Algorithmix Plug In and Software Bundles

Precise emulation of legendary analog equalizers, extended by progressive, new models: standard / vintage / modern / experimental. A sonic paradise for every recording and mixing engineer.   A few years ago we did not even think about spending our time to develop perhaps the 157th parametric equalizer on the market. Why one more? Is it possible to be noticed among all the other already established products? 
It was you, our customers using our LinearPhase PEQ Red and Orange who asked Algorithmix to develop a classical recording/mixing equalizer but with its unparalleled purity and transparency. The biggest problem we had in the beginning was the equalizer style, so we closely analyzed many of them. To satisfy our customers as much as possible, we decided to implement not only one, but an entire collection of traditional (minimal-phase) equalizers. Most of them emulate analog archetypes; some are based on new ideas. 
We hope you enjoy the dozen shades of Blue and find that favorite sound you previously could get only from very expensive outboard gear. 
Shelf and Cut Filter Library 
In Classic PEQ Blue, not only are various bell filters used but also different kinds of shelving filters. Nine of the serial equalizers use a new shelving filter generation characterized by cut-off frequency defined in the middle of the transition part. We found these filter definitions more intuitive than the classical ‘– 3 dB below maximum’. The old definition is only used in the Classic Asymmetrical type to conform to its original predecessor. All 2nd order shelving filters have a Q adjustment to emulate vintage characteristics with their specific bumps at higher slopes. Also, the parallel equalizers are equipped with respective shelving filters shapes being typical for the old parallel PEQs and interacting with other bands as did their analog predecessors. 
Every complex PEQ is equipped with cut filters. In Classic PEQ Blue, each of the 12 equalizers can assign 1st and 2nd order cut filters. The 2nd order filters have a Q adjustment to create so-called resonant filters characteristics and very steep brickwall filters after cascading more of them (Butterworth, Bessel, Elliptic). 
The best of the analog and digital world Classic PEQ Blue is a creative equalizing tool combining the best of both the analog and digital worlds. We modeled the most legendary analog equalizers including two parallel ones and added a few experimental characteristics only possible in digital domain. To avoid bell filter asymmetry at high frequencies, typical for many digital equalizers, we have applied reference-quality upsampling techniques, automatically switchable if the sampling frequency of the input signal is 44.1 or 48 kHz. By using proprietary filter algorithms, we have achieved a huge dynamic range, as well as extremely low noise and distortion level and thus unparalleled sound purity--impossible with any analog circuitry. The whole equalizer collection works with sample rates up to 384 kHz and therefore is perfectly suitable for DSD post-processing. Several instances can be opened simultaneously. Complete setups can be easily exchanged between them. The true frequency response display is zoomable and in the DirectX version the whole PlugIn can be enlarged to the full screen.

Every mastering engineer knows that equalization of final complex mixes or orchestral recordings with stereo microphones is very critical and limited. 
Any correction of a single instrument or vocal part influences other instruments and can negatively change their sound characteristics. This is because all classic equalizers change the phase of the fundamentals and their harmonics and the phase shift is frequency dependent. 
The LinearPhase PEQ Orange does not shift the phase, it only boosts or cuts the amplitude in a given frequency range. Consequently you can apply much more boost without changing the sound character of your recording. Due to our proprietary low-noise filter design in the time domain, the distortions (THD+N) are extremely low ensuring crystal clear, neutral, and uncolored sound. 
The LinearPhase PEQ Orange DirectX/VST PlugIn is unique in the world of audio components. Almost all parametric equalizers being used are implemented with filters that accomplish phase shift, e.g. the original signal is remixed with its phase-shifted version. Because the amount of the phase shift is frequency dependent some cancellation or amplification at certain desired frequencies takes place. It works, but with a major disadvantage - the different signal components are spread all over time, so that the time relationship between harmonics in the processed signal is heavily affected. The result is that a nice sharp bass drum becomes slurred and muddy and vocal tracks become strident or brittle. Algorithmix is proud to offer you a true remedy against difficult equalizing tasks, the LinearPhase PEQ Orange PlugIn, a linear-phase equalizer which can be handled exactly like its classic predecessors, but cannot be "heard". The LinearPhase PEQ Orange successfully copes with sonic problems that cannot be solved with any classical equalizer without side effects. You can boost lower frequency regions by even 10dB without mud or slush and with no loss of transients at all. You can remove the sibilance from a vocal with a sharp notch without affecting the whole mix like occurs when using analog or IIR-based digital EQ. 
LinearPhase PEQ Orange better preserve the time relationships of harmonics in the original waveform. This translates to smoother top end, sweeter and bigger midrange, and a clearer more distinct bottom end as compared with phase-shifted EQ. The resultant sound seems less processed, more like it occurred naturally in the air in front of the microphone. The mixes become clear and transparent, the instruments more defined and realistic. The LinearPhase PEQ Orange works in the time domain. It sounds more analytical than its brother, the LinearPhase PEQ Red, and therefore is specially recommended for difficult mastering and re-mastering tasks on dense mixes. It performs flawlessly with up to 384 kHz sampling frequency and allows extended frequency setup up to 80 kHz, thus being ideally applicable for high-resolution DSD post-processing, including its ultrasonic region.

