Is it possible to use a popup similar to the fader?

Ive had a channel completely cut out on me as well

acurasquirrel, you were the person I was talking about.

Probably not since I think the volume/balance/fader/loudness/beep volume popup stuff is done in the player software not the kernel. Correct me if I'm wrong.

Dont worry its not the kernel its the player. Apparently it wasnt locking into place right all is well now.

No, I had no cut off either, at all. I've been using this for one more day and I renew my total appreciation for the way it works. Fantastic!

Now, as to the slider bar, I was thinking of something like what papinst showed you, but I admit it is a quite controversial way to look at it. What papinst said makes perfectly sense, as long as you are sitting in the middle of the car, or better of the speakers. Now, this whole thing is needed just because you are NOT sitting in the middle of the car. So, I had this idea, which maybe you like.
Assuming you are sitting in the left seat, you'll hear the "center" of the stereo image shifted to the extreme LEFT, since you are closer to the left speaker. So, when NO ADJUSTMENT has been done, the slider bar should look simply like this (just the bar, no slider, and with the two labels Left Seat and Right Seat, as shown.The reason for this is that the slider overlaps with the exremes themselves. See below why):

L. Seat - R. Seat
||----------|----------||

all bright or all dimmed

Ideally, the two extremes of the bar represent the location of the speakers (let's say the doors of your car). The two half of the bar represent the stereo image as perceived from the two front seats. i.e the left half represents the point of "view" of the person sitting on the left seat, and the right half represents the point of view of the person sitting on the right seat, respectively.

Now, when I delay the LEFT channel, I do so just to move the stereo image further from the speaker I am closer to, in this example the LEFT one. So, supposing I delayed the LEFT speaker a little bit, I would have this

L. Seat - R. Seat
||--+-------|----------||

bright - dimmed

If I decided to delay still the LEFT channel some more, I would have this:

L. Seat - R. Seat
||-------+--|----------||

bright - dimmed

(Notice, I imagine the slider never crossing the middle of the bar if not when sitching to the OTHER (RIGHT) channel delay. See below what I mean*.)



If instead I decided to delay the RIGHT channel, I would see something like:

L. Seat - R. Seat
||----------|-------+--||

dimmed - bright

And if I delayed the RIGHT channel more, I would have

L. Seat - R. Seat
||----------|--+-------||

dimmed - bright

*Also, I noticed that if you keep turning the knob, you move from the LEFT maximum delay to RIGHT maximum delay. This is perfectly meaningful in this graphic UI, since it would consist, graphically, in shifting

from ||--------+-|----------|| to ||----------|-+--------|| , i.e. from the situation in which the person sitting on the left seat perceives the center of the stereo image at his right, to the situation in which the person sitting on the right seat perceives the stereo image on his left.

I hope I was at elast a little bit clear...

What do you think?

I'll see what I can do. It will probably be the last thing I fix. I'm trying to get rid of the glitch first, then the presets, then the slider bar.

I am still having issues with generating and applying patches on my home machine which I am trying to set up for development at the moment.

Of course, this is just an idea, it is great already now!

Ok, if i am sitting in the drivers seat(left side) which side do i want the delay on, the speaker that is closer or farther?Also what does the centimeter measurement for:does it mean that speaker is 3.33cm closer than the other or farther?Or does none of this matter and i just adjust till it sounds good.BTW ive only owned the player for 3 weeks and it keeps getting better all the time MIKE

I would think you delay on the speaker closest to you, because that way the sound (theoretically) arrives to your ears at the same time.

Correct - you want to delay the closest speaker.

So sitting in the left hand side of the car you would want to delay the left hand speaker. The distance is just an approximation of the delay times the speed of sound. i.e. 3.33cm is about how far sound will travel in 0.1ms (I took the speed of sound as 1200km/h).

So e.g. if your right speaker is 1.3m away and your left speaker is 0.3m away you would want to move the left out by about 1m. So you would set the delay to 3.0ms to move the left speaker 1m further away.

Crap... I'm gonna have to break out the ol' Trig book to figure out EXACTLY how long it takes the sound to get from the speakers to the ears, as they're not exactly to the left or right of me but pushed 2 feet to the front..... Now HOW's that go?? Sohcahtoa? I think that sounds right... ;8^)

Or you could just use a tape measure.

"Fix it in hardware"

Damn, that just makes ENTIRELY to much sense for me to think of. Heh... Ya know, just when you think you're doing pretty good, you have a total brain-fart.

Oh, and lest I forget, waaaay cool hack...

Or you could just sit in the usual listening position and adjust it to what sounds best... Saves the extra hardware reworking required by the tape measure method.

