Great strides have been made in the field of sound recording over the last couple of decades. We've seen (in no particular order):
- Digital recording (both tape and disk based)
- Multichannel recording
- Multichannel mics (think Holophone or any other mic that captures more than a stereo image)
- improved contact mics
- improved hydrophones
- sub- and super-sonic mics (think miss that can capture below 20Hz or above 50kHz)
…and many more.
But, what's next? What's that next big tech that will be a true innovation? I'm thinking something akin to what 3-D capture has done for the visual medium (think Avatar).
And let's keep this thread clear of any reproduction systems, ie. 5.1, 7.1, etc. I'm interested in the future of HOW we capture sound, not how it is played back.
UPDATE:
I've had the joy of using the Sanken CO-100k on my latest project and I have to admit, it's kind of a game changer for recordings that ultimately will be sped way down to fractions of their original speed. The specs show it can capture frequencies up to (and beyond?) 100kHz so, once you've slowed it down to half-speed, you're still working with a sound with 50kHz resolution. (This assuming you have clean preamps and a pro recorder like a Sound Devices or similar.) We were able to do amazing things with the tiniest of sounds, things that would have been possible with other professional mics like a Neumann 191 but would have required major rebuilding or augmenting of high frequency content.
