Thanks for the update...roll on the Final
I like using AAC encoding - it's just a shame that my iPod and Sony mp3 players don't "support the sound quality" of the lower bitrates (e.g. 32kbps or 64kbps) - they sound rather crisp on the computer, but the high-end is lacking on the mp3 players (it's similar to listening to mp3pro encodes on a software player which doesn't support mp3pro playback).

HE-AAC is nothing but (LC-)AAC combined with SBR (Spectral Band Replication), the same way "mp3PRO" is just good old MP3 with SBR pre-/postprocessing. Any player that supports LC-AAC can decode HE-AAC as well. But without a fully HE-capable decoder you only get half the sample rate for 'HE' files (e.g. 22.05 Hz instead of 44.1 Hz). As a result the "higher" frequencies are missing completely when playing HE-AAC files with a LC-AAC player/decoder, giving it a rather "dull" sound... (Note: HE-AAC is only used for ultra-low bitrates, which explains why you won't get those problems at higher bitrates. At higher bitrates plain LC-AAC will be used)

Plus, you could also remind them there's such a thing as AAC-HE PS too!

All my Mediatek chip-set based hardware players fully support playback of AAC-LC, AAC-HE and AAC-HE PS sources

Thanks LoRd_MuldeR
I have few questions plzz help, I want to compress heavily an audio(with 32kbps, 6 channel to 2 channel) .....so Is it good to enable volume normalization if yes what setting should i use now the defaults value are Peak Volume(dB)= -0.50 Equalization Mode= Peak Level Can i hide dropBox? |

WARNING: People tend to rate the quality of audio higher when it's "louder". So be sure that you don't get fooled here Consequently, if you want to test the effect of normalization, you should compare the following: (1) Compress -> Normalize -> Decompress/Listen (2) Normalize -> Compress -> Decompress/Listen Sure. Right-click.

Issues with Final 1
I am testing LameXp v4.03 Final-1 Build 764 this AM.
Today I processed some mp3 files containing cover art into a new directory with this build. I lost the cover art in the new folder I am reencoding with LAME -- the input files are 48k CBR mp3, and the output is VBR 9 at 16k sampling frequency. The encoding went ok, but the cover art is now gone. Your release notes say this is supposed to work. This is issue #1. Also I was unable to select 8 as my minimum bitrate in LAME having instead to supply -b 8 using the Lame cmdline options. Is there a reason for that or is this an oversight? Furthermore, when I attempted to drop my audiobooks folder on LameXP's main window, it said 1 file not recognized. I had to enter that directory and select all its subfolders to drag and drop. The source was a folder on my Desktop. So when I processed, all files were created in a flat output folder losing the original directory structure. Now when I select "prepend directory structure" it creates users/owner/Desktop/NWT.cbr/subfolders/files within the output folder which is better than having them altogether but I guess I do not know how to control where the files are generated. This is the least important issue as I can always prune the folder and rename at a higher level. I'm not sure if this is an issue or I just dont know how it is supposed to work. Othniel |

I have more information about my previous report.
Windows Explorer is stupid. ok you knew that already. Well Final-1 Build does include artwork. Mp3tag shows it, MPC can play my VBR mp3s. But WMP will not handle my VBR mp3 files and Windows Explorer will not show the embedded artwork. I was not aware of how frail and wimpy WMP is as I primarily use MPC. Please excuse the false alarm. I hope to make it up to you in working on the Linux release of LameXP. |

Then report the FALSE POSITIVE to the developer of your AntiVirus software. And, if they don't fix the problem, switch to a better product. (I can't do anything about the issue, because it is impossible to know what aspect of LAME triggers the failure in their software)

However LameXP will not deal with cover art that is saved as a separate JPEG file or in any other way. Please use Mp3Tag to make sure your input MP3 files contain cover art. Then, after the files have been re-encoded, check the output files again. Quote:
Note: The lowest supported bitrate in original MP3 (as defined by MPEG-1) is 32 kbps. MPEG-2 added even lower bitrates to MP3, but only for 16, 22.05 and 24 kHz! See also: http://lame.cvs.sourceforge.net/view...switchs.html#b Quote:
I guess there was something like "thumbs.db" or "desktop.ini" in your folder. Maybe you didn't see the file, because it was hidden. LameXP will reject those, of course. (I should make LameXP ignore files like "thumbs.db" or "desktop.ini" in a future version though) Quote:
Let's assume your output folder is selected as: C:\Some Output Folder Also let's assume you are converting the following source files: C:\My Music\1st Artist\Song 1.mp3 C:\My Music\2nd Artist\Song 2.mp3 D:\Foobar\Test\Rnd32\Whatever.mp3 Normally LameXP would create these output files: C:\Some Output Folder\Song 1.mp3 C:\Some Output Folder\Song 2.mp3 C:\Some Output Folder\Whatever.mp3 With "prepend relative source file path to output file" enabled, you will get these instead: C:\Some Output Folder\My Music\1st Artist\Song 1.mp3 C:\Some Output Folder\My Music\2nd Artist\Song 2.mp3 C:\Some Output Folder\Foobar\Test\Rnd32\Whatever.mp3

MP3 Voice --vbr-new
>>The values were limited to a "sane" range. Why do you want to force LAME to use such ultra-low bitrates?
I am a Linux cmd line kinda guy. LameXP GUI is new to me. Here is my "NORMAL" command line to process voice recordings: lame --resample 11 -b 8 -V 9 -a FM103-3_102911_003.wav Sometimes I include the --preset voice switch -- mostly not. I work with voice recordings transmitted over FM. For VBR to work right -- you must let LAME decide the appropriate bit rate. -b specifies the minimum and -B the maximum. 32 is the default for -b so VBR cant take advantage of 24, 16 and 8 encodings unless you enable this via switch.
