Wwise Help

In Wwise, live monitoring needs to be explicitly enabled. Do so by clicking the Start Capture button, , in the toolbar. Also make sure the Show Live Data option, , is enabled, unless you want to see values back in time. With capture enabled, the Grain Visualizer, Slider Feedback and VU Meter all come to life and make designing with the synthesizer much easier.

Soundseed Grain does not feature a preview mode of the file loaded in it without granulation. One way to audition your file is to right-click in the wavefrom view and select Edit in External Editor, using the editor of your choice. See Managing external editors for audio.

A neat way to have the Position scan your file sequentially for implementing time scaling effects (independent time stretching and pitch shifting) is to assign a Saw up+ modulator to the Position property.

If you make the modulator's Period smaller, Soundseed Grain will scan the file faster. If you like, you can use an RTPC on the modulator's Period. You can also use different waveforms. For example, a triangle LFO will produce ping-pong-like scanning of the file.

For 3D ambiences, you should design your Soundseed Grain patch in such a way that it represents the sound field in its most immersive, surrounding form, like you will want it to play back with 100% spread. Then, Wwise takes care of contracting it in a point source whenever the sound's Spread is smaller than 100.

For creating an enveloping ambient sound in Soundseed Grain, you will typically use a mono or multichannel file, and generate 3D spatialized grains all around you.

The Amplitude property has the same effect as the Level property, only it is expressed in % instead of in decibels, which is usually less intuitive. Its main interest is for producing grains of various amplitude. For example, set Amplitude to 0 and assign Amplitude to a Random+ modulator with Amount 100 to produce grains with random amplitude between 0 and 100%. Alternatively you could set Amplitude to 50 and use a bipolar Random modulator with Amount 50 to obtain the same effect.

Filters are similar. There are as many filters as there are grains playing concurrently; therefore, it is better to use an EQ as an insert effect if the desired filtering is constant over time, for performance reasons (although the cost of each filter is not very significant). However, if you want to produce grains with different filtering, then use the filter with grain modulation.

For implementing engine sounds, you may have imported a recording where each region corresponds to a different RPM or engine regime. Then, your goal is to have the synthesizer pick grains randomly in a region of the file corresponding to the desired regime. This region can be viewed as a macro window in which grains should be taken. One way to implement this macro window is using grain modulation on top of RTPC.

	Note
	Alternatively, you could have used a bipolar Random modulator waveform. In this case the Position RTPC defines the center of the window instead of its left boundary.

	Note
	For engine sounds, it may be desirable to place markers at each explosion and use the "Snap to markers" option.
