Alright get it here:

http://www.edmi.com.au/dl/Hijackv200+Delayv10.mk2.zImage

It's based on v200 Hijack and 2.0b11 kernel. Mk2 only at the moment I'm afraid. I should be able to do Mk1 soon though. Let me know if you are a Mk1 user.

Look for "Left/Right Time Alignment" in the Hijack menu. Pretty self explanatory really. Adjust the time in 0.1ms increments and it gives you approximate distance in centimetres. When it says 1.0ms Left that means the left channel is delayed by 1.0ms.

There are some definite clicks which I know about when changing the delay. I should be able to fix this, but I wanted to get it out there first.

One thing I have noticed is that since 2.0b11 and running on home power, my RioCar seems to start the VFD dimmer than 100% sometimes. This could be from my messing but I doubt it. Has anyone else seen this? Or could my RioCar be faulty?

Oh and I do everything before Voladj so that might cause some problems. However given the latency in voladj and the maximum of 12ms delay, I doubt you'll have problems.

Hey, do you have a kernel patch available instead? I have a few other customizations in my kernel that I don't want to lose...

Sorry not yet . The eagerness of everyone has caused me to release it as quick as possible.

Also I am kinda new to this patch thing. Can you give me a quick rundown on how to generate the patch? I'm not sure I correctly the applied the voladj and rdsfake patches to the 2.0b11 kernel (one had an error). I have only changed a few sections, so I am going to go back and tidy things a little, so I can generate a nice patch for everyone.

As I understand it I need an unadulterated, 2.0b11 + rdsfake + voladj in a separate directory.

What's the command from there? I assume this should be run from the root of the source tree?

Thanks,

can you make it so that it save the settings for AC and Car power because at home the right speaker is closer and in the car well its left hand drive

Yes Yes, that will all come in time. This is really a test release to make sure that the concept works.

Like I said there are bugs (clicks when adjusting for example) and also deficiencies.

At the moment I just want to hear if it works or not.

Can you make it so I can hear the right channel when I drive to work in the morning and then the left channel (delayed by about 1 hour) when I drive home at night? Oh, for all cumulative tracks too. It might need a bit more buffer space, but it would be cool to be able to hear all the same tracks on the drive home without having to use repeat or a looping playlist.

And maybe we can get an editor made so that we can make our own panning audio & reverb effects to go with the Flancedoor animations.

Think you can whip that up tonight sometime? Ok, maybe I'm getting a bit carried away now.

>> (delayed by about 1 hour)

HAHA!!!
That's hilarious...but it makes me need to ask...
You're only at work for about 1 hour??

you people dont want much do ya?

edit:
just downloaded the hack. OMFG it's amazing! Only tried it with headphones and upto 1ms you can head the difference panning to the left or right. Past that the brain gets confused and blurs the image considerably. I imagine it'll be better in the car.

I don't have it running in the car while I'm at work. The drive takes me the hour.

So has anyone tried to dial out the delay in a car yet?

hybrid8: what are you trying to say? Have I not done enough for you in the past 2 days? Anything is possible if you really want it (and have enough spare money)

Have I not done enough for you in the past 2 days?

He's just yankin your chain.
10 versions in 2 days? you should be able to surpass hijack by the end of next month!

I tried it out in the car and guess in my excitement i locked the keys in my car. Dammit

Aaah Murray I see where you found me....

I know he was yanking my chain. I guess I didn't reflect that in my reply. Either way this is only the first version. I didn't do the hijack thing. My v10 mean v1.0 which you will catch in the display when you boot.

acurasquirrel: ooh bugger

BTW: I forgot to add the standard disclaimer.

If your empeg blows up because of this hack then well blame yourself for trying. Not trying to be harsh - just stating the bleeding obvious.

well the main thing is, is that it works awesome in my car. Thanks man

I tried it in the car to work today... There was some difference but I couldn't say wether it gave a left/right movement of the music... Do you notice any difference when using high volume, high bass or something like that?

