Live, Records and acoustic. Why so difference?

What we hear in recording studio, in live concert and purely acoustic presentation, are they the same?
The answer is certainly, NO!

In recording studio, they provide the best ambient acoustic for different instrument.
  • They use best instruments.
  • They use the best microphone to pick up signals from instruments.
  • They use the best balanced/digitized mixer to mix all the instrument together.
  • Then, pan to left or right the position of each instrument.Trying to get the most real positioning.
  • Then, equalize if they feel all sounds are blended up till some instrument could not stand out.
  • They use the best monitor (but those with weak bass) to examine the clearance.
  • Then they cut off the unwanted acoustic noise of each songs.
  • Remix it into 24bit, full bandwidth, burn to CD with the best machine.
  • Remixed and equalized means not original already.
  • sell.

So, what bout live?

  • They use the best instruments also.
  • But the room ambient is not that desired kind, but is also the one that recording studio can never ever achieve.
  • They use the best microphone, and signal cable,
  • But they need to control feedback.
  • Hence, a parabolic equalizer is introduced to each instrument, to cut off the aggressive feedback frequency.
  • They cut off the ultra low frequency to increase the clearance of each instrument, since the ambient is big, the audience at back row will only hear some annoying ultra low bass.
  • It become narrow bandwidth.
  • It doesn't sound original after all these major 'operation', Especially if the instrument used is not having a good pickup.
  • Some very pro pro audio master use stereo in their concert, hence they can pan the position of each instrument.

Acoustic presentation?

  • Normal instruments, no mic, low volume (CD volume), no feedback.
  • Every instruments' position is clearly heard.
  • But the volume may not be balanced or even.
  • PA system or mixer is unavoidable if blending guitar into a brass band or string band.
  • It's the most natural sound.


So, people prefer live or concert? It depends. If he wants ultimate clear sound, like what you expect to hear the difference between Martin guitar and Taylor's guitar, then CD is the choice.

If you prefer Live mood, the sense of 'big', you'll like to choose concert.

No one can overtake anyone. Even with the best audio equipment!

when compare live concert and studio recording, I prefer the third type, that is , recording of live concert.

I find the third type very powerful, impressive sound, which studio recording doesnt offer to me. why? what make the difference?

of some live recording are very poor, sucks! especially by hong kong, taiwan and malaysia artist concert... but now, some taiwan artist preduced concert in taipei, improved very much the sound effect..

Howver, if you are listening to Norah jones and Joe Pass stuff.. Or maybe some jazz vocal performance, you may prefer studio sound. The techniques and emotion of their singing is so crystal clear.

Of course, if for pop song, you won't want to listen to their voice so clearly. Pop singers tends to be powerful and loud.

If listen to Jay chow, even if the positioning is not very correct, the sound is tuned another way , it's okay i think..

if listen to Norah Jones, best is to her concert , listen un plug, live...

Yes! Unplug, is the best choice.
That's also what audiophiles trying to create.

It's a dilemma, next time i'll tell you what's the complicated part that i don't understand, in another post perhaps.
