how is spacial imaging increased for iems? - Page 4

post #46 of 51

Home theater was definitely an eye opener for me.  I pretty much gave up on two channel after going through all the extensive delays, positioning, speaker distance measurements, and equalisation setup routines in HT, but it was well worth it.  The dollar goes further in HT than conventional 2 channel without a doubt IME.

When I have friends over, I'll put on some really well recorded music with the Yamaha 7:1 stereo DSP and I'll ask them to close their eyes and point to the various instruments in the orchestra. Then, once they've done that, I'll hit the switch that bypasses all of the signal processing and patches through the amp direct. The sound stage shrinks by half, the tone gets thin and the feeling of depth completely flattens out to create a small opaque plane of sound in front. It's amazing what a well designed DSP can do. I think that's the future of home audio. I'd like to see DSPs as downloadable software, so you could have a bunch of different venues and sound fields available. Kind of like the holodeck in Star Trek.

I believe DSP is definitely the way forward...I have a slew of EQ, Crossfeed and Isone Tone plug-ins for use with JR Media.  The top line early 2000 BMW's used to have a button that engages the time delay DSP and images everything properly...the current models and previous models dropped this feature out altogether.

With phase delay you can change perception of space.  I'm guessing you can add phase delay to different driver to cause separation of different frequency bands on the IEMs.  So, this can be benefits of multiple driver IEMs.  I wonder if this why the new JH13 pro is called frequency phase??

Multiple driver IEMs typically have heavily skewed phase response. The JH13 FP was designed to give you a more even phase response. I doubt you would get a real beneficial effect by deliberately distorting the phase by this passive method.

 

Remember that while some sound localization is done by L/R phase difference, you really do not want to introduce a left/right imbalance.

 

Better to use a DSP.

A DSP can modify it intelligently, not just through error.
