Thanks for the reply.
Since I wrote that I have found myself just using PEQ and Ambiophonic plugins without DRC.
This keeps the presence of the music (particularly bass) whilst more or less preserving DRC's stereo image.
I'll try playing around with the settings as you suggest. |

Some time ago I bought the ambiosonicDSP plugin hopeful that it would help me in Car audio. I've got a classic car with fixed positions for the speakers and have an excellent center image but no width dus to the position of the speakers.
With the beatles ambio demo track that width was there so I knew there was something to be had with ambiophonicdsp in the car.
But to use it without a Car PC I'd have to convert my tracks to a USB drive with the vsp plugin.
Every time I run the vst from within DBPoweramp the delay setting gets reset. So basically I'm stuck with the standard delay setting although I'd rather use/try different settings. Is there any way to fix this behavior?
I have ran the MAP vst plugin which has a slightly longer delay with great results but then I lose the ability to make the center a bit louder and of coarse also no delay changes to play with.
It would be a lot more fun for me to be able to have at least default to the last used settings and not a reset of delay like it is currently.
I'd be in heaven if this could be solved
I've seen more forum input asking the same in my searches but something like this has to be easy to solve right? I'd be happy with a work around as long as I can try different values that stick after restarting the plugin with a host like DBPoweramp. |

wesayso to electro-music.com
I will send you a PM about a special version we have set up. It needs testing. _________________ --Howard

Thanks for the welcome and the PM,
Replied with first findings. I will add to it later after I have used more settings .
I'll be sure to try it with the home setup as well with the speakers in the right position for Ambiophonic. Just need to find the time to test it all.
Many thanks for the quick reply. |

I have just setup AmbiophonicDSP VST in JRiver Media Center 17. How does it handle 8 channels (7.1)?
You cannot choose which channels are processed from the VST host, so I assume it feeds all channels. It appears to apply to the surround side/rears, but hard to tell. |

The AmbiophonicDSP VST has only 2 in and 2 out. Which channels are determined by the VST host you are using. I'm unfamiliar with the one you are using.
Good surround can be gotten from stereo recordings by using 4 speakers, 2 close spaced (17 degrees) in the front, and two in the rear, also close spaced. Send the left out of the AmbiophonicDSP to both of the left speakers, and likewise for the right. Adjust the rear volume to be about 6 to 10 dB below the front. This is called Panambio.
If you have 5.1 or 7.1 source material, don't use the AmbiophonicDSP.
If you want, you can run multiple instances of the AmbiophonicDSP and experiment with multiple channel setups. This is possible if your VST host program supports it. But the beauty of the plugin is that it make stereo recording sound much better with just two closely spaced speakers.
I recommend Reaper for multi channel setups, unless you have one of the excellent RME multi-channel audio interfaces. Their UFX and UFC are superb for routing multi-channel environments. _________________ --Howard

Thanks. I have multiple "zones" setup in JRiver with individual DSP/VST setups. One is setup for 2ch stereo to output from an Asus Essense ST card SPDIF out to a receiver/amp, which I will enable the Ambiophonic DSP in.
I was testing multi-channel music (Pink Floyd DSOTM) with the Ambiophonic DSP enabled which is 4.1 format (actually 5.1 with silent centre), which plays via a separate multi-channel "zone" via HDMI to receiver/amp and Ambiophonic appeared to still function on the fronts, but it also sounded like it processed the surrounds as well.
JRiver only reports 8 channels enabled in DSP engine for multi-channel (which is the total number of speakers I have setup). Other than that I cannot see what it passes to a VST plugin internally. |

MAC OS version?? |
 |
|
Hello! Just paid up but still waiting for a download email..
I'm wondering a few things.. hope I am at the right place
1) When might there be a Mac version of the VST?
2) I am just wondering.. is it possible to keep the 60 degree of the ordinary speaker setup but still be able to use the AmbiophonicDSP? Then the comparison between stereo and ambio would even be more apparent..
3) at 16 degree apart, should the two speakers be firing in parrellel? meaning straight at the listener's left and right without any cave-in angle?
4) has anyone try this ambio with a HRTF implementation?
Thank you so much!! |

Nothing is in the works, ATM.

Crosstalk cancellation works best with the speakers closely spaced. If you use wide spaced speakers you will get the hole-in-the-middle problem. But, if you must, increase the delay setting to maximum, or near maximum. Adjust the Zentrum control to help as best you can.

I doubt if it makes much difference; it would depend on the particular speakers.
| Quote: | | 4) has anyone try this ambio with a HRTF implementation? |
HRTF, Head Response Transfer Function, is not used in our plugin, or any other one that I know of. The HRTF of every person is different anyway. Some HRTF experiments when played back with headphones place sounds very accurately for some listeners, but have no appreciable effect on others. That said, not everyone hears the effectiveness of crosstalk cancellation either. _________________ --Howard
