Why no index to indicate proper listening level?


I recall that a well respected engineer said that there was only one correct listening level for any given recording. I believe that aside from the people who favour smallish bookshelf speakers fed by a high quality low power amp and therefore, through choice or need, stick to polite levels, the point of an audiophile quality system is to faithfully reproduce the musical event. This, invariably, means that the music gets to be loud at times, either because of the dynamics involved (such as orchestral music) or simply because modern amplified live events are loud all the time. Why is there not some kind of standardized reference built-in to a recording (would probably be quite simple with digital) indicating what is the optimal and realistic level at which the recording would sound right? This would certainly separate the grain from the chaff system-wise. I am certain that a lot of highly touted systems (at least by the salons selling them), mostly British but not all, that are demoed at such polite levels that a crescendo is the only thing waking the listener up from his stupor, would run out of breath real quick. On the other hand, Godzilla like classical guitars would be avoided. My question then, why no standardized level when somehow people fret over stereo imaging and timbre, that can only vary in accordance with the volume level, not to mention distortion and hard clipping.

Sugarbrie brings up an interesting point about the preamp setting the level automatically. Only problem with this is his previous disclaimer. Due to different loading characteristics of the room, various speaker sensitivities, etc... the preamp would need some type of "acoustic feedback interpreter" to work properly. After all, having the preamp adjusted to preset point using speaker that were 88 db's would present a VERY different volume using speakers that were 93 db's. The "automatic" volume would need some way to measure the in-room volume and compensate accordingly.

This IS something that is quite intriguing though if you think about it and does have potential. A test tone recorded at the average level of the disc could be played, the system adjusted automatically to a preset in-room level that the engineer / artist thinks works best for that specific recording and the listener sits back and listens. Of course, this system would need to be manually defeatable for those times that you want it either louder or softer. The only problems that i see with the "auto set" system is that one might run into severe clipping with inefficient speakers / underpowered amps or could also go the opposite route of being too quiet in some passages. Material might not be heard / fully understood due to being too quiet due to some rooms possibly having a higher noise floor.

I think that this COULD produce better overall recordings, as both the artists and recording engineers might become more aware of the sonic importance of dynamic range. Sean
