Unity: capturing audio from multiple microphones
Posted by Dimitri | Filed under Featured, Programming
As stated in the title, this Unity scripting tutorial explains how to select and record and playback audio from a list of connected microphones. It’s somewhat of a follow up of the previous post Unity: Capturing audio from a microphone. So, for those who are after a step by step explanation of how to capture audio from a single microphone in Unity, please read the previous post. The code featured in this tutorial has been developed and tested using Unity 3.5.4f1 at the editor and a as a standalone Windows application. A sample project with all the code discussed in this tutorial is available for download at the end of this tutorial.
Just as a reminder, to capture audio from a microphone in Unity, all that is necessary is to call the static Start() method from the Microphone class. It returns an AudioClip that can be played back using an AudioSource. However, this time, it’s now important to know how many microphones are connected to the computer and the recording capabilities of each microphone. This is going to be done by calling the static Microphone.GetDeviceCaps() method for each microphone and save the obtained information at two the integer arrays.
Unity: Capturing audio from a microphone
Posted by Dimitri | Filed under Programming
This Unity programming tutorial explains how to create a Unity script to capture the audio from a microphone. It also shows how to playback the captured audio and the necessary steps to check if there is a microphone present and its recording capabilities. The code featured in this post has been developed and tested using Unity 3.5.4f1 at the editor and a as a standalone Windows application. A sample project with all the code discussed in this tutorial is available for download at the end of the post.
To capture the audio input from a microphone in Unity, one can simply call the static Start() method from the Microphone class to start recording. This method returns an AudioClip that can be played back using an AudioSource. And that’s exactly what the script explained in this post will do. However, to avoid exceptions from being thrown, there is a simple verification to detect if there’s a microphone present prior to calling this method, and also, the mic audio capture capabilities are checked. Luckily, the same Microphone class also offers public members and methods that aid in accomplishing the two aforementioned tasks.
Unity: displaying the video input from multiple webcams
Posted by Dimitri | Filed under Programming
This post explains how to capture the images from a web camera connected to the computer and use them as a texture in Unity. However, this tutorial focuses on switching between the video inputs from different webcams attached to desktop computers (PC and Mac). However it should work on Android with some minor modifications. The code featured in this article has been developed and tested using a free license of Unity 3.5.3f3. As usual an example project with all the code featured in this article is available for download at the end of the post.
Before explaining how to choose from a list of multiple connected webcams to render from, let’s see how to preview the captured images from a single camera. Doing that in Unity is very simple and it can be achieved with just a few lines of code. Take a look at this C# script: (more…)
Unity: Making a simple audio visualization
Posted by Dimitri | Filed under Programming
As stated in the title, this Unity programming tutorial shows how to create a simple audio visualizer. This post focuses on explaining the necessary requirements in obtaining the audio data from the current music being played, and how to process this data to create a audio visualization. It won’t have detailed explanations on how to create a specific effect for an audio visualization. The code featured below and the example project were created and tested in Unity 3.5.2 .
For this post, the audio spectrum data will be displayed as a line using a LineRenderer component and will also feature some cubes that will fall from the top of the waveform, much like the little white bars above the spectrum found on the Windows Media Player “Bars” visualization. However, this visualization will be 3D and not 2D and will render a waveform and not bars.
To achieve that, a script and the following elements will be required: (more…)
Unity: Creating GUI transitions
Posted by Dimitri | Filed under Programming
This Unity scripting tutorial shows how to manipulate the GUI system origin to create an animated transition, so you can make your GUI’s look more interesting. To keep things simple, this post shows how to create an horizontal transition between two Text Areas using a couple of buttons. All code featured below is available for download at the end of the post.
To achieve an animated transition, the origin of the GUI system must be manipulated. This is done by changing the elements of the matrix that sets the rendering reference point of the GUI elements. Conveniently, Unity allows us to do that by manipulating the GUI.matrix values. So, the script requires a Matrix4x4 object. Also, to make the code more readable, a Vector3 is going to be created, also making it easier to translate the GUI system origin. Here’s the script:
