/**

 * Return the samples of a frequency sweep. The sweep may be divided

 * in segments, each using a different waveform (or noise), and each with

 * a start and end frequency.

 * @param {!Array<Object<string, string|number>>} sequence The sequence.

 *   Each item in the array must have the properties:

 *     start: Integer value, the start frequency of the segment.

 *     end: Integer value, the end frequency of the segment.

 *     time: Float value, the duration of the segment. 1 = 1 second.

 *     wave: String, "sine", "square", "triangle", "sawtooth" or "noise".

 * @param {number} sampleRate The sample rate.

 * @return {!Array<number>}
