- * p5.Convolver extends p5.Reverb. It can emulate the sound of real

- *
- * Convolution multiplies any audio input by an "impulse response"
- * to simulate the dispersion of sound over time. The impulse response is
- * generated from an audio file that you provide. One way to
- * generate an impulse response is to pop a balloon in a reverberant space
- * and record the echo. Convolution can also be used to experiment with
- * sound.
- *
- * Use the method createConvolution(path) to instantiate a
- * p5.Convolver with a path to your impulse response audio file.

/**
- * A phrase is a pattern of musical events over time, i.e.
- * a series of notes and rests.
+ * p5.Convolver extends p5.Reverb. It can emulate the sound of real
+ * physical spaces through a process called
+ * convolution.
*
- * Phrases must be added to a p5.Part for playback, and
- * each part can play multiple phrases at the same time.
- * For example, one Phrase might be a kick drum, another
- * could be a snare, and another could be the bassline.
+ * Convolution multiplies any audio input by an "impulse response"
+ * to simulate the dispersion of sound over time. The impulse response is
+ * generated from an audio file that you provide. One way to
+ * generate an impulse response is to pop a balloon in a reverberant space
+ * and record the echo. Convolution can also be used to experiment with
+ * sound.
*
- * The first parameter is a name so that the phrase can be
- * modified or deleted later. The callback is a a function that
- * this phrase will call at every step—for example it might be
- * called playNote(value){}. The array determines
- * which value is passed into the callback at each step of the
- * phrase. It can be numbers, an object with multiple numbers,
- * or a zero (0) indicates a rest so the callback won't be called).
+ * Use the method createConvolution(path) to instantiate a
+ * p5.Convolver with a path to your impulse response audio file.

- * to play the sound (in seconds from now),
- * and a value from the sequence array. The
- * time should be passed into the play() or
- * start() method to ensure precision.
- * @param {Array} sequence Array of values to pass into the callback
- * at each step of the phrase.
+ * @param {String} path path to a sound file
