WOW!!! Thanks. From BBS to Car in less than one hour. =0)

I am actually looking forward to my morning commute tomorrow.

This hack takes the cake of the coolest and perhaps most useful one yet!

I think that people sometimes forget that the empeg is for music. Don't get me wrong, I apprecieate the Flancedoor editor software, the logo editors, the NAS capabilities, the escher lovers, and emptris, but <sheesh>, who has time to watch this stuff while you are in driving a car?

Thanks for the awesome contribution!

Now if I could just get mlord to work on the auto-vol adjuster to harden the knee, shorten the attack, and set the release to infinity.

cheers,

Lothar

Here 'tis Tony. Should be patched over v200 Hijack patched kernel. You should patch it from the same location as a Hijack. i.e. root directory of a v200 Hijack kernel with patch -p1 <timealign.patch

Individual (car/home) settings are getting there. Haven't decided exactly how to remove the glitch yet.

How does this work? I am sorry but I am not a Linux guy so I am a bit lost.

Would it be possible to have a independent patrch to be added to an already hijack-patched kernel, by just using Tony's Logo Editor? I mean: take a standard kernel. Apply the latest HiJack patch (hijack.zimage) with Tony's Logo Editor. Then apply the latest timealign patch (timealign.zimage) still with Tony Logo Editor?

Thank you,

No. The kernel source code must be patched with the HiJack patch, then patched with the time align patch, then compiled to a zImage file then the zImage file uploaded to the player.

Hopefully once Mark returns from whereever he is he can merge the time align code into HiJack and all will be well...

Are you going to be adding an option to slightly (but accurately) lower the volume on the delayed side (I've been following the thread, but I didn't catch any mention of volume adjustment)? With the close proximity of speakers in a car, one of the most noticeable changes to alter the perceived sound stage is volume (balance). I don't normally like playing with balance controls because often they're too rough for fine adjustment. Plus I haven't seen one yet that includes quick-presets. Having your patch presets be able to be called from a Hijack popup would be phenomenal.

Basically you're asking for a more refined balance function, aren't you? So, do you think the distance of the speaker also creates a perceivable difference in volume? That's interesting. I actually thoight about that, but was wondering whether that would be noticeable at all...
However, since we're here, I'd like that too. Hey this is making empeg even more unique than it already is...

I got it to sound pretty darn centered using a 4.1ms delayed right channel. I'm sitting in the seat on the left.

It doesn't make sense that if I delayed the far speaker on the right it will sound centered, but it does. When I try delaying the left, it sounds like garbage.

For example, YYZ's opening sequence with the bells going around in a circle.... a 4.1ms right delay puts the center of that circle on my head. If I delay the left channel it instantly sounds like garbage.

I get channel cutout by twirling the knob to the far ends of the delay scale. Around the moment where the right switches to left and visa versa... there's a place that cuts out. I'm not sure if there is a phased relationship between the speaker causing it to *sound* like nothing, but when I lean in on my tweeter I hear nothing. When I reduce the delay to reasonable levels it sounds super duper.

eternalsun:

I twirled the life out of it last night but couldn't get it to cut out. Also are you sure you have your left and right channels the right way around. You're the only who seems to have the left/right problem. I am quite certain I have left and right correct - I checked it about three times because there are few places where it could get swapped in my code.

As for volume adjustment that is a lot trickier than it sounds. At the moment I am merely delaying samples. Reducing volume as in the voladj code is a fair bit more difficult. I could possibly latch onto some of the voladj stuff and do it there assuming I can attack one channel only.

Suggestion: Try the empeg's balance control. Does it work properly for you?

Sure it makes sense. I have the same setup in my Jeep. The reason why it makes sense is because the speaker on the right is on-axis with your ear. The sound will actually reach your ear faster from the right speaker because unlike the transducer on the left which is off-axis of your head, it does not have to bounce off the right side of the car before reaching your ear. Make sense?

As long as it sounds good! Stick with it.

Now you can get a Mk1 version...

WARNING WARNING WARNING
I do not have a Mk1 so I have not tried this at all. It may not even boot. At times while I was developing on a Mk2 I had issues where the kernel was way broken and the unit wouldn't boot properly. I was able to get out of this each time with little hassle using the standard upgrade program. So don't complain if it breaks your Mk1. If it does an upgrade will probably rescue you.
END WARNING

Get it here

Actually, I could use the most basic installation help... I have it downloaded. I give it a ".upgrade" extension. Rio Upgrade Wizard tells me it's corrupt. I can build PC's with my eyes closed, but this is getting to me... I know it's something dumb, anyone point it out to me?

Use Tony's Logo Editor to send it to the player.

OK,

It's not an upgrade. It's a new kernel. An upgrade includes things like a ramdisk image, player software etc. It needs to be applied using the download.c program or upload included in the logoedit package by Tony Fabris.

Go here for a description of hijack and a link to the logoedit package.

Then run:
upload.exe <patch file> 10000 <com port>

Where <patch file> is the .zImage file and <comport> is just a number i.e. 1, 2 etc. There is no need to rename the file.

The player must be on the AC power supply and you need the supplied serial cable connected to the unit.

Got it, actually was quite easy. I misunderstood it to be attached to the whole program, not just the hijack.

IT WORKS! You're so cool! Thank you! I don't think you need to change a thing. My driver seat is on the left, and I have the left delayed approximately 40cm, did it by ear to get there. Turns out that eyeballing it that is actually the path length difference between the speakers.

Hell yeah!

I had previously offered $50 for getting this done. Where do you want it sent?

That's very much appreciated but I think that you should be giving at the very least half of that to Mark Lord. Without hijack, it wouldn't have been as easy for me. Particularly - there wouldn't be much of an interface to set it up.

I think Sven (smu) made an upgrade file creator/extractor, to turn raw flash images into upload files with control sections and checksums. (I'll need to find it myself, if I want my Gimp logo-editor to read and write upgrade files)

Well, how about I buy everyone a beer next time we get together

The mod works perfectly for me, I was playing all sorts of things this morning on the way to work to experiment with it. Nothing funky, just a nice centered sound. I love it. Now I just need to set my EQ and we're golden.

Got back from vacation.

Yes, I mentioned in a prior post that the balance controls work correctly but the delay stuff seems backwards. That's the reason why I say it doesn't make sense. Just in case, here is how the balance control works. When I set it up for maximum left (bars on the left, no bars on the right side of center) sound comes from the left, and no sound comes from the right.

When I use the delay... it works in the opposite direction!

I'll play with it some more when I get the chance. The strange thing is, like I said, I'm sitting on the left side of the car, and my perception of centered is 4.1ms delayed right. If I put 4.1ms delayed left, it doesn't sound correct or centered at all.

Like I said before, my balance controls work perfectly.
