Bayview Pro Audio - Intonator

Quality Tools For Quality Engineering
Tonal integrity is a must when dealing with delicate human vocals. The Intonator preserves the artist's personal touch by allowing vibrato, initial intonation and correction limited to individual notes. Utmost care has been taken in the software development to ensure that all fine adjustments applied to the incoming signal are being processed in a subtle, yet highly effective manner!

Transparency
Based on TC's world-renowned DARC™3 chip technology (incorporating 96kHz internal processing and true 24 bit resolution), the Intonator provides you with an ultra-transparent signal path. It features fully integrated AES/EBU, S/PDIF, Tos-link and ADAT digital I/O’s, and is 96kHz, 88.2kHz, 48kHz and 44.1kHz compatible on both digital and analog I/O's.

Coherence
Apart from the clear advantages of reducing the time spent on doing vocal re-takes, the Intonator also brings back coherence into the performance. Instead of cutting and pasting bits and phrases, with the loss of coherence as an obvious result, you now have a professional tool for processing and correcting your vocals in real-time.

Two Signal Setups
The Intonator also makes you capable of configuring the signal path in two different ways. In Normal mode the ADIOS (Analog Dual I/O's) configuration enables you to make simultaneous recordings of processed and unprocessed vocals, making comparisons a breeze (see fig. A). Digital signals, from your digital multitrack recorder for instance, can be configured the same way. In Dual mode you have the option of pitch-correcting the signal in one channel while using the dynamics, De-esser and LoCut, on the signal in the other channel (see fig. B).

Being On Top
You can choose to correct a single note simply by using the unique "Do-not-process-anything-but-this-note" function achieved via an internal custom scale feature, or type in your personal scale. A Pitch window allows you to specify when a note will be considered out of tune, whereas the Amount control limits the level of Pitch correction added to the audio.

The Audio-to-MIDI conversion allows you to keep track of the incoming pitch history and/or correction history, giving you the advantages of being on top of things throughout the entire recording session.

The Intonator features full MIDI automation making time based pitch shifting a simple operation. Use your keyboard for real-time manual pitch correction simply by hitting the notes to be processed.

Dithering
The use of dithering is very important when interfacing digitally between audio equipment. When resolution is changed from higher to lower, dithering is necessary to minimize distortion. In the Intonator you have the user friendly TPDF Dithering. The Output resolution of the Intonator is 24 bit, when the receiver of the Intonator signal has a lower resolution, Output Dither must be applied to equal the resolution of the receiver.

Premium Converters
When converting from analog to digital or vice versa, you should always try to use the full dynamic range of your converters. Even though the converters in the Intonator are 24 bit, analog gain may be applied before the AD's and after the DA's to make full use of them. The analog signal-path is balanced and can carry professional levels.

Applications
With the Intonator, you can establish a completely digital signal-path for vocal editing and correction. When tracking, the unit’s fine A to D converters may be utilized to get high quality digital signals directly to Multitrack, ADAT, ProTools etc.

Audio-to-MIDI
With a simple setup you can monitor and edit your vocals externally. Just track the incoming pitch history to your sequencer, add the necessary correction and play back the pitch correction to the Intonator

Keyboard
The keyboard gives you instant access to changing the Root note of the current scale or the notes allowed to be corrected. Simultaneously the keyboard also indicates the incoming note, making it possible to recognize the note about to be processed.

Display
The Display shows you the current Root note and Scale. While processing you can see both the incoming signal and the amount of correction added to the source, creating a visual confirmation of the process taking place.

Window, Attack and Amount
These three knobs allow you to individualize the processing in detail. The Window knob determines how close to a particular note the source should be in order to be corrected. The Attack knob conducts the response-time before the correction sets in. This will help preserve the artist's personal touch by e.g. allowing vibrato. The Amount knob sets the amount of correction added to the signal.

Manual Pitch
Use the Manual Pitch control to add pitch correction by hand. The wheel can also be remote controlled by your keyboard modulation wheel or even provide in-sync changes when locked to a sequencer.

The De-esser uses a relative threshold technique. This means that the actual threshold is always set according to the average level of the source signal. Consequently, the De-esser always adapts to the incoming signal and maintains the same threshold to the average level regardless of the Input signal.

Adaptive LoCut
The Adaptive LoCut is a pitch controlled LoCut Filter. Instead of cutting off frequencies under a predetermined value, the Adaptive LoCut filter controls the cut off frequencies dynamically in accordance with the incoming signal. This ensures a perfect LoCut that never removes too much low end.
