:: Correlation Meter

The Correlation Meter provides information about mutual phase-frequency relations between the signal of the left and right channel and allows us to spot any possible irregularities. These 'irregularities' may not have any significance in the case of stereo playback, but it should be remembered that the material we record can also be played as a mono signal (for example, on TV or on one of the radio stations which are broadcast or received in mono).

We can not emphasize enough how important it is that your final mix is as close as possible to your intended mix. Of course you will have to spend some time with the program to learn how to read the indications of the correlation meter. Correlation with percentaged values.

In this Settings dialogue all parameters of the correlation settings are to the user for individual attitude at the disposal.

:: AVERAGE in X : Here the time constant for the averaging of the correlation criterion is stopped. In the example shown above 6 values are averaged and spent then. With the next run the last value is then overwritten with the new. The adjustment possibilities are enough from 1 to 49. Consider thereby that high values are to be read off beautifully slowly, but fast changes of the correlation degree in the announcement are lost.

:: Interval in ms:
Here you can stop the time periods, in which the next in each case measured value is switched to the announcement.

Multi Mode Support. Switch between 4 Stereo Devices easily with the Keys (NUMBER PAD1 - 4). So you can analyze the input for Alesis ADAT, 8 Track Recording and any Multi Channel recordings...

NUMBER PAD1 = DispayDriver 1 & 2
NUMBER PAD2 = DispayDriver 3 & 4
NUMBER PAD3 = DispayDriver 5 & 6
NUMBER PAD4 = DispayDriver 7 & 8

:: The EQ Suggestion Module

The Eq suggestion provides equalizer settings on a 1/3 octave equalizer that will optimize the sound under "ideal studio conditions". Eq suggestion provides settings for the Equalizer faders to make the Sound (Input) linear.

The SA will allow the user to actually observe the holes or the overlevels(highs and lows) as a function of frequency. The user may easily copy the fader settings to an actual 1/3 EQ hardware unit.

Minor adjustments may be necessary as this process does not take into account any of the natural acoustics that are inherent and unique to each studio or listening area. If the user saves the results from Eq suggestion, then loads the file into the Graphic Equalizer 2.0, the data will set up the EQ automatically.

There will be a audibly noticeable difference between the original source and the revised signal due to the equalization process.

:: The Tap Delay Module

Tap Delay calculator- display for full, half and quarter Beats

:: Sound Check without a Band module

This section of the program offers the ability to make sample measurements of the frequency response of a performance area, without actually having the artists present. It may be utilized to set approximate EQ levels during the setup process. This will help reduce the typical last minute hassle of waiting for the musicians, performing a sound check, making required adjustments, redo the sound check

:: The Wave Player module

The Wave Player allows you the opportunity to load a pre-recorded Mp3/wav files and run an analysis of the data. All data contained in your sampling will be shown. Any changes made to the sampling rate will be automatically detected by the Spectrum Analyzer. The Locator is very practical when you work with big Wave files.

:: The Generator module

The built-in generator allows the correct calibration between Analyzer and the line-in signal. Generator leveling calibrated to 1/1000 of a dB.

:: Background module

You can load a frozen Spectrum as Background for better comparisons.Opportunity to select three various colors to make clear the difference amplitudes.

:: Musical Notes Detector

What are the frequencies of musical notes like G and G# in k-hertz?

FREQUENZ (in hertz)= 440 × 2^( (OCTAVE - 4) + ( TON - 10) / 12 )

What are the frequencies of musical notes like G and G# in k-hertz?

The answer to these questions is easily determined mathematically, but a bit of background should help the student use the mathematical relationships with confidence and understanding.

A piano keyboard is set up in octaves. Each octave has thirteen notes, with the thirteenth being the beginning of the next octave as well. Starting with A, an octave is A, A#, B, C, C#, D, D#, E, F, F#, G, G#, and again, A. The interval between each two successive notes is called a half-step. Therefore, there are 12 intervals of a half-step forming what is called an octave.

For starters, each octave up or down represents a doubling of frequency. For example, the A above middle C on the piano is set to the standard value of 440 Hz, so the A an octave above that has a frequency of 880 Hz.

Now, the particulars. The half-step is the smallest interval recognized in Western musical theory. Further, the frequencies of musical notes on a standard piano are now set according to a standard method, called 'equal temperament tuning'.

Side notes: Tuning systems cannot be treated in detail here. In short, there is a tradeoff in using equal temperament in that all harmonies are very slightly imperfect , but this method brings the overwhelming advantage over its predecessors that music may be written in any key with equal harmonic quality for each.

Bach largely popularized equal temperament and demonstrated its effectiveness with his series of pieces in all keys known as 'The Well-Tempered Clavier'. The equal-tempered tuning method's development is fascinating from a historical perspective (both scientifically and musically). The other methods of tuning and the whole nature of harmony, based on overtones of fundamental frequencies, with overtone frequencies determined as multiples of the fundamental frequencies, deserves further attention by the interested reader.

Back to our original story. In this equal temperament system of tuning, the frequencies of notes on a keyboard are related by a fairly simple mathematical relationship involving the number of keys (half-steps) between the notes.

To determine the relationship between the known frequency of a note and the unknown frequency (wished to be known) of another note, multiply the known frequency by 2 raised to the power (#ofhalf-steps/12). (#ofhalf-steps) is positive if one must move UP in frequency to arrive at the note with the unknown frequency, and negative if DOWN.

For example, if the A above middle C is set to 440 Hz (which is standard, usually called A440), the G just below it would have a frequency of 440 Hz * 2^(-2/12), or about 392 Hz. The G# in between them would have a frequency of 440 Hz * 2^(-1/12), or about 415.3 Hz. The G# an octave below middle C would be 13 half-steps below A440, giving it a frequency of 440 Hz * 2^(-13/12) = 207.65 Hz.

Note (pun intended) that the equation checks out with the previous assertion that octaves have factors of 2 differences in frequencies. Recall that there are twelve half-steps traversed in an octave: 2 ^ (12/12) is 2, while 2 ^ (-12/12) is 0.5.
