;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)
;
;0.6: SuperMP3 (not finished and its future in the dark) 19/08/2005
;Author: Sergey Kuzmin aka Wildwest <kuzmin_serg@list.ru>
;Additions: Alexei Ershov aka ealex <e-al@yandex.ru>
;Features: added checking of CRC bit;
; improved frame_size calculation (thanks to Alexei Ershov for the formula)
; added ID3v1 tag reading (except Genre field) by Alexei Ershov

;--------------------------------------------------------------------------------------
;0.3: SuperMP3 25/04/2005
;Author: Sergey Kuzmin aka Wildwest <kuzmin_serg@list.ru>
;Features: added File_size and Duration (rough estimation), improved SampleRate, fixed BitRate
;--------------------------------------------------------------------------------------
;0.2: SuperMP3 21/04/2005
;Author: Sergey Kuzmin aka Wildwest <kuzmin_serg@list.ru>
;Features: added SampleRate and BitRate
;--------------------------------------------------------------------------------------
;0.1: SuperMP3 20/04/2005
;Author: Sergey Kuzmin aka Wildwest <kuzmin_serg@list.ru>
;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 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
