What sound does an egg make?
Since the beginning of audio, as a hobby many years ago, listeners have
wanted reproduced sound to be more like what they experienced in real
life. Make it sound real, has been the cry most often heard. What to do?
Well, first of all, the playback system must be impeccably flat in it's
frequency response. This accuracy should be defined in terms of a
performance envelope no larger than 2db, ie ±1dB from 20 Hz to 20 kHz.
The playback music system should be made to be very quiet in terms of
signal to noise and free of additive elements like distortion, both IM and
THD. The sounds experienced in a good listening room, (one with a
reverberation time of between .3 to .4 seconds) would have a similar tonal
character just about anywhere in that room, assuming the corners, along
walls, the doorway guys and positioning oneself behind the playback
transducers are out of bounds to anyone desiring to experience this aural
The playback room would also have to be free of external and internal
noise sources such as traffic, heating and cooling air movement systems,
transformer buzz from fluorescent lights as well as wind and other natural
phenomena. If a listener was to partake in the often observed audiophile
bump and grind review, ie stand, sit down and again ad nauseum all
around the room, the sound should remain remarkably similar for most
locations especially within a 60° arc of the speaker system. My friends,
is this not what happens in real life when someone speaks or when a
musician plays an instrument? Are the sounds not remarkably similar
throughout the listening space?
If a speaker system was created, that had a dispersive character where the
off-axis energy both vertically and horizontally, had a similar tonal
character as the first arrival, otherwise known as the direct sound, and
produced these at the same energy level or loudness, then might this be
the definition of a true point source?
Waveform invites all enthusiasts to Rm # 602 during HI-FI '96 for a
chance to experience a device, the Mach 17 which brings us all as a
hobbyist group of listeners, closer to this elusive grail goal better
perhaps than any other device yet made. Waveform doesn't claim to be able
to give you all of these features in the Waldorf-Astoria in NY but we will
make every attempt to come as close as possible under "show conditions".
For those seriously interested in how this all came about, one technical
presentation will be held in Rm # 602 on Thursday, May 30th, at 3 PM.

To keep this conversation as light as possible, here is the joke of the
month probably told before. How does an audiophile point himself out in
a group of listeners? He's the first person to start talking after the
music begins to play.
