You can use the LAME executable with RazorLAME interface or you can use the DLL with another software (AudioGrabber, CDEx etc). I prefer the combination CDEx or AudioGrabber + LAME DLL. In the archive are included both: exe and DLL.

Features:

• Many improvements in quality in speed over ISO reference software.
• MPEG1,2 and 2.5 layer III encoding.
• CBR (constant bitrate) and two types of variable bitrate, VBR and ABR.
• Encoding engine can be compiled as a shared library (Linux/UNIX), DLL or ACM codec (Windows).
• Free format encoding and decoding
• GPSYCHO: a GPL´d psycho acoustic and noise shaping model.
• Powerfull and easy to use presets.
• Quality is comparable to FhG encoding engines and substantially better than most other encoders.
• Fast! Encodes faster than real time on a PII 266 at highest quality mode.
• MP3x: a GTK/X-Window MP3 frame analyzer for both .mp3 and unencoded audio files.

What's New in version 3.98.2:

• build system related: some fixes for mp3rtp and abx tools
• encoder padding values were not correct when resampling was involved
• frequency filtering API was broken; in case you want to use your own higher quality filtering method, it is now possible again to disable LAME buildin filters
• ID3 tagging:
  • id3v1-only switch did not work anymore, fixed
  • tg improved, now it matches more often one of the ID3v1 genres, even when small spelling errors are involved
  • add-id3v2-size is a new switch, it allows to define your own padding of n bytes.
