cw2mp3
A simple UNIX C tool to generate .mp3 practice files of CW (Morse Code) from text files.
Source Code:
- Download POSIX C source file: cw2mp3.c
- Download source code archive with sample text files included: cw2mp3.tgz [9 kb]
.mp3 sound files to practice with:
- Message 1 (5 wpm, 1x Farnsworth): [message1.mp3 (2MB)]
- Message 2 (10 wpm, 2x Farnsworth): [message2.mp3 (14.4MB)]
- Message 3 (10 wpm, 2x Farnsworth): [message3.mp3 (6.9MB)]
- Message 4 (15 wpm, 4x Farnsworth): [message4.mp3 (37.4MB)]
- Message 5 (20 wpm, 3x Farnsworth): [message5.mp3 (51.9MB)]
- Message 6 (20 wpm, 3x Farnsworth): [message6.mp3 (0.8MB)]
- Message 7 (20 wpm, 3x Farnsworth): [message7.mp3 (26.1MB)]
- Message 8 (20 wpm, 3x Farnsworth): [message8.mp3 (92.7MB)]
Note: The above files were all encoded using various multiples of "Farnsworth" (additional) spacing between letters and between words to give you a chance to keep up. Listen and write it down- don't try to keep the letters in your head while decoding!
Good luck - I'll be monitoring!
