  WhiteCap as a Standlone Application  
  Although WhiteCap runs as a visual plugin inside audio players such as iTunes, it can also run as a standalone application that can visualize any sound source. This is essential when you want to visualize audio from a live performance or social event using a microphone or an audio line-in input. You receive WhiteCap Standalone when you upgrade to WhiteCap Platinum.

Use & Terms

In general, you can use WhiteCap for private, non-commercial events at no cost, but you must contact us for a commercial license if you want to use WhiteCap in any commercial, official, or public capacity. This software is the art of Drew O’Meara, and we can’t keep our doors open without community support. Kindly see the license agreement for details and terms of use.

Instructions
  1. Start WhiteCap Standalone. You can either search your system for "WhiteCap Standalone" or you can navigate to it directly:
    • Windows:
           Start Menu > Programs > WhiteCap
    • macOS:
           /Users/(you)/Applications/WhiteCap
  2. When WhiteCap Standalone is running, switch to the desired audio input device by using the menu: Settings > Audio Input Source
    You can also change the current audio input source by right-clicking (or control-clicking) on the WhiteCap Standalone window.
  3. Check that the volume level from the current audio source is not muted and is turned up. People sometimes have everything set up properly but don’t notice that the input is muted on the device itself or in the system's audio settings. If you're looping back audio from your system (see below), ensure that your system volume is turned up!
  4. Adjust the visual responsiveness in WhiteCap to your liking using Settings > Audio Sensitivity or using the shortcut keys: + -
  5. Note that the setting Try Other Audio Sources When Silence Detected is enabled by default. This means that if silence is detected on the currently selected audio input source for more than 15 seconds, then WhiteCap will begin checking other audio sources for activity. If it finds active audio activity on another source, it will continue to use that audio source until there's activity on the original source. When that happens, WhiteCap will immediately switch back to displaying the original audio source. This feature is particularly useful when WhiteCap is running as a screen saver since it's nice for any active audio to be automatically visualized.

Visualizing Audio From Other Programs

On Windows, there are two methods to visualize audio coming from a Windows program or web browser. Some Windows systems have a virtual sound device named Stereo Mix or What You Hear, allowing programs like WhiteCap Standalone to visualize your system's output audio. For example, audio playing from a web browser can be tapped and visualized in WhiteCap Standalone. If your Windows system supports this, follow these steps:
  1. In Windows, open Control Panel > Sound
  2. Select the Recording tab
  3. Right click on the recording device Stereo Mix (or similar) and select Properties
  4. Within the General Properties tab, select Use this device (enable)
  5. Restart Standalone and follow the above instructions to change the audio source.

The second method to visualize audio from a program on Windows is to use SoundSpectrum Audio Cable, included with WhiteCap Platinum. This is a Windows audio driver we bundle that can be set up as a system output device, allowing system audio to be piped to programs like WhiteCap Standalone. You can learn how to set it up here.

On macOS, if you want to visualize audio from an application, your only option is to install a third party application such as Loopback by Rogue Amoeba. LineIn and SoundFlower intalled together are also an effective (free/opensource) solution.
