Overview

Picture 1: The sound analyzer
Picture 1: The sound analyzer

The Soundanalyzer makes it possible that the light control adapts to the music to time and the level automatically. This almost can draw without operator for one party business be used very well.

This module offers a detailed spectrum analysis in which the 24 detail steps can be manipulated and assigned to a channel directly. Next to the beat module another possibility is here, offered beat to extract from an external music source.

Description

So that the sound analyzer can accomplish his tasks, the window permanently must remain opened. The sound analyzer lets himself over the menu « Window » Menu item « Sound analyzer » call as well as directly about the symbol.

It is necessary at the sound Analyzer to understand three concepts which overlap and agree on the complete module generally:

  • The source and its manipulation
  • The beat generation
  • The Sound2Light function and its restrictions


 Important Hint The source in BLUE , the beats in RED und Sound2Light in GREEN.


Sources

Till now, the two Winamp sources (VbVis or AVS) exclusively can be selected for the sound Analyzer (also see program configuration, rider tools).

Both are in the program configuration and the former is activated by specification. Thanks to the possibility, with Winamp also linein:// (at the need of also the same sound card = line out) and line of the sound card be of use possible, every other player for which to play by additional audio drivers or a simple interconnecting cable between the sound source. It that both VbVis and AVS distribute the changes at the Winamp equalizer has to be taken care, however the volume of Winamp, itself influence on the version not has. Check in the choice of linein:// the input levels of her sound card/the Windows mixer.

As soon as you have set up a proper source, you, joists permanently changing in BLUES, should be able to see.

Beat

The beat is symbolized by the red small box which should flash regularly. All (two) attitudes for the beat also are represented by limits in RED. The version of the beat is always active. Merely wrong threshold values can cause that the field remains dark for the beat. If a control of stock exchange securities or sequences is planned, then the hooklet must correspondingly be activated for beat triggered (music controlled) at the modules cue list module or chaser module.

Sound2Light

If the hooklet is put in the corresponding box here, the S2L control is activated. One, however, doesn't immediately see an effect at the very first use since a channel (of a device) must be assigned to one of the 24 spectrum joists at least. To be able to adjust this, it requires, however, a bank besides the existence of at least a device (see Devices),

The attitudes being stored in this one. So more configurations can be stored per project. Only the channels of the spectrum joists, however, become stored and not the values of the other regulators in the sound Analyzer. If a channel is assigned, the joist GREEN changes color exactly like the switching threshold if this is active. The values of the levels are, converted and distributed directly on DMX values of 0-255 with what classic clavilux effects with 24 detail steps 1:1 nachbauen can.

Controls

One can manipulate the source directly and therefore influence both beat and S2L with the element spectrum increase. The value can be varied between 0 and 255 in which no change is carried out in the middle at about 128. This attitude can a little finer over the button « Edit channel settings » being adjusted.

Beat settings

The beat can be found out from a source on two different ways. With the first one over the Spectrum-Analyzer (short Analyzer) and with the second over the VU meter ( short VU ). The Analyzer can be configured with the red rectangle (in the upper area). Whenever one of the spectrum joists rises into this rectangle, a beat is recognized. The rectangle is adjusted by the 4 regulators around the spectrum indication.

The VU meter method is a simplified method of the level analysis [1]. The red marking into the joist below the spectrum indication puts a threshold value there which can be changed with the mouse. A beat is recognized if the VU advertisement exceeds the threshold value. « AutoGain » can here with a click actively/deactivated (-) and shows the multiplier found out automatically.

Sound2Light settings

If one of the 24 spectrum joists is assigned to one or several channels (click on one of the joists), then this gets GREEN and you can store in a bank. The S2L function can be activated/deactivated about the corresponding hooklet now.

There are another four attitudes which concern ONLY the S2L:

  • Switch threshold at X%:
  • Ignore trigger level (see button Edit channel settings)
  • Set to X% when above threshold:
  • VU-meter

The switching threshold is the lower value which must be exceeded so that a S2L version is carried out. The values above the switching value are NOT distributed newly on all 255 values but merely all values put on 0 below the threshold. The threshold is therefore e.g. only values of 26-255 therefore arrive at 10% at the DMX device (> 25. 5). This global attitude can with a hooklet under « Edit channel settings » be lifted for some spectra again (checking box « Ignore trigger level »).

One still would like (that is only 0, or value on X) can so to receive a binary version in addition, under « Set to X% when above threshold » a DMX value 'X' which is always submitted to the version as soon as the threshold value was exceeded being adjusted. This attitude doesn't have any effect as soon as « Set to X% when above threshold » you deactivated.

This « VU meter » is the easiest to understand if one sees it. A spectrum joist therefore should for test purposes, instead of device, the dimmer channels are assigned to one by 4-8 devices. The choice is radio button « All similar » the behavior is same at all lamps, put. The choice is radio buton , though « VU meter » the rash splits up (since possible for 2. 11), on all 4-8 joists so. Watch ideal in the graphic stage view (at positioning of Generic dimmers besides each other. )

Module commands

  • Modul: Sound Analyzer
  • Meaning from device/function and channel
Device/Function Description Channel Description
Sound2Light The further orders (channel) only are applied to the Sound2Light function. On/Off The function can the T flags under use and be turned off one.
Activate With the command the Sound2Light function is activated.
Deactivate With the command the Sound2Light function is deactivated.
Bank With the function bank the appropriate bank from this can drop down be selected in the sound analyzer. Bank name The bank names laid out correspondingly stand drop down in the sound Analyzer under channel from this.

Meaning of the Flags:

Flag Meaning Description
T Toggle mode The Flag »Toggle mode« result in the function's being set by the first call and being reset by the second call.
O Used specified value The Flag »Used specified value« result in the being assigned to the appropriate channel of the value in the openings' value. This value isn't DMX value 0 to 255 but a per cent value 0. 000 to 100. 000%
A Ask for value The Flag »Ask for value« result in the opening at call of the order of an input window in which the per cent value can be entered.
I Ignore value 0 The Flag »Ignore value 0« result in the being ignored of a value of zero. Do you need at some orders to ensure a correct function.
