You can see the full command-line generated by LameXP in the log. Or just inspect the LAME process with a proper taskmanager.

But I don't test explicitly with old LAME versions (especially not with one that is more than 4 years old), only with the up-to-date one that is included in LameXP. So, no guarantees Any particular reason why you want to use such an outdated LAME version? Quote:
But you may wish to actually compare the command-lines in order to make sure you hadn't set any extra options in LameXP...

I think I got mixed up with something else. LameXP is using it's own internal Lame mp3 encoder? I see that it copies a bunch of files to a sub-folder in the temp directory. The version that is there is 3.99 release 5, 469KB. Version 3.98.4 was the version I was testing and comparing the result using the CMD prompt. I assume it's not possible to override the version LameXP is using? 3.98.4 was a bit of a cult version, in terms of sound quality, many seem to prefer to more recent versions. I did a test of 3.99.5 in foobar2000 compared to 3.98.4 and the newer version sounded poor in comparison. (although once again, I'm not sure what arguments are being passed to the encoder) At least in the LameXP log, I can see what its doing. Thanks for that tip. |

http://lamexp.sourceforge.net/doc/FAQ.html#3d6684e9 Is there any serious listening test that substantiates this theory?

is "transparent" (What ever that means). I think some of it depends on the material; This afternoon I took 5 or 6 uncompressed WAV files of different kinds of music and encoded some mp3's at the command line using 3.98.4 and 3.99.5 using v1, v2 & v5 all with the -h switch. To me neither of them sounds like the WAV file. The uncompressed music just has more "presence" that the mp3's aren't quite able to reach. I can hear in some of the samples that v1 sounds better than v2. The point is, for playing in the car, even a playlist on your favorite media player over the computer speakers, the default settings are mostly good enough. HD audio sounds better than CD @ 44.1 khZ 16 bits, but does that mean you can never enjoy your CD's again, because in the back of your mind you know there's something better. I hope not! Some music sounds better on vinyl. The one that I notice the most is Carole Kings Tapestry. I even have an audio cassette that was recorded on a hifi from vinyl that retains the warmth of the vinyl, and to my ears, sounds better than the CD, even the remastered version from a few years ago. I like your program, I'll use it as is, no need to substitute a different Lame. It's been some years since I used it, so long I actually forgot about it. I maintain a folder for these "portable" apps, and right next to this one, I was surprised to see Lame XP .2008 12-24 version 3.07. so it's been a while since I looked at it. Thanks again. |

It means whether or not you can hear a difference between the original and converted file.
If you cannot hear a difference, it is transparent. More here: https://en.wikipedia.org/wiki/Transp...compression%29 |

taken into account? I know that when I converted some of my video to mpeg-2 DVD, the audio (different types) was converted to ac3-2-channel. I found 256 kbps ac3 was at the point where this kind of conversion sounded "transparent" - in contrast 224 kbps ac3 sounded a little "pinched". But this is not music. It's a typical video, some voices, some environmental sounds, etc,etc. I think what I'm trying to say is that when we listen to music we listen with a much more critical ear. Especially when we convert them ourselves. Through my local library, they have a thing where you can download 5 free music tracks a week. I've downloaded some and so far I've seen 192 and 256 kbps mp3. Not having a better source to immediately compare to, and the fact that they came from the library and were free, gives me a psychological "freedom" to enjoy them as-is with out worrying about the sound quality. |

Anyway, LameXP is just a fron-end and uses the official FLAC encoder by Xiph.org (currently version 1.3.0, which should be the latest). So, unless you think that LameXP is calling the FLAC encoder with the "wrong" arguments, that's probably something you'd have to discuss with the FLAC developers. And if you do think LameXP should be calling FLAC in a different way, then please be more specific. I cannot see anything related to "tag HDCD" in the FLAC help screen...

In that case, don't bother. I've made for someone mkv file with flac from 24 bits wave for audio, encoded with LameXP.
The feedback was : - Encode is not clean, because there is "Encoded with LameXP" in the comment tag... I've been stunned by this stupid comment ! - The bit (or tag, don't know) HDCD is set to 0. 1 should had been better. If it's something you don't know about, never mind. |

If you don't like it, you can clear the comment field at any time or simply input your own comment text there. See the "Meta Data" tab. Of course it also should be straight forward to edit or remove the meta tags of an existing FLAC file. (Despite of its name, Mp3tag is capable of editing FLAC tags) Quote:
And is FLAC supposed to add this automatically or is the front-end supposed to add it explicitly? In the latter case: Under what circumstances? Well, at this point it's not even clear whether this so-called "HDCD tag" is a bit in the FLAC header or just a custom meta tag...

Maybe i was not clear enough. This was the feedback from the person for who i made the mkv.
As i've stated, i found this comment nonsense. But thanks for the tips for removing it. I personnaly use and will still use your tool, i found it very usefull. Thank for it. Edit : Ok, a little more information from "the complainer" : Encoded with LameXP : Code:

jpsdr,
Out of interest, what application was used to back-up the HDCD? I'm not aware of any audio CD back-up application that's able to make use of the HDCD flag even when creating PCM file back-up's!

Absolutely none, it's just a 24 bit audio wave file extracted from a Blu-Ray m2ts. It's not from CD audio, and i don't know any application able to do it, and i didn't even know about HDCD 2 days ago...
I was just complained to about the fact i described, and so warned that LameXP may be less reliable because unable to handle this feature, but eac3to can... It seems that "this HDCD" may be used on other files/tracks than on CD. I don't know, and don't want to bother Lord Mulder too much if he also doesn't know about it. |

HDCD is modern ADPCM: Give more bits to soft sounds and less to loud sounds. The HDCD tag just tells the player (only dbPowerAmp understands it) to uncompress it back in 24bit when playing, otherwise it sounds much too loud. Your friend is definitely spouting nonsense if he wants the tag added, but he can add it himself if he wants, it's just a plain old tag.
