sound is sampled. The number of channels indicate if the audio is
mono, stereo, or quadro. Each frame consists of one sample per
channel. The sample size is the size in bytes of each sample. Thus a
-frame consists of \var{nchannels}*\var{framesize} bytes, and a second's worth of

+For example, CD quality audio has a sample size of two bytes (16
+bits), uses two channels (stereo) and has a frame rate of 44,100
+frames/second. This gives a frame size of 4 bytes (2*2), and a
+second's worth occupies 2*2*44100 bytes, i.e.\ 176,400 bytes.
