16 August 2000
absthr.h, critband.h, freqtable.h
	- new include files contain the tables/ directory
tables.c 
	- includes the alloc_* files from the tables/ dir
options.h, get_audio.c
	- added 'byteswap' command line switch with -x

25 April 2000
*	
	- changed printf()s to fprintf()s. Everything goes to stderr, except usage().
		(Not sure if this is 'the right thing'. but its neater than before)
toolame.c
	- stdin/stdout now referenced with '-'s as in lame. (-DIOFIX)
		eg ./toolame - - >dud.mp2  will encode from stdin, to stdout (with 
		redirection to 'dud.mp2')
encode.c
	- Started work on VBR_bit_allocation.


22 April 2000 v0.2g
Makefile
	- OS/2 bits by Nick Burch <gagravarr@SoftHome.net>
availbits.c
	- made the calculation of the bits (adb) a standalone function (prep for VBR)
common.c
	- fixed js_bound to be layer2 only
	- fixed bitrate[][][] table to be layer2 only.
*	
	- VBR switch activates a simple VBR mode.  The bits required to encode with 
	  no noise are calculated in VBR_bits_for_nonoise.

* 	- removed most of the references to 'layer number' and hardcoded for layer2.

16 April 2000 v0.2f
* *.c
	- general code cleanup.  Deleted lots of obsolete stuff.
	- ran it all through 'astyle' to try and get some style :)
* *.h
	- turfed out a lot of guff in the header files.
* psycho_I.c
	- renamed Psycho_One() to psycho_i()
	- combined the hann + f_f_t + pickmax functions functions
		this removes some buffering and a whole bunch of log10 calcs in pickmax.
* psycho_II.c
	- renamed psycho_anal to psycho_ii()
* common.c
	- split common.c into more logical subunits
		mem.c - memory handling functions
		crc.c - the crc stuff
		bitstream.c - bitstream handling code
		tables.c - table handling code
		common.c - miscellaneous mpeg handling/init routines.
* Makefile
	- tweaks for gcc2.95.2
	- added more warnings to fix my dud coding style.

14 December 1999
* encode.c
	- change to scale_factor_calc from PDS (Patrick De Smet 
		pds@telin.rug.ac.be) 44% faster by using binary search 
		rather than linear. (#define PDS1)
	- change to subband_quantization from PDS. A little faster.
		(#define PDS3)
	- NB. these changes by PDS do not produce bit exact output 
		when I think they should.

* *.c	
	- changed all C++ style comments to C style.

* subband.c
	- merged filter_subband and IDCT.
	- put table/enwindow into enwindow.h

* musicin.c
	- fudged a bit with the input file parsing. 
		Accepts WAV, AIFF and defaults to PCM.
	- Can read raw PCM from /dev/stdin in a pretty kludgy way. 
		(use '/dev/stdin' as the input file.)
		I'm sure someone will tell me why this is a really bad 
		thing to do.
	- Changed the print_config a little. Feel free to change 
		it and get something nicer looking.

5 November 1999
* fft.c
	- included table_lookup modification for fht() from Mathew Hendry 
		<math@vissci.com> 20% speedup
	- modified fht() to be for n==1024 only. that's all that's 
		ever needed for LayerII encoding
* *.c
	- removed "II_" prefixes from all the functions (superfluous 
		now that code is layerII only)
* tonal.c
	- made add_db() an inline function by separating its init 
		function into init_add_db()
* psy.c 
	- renamed to psycho_II.c
* tonal.c
	- renamed to psycho_I.c
* psycho_II.c
	- cleaned up memory alloc'ing. Might just make it all explicit 
		size def'n instead of mallocs.
	- turned off layerI and III stuff
	- tuned some loops (fft buffer filling)
	- replaced loops to initialize values to zero, with memset()
* Makefile
	- added a few more switches which work well on my p166/linux/gcc setup.

2 November 1999
* musicin.c  
	- frameNum bug fixed (incorrectly incremented it twice every 10th 
		frame)
	- a "no padding" switch for those using some layerII editing programs
		that don't work with padding. afaik, this is a major
		hack on the format - mpg123 still groks the files.

				Bill Eldridge <bill@hk.rfa.org>
* tonal.c
	- threshold()  changed some of the if() checks. 33% speedup.
	- add_db() tweaked it a little more. 25% speedup

30 Octover 1999
* musicin.c
	-added "quick mode", where you can specify how often to calculate 
		the psy model.  e.g "-q 10" calculate psy model once every 
		10 frames, and then use those ltmin values for the next 
		10 frames
	- now reads WAV files thanks to Nick Burch <gagravarr@SoftHome.net>
* musicin.c/encode.c
	- reimplemented -a "downmix to mono switch".

24 October 1999
* Started using dist10/lsf/encoder as the original source code.  This is the same base code from which LAME patches.  This code (for layer2) is more complete than the previous archive as it contains LSF.
* added in most of the previous changes (still quite a few to go)
* No layerI or layerIII support.

17 October 1999
* tonal.c
	- tweaked add_db a little. Removed superfluous code. 
		Maybe separate the table initialization, and make the 
		function inline 
	- tweaked threshold(). removed superfluous if() checks and changed some
		variable usage.  10-15% speedup.

16 October 1999
* tonal.c
	- integrated hannwin, fft, pickmax into II_psycho_one()
* tonalI.c 
	- created, and put all the LayerI stuff in there.  LayerI
		stuff will be left in source for the time being

15 October 1999
* encode.c
	- added downmix (-a) option to get_audio()
* encoder.h
	- changed defaults to be psy model 1, 192 kbps, with extension .mp2
* fft.c
	- implemented FHT-based fft() from LAME. 
* tonal.c
	- tweaked II_f_f_t to call fft.c/fht() routine
* encodeII.c
	- include PDS' II_scale_factor_calc


14 October 1999
* musicin.c
	- no longer use obtain_parameters(). interactive input is just a pain.
	- progress meter updated to print every 10th frame.
	- added 'usepsy' switch (-f) which will turn off all psychoacoustic 
		calculations for layerII. (could easily be extended to layerI)
* musicout.c
	- removed
* tables/dewindow
	- removed
* decode.c
	- removed
* decode.h 
	- removed
* subs.c
	- renamed to fft.c (that's all it does anyway :)
	- replaced old fft with fft from LAME2.x
* tonal.c
	- new add_db added
* subband.c
	- created
	- moved window_subband and filter_subband from encode.c to here
	- LAME versions of these routines replaces ISO routines.
* encode.c
	- split into encode.c, encodeI.c, and encodeII.c
	- encode.c - generic encoding routines
	- encodeI encodeII - layer specific routines. (easier to grok)
