This free online service converts a message into morse code and vise versa.
The morse code is converted into an audio MIDI file which can be played and downloaded.
The morse code and correspondig readable message are both stored in a text file which also can be downloaded.
This tool uses the international morse code, where the following rules are applied:
A dot is one unit long.
A dash is three units long.
An intra-character gap (between the dots and dashes within a character) is one unit long.
The space between two letters is three units long.
The space between two words is equal to seven units long.
