关于sound函数：（此介绍来源于MATLAB 2018a帮助文件）
sound
Convert matrix of signal data to soundcollapse all in page
sound(y)
sound(y,Fs)
sound(y,Fs,nBits)
Description
sound(y) sends audio signal y to the speaker at the default sample rate of 8192 hertz.
sound(y,Fs) sends audio signal y to the speaker at sample rate Fs.
sound(y,Fs,nBits) uses nBits bits per sample for audio signal y.
y — Audio data
column vector | m-by-2 matrix
Audio data, specified as an m-by-1 column vector for single-channel (mono) audio, or an m-by-2 matrix for stereo playback, where m is the number of audio samples. If y is an m-by-2 matrix, then the first column corresponds to the left channel, and the second column corresponds to the right channel. Stereo playback is available only if your system supports it.
Data Types: double
Fs — Sample rate
8192 (default) | positive number
Sample rate, in hertz, of audio data y, is specified as a positive number from 1000 through 384000. Valid values depend on both the sample rates permitted by MATLAB® and the specific audio hardware on your system. MATLAB has a hard restriction of 1000 Hz <= Fs <= 384000 Hz, although further hardware-dependent restrictions apply.
Data Types: single | double
nBits — Bit depth of sample values
16 (default) | 8 | 24
Bit depth of the sample values, specified as an integer. Valid values depend on the audio hardware installed. Most platforms support bit depths of 8 bits or 16 bits.
