I looked around to see who might be singing and playing the guitar.  There was a group of people sitting outside an entrance, and I looked over as I approached to see if one of them had a guitar.  But no, they were just sitting around talking &#8211; no guitar and no singing.<\/p>\n<p>But when I passed the entrance, I looked inside and saw it was a coffee shop.  Way in the back was a guy singing into a microphone and playing his guitar to entertain the diners &#8211; not an uncommon sight.  Mystery solved.<\/p>\n<p>But then I got to thinking &#8211; how had I known it was live music, from clear up the block?  The music I&#8217;d heard had travelled from the back of the coffee shop out into the street &#8211; I was still a good fifty feet up the sidewalk when I first heard it and realized I was hearing live music.  And I hadn&#8217;t just suspected I was hearing live music, as opposed to a recording.  I had been <i>certain<\/i> of it.<\/p>\n<p>If the guy had been singing without an amp, it would have been easy to explain the difference.  There&#8217;s all kinds of phase information in live audio that gets flattened, distorted or just plain lost when played back through a speaker.  Humans are extremely good at detecting subtle textures in sound, and the difference between a live sound source and the poor substitute of playback through stereo speakers is quite dramatic.<\/p>\n<p>But the guy I&#8217;d heard was singing into a microphone.  I wasn&#8217;t hearing his voice and guitar directly &#8211; I was hearing music coming out of an amplifier and speaker.  So why was it so obvious, even from all the way up the block, that I was hearing a live performance?<\/p>\n<p>I have some theories, but I&#8217;m curious to know if anyone else has any thoughts on the subject.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This evening as I was walking along 8th Street I realized that I was hearing live music.