Well all I can say is that the channels are definitely delayed from each other so unless those digital time alignment systems do something else (I doubt it) then it should work.

You should be able to close your eyes and feel like you're sitting in the middle of the car. Try setting it to zero delay and put your head over the centre console (probably right in front of your empeg). That's how it should be.

Speaker placement and setup (splits vs coax etc) will make a fairly large difference I would expect.

It may be that my hearing isn't really trained either :-)

Bruno, any plans to add this to your HiJack FAQ?

You won't notice it with source material that's mono or has poor stereo imaging. Try it with some nice acoustic music that's well recorded, it'll be more obvious.

Why wouldn't you notice it with mono? Left and right may play the same sound, but the timing can still be different.

Yes, i'll add iit. (and the name's loren, not bruno... heheh.)

Loren, damn, sorry about that! I was just talking about Bruno to another user (Bruno was kind enough to help me set up my AudioGrabber). I swear I knew it was you and was reading the FAQ right before I happened on this thread!

(embarassed - walking to corner)

Make a directory that contains the source code before your edits (let's call it hijack.v200). Make a different directory at the same level that contains the source code after your edits (let's call this one hijack.v200.ta). To be clear, these two directories should be subdirectories of one parent directory, so that they are direct siblings. Make sure that you are in that parent directory so that you can see both source code directories. Now enter the command ``diff -ruN hijack.v200 hijack.v200.ta > ta.patch''. This will create a recursive unified diff that includes brand new files and write it to the file `ta.patch'. (Since it includes brand new files, the new source tree should not contain compiled object files and whatnot. It should be as pristine as possible.) (Also, for the record, mlord uses the diff command ``diff -u --recursive --new-file --exclude=zImage --exclude=config.ini --exclude=.* --exclude=*.patch --exclude=buildit --exclude=defconfig <orig> <new>''. The `--recursive' and `--new-file' options correspond to my `r' and `N' options. The rest is for his convenience and should be fairly obvious.) (Oh -- you'll have to make sure that you're using a GNU diff. If you get an error that the -u option is unknown, go download it. It's much better than anything that a more standard diff can give you.)

Thanks Bitt,

I will do a few fixes and add some things like car/home options and some presets in the next few days and try and get a patch for everyone.

Ok, I've been testing it for quite a while now, in my car. Absolutely great job! I took a song with the singer's voice well placed in the middle of the stereo image, closed my eyes, and started to move it right and left until I centered it right in front of me. Absolutely fantastic! I've been waiting for this for such a long time! Thank you, really! As I said before, this was the only real problem in my car installation, or, at least, the only one i really really cared. Now it is fixed!

Now, trying to be more constructive, I think that yes, if you could eliminate the glitch when changing the delay value it would be perfect. And I also agree very much with the suggestion to separate in car and at home settings. Great idea that about the presets, too. And I would also suggest to add a bar with a slider to give a visual indication of the current cfg. Besides that, it looks simply perfect to me. I did'n find bugs of any sort, and I used it now for a couple of hrs continuously.

Again, thanks!!!

Glad to hear it works

Someone has reported that he had the channel he was delaying would just cut out for some reason. I haven't had it happen, and you haven't either it seems.

1) The glitch will almost definitely disappear (or at least be greatly reduced).

2) Car and home settings are coming. I'm running out of flash storage space though I think. It may have to become an config.ini setting and the player simply remembers where it currently is (Car/Home). It will allow you to adjust it once running - you'd then have to copy the values to the config.ini file later on - I'm not sure (haven't looked) to see if Mark has routines for adding to/editing config files.

3) As for the slider bar, I'm not exactly sure what that would show. Obviously no delay is middle of the bar, but if I delayed the left by 3ms (out of max of 12.7ms) what would it be? I can probably do it, I'm just not enitrely sure what you want or what it would show.

IMHO the slider bar would show the center of audio NOW.
For example, no delay shows
||------------+------------||
and delayed the left channel of e.g. 3ms (so the center for the left seat will move to it):
||--------+---|------------||
or similar.

Ive had a channel completely cut out on me as well
