LAME is a MP3 encoder and the Lame ACM MP3 is an ACM codec that you can use in most applications for example in Virtualdub(to install the ACM codec just extract all files and right click on the LameACM.inf and select Install). LameDropXPd is a practical frontend for LAME that makes things easier to the user, as there is no need to know about command line usage: most LAME settings are reachable on a graphical interface.

Just because the patent has long expired and Fraunhofer says it is dead- because it can't make anymore money out if it-doesnt mean that mp3 wont be around for decades to come! Aac is better in the sense of being a more modern efficient codec, but it is noisy and prone to artifacting like introducing hiss or clicks. I've proved this to myself time and time again when checking ripped files to aac and running them through Magic Audio Cleaning Lab. Mp3 most of the time is better acoustically tuned to avoid these problems. He-aac is superb but that too is prone to loads of artifacts like hiss, clicking etc.

A good tip is to rip to wave or encode to wave whatever you do, then check it through some spectral analysis tool like Audicity or one I mention above-Magix(recode to remove any found artifacts if any?), and then drop all your wavs in LameDropbox. Check in mp3Gain for clipping later.

Mp3 will be around for decades to come. All this nonsense about FLAC sounding better is pure placebo effect, as 95% of the population older than 15 will struggle to hear frequencies higher than 16khz. Encoding to flax is just a waste of time. Lame 192kbps abr or if you must 224kbps abr is more than enough for quality!

Review by Sara on Feb 9, 2020 Version: OS: Windows 10 64-bit Ease of use: 10/10 Functionality: 10/10 Value for money: 10/10 Overall: 10/10

The changelog reflects the hard work of Lame developers, but if you look at the bug fixes as in 3.99.5 they appear to be introductions after previous build recompiles and moreover fixes to things most of us in the non tech world have absolutely no idea about. Just look at some additions to the code i.e feature requests or workarounds!

These bugs 99.99% of the time reoccurring have little effect on converting that wav to mp3. This latest build is superb and bug free. My previous other is Like others have stated 3.99.5 stable is not on top of my list of to use frequently versions, as I did not like the acoustic tuning and the stereo separation always seemed flat and dull to me. Not so with new version. So thanks for that.

Tough call to make which is best version of Lame. It much depends on the software you use and how stable that version of Lame is as in a cd ripper or the settings you use. I've had great results with versions 3.98, 3.99.25 at lower bitrates due to some great tuning of the code, but some might prefer just the 3.98.4 version.

I don't like 3.99.5 version at all for many reasons. The changelog of Lame reflects bugs which are rarely seen by most users, so any version is pretty stable in my book. The 3.100 is a great build!

Review by Allan on Dec 10, 2019 Version: 3.100 latest revision OS: Windows 7 64-bit Ease of use: 10/10 Functionality: 10/10 Value for money: 10/10 Overall: 10/10

This version of Lame keeps the higher frequencies at lower bitrates than all other versions I used. At 160kbps vbr the frequency is just over 17khz and near transparent for me. Other versions in most converters/gui's always do the cut off at 16khz or so and not much over for higher bitrates up to 256kbps. Very pleasing build of Lame, best yet! Also at this bitrate and above the tuning has no noise/hiss artifacting which I almost always saw in build 3.99.5 using similar bitrates.

Review by Karol on Dec 5, 2019 Version: 3.100.21 OS: Windows 7 Ease of use: 10/10 Functionality: 10/10 Value for money: 10/10 Overall: 10/10

Lame is a 10/10 project but the versions hosted here are very weird. I downloaded the 32 bit for XP and it was totally rejected and cannot be installed/registered in the system using right click, but some converters I use.

Also the 64bit does not work on the right click as stated in other reviews.
I searched the Net got myself another 32bit version of the 3.100 and dropped it into Audiograbber 1.83. Works like a dream baby! You can get either 32bit or 64bit versions below.
