SACCARA is an ambience syntheser. It utilizes Sphinx Modular Media technology. The purpose of this software is to produce all sort of ambient noise like wind and water. Until version 1.0 this software will be free for noncommercial use.

Saccara SA-01 consists of four sections.

Modulators

This section has 3 LFO's (Low Frequency Oscillator). The shape combobox selects a waveform. You can choose between

• Sine
• Triangle
• Pulse
• Sawtooth
• Random

The frequency is adjustable between 0.005 and 50 Hz. With 0.005 Hz the shape will repeat each 200 seconds. The LFO outputs are connected to the other sections. Thus you can take any of the modulators to control a value in the other section.

Noise

The type combobox selects a noise type. Noise is kind of random values.
Currently there are the following noise types:

• Phased White
• Uniform White
• Pink
• Resonance Pink

More colors and derivatives are planned.

The hold slider sets the sample & hold rate. Moving it sets the rate at which a new random value is produced. In down position new values are produced at the samplerate SR. This means that each sample has a new random value. Moving the slider up produces random values for SR/2, SR/4, SR/8 and so on thus producing lower frequencies. The smooth slider is disabled. The next version of Saccara will support interpolating between the random values to soften the random steps. The modulation section HM allows to control the Hold Time with one of the three LFO's. The modulation section SM is not yet implemented.

Filter

The type combobox selects a filter type. With the filter you can change the color of the noise.
Currently there are:

• Classic LowPass
• StateVariable LowPass
• StateVariable HighPass
• StateVariable BandPass
• StateVariable Notch

The frequency slider selects the frequency at which you want to operate. For a lowpass filter all frequencies below are passed. With the quality slider Q you can adjust the sharpness at the selected frequency. This also is known as resonance. Setting the Q slider to 1.0 produces a self-oscillating effect.

The modulation section FM allows to control the filter's frequency with one of the three LFO's. The modulation section QM allows to control the filter's quality with one of the three LFO's. In this version only the Classic LowPass can be modulated by the LFO's

Channel

The input combobox selects between the noise generator and the filter output as source.

The level slider manipulates the volume which is shown in db. 0 db means full level, whereas -100 db is not noticeable. You can mute the channel without affecting the current volume.

The pan slider moves the sound between left and right position. The center button sets the balance at the center position (0).

The pitch slider changes the playback samplerate. At 1.0 you have the original pitch which you always can reset with the button labeled Original. Moving the slider down changes the playrate down to 1/4 of the original frequency, moving it up produces a higher pitch up to approximately 2.5 SR.

The modulation section AM allows to control the output level with one of the three LFO's.

The modulation section BM allows to control the balance between left and right with one of the three LFO's.

The modulation section FM allows to control the playback frequency with one of the three LFO's.

Use the play and stop button from the toolbar to start the playback. Clicking the stop button will also play a short segment of 882 samples. You can adjust any synthesizer parameter with a slider manually or you can select a modulation source to control the values automatically. Please note, that you can't adjust a slider when a modulation source is selected. The slider will move automatically in correspondence to the modulation depth.

The current version is freeware. You can use it for any noncommercial purpose, but for mutual benefit we would like to get some response from you. Caution!
Sound is starting immediatly after loading the program. This product may be capable of producing sounds which can damage your sound system. Please use with moderate volume settings and use this application with care.