Experts say that most of digital equalizers do not sound like their analog predecessors, especially when working with low sampling frequencies: 44.1 or 48kHz. Spectrum modifications in the high-frequency region sound as improperly balanced. The reason is so called frequency warping which makes the bells asymmetric and high shelving and high-cut filters much steeper as theoretically set up. To make the LinearPhase PEQ Red analog sounding, special corrections have been applied to the original digital filters making them look exactly like their analog references. 
The LinearPhase PEQ Red features the Continuous Slope Filter™ technology, proprietary to Algorithmix® and the only one of its kind, worldwide. Unusual flexible shelving and cut filters allow adjustment of any slope in the range from 0 to 24dB/octave. 
The LinearPhase PEQ Red better preserves the time relationships of harmonics in the original waveform.

The LinearPhase PEQ Red works in the frequency domain. It sounds a bit softer than his brother, LinearPhase PEQ Orange. It perfectly performs with up to 384kHz and allows extended frequency setup up to 80kHz. These features make it perfectly applicable for high-resolution DSD post-processing, inclusive the ultrasonic region.

Algorithmix 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.

Clicks and crackles are inseparable companions of old vinyl and 78 rpm records. Before re-mastering to CD they have to be removed and the remaining gaps have to be reconstructed properly.
The Algorithmix ScratchFree™ Pro DirectX Plug-In copes with any kind of transient noises, efficaciously preserving the audio quality of the original signal.
The ScratchFree™ Pro DirectX Plug-In effectively removes clicks and crackles from old vinyl and shellac records and cleans up audio recordings tainted by switching noise, static discharge, digital cross-talk, or thyristor buzz.
Unlike other systems, the ScratchFree™ Pro DirectX Plug-In works virtually without artifacts when using correct settings for all parameters. It includes an excellent de-crackling algorithm preserving timbre, ambience, and low-level details in the original signal.
Since the CPU requirement for the ScratchFree™ Pro DirectX Plug-In is very low, you can change and optimize all parameters while listening to the audio in real-time.
The de-scratching algorithm consists of two main parts: the de-clicking module and the de-crackling module. While the de-clicking module is used to remove severe clicks from old shellac and vinyl records or switching noise originating from improper setups of digital audio equipment, the de-crackling module removes any remaining small clicks and crackles.
The signal scope helps you to find ideal settings for the DeCrackler. The advanced parameters Width, Smooth, and DePlop are useful to minimize the appearance of artifacts. The unique Differ feature allows intuitive parameter settings. You can switch between the output signal and the input/output difference, i.e., the part of input signal taken out by the de-scratching algorithm. Normally, this differential signal should not contain any audible parts of the original audio material that you want to preserve.
ScratchFree™ Pro provides pre-defined application profiles (Type). They preset the internal parameters and external advanced parameters to help you in typical restoration situations: digital spikes, shellac and vinyl. In addition to its main application, the removal of clicks and crackles, the ScratchFree™ Pro DirectX Plug-In effectively diminishes any kind of distortion caused by signal overload (Clipping).

Never before has audio repair has been that easy and effective!
Algorithmix easyNOVA™ removes unwanted audio incidents and replaces the vacancy with re-synthesized audio, intelligently created from surrounding context without affecting original audio in an audible manner.
The whole process is high-resolution and linear-phase, thus extremely transparent.
Try to remove a feedback whistle occurring during a gentle violin ensemble part, without noticeably leaving traces of the edit with all the normal tools and techniques on your disposal. It ain’t easy! With easyNOVA™, it takes a few seconds and the result is jaw dropping.
What is it? Denoising techniques work well for stationary or quasi-stationary broadband noise. Short clicks coming from old records or switching noise can be successfully removed and replaced by declicker plug-in. However, neither a denoiser nor a declicker can successfully cope with longer complex audio disturbances, especially if they overlap material we want to recover. This fact has motivated us to develop a special tool, reNOVAtor™ and later its brother, easyNOVA™, especially optimized for time-effective workflow.
easyNOVA™ is intended to rescue high-resolution live or location recordings from extraneous sounds and unwanted audio disturbances. Often, from the performance point of view, brilliant live recordings can not be accepted for CD release, because of disturbing noises like coughs, squeaky chairs, feedback squeals, horn of a passing truck, a bell from the neighboring tower, or ring tones from a cellular phone. Such disturbances are especially critical if they occur in quiet passages when recording classical music. Similarly, location recordings film, broadcast or TV often include annoying incidents which disqualify them to be used as originally intended. In these cases any kind of traditional equalization or editing methods is very time consuming and causes audible discontinuities in desired signal and ambience. Often after hours of hard work even the best post-pro engineer will capitulate.
How does it work? easyNOVA™ helps when all other editing tricks and processing methods fail. It allows localization, identification and very precise removal of unwanted audio events mostly without audibly affecting the audio material we want to keep. The removed sound is replaced by a signal re-synthesized from the surrounding material. Unlike time editing methods, easyNOVA™ does not make deep gaps in the sound track when eradicating a disturbing sound event. Rather, it’s an exactly tailored hole in the spectral representation of the processed signal that can be removed and replaced. 
easyNOVA™ or reNOVAtor™? easyNOVA™ is optimized for very time-effective workflow and therefore equipped with well prepared preset-like controls. It’s ideal for post-pro broadcast, TV and film engineers working under extreme time pressure. When you deal with extremely tenacious disturbances or you just want to broaden your abilities and increase performance in cleaning audio material do upgrade to reNOVAtor™ that features extended manual parameter setup and some additional advanced functions.
