    Now most windows users should be able to compile LAME with minimal effort.</li>
  <li> <font color="#ff0000">Robert Hegemann:&nbsp; old VBR:&nbsp;&nbsp; fixed 
    some bugs and Takehiro's scalefac_scale feature (not yet on by&nbsp; default.)&nbsp; 
    older LAME versions did not allow to spent more than 2500 bits of 4095 possible 
    bits to a granule per channel, now fixed.</font></li>

    up the VBR routine resulting in very large files</li>
  <li> Robert Hegemann: found bugs in some sections when using 32 bit floating

    the wrong filesize in the .wav file.&nbsp; Now fixed.</li>
  <li> Mark Taylor:&nbsp; (optional) Vorbis support, both encoding and decoding.&nbsp; 
    LAME can now produce .ogg files, or even re-encode your entire .ogg collection 
    into mp3.&nbsp;&nbsp; (Just kidding: it is always a bad idea to convert from 
    one lossy format to another)</li>
  <li> ?: Bug fixed causing VBR to crash under windows.&nbsp;&nbsp; (pretab[] 
    array overflow)</li>
  <li> Sergey Sapelin: Another bug found in the mpg123 MPEG2 tables.&nbsp; Now

<ul>
  <li> <font color="#ff0000">Mark Taylor:&nbsp; Bug in buffering routines:&nbsp; 
    in some cases, could cause MDCT&nbsp; to read past end of buffer.&nbsp; Rare 
    in MPEG2, even more rare for MPEG1, but potentially serious!</font></li>
  <li> Mark Taylor:&nbsp; MDCT/polyphase filterbank was not being "primed" properly.&nbsp; 
    Does not effect output unless you set the encoder delay lower than the default 
    of 576 samples.</li>
  <li> <font color="#ff0000">Mark Taylor:&nbsp; "vdbj" and "Caster"&nbsp; found 
    several VBR bugs (now fixed):&nbsp;&nbsp; 1.&nbsp; Analog silence detection 
    only checked frequencies up to 16 kHz.&nbsp; 2.&nbsp; VBR mode could still 
    somehow avoid -F mode.&nbsp; 3.&nbsp; VBR mode would ignore noise above 16 
    kHz (scalefactor band 22), Now calc_noise1 will compute the noise in this 
    band when in VBR mode.&nbsp; Not calculated in CBR&nbsp; mode since CBR algorithm 
    has no way of using this information.</font></li>
  <li> Mark Taylor:&nbsp; scalefactor band 22 info (masking(=ATH),&nbsp; noise 
    and energy) now displayed in frame analyzer.</li>
  <li> <font color="#ff0000">VBR code ATH tuning was disabled by accident in 3.81, 
    now fixed.</font></li>

  <li> <font color="#000000">Naoki Shibata:&nbsp; Bug fix in mpglib (decoding)

    now supported!</font></li>
  <li> <font color="#000000">Mark Taylor: incorporated Takehiro's bitstream.c!&nbsp; 
    bitstream.c used by default, but old ISO bitstream code can also be used.</font></li>
  <li> <font color="#ff0000">Scott&nbsp; Manley and Mark Taylor:&nbsp; good resampling 
    routine finaly in LAME.&nbsp; uses a 19 point FIR filter with Blackman window.&nbsp; 
    Very slow for non integer resampling ratios.</font></li>
  <li> <font color="#000000">Iwasa Kazmi:&nbsp; fixed SIGBUS error:&nbsp; VBR 
    and id3 tags were using data after it was free()'d.</font></li>
  <li> <font color="#ff0000">Robert Hegemann:&nbsp; Improved VBR tuning.&nbsp; 
    #define RH_QUALITY_CONTROL and #RH_SIDE_VBR now the defaults.</font></li>

    instead of a bit rate.&nbsp; Default settings based on a compression ratio

    and specify any integer bitrate from 8 to 320kbs with -b.</li>

</ul>
<h3> LAME 3.69beta&nbsp;&nbsp; April 6 2000</h3>
<ul>
  <li> "spahm":&nbsp; default mode selection bug fixed.&nbsp; In some cases, lame 
    was defaulting to regular stereo instead of jstereo when the user did not 
    specify a mode.</li>
</ul>
<h3> LAME 3.68beta&nbsp; April 4 2000</h3>
<ul>
  <li> Mark Taylor: mono encoding bug in DLL fixed.</li>

  <li> <font color="#000000">Ingo Saitz:&nbsp; Problems with framesize calculation 
    when using -f fast-math option fixed.</font></li>
</ul>
<h3> LAME 3.66beta March 21 2000</h3>
<ul>
  <li> Bug fixes in BladeEnc DLL, possible click in last mp3 frame, VBR historgram 
    display, byteswapping option, ASM quantize routines work for both float and 
    double.</li>
</ul>
<h3> LAME 3.65beta&nbsp;&nbsp; March 17 2000</h3>
<ul>
  <li> Enabled ASM version of quantize_xrpow() - accidently disabled in lame3.64.</li>
</ul>
<h3> LAME 3.64beta&nbsp; March 16 2000</h3>
<ul>
  <li> Don Melton:&nbsp; id3v1.1 tags &amp; id3 bugfixes</li>
  <li> <font color="#ff0000">Gabriel Bouvigne:&nbsp; L/R matching block type fix</font></li>
  <li> <font color="#ff0000">Bug fixed which was allowing quantized values to 
    exceed the maximum when not using -h</font></li>
  <li> <font color="#3366ff">Mark Taylor: Fitlers based on polyphase filterbank.&nbsp; 
    should be slightly better since the responce is independent of the blocktype, 
    and they are slightly faster.</font></li>
  <li> Mark Taylor: API:&nbsp; the API changed slightly - and this should be the 
    final version. There is a new routine: lame_encode_buffer() which takes an 
    arbritray sized input buffer, resamples &amp; filters if necessary, encodes, 
    and returns the mp3buffer.&nbsp; There are also several new #defines, so it 
    is possible to compile a simple encoding library with no decoding or file 
    I/O or command line parsing.&nbsp; see the file API for details.</li>
  <li> Mark Taylor: MSVC stuff:&nbsp; lame.exe (with and without the frame analyzer) 
    and the CDex lame_enc.dll</li>
  <br>
  should compile under MSVC.&nbsp; The MSVC5 project files may need some tweaking.&nbsp; 
  In particular, <br>
  you need to make sure LAMEPARSE, LAMESNDFILE and HAVEMPGLIB <br>
  are defined.&nbsp; (and HAVEGTK for the GTK stuff).
