lame 3.98.4 encoder.zip

lame 3.93 encoder.zip

2010년 3월 22일자로 새로 나온 lame 3.98.4 버전 인코더

CD에서 MP3 추출할 때 쓰는 인코더이다.

3.93버전이 음질이 좋았고 3.98버전은 나름 답답한 느낌이 있는데

간만에 나온 3.98.4는 해결되었을까?

Starting with LAME 3.0: 

red = features and bug fixes which affect quality 
blue = features and bug fixes which affect speed 
black = usability, portability, other

LAME 3.99 alpha 2   not yet released

• Rogério Brito
  • Improve Debian packaging.
    • Include suggestions made by Fabian Greffrat
    • Update version of the Debian package to reflect that it is taken from CVS.
    • Get rid of a transitional package
    • Much more to come...
  • Minor fix to validate the history file correctly
• Robert Hegemann
  • Porting of LAME mp3rtp program to Windows platform

LAME 3.98.4    March 22 2010

• Joseph Flynn
  • Improvements for LAME DirectShow filter:
    • Added support for the DirectShow IAMStreamConfig Interface to the LAME encoder filter output pin.
    • Modified the DirectShow filter registration section so that the LAME Encoder filter is correctly registered in the Audio Compressors filter category. This will allow third-party encoding applications using the DirectShow System Device Enumerator Interface to correctly detect the LAME encoder when querying the Audio Compressors filter group.
    • Modified the filter registration information so that the MP3 audio subtype is correctly reported as being supported on the encoder output pin. This will allow third-party encoding applications using the DirectShow IFilterMapper2 Interface to recognize that the LAME encoder supports MP3 output.
    • Altered the Filter Merit Value that was being used when the filter was registered so that it is now using the standard DirectShow compressor filter merit value of MERIT_DO_NOT_USE (0x200000). Previously, the filter was being registered using a value of MERIT_SW_COMPRESSOR (0x100000), which was at a lower priority (i.e. worse priority) than MERIT_DO_NOT_USE. This prevented the LAME Encoder filter from being selected for use by some third-party encoding applications.
    • Added code to calculate the frame length of the audio frames used for the nBlockSize element of the WAVEFORMATEX output structure. Previously this value was simply hard-coded to 1.
• Robert Hegemann
  • Fix for Bugtracker item [ 2973877 ] A problem regarding the new drain code

LAME 3.98.3    February 27 2010

• Rogério Brito:
  • Update the debian packaging for the new release.
• Robert Hegemann
  • The ignore-tag-errors switch had no effect when embedding album art, fixed.
  • Library API change: lame_decode functions are now obsolete but still present, please use hip_decode instead. The reason for this change is: lame_decode functions use a single global variable within the library to store decoder setup, hip_decode functions don't. The encoder now uses hip_decode internally and it is now possible to use clipdetect feature while reencoding mp3 to mp3.
  • Workaround for FFMPEG bug, which uses to call lame_encode_flush more than once in a loop.
  • Windows: program icon and version info added (when building with VC9)
  • Fix for Bugtracker item [ 2688413 ] lib name problem in Microsoft Visual Studio 6
  • Fix for Bugtracker items [ 2051870, 2423650, 2928684 ] several small documentation issues
  • Fix for Bugtracker item [ 2723518 ] resampling in 3.98 and 3.99alpha
  • Fix for Bugtracker item [ 2891879 ] Because of Windows API change, there was a problem with the prority switch.
  • Fix for Bugtracker item [ 2893101 ] Access Violation in BladeMP3EncDLL if UNICODE was defined.
  • Fix for Bugtracker item [ 2887359 ] Wrong length in ID3v2 tag when num_samples isn't set
  • Fix for Bugtracker item [ 2872590 ] LameTAG: "Music length" missmatch in LAME 3.98
  • Fix for Bugtracker item [ 2824296 ] wrong enc_padding value in LAME 3.99a and 3.98.3 (from CVS)
  • Revisiting the FhG decoder problem (FhG V1.5 build 50, ships with MS Windows): enabling the new-drain-code seems to solve that issue better, than restricting the buffer size (see below: 3.98 beta 1, May 16 2007).
  • Patch submitted by Bernhard Doebler, tracker item [ 2807676 ] Error when building Lame with NASM support
  • Patch submitted by Mancuso Raffaele, tracker item [ 2406420 ] compile lame_enc.dll under cygwin

  • Fix for some tagging issues:
    • Made search for ID3v1 genres more sloppy, abbrevations may match more often as some simple typos. Examples:
      • --tg "Alt. Rock" matches genre "Alternate Rock"
      • --tg "acapela" matches genre "A Cappella"
    • New switch --pad-id3v2-size "n": adds ID3v2 tag with n padding bytes.