Looks like it probably won't be 'til the end of the week before I get another release out. Sorry, I have a real job which is taking a lot of time at the moment and I'm still trying to get a good development environment setup.

Hehe, I can't really tell what it's really supposed to sound like. I can only tell it sounds different.

Basically it should sound like the music is right in front of you. Normally it will sound a like the speaker that is closer is slightly louder. A poor mans version of time alignment is using the balance control.

While I'm here can someone tell me a little more about the patches from Mark Lord. His page says apply the Hijack patch on top of the voladj patch on top of the rdsfake patch on top of the clean kernel. It appears that the hijack patch includes both the voladj and rds fake patches. Can someone confirm this for me? It seems Mark has stepped out of the room for the past few days....

Hmmmm.. Ya know, that's true... To get it exactly right, you need to time-delay the closer speaker, AND reduce it's volume a hair to match the volume hitting your ear from the other speaker. Sorry for stating the obvious, but I just never really thought about it.

Actually depending on where you are versus the speaker, off axis or on, you may not want to change the volume. Like was mentioned, you can't science this out. Just play with it until it sounds good. A "pink noise" track or a good song with a single vocalist is ususally the easiest way for me to set something like this up.

Shonky, thank you SO MUCH for starting on this!

I downloaded a whole bunch of free sounds from somewhere, don't really remember where. I put them all on a web page Here.

Here is what is on the page.

Pink Noise - In phase

Pink Noise - Out of phase

Sirrus Tone - In phase

Sirrus Tone - Out of phase

White Noise

Sweep Left

Sweep Right

Cool effect from the end of the Aphex Twin song Windowlicker (looks awesome in Windowshade or Spectrolog visual modes)

The in and Out Of phase sounds are good if you want to see if you wired your speakers the correct way.

BTW Tony, RE: "fix it in hardware". That's hillarious, I was rolling.

Ah, good. Wasn't sure if anyone caught that joke, thanks. I've actually used it before (in similar situations), never got any comments until now.

haha, i used to call my "production group" in college Fix It In Post Productions.

Is it also possible to have a config.ini setup for the Delay.

We could give only 2 lines 1 for the left and 1 for the right :


right=183.2 (in cm)
left=0

And the prog will autocalculate the delay with the distance.
Eventually have a config fot home and one for car.
Yes I need also to setup delay for home ...

Hi Christian, any chance you'll get a kernel patch out soon?

The link is dead. Can email me this so I can implement it into my player?
Dave

I'm definitely getting channel cut out problems. Meaning a channel would have no sound coming out at all.

I've had one lock up occur by spinning the knob very, very fast, the empeg locks up completely and needs to be yanked to fix.

Also, I might be crazy, but the Left and Right are backwards?????? I've tried delaying it to the left -- left hand drive -- and it sounds like ass. Then I delayed it to the right and it sounds centered (???). The build in left/right balance works correctly. But sure what's happening exactly. I will do more testing later.

Calvin

Is the distance values the distance of the delay from the delayed speaker to your ear or the distance the focal position is moved relative to center? I suspect it is the former... but the GUI has me thinking that it is the latter.

Calvin

Yes it appears the server hosting our website has gone out to lunch. I have emailed you a copy Dave. In the meantime can someone else host it for me? Mark Lord appears to have disappeared for a while otherwise I could have it hosted there.

I don't really have time to do a sourceforge site at the moment. I'm struggling for time to add the extra features people want and investigate these bugs. I will try and get some things done today. I am having the day off today, so I'll see what I can get done.

(edit)
Link appears to be working now...

Okay then eternalsun,

acurasquirrel says that his channel cutout problem was due to the sled not being in properly. It appears he (she?) may have been wrong with their diagnosis. I will see if I can reproduce it. Can anyone else?

The distance is the distance the channel is moved away. So if the speaker is 0.3m away physically a delay of 1.0m will put the speaker 1.3m away acoustically.

I don't know if this helps, but since it is working perfectly here I thought I could share what I did.
Without delay, I always heard the left channel louder and "closer" to me, so that the supposedly "centered" singer's voice would sund slightly on my left, and the whole stereo image was distorted towards my left.
SO, I started to delay the left channel (acoustically pushing it away from my position by the amt of cm. indicated on the display) until I clearly heard the singer's voice right in front of me (I did not measure anything, I just closed my eyes to figure out it all better). When I reached this status I could hear the whole stereo image much more clearly. Everything sounds better now, noticeably!

Darn... down again (9:50pm pst 2/18/02)

Ditto on the copy via email if possible.

<<<<pleeeeaaasseeee>>>>

TIA

Bugger is there anyone who can host it for me? Mark Lord is out of action it seems otherwise that would be an ideal place...
