userStartAudio() starts the AudioContext on a user\n * gesture. The default behavior will enable audio on any\n * mouseUp or touchEnd event.

individual\n * \n * audio frequencies within a waveform.
\n *\n *Once instantiated, a p5.FFT object can return an array based on\n * two types of analyses:
• FFT.waveform() computes\n * amplitude values along the time domain. The array indices correspond\n * to samples across a brief moment in time. Each value represents\n * amplitude of the waveform at that sample of time.
\n * • FFT.analyze() computes amplitude values along the\n * frequency domain. The array indices correspond to frequencies (i.e.\n * pitches), from the lowest to the highest that humans can hear. Each\n * value represents amplitude at that slice of the frequency spectrum.\n * Use with getEnergy() to measure amplitude at specific\n * frequencies, or within a range of frequencies.
FFT analyzes a very short snapshot of sound called a sample\n * buffer. It returns an array of amplitude measurements, referred\n * to as bins. The array is 1024 bins long by default.\n * You can change the bin array length, but it must be a power of 2\n * between 16 and 1024 in order for the FFT algorithm to function\n * correctly. The actual size of the FFT buffer is twice the\n * number of bins, so given a standard sample rate, the buffer is\n * 2048/44100 seconds long.
