Codec : LAME MP3 Encoder 3.98 alpha 11


LAME MP3 Encoder is the best mp3 encoder and is available for free! LAME originally stood for LAME A in't an M p3 E ncoder. LAME is an educational tool to be used for learning about MP3 encoding.

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

Features of LAME MP3 Encoder :

- 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.

LAME MP3 Encoder 3.98 includes :

- lame.exe, lame_enc.dll (ICL4.5) and lameACM.acm (MSVC6)

Changes in LAME MP3 Encoder 3.98 alpha 11:

• Alexander Leidinger:
- Add TLEN (ID3v2) support (Submitted by: Linus Walleij).
- Add number of total tracks per album (ID3v2) support (Submitted by: Kyle VanderBeek).
- Some seatbelts for overflowing arrays in the ID3v2 support.
- Update the RPM spec (Submitted by: Kyle VanderBeek).
- Fix some mem-leaks in the error case.
- Update to newer autotools versions.
- Update to use a recent libsndfile (submitted by libsndfile author).
- Intrinsics support enabled for gcc
• Robert Hegemann:
- The newer VBR code is now LAME's default VBR routine
- Fixed: in case of not enough bits the new vbr code incorrectly used old vbr routine
- Improved ATH adjustment in low volume cases
- Fixed (PSY model): mapping from convolution bands to partition bands was broken since we replaced tables by own calculation several years ago
- Fixed (PSY model): loss of fraction in equal loudness weighting
- Fixed (PSY model): in NSPSY highpass filter, out of bounds access in fircoef
- Known problem samples for the new VBR code: many of them are at an acceptable quality level now; with a big 'Thank You' to Francis Niechcial
- Restricted bitreservoir size for 320 kbps frames to the size used for sideinfo, because of decoding problems with FhG decoders installed on almost every Windows system
- LAME aborts on unsupported input files or unrecognized parameter options passed more often now
- Fixed: [ 1596306 ] "fatal error during initialization"; an invalid MPEG samplerate was returned by optimum_samplefreq function
- Feature request: [ 1588283 ] Flushing output stream in lame.exe; 'flush' option added
- Bug tracker item: [ 1585942 ] lame not --silent when TERM not set; in case LAME was build with TERMCAP defined and no TERM environment is defined, now we do not issue an error message and silently fallback to the default behaviour as if LAME was compiled without TERMCAP defined.
- Added FFTSSE and FFT3DNOW assembler code from Lame4 branch
- Changes in lame frontend switches: -k removed, add lowpass and highpass switches if you need to change them; --short/noshort/allshort - degraded into DEVELOPER ONLY switches normal users shouldn't use them; -X -Z degraded to DEVELOPER ONLY switches, -X is too tough to communicate to end users and -Z isn't used actualy
- Fixed some console printing problems
- Windows: ACM code now uses LAME library API only, all references to private include files are removed
- Windows: DirectShow code now uses LAME library API only, all references to private include files are removed.
- Windows: disabled code that resets processor affinity, because this doesn't belong to LAME, but seems to work around some problems the parent process has (in most cases EAC)
• John33:
- Fixed mp2 and mp3 decoding: For mp3 and mp2 decoding, this now yields the same output as foobar2000 but the error checking remains unchanged
• Gabriel Bouvigne:
- VC8 project files
- Added support for x64 under VC8
- Restricted MPEG 2.5 to 64kbps frames
• Takehiro Tominaga:
- SSE version of FFT

Changes in LAME MP3 Encoder 3.97 final:

Recompiled to include mp2 decoding which was omitted, in error, in the original compile. Otherwise unchanged.
• Gabriel Bouvigne:
- Workaround against a short blocks detection issue
LAME MP3 Encoder 3.97 beta 2
• Gabriel Bouvigne:
- Fixed an initialization error when input is not using a standard sampling frequency
- Fixed a possible assertion failure in very low bitrate encoding
- Slight change regarding ATH adjustment with V5
- Reinstated bit reservoir for 320kbps CBR
- ReplayGain analysis should now be faster when encountering silent parts
• Takehiro Tominaga:
- Fixed a possible link problem of assembly code
