Hi I'm going to buy a car mp3 cd player. I'm searching for a setting thats slightly better in quality than what car audio can be... I've got only 2 10"-loudspeakers in the back of the car, nothing special.

I guess alt preset fast standard is way too good.

The speed of calculating the files should be as slow as possible.

--alt-preset 128

Trust me, if you can hear any difference between a 128kbit ABR encoded MP3 and the original CD in a noisy environment as a car, then your hearing is exeptionally good. Infact, it's most likely so good that --alt-preset insane probably wouldn't prove sufficiant for you in a quiet environment...

could save some space cause in noisy environment, intensity stereo should be good enough






How about ?



or



Can fit more files

What are these options (-m f) doing? I think for car environsments we can cut some frequencies, which? (It'll be an average car radio ~250$)

Hey, I tested the second (112 mf) its not much faster than --aps on my machine! Aps works @ 1.0play/cpu, this one works @ 1.2play/cpu...

About that --alt preset 128, I can detect several MP3s in such a noisy environment.
(ABXed with burned CD-RW (4 samples x 8 tries - all hit - total time: ~20 min - engine was running)
ap128 fails on electronic music, unless you use something like --lowpass 14,
which sounds rather bad for me)
I'd rather recommend --alt-preset 160 -m j if you have enough space.
Or even --alt-preset standard -Y

-m f forces joint stereo on all frames... this can hurt some samples.
(My testing was done with only --alt-preset 128)

I do not have highend equipment in the car.

why don't you try the medium presets in LAME 3.93.1

Beware of clicks and pops at the end of the track when encoding with Lame 3.93.1. That's been my experience when I play the files through a hardware MP3 player. I only use Dibrom's 3.90.2 and I have no problems.

Personally, for car audio I'd either use --alt-preset CBR 192 or --alt-preset CBR 160. I think they'll encode faster than any "equivalent" VBR/ABR setting and the music will sound just fine. You could also avoid the possibility that the player doesn't handle VBR properly.

all depends how loud you actually play it and how good your speakers are...I still need --aps in my setup.

--aps fast standard seems to sound fine and encodes at a good speed here (apfs: 1.75 CPU/ aps: 1.0 CPU)

I'd stick with --APS; its likely that you'll be playing the MP3 discs elsewhere as well at some point anyway

It also depends on whether you ever keep listening after you've parked, or if highway speed
with studded snow tires is the environment you're tuning to.

Either way, with speakers in the rear (especially, but pretty much also with any car install)
you can kiss off considerations of "accurate sound stage", or worrying about life over 16 khz.

actually, you'd be surprised what you can do, depending on layout of vehicle. My '90 Cavalier has an uncluttered-enough dash/cabin layout that I happened to be able to get awesome unobstructed angles using kick-panel speakers for the front stage. Paths for both speakers to both listeners are not blocked. You would have to hear it to believe it, it's got an incredible soundstage. The speakers in these pictures are actually the old Blaupunkt 6.5" speakers that I had in there for a month or so while I squirrelled away enough to get Infinity Kappa series speakers to match the ones I already had in the rear. The midbass driver is aimed at the opposite passenger, and the tweeter in them is at an offset angle so it's pointed more or less to the opposite shoulder of the nearest passenger. End result is that both speakers are about as far away from you as possible, thereby greatly reducing the path-length differences and greatly improving the soundstage. And with the offset-angled tweeters you hear both sides very clearly, nowhere near as much 'onesidedness' as you usually get in a car. The rears are a bit quieter than the fronts so they don't smear the image as much as they usually might, they're only to provide what's usually referred to as 'rear fill.' So what I have at all four corners now are Infinity Kappa 6.5" two-ways, pair of 15" Kicker CompVR subs in seperate sealed enclosures (well, one BIG box divided down the middle to isolate them from each other), Clarion APX-401.4 4x50rms@4ohm amp for the Infinitys getting everything from ~110Hz and above, APX-401.2 2x100rms@4ohm for the subs, which is actually running at 2ohms and 200watts rms since each sub has dual 4ohm voice coils running in parallel and handles everything from 80Hz and below. Here's some pics so you can see what I mean about the fronts. And of course there's the JVC KD-SH99 to feed it all.

<edit> and oh yes, 16KHz and above is most definitely there.
