AMR檔案格式分析與轉換

This is a simple script I wrote in perl to convert between AMR and diferent audio formats (WAV, MIDI & MP3).My Script has this Input/Output Diagram:                       .-----------.                     -->|  MID/MOD  |                        `-----+-----'                              |                          timidity       |                     |                                                             |       v                     v                                                             v  .---------.         .-------------.       .-------.          .-----------.           .-------.  |         +--mp123->|             |       |       +--encode->|           +--ifs2amr->|       |  |   MP3   |         |     WAV     |<-sox->|  RAW  |          |  AMR-IF2  |           |  AMR  |  |         |<--lame--+             |       |       |<-decode--|           |<-amr2ifs--+       |  `----+----'         `---------+---'       `-------'          `-----------'           `---+---'       |                  ^     |                                                          |       v                  |     v                                                          v        You will need this programs to use this script:timidity         http://www.onicos.com/staff/iz/timidity/dist/download.html Program                 http://www.stardate.bc.ca/eawpatches/eawpats12_full.rar    Patchessox              http://sox.sourceforge.net/lame             http://lame.sourceforge.net/mpg123           http://www.mpg123.de/Encoder decoder  ftp://ftp.3gpp.org/Specs/latest/Rel-5/26_series/26104-520.zip                 compiled with this changes: makefile without -DETSI                 added #include "sp_dec.h" to decoder.c                    To find more info about AMR and MMS check this pages:MMS InfoAMR InfoAMR file formatSPOT XDE PlayerAMR converter for Windows (Not tested)AMR comverter for WindowsConversion between AMR (Adaptive Multi-rate Codec) file formatsMMS DiaryThanks to Stefan Hellkvist for his comments.If you need more info just E-mail me to amrconvert@xa.bi
