, it is a real weapon in cleaning up critical speech recordings for forensic purposes.
One quite common problem in the daily business of an audio engineer is a noisy signal. The standard methods of noise extraction by means of filters do not work if spectral components of noise overlap the desired signal. In such situations the only solution is to use sophisticated signal processing algorithms to suppress unwanted noise in a much more intelligent way.
The NoiseFree Pro DirectX PlugIn effectively removes broadband noise from pre-recorded audio material. It has been designed to perfectly cover a wide range of applications: from the high-quality de-noising of valuable music treasures, to cleaning location recordings for film from environmental noise, even the treatment of critical forensic material recorded at a very poor signal-to-noise ratio and/or in reverberate environment. Typical tasks for the NoiseFree Pro include removal of tape-hiss, surface noise of old records and wax cylinders, broadcast noise, microphone and preamp noise, as well as enhancement of conversations and interviews that lack intelligibility.
Unlike other systems, the NoiseFree Pro DirectX PlugIn works virtually without artifacts when using the correct settings for all parameters.
The de-noising process can work based on either the built-in white noise profile or a recorded noise profile. The unique Learn algorithm allows recording a noise sample from virtually any part of audio material, even if there is no noise-only part available. A sophisticated 5-band Noise Profile EQ is provided for modifying the shape of noise profiles and smoothing them for optimal performance. The parameters Ambience recovery and Decorrelation allow fine tuning the NoiseFree Pro to differentiate between noise and sharp signal transients. The Chase function--mainly designed for speech de-noising--automatically detects any fluctuations in the background noise and adjusts the Noise Profile according to these changes.
NoiseFree Pro works impeccably with sampling rates up to 192 kHz. Thus it is perfectly suitable for hi-res DSD post-production. Since the CPU requirement for the NoiseFree Pro DirectX PlugIn is quite low, you can change and optimize all parameters while listening to the audio material in real-time.
Features:
- performs with up to 384 kHz sampling frequency, thus perfectly suitable for DSD post-production
- based on a proprietary, psycho-acoustically optimized noise reduction algorithm preserving--to a large degree--timbre, ambience and low-level details of the original signal
- automatically removes or reduces any kind of constant background noise like hiss, hum, or camera sound
- removes residual and surface noise from old 78 rpm and vinyl records remaining after de-clicking and de-crackling process
- very effectively helps in cleaning up poor recorded dialogs or telephone cuts to be restored for forensic purposes
- allows recording of a noise profile in two different ways:
(1) for the de-noising of high-quality recordings from noise-only part of the recording,
(2) for time-saving task from any part of the input material
- provides a sophisticated noise profile modifier
- noise profiles can be also created from flat noise using noise print modifier
- automatic background noise chasing function for adaptive real-time de-noising
- pre-defined processing profiles simplify de-noising tasks in typical situations
- clickless real-time parameter adjustment during playback possible
- expert parameters for minimizing the appearance of artifacts
- virtually no artifacts when using correct settings for all parameters
- spectrum analyzer for real-time tracking of the de-noising process
- unique difference function for real-time audio monitoring the noise being removed
- short learning curve; good results within minutes with only two sliders
- extremely high internal calculation precision (double floating point - 80 bits)
- moderate CPU load, thus suitable for real-time multi-channel operation
- automatic latency compensation with Sequoia and Samplitude
Applications:
- removing tape hiss and electronic noise from preamps and audio processors
- de-noising after de-clicking and de-crackling of old records
- re-mastering old recordings to CD, SACD, or DVD
- cleaning up live recording from environmental noise
- eliminating camera and air-condition noise from film and video soundtracks
- reducing noise in recordings coming from optical soundtracks
- cleaning up noisy dialogs and telephone cuts for forensic purposes
- reducing noise from AM, short-wave, and FM radio, as well as TV sound
- real-time operation with a turntable, tape deck, or radio receiver
- archiving and restoration of historic audio material
- removing tape hiss and electronic noise from preamps and audio processor
