Yes I agree synthesizing is the future and technology to simulate very complex sound from scratch has been here for quite some time. It's called physical modeling

Forget about piano, for example! Limiting factor is huge DSP processing power needed for this technique to sound anywhere near the sound of multi sampled instrument

In the mean time the only reasonable and DSP cheap alternative is multisampling real engine and crossfading between samples. Yes, it's compromise ... but the results are much better at the moment with this technique.

You're pretty much right, but you can't really compare multi-sampled instruments to car engines since, for example, a piano sample bank will contain samples of every single key, probably even multiple times over for different strength and techniques, whereas a sampled car engine currently contains about 10 samples, where of course all sounds the engine produces are mixed together. Sort of like a piano bank with 10 prerecorded chords suitable for progressing from one to the next.

The quality and useability of sampled instrument banks comes from sampling an enormous amount of source, "standard" multi-sampled car engine banks is nowhere near this sort of thing.

Note: i'm not saying LFS' internal sound engine sounds more like real engines.

I've managed this many times, there's no relation to hardware, it's as simple as ...

Quote from traxxion :

causing the LFS window to loose focus while starting up

I usually alt-tab twice and hit shift-f4 hoping for LFS to go into windowed mode, if it doesn't, repeat. It's not really an LFS bug, although it would be really nice if two sanity checks related to this could be added:

• If LFS does not receive any input for x amount of time while being at the entry screen just after launch, go to windowed mode.
  
• If LFS at launch detects another instance running (Warning - another instance of LFS is running .. ), go to windowed mode.
  

I've actually managed to start a second instance of LFS with the first one being in fullscreen, this loosing-focus annoyance occured and getting things back to normal became twice as tricky.

Quote from DratsaB :

I want to try and make some sound sets and have found some sounds from a game I think would suit a car in LFS. Trouble is, those pesky programmers put the sound files in some form of compressed .bzf file. Anyone have any idea how I might go about acessing its contents?

Google found this for me, i've no idea what it is.

Quote from DoriKiN :

Its like forbiden to compress video sourece before editing. U loose like 50%of your original quality.

Wrong, there are many ways to compress video, and of course lossless compression results in no quality loss.

Really nice

Quote from WolleT :

No, LFS is playing the replay everytime in the same speed. It doesn't matter how many cars are on the track. The replay data will always played in the same speed.

Isn't this the problem itself?

If a broadcasters LFS does not write to the temporary mpr for some time, no data can be sent to clients until it does (unless you manage to grab mpr data from memory / internal buffer). LFS still buffers and plays the replay at the same speed, meaning that if there was no data sent for some time, a replay can reach 'the end'.

Setting a bitrate wouldn't solve this, but the relay could broadcast a pause / unpause for clients to send thru insim, pausing playback if data flow is too low.

How can I repair this?

Does the sessions directory exist?
Are permissions set so the webserver/php can read/write?

open( ... /lfsoliv76/sessions/ ) No such file or directory (2)

Visit http://www.lfsforum.net/search.php, pick 'Search Titles Only' and enter 'unlocks' as search keyword and you'll find the answer(s) to your query.

Quote from BulliT :

what to do and what not to do with directsound.

Maybe you (Scawen) could try getting in touch with some DirectX/DirectSound software synthesizer developer, the general approach to buffers etc while working with realtime generated sound can't really be a secret.

U22, I can get some very slight crackling in the BF1 at south city but I need to turn the volume up so much it's hard to tell if it's caused by LFS or if it's just distorsion. In a replay with ~17 GTR's on the grid i got some cracks/pops. Still hear steps in engine sound, they're smaller but still very audible, specially in the XFG. Don't know if steps is the right word for it so i made examples, these are very exaggerated, LFS sound isn't this bad.

All U22 tests with sound blocks at 1, there's no lag or delay, just these steps in sound. Delay/lag at 5 blocks is extreme. I run U20 with sound lag at 0.15s.

XP, 3 GHz Celeron, Realtek AC97 WDM Drivers rev.3.93.

Works great , feature request would be some options for button combinations, i'd like to 'lock' the view in its current position by pressing both buttons, then return to center on release.

You would probably use a mix of the command line parameters (docs/Commands.txt), basically write batch files or create a new lfs://-protocol handling application with support for the password being part of the link.

Quote from duke_toaster :

People have to have Join2LFS installed. Put a link to a specific thingy like

lfs://|ServerName|0|S2|/

What the 0 means is beyond me tho.

The zero is a password flag, 1 flags the server as passworded and makes join2lfs display the text 'caution: server is password-protected', while 0 does not.

U21, audible steps and/or odd interpolated steps in engine sound, U20 brings back normal (better) sound. Seems completely unrelated to hardware / DirectX sound acceleration. Latest drivers made no difference.

3 GHz, Windows XP, Realtek AC97/WDM (VIA).

(horns work. )

Samples are stretched to twice their original length.

I have no chance to get the car name before the first lap (if I have no IS_NLP package at beginning) cause in the mci packet for example there is no start position / plynumber but I need the playernumber to request the IS_NPL package.

You can request all NCN's

And all NPL's

Quote from OldBloke :

Am I missing something?

Looks like you're using the version Dygear links to in the first post, if so, try the most recent one instead.

PHP4 issue again, updated and hopefully works now.

http://prdownloads.sourceforge ... -cvs20061005.zip?download

So you're looking for a feature which the profiler obviously does offer but you'd rather not use the profiler because of system load?

On my rather slow and old system, the profiler has currently wasted:

• 0.006% cpu time.
  
• 0.2% memory.
  

For something you're actually using, i'd say this amount of resource use is quite reasonable.

Edit: Item 3 in your list isn't correct, the profiler applies profiles based on which program is active, not based on how you start it.

parse error, unexpected T_NEW ...

If you're looking for assistance you'll need to make the source visible, that error message says pretty much nothing.

Rename the file to .txt or make another script containing ..

Quote from traxxion :

error?

You're probably running php 4, which fails at declaring variables as private (php5+). This code doesn't really need php 5 and i think Dygear will remove the php 5 specifics.

Quote from ORION :

I'd rather open 3dsmax on a machine and (try to) modify the material texture camera position and execute the render using maxscript.

Quote from ramtech :

those renders quality is shitty.. so whats the point? id rather do it on my box using vray or something

The point is probably that if this little renderer would support textures, you could render small team car pictures on your linux box without a desktop environment, without going outside php and even without writing any files if you wanted to. There are probably much better ways of accomplishing this, but i don't think launching a full-featured 3d modeling / rendering application would be an option for the kind of thing Dygear has in mind.

Very nice stunt.

I think the suspension damage would be enough to gradually remove that advantage throughout the rest of the lap, and i very much doubt anyone would attempt to recreate that stunt while going for a new wr.

Quote from z3r0c00l :

Someone should run a server where inSim pits you and the other car instantly on contact - it must be possible, as the training sets can detect contact with another car and fail you for it.

Handling of car positions in multiplayer is much harder then handling them locally, currently you'd need to guesstimate contact by comparing distance, heading, etc, there is no packet for "contact". Even with a very good formula, the maximum settings of 6 pps as i understand it means the remote cars are in their correct positions during only 6% of physics updates, meaning there are 94 updates where positions are interpolated more or less accurately. Add lag issues and it's not a very tempting project.

A modular / plugin-driven "general purpose" insim daemon written in reasonably object-oriented php 5.

Features include a content distribution/update system, a sloppy GTK config editor and hopefully a good set of plugins and documentation.
