Example 1 with AudioStream

use of ddf.minim.spi.AudioStream in project Minim by ddf.

the class Minim method getLineIn.

/**
	 * Gets an {@link AudioInput}.

	 *            int: how long you want the <code>AudioInput</code>'s sample buffer
	 *            to be (ie the size of left, right, and mix buffers)
	 * @param sampleRate
	 *            float: the desired sample rate in Hertz (typically 44100)
	 * @param bitDepth
	 *            int: the desired bit depth (typically 16)
	 * @return an <code>AudioInput</code> with the requested attributes

Example 2 with AudioStream

use of ddf.minim.spi.AudioStream in project Minim by ddf.

the class Minim method stop.

/**
	 * 
	 * Stops Minim and releases all audio resources.
	 * <p>
	 * If using Minim outside of Processing, you must call this to 
	 * release all of the audio resources that Minim has generated.
	 * It will call close() on all of them for you.
	 * 
	 */

Example 3 with AudioStream

use of ddf.minim.spi.AudioStream in project Minim by ddf.

the class Minim method getInputStream.

/**
	 * Get the input as an AudioStream that you can read from yourself, rather
	 * than wrapped in an AudioInput that does that work for you.

	 *            buffer to be.
	 * @param sampleRate
	 *            float: the desired sample rate in Hertz (typically 44100)
	 * @param bitDepth
