Default What will the next breakthrough in Audio be?

Or will there only be refinements from now on?
Seems like the technology has not advanced much over the last decade except for maybe digital recording/compression/encoding. Speakers and amps are better but fundamentally the same. Here's some things I'm looking forward to:
1. Wireless speakers. These will happen once we figure out a practical way to transmit power wireless-ly or maybe when batteries become really good.
2. Directed sound. People have tried it with some success but with poor efficiency and fidelity. Possibly eliminates the need for wireless speakers.
3. Big sound in a small box. This is one area where things have been getting better. It is amazing how much sound they can get out of those little bluetooth speakers these days. Too bad the sound isn't very good.
4. Direct sound-brain interface. Imagine the soundstage!

5. Stereophile files for bankruptcy.

I think the 3rd one is more feasible

On a more serious note, the technology of creating sound in space by "beating" 2 ultrasonic sound beams by creating nonlinearities, so you hear the difference frequency, is fascinating. There's one or two products out there, eg Soundlazer, but there's a long way to go...

The general trend is to abandon the old high Qts (more then 0.1) drivers that achieves a flat response by the resonant behaviour of the driver and enclosure. Once you get some real Bl and some low Qes and Qts (below 0.1 - Qts=0.01 would be even better) and you shape the response by DSP, you can start to get some real efficiency and a much improved transient response. A sloppy resonant behaviour (Q above 0.1) can never achieve any precise control over the cone.

B&C IPAL are great early examples of this trend.

Cheers,
Johannes

We are still waiting for full surround sound. 3D soundfield with headphones off a mobile phone will be a good step forwards.
