;HISTORY: 

;0.7:       MP3INFO                                            23/09/2018
            Sergey Efremenkov aka theonlymirage
            adopted app to use system f70 instead of old f58
            Kiril Lipatov aka Leency make app to open with param, small UI update

;0.65:      SuperMP3
            Madis Kalme rewrited extract_bits (he used his Extracteax macro) 
            and decode_bitrate functions

;0.64:      Xing header reading: correct time, bitrate and number of
            frames for VBR files	
;0.62:      ID3v2 detecting and writing its version
;0.61:      Header search 
;           Added 'Header found at' field 
;           If file has no frames, error message is shown 
;           Russian tag support (in windows-1251 encoding)
;

;Features:  able to detect MPEG Version, Layer, Channels
;----------------------------------------------------------------------------------------  
;Issues:   
; MP3 player needs work of several men during several months(approx. 10 men and 2-4 months, because it is ASM OS). 
; If you want to listen a lot of mp3 in MenuetOS - make a bit of asm!         
;----------------------------------------------------------------------------- 
;CLEAN mp3 - is mp3 file without any info before header. Open mp3 in HEX EDITOR and check it out. 

;Usually normal header's start looks like FFF3 or FFFB.

;If you see TAG (4944 3303 = ID3.) or RIFF (5249 4646 = RIFF) 
;or (0000 0000 - encoded by Lame codec or another shitty program) - it is bad, 
;you must delete this piece until FFFx before testing. Happy testing!

;Note - I test it only on several files (test.mp3
;included in this package) in Bochs and Qemu.
;For testing change name if the end of "supermp3.asm" - section
 fileinfo:
  dd 0, 0, 1, mp3_file, 0x1000
  db "/SYS/TEST.MP3",0 

Package content:
readme.txt - this file
supermp3 - compiled exacutable file
supermp3.asm - main file - build program's GUI
MACROS.INC  - standard file with macroses
MOS_UZIT.INC - macroses for interface, routines for extracting bits and decoding extracted bits
ASCL.INC - macroses for interface and useful stuff
test.mp3 - test file