  • Found and fixed some suspicious code in additive masking calculation for VBR-NEW
  • bug-fix:experimental code was defaulted by accident for VBR-NEW
  • fix for some endianess problem on big-endian machines

LAME 3.98 beta 7   April 6 2008

• Robert Hegemann:
  • libmp3lame API: allow frontends to separately retrieve LAME/Xing and ID3 data, because the old library automatism makes it impossible to make fully buffered encodes.
  • libmp3lame API: added some experimental unicode ID3 tagging code.
  • frontends: write itself final ID3 tags and LAME/Xing header frame
  • lame_enc.dll: writes itself final LAME/Xing header frame
  • Latest changes to the new VBR psymodel:
    • uses a different spreading function
    • bug-fix for out-of-bounds array access (program stack corruption possible)

LAME 3.98 beta 6   December 16 2007

• Robert Hegemann:
  • Feature request [ 1811483 ] WAVE_FORMAT_EXTENSIBLE support (PCM)
  • Fix for some rare scalefactor selection issue the newer vbr code had at low compression levels
  • Fix for Bugtracker item[ 1813496 ] AIFF parsing bug

    • some more tuning has been done for this new psy model. Many thanks to Horst Albrecht and Myles Thaiss.
    • the "out-of-bits" strategy is reworked
  • It was possible, that the "interchannel masking effects feature" was used by the dual-channel-mode for bi-lingual encodings too. It was meant to work on stereo L/R channels only.

LAME 3.98 beta 5   August 12 2007

• Jonathan Stott:
  • Bug tracker items: [ 1590693 ] ID3v2 tag not writing, [ 1636267 ] ID3v2 tags overwritten
    If the output file is opened 'write-only', then LAME can't update the LAME tag. In this case LAME silently overwrote the first bytes of the file and an optional ID3v2 tag disappeared. Now an error message will be printed and no data is written in this case.
• Robert Hegemann:
  • Fix for Bugtracker item [ 1719593 ] Track numbers > 255 not allowed even with --id3v2-only
  • Fix for Bugtracker item [ 1742623 ] fail(lame --mp3input -m m -b 128 --resample 8 *.mp3 **.mp3)
    The problem here was, the input files are MPEG-1 Layer2 files named as MP3s. Even if you leave out the --mp3input switch LAME tried to decode the input files as Layer3 files because of the file name extension and because it found some valid looking Layer3 synchronization header. The fixed LAME version does not assume the file name extension is always correct and treats the files depending on the first found MPEG sync word. The files in question are now correctly detected as Layer2 files and transcoding does succeed.
  • Fix for Bugtracker item [ 1445175 ] Input being stdin fails in Windows on WAV files
    The problem here was, seeking on pipes shows some different behaviour depending on C-Library implementations. The workaround tries to detect it's working on a pipe and doing some reading instead of seeking in that case.
  • Fixing some memory leak in the 'lame_enc.dll'.
  • Fix for Bugtracker items [ 1160757, 1160741 ] --little-endian / --big-endian not working
    These switches where originally intended to be used together with Libsndfile only.
  • Fix for Bugtracker item [ 1746336 ] Incorrect Bitrate with ABR und --resample, LAME 3.98b4
    Some earlier bug-fix had some typo. As a result, when adding a '--resample 123' switch, the average bitrate rised upto maximum bitrate.

LAME 3.98 beta 4   June 23 2007

• Dennis Lambe Jr: Added support for total track count (id3v2) in the frontend
• Nyaochi:
  • Ability to set user-defined ID3v2.3 frame
  • Ability to include albumArt in ID3v2.3 tag
• Robert Hegemann:
  • Bugfix: the "play length in ms", which is stored in the ID3v2 tag TLEN, was not correctly computed. Some hardware and software players were confused by this garbage data.
  • Out of bits strategy for the newer VBR code overhauled
  • LAME API: the ID3 tag functions do not store the pointers passed anymore, they do make deep copies of strings passed as parameters.
  • Changes in LAME frontend switches regarding ID3 tags: 
    --tg "MyGenre" will route unknown ID3v1 genres to "Other" for ID3v1 tags and will be stored as plain text "MyGenre" for ID3v2 tags. Genres given by known ID3v1 numbers will be stored as its corresponding text in ID3v2 tags. 
    --tn "02/02" will store the track number specified as plain text as-is for ID3v2 tags.

  • Bug tracker item: [ 1711980 ] LAME writes invalid Xing header when ID3 tags exist; LAME was sometimes writing an invalid Xing/Info header
  • Feature request: [ 1588283 ] Flushing output stream in lame.exe; 'flush' option added
  • 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)
