Hi,

I managed to put 894 MB of music on a CD-R 99 Min.

Playing it this morning in my new Ford (DENSO Navigation System) car player, which supports mp3, I noticed two problems:

1) Bass is too rich, often it brings to extreme distortion
2) Often, music skips

I had the same behaviour while I was testing on CD-RW, but I wanted to try a CD-R before reporting it.

The recording source were original CDs, I used EAC and Lame 3.97b1 to convert into mp3.

Command line:
-V 2 --vbr-new --add-id3v2 --pad-id3v2 --ta "%a" --tt "%t" --tl "%g" --ty "%y" --tn "%n" %s %d

I passed everyting into mp3Gain, 90db album track gain.

I'm gonna try my standalone DVD Player and see whether the issue might just be a low quality of my car player.
Maybe an issue in reading VBR encoding??

In the meantime, should you have any other suggestion, it is very welcome.

Cheers
Alex

I find that stripping out all tag info (make a copy of your songs before you do this) makes them play much better in my Ford car audio system. For whatever reason, tags really mess up play.

You mean that you just use -V 2 --vbr-new and get better sound?

Alex

Hi,

To follow up my previous post, the CD Data mp3 doesn't skip when played into my home standalone DVD Player, it's a good player and in a way I did expect this.

However, something is wrong with the encoding because the high frequencies definitely tend to hiss.

In the car player, I have the same problem but more marked and in addition when there's a peak in the track, it skips.

This is a mistery to me, unless what ezra2323 states is true, but I would be even more perplexed

Thanks
Alex

Try seeing if you get the same results when encoding at the CBR 224kbps and ABR 224kbps. Some car CD decks have hard times playing VBR mp3's eventhough they are compatible with the mp3 format. Try doing a CBR mp3 then try doing a ABR mp3 and see if you get the same results.

I have used --alt-preset standard for Lame 3.90.3 and now have switched to -V 2 --vbr-new for Lame 3.97b1. I have not had any problems with the newer or older mp3's that I encode.

I would also try tacking off the tagging commands and just let EAC do the tagging. I have always done this and have yet to run across a problematic track in my car CD deck.

Just some things for you to think about.

Edit: changed --vbr-nre to --vbr-new, bad spelling.

I guess you meant -V 2 --vbr-new, did you?

Thanks for your suggestions, I'll prepare a test disc now and try tomorrow morning.

I'll come back with results.

Cheers
Alex

I think your deck may just not like the 99 min cdr.

While that could possibly explain skipping (smaller and tighter pits/lands) it shouldn't have any effect on the bass response....

I followed the suggestions of kornchild2002 and as promised, here's the outcome:

I encoded in VBR -V 2 --vbr-new, tacking off the tagging commands and just let EAC do the tagging.

Result: Perfect CD, no skips, no hiss, no bass problems anymore.

I also, tested ABR and CBR 224, no problem at all, it sounds good.

So, my conclusion is that when letting LAME do the tagging, somewhere it messes it up.

This was also the expereince of ezra2323 in his post above.

Is anybody able to provide a logical explanation to this or is it a bug in 3.97b1?

As I said in my first post, I had the same issue with a CD-RW 74 min., the CD 99 has nothing to do with the problem.

Thanks for your comments
Alex

Well, apologies if my comment seemed ignorant of what you had already stated. Here's what I read:
Not sure where I was supposed to infer the capacity of your CD-RW, but not important enough to argue over.

maybe the car player doesn't understand id3v2 in the version used by LAME?

Robert,

I woould exclude that because the sound is bad in the home standalone DVD Player, which is a Hi-End one.

I guess is something technical, that's why I wanted to hear the opinion of a developer

Thanks
Alex

Just to satisfy my morbid curiosity... Try a good band CDR and see what happens.

i'd try -V 2 --vbr-new --id3v1-only --ta "%a" --tt "%t" --tl "%g" --ty "%y" --tn "%n" %s %d

maybe they would do better with just id3v1.

Well, my Pioneer DVD player doesn't understand id3v2 tags, id3v1 only.

Did you mp3gain in your successful test above too?

Hi guys,

I started again my encoding and at this point I'm lost.

Reading about the configuration of Compression Options, I had undestood that if you use a LAME command line, the bit rate windows doesn't really matter what you put in because it has no influence when the command line is there.


So, I set up -V 2 --vbr-new and in the Bit rate window, I choose 320 kBit/s.

Look what happens when compressing to mp3:

Then, I set up -V 2 --vbr-new and in the Bit rate window, I choose VBR 192 kBit/s

Look what happens when compressing to mp3:

At this point, I don't know what to say more, but the question is the following:

1) Either I have seriously misunderstood what I've read so far

2) Or there must be an important part that I've missed.

Whoever has an explanation, is very very welcomed!

Thank you!
Alex

my opinion is that we should stick with figuring out how to get lame's internal tagging routines working correctly w/ your player. from what i understand, eac's tagging routines are inconsistent. i still would be curious to see how things turned out if you stick to just lame's id3v1 tags (using -V 2 --vbr-new --id3v1-only --ta "%a" --tt "%t" --tl "%g" --ty "%y" --tn "%n" %s %d).

I can try and let you know...tomorrow, I'm in Europe.

Cheers
Alex

Hi,

Can anybody confirm me if

-V 2 --vbr-new and VBR 192 kBit/s in the Bit rate window

is the right behaviour and

-V 2 --vbr-new and 320 kBit/s in the Bit rate window

is the wrong one?

Thank you
Alex

I think you should set 'User Defined Encoder' in the Parameter passing scheme setting rather than 'LAME MP3 Encoder'.
This way, the bitrate drop down list won't override whatever you fill in the 'Additional command line options'.

Read this Wiki entry.
It tells you how to set EAC to work w/ LAME properly.

If I set 'User Defined Encoder' , when i compress I get the following error:

The external compressor returned an error!
Options: -V2 --vbr-new
File: M: etc.

I don't know why.

Any idea?

Alex

I took the time to read it, but could not find any explanation on the meaning of %s and %d, which I'm sure is evident to this community but not to me given that I cannot find an explanation of their meaning.

Thank you for pointing me to the solution.

They define the source and output files.

Thank you Acid.

ok, i'll add something to the guide to explain %s %d
