ebook2cw ebook2cw is a command line program which converts a plain text ebook to Morse
code audio files. It works on several platforms, including Windows and Linux.
A number of CW and audio parameters can be changed from their default values, by
command line switches or a config file (see below). These are (default values in brackets):
-w wpm - CW speed in words per minute 
-e wpm - Effective CW speed. If set, the spaces are sent at this speed instead of the
character speed set by -w ("Farnsworth").
-W x - Extra Word spacing. Similar to -e, but only affects the inter-word spacing,
not the inter-character spacing.
-f freq - audio frequency in Hz 
-T SINE|0|SAWTOOTH|1|SQUARE|2 - set waveform to sine, sawtooth, squarewave. [sine]
-Q minutes - Increase CW speed (QRQ) by 1 WpM in intervals of minutes. Speed will be
reset to the initial value at the start of each chapter. 
-n - Disables resetting the speed when using the -Q option.
-p - Disables the paragraph separator (<BT>)
-R risetime - risetime, in samples 
-F falltime - falltime, samples 
-O - Use OGG/Vorbis encoder instead of MP3 if compiled with OGG support
-X - Do not encode, do not generate output files
-s samplerate - samplerate for the OGG/MP3 file 
-b bitrate - MP3 bitrate, kbps 
-q quality - MP3 quality, 1 (best) to 9 (worst). CW still sounds very good with the worst quality, encoding time is greatly reduced. 
-c chapter separator - Split chapters at this string. [CHAPTER]
-d duration - Splits output files after "duration" seconds; finishes the current sentence.
-l wordlimit - Splits output files after "wordlimit" words; finished the current sentence.
-o outfile-name - Output filename (chapter number and .mp3/.ogg will be appended) [Chapter]
-a author - Author for the ID3 tag. Use quotes for strings with spaces (e.g. "JW Goethe")
-t title - Title for the ID3 tag. Use quotes for strings with spaces (e.g. "Faust II")
-k comment - Comment for the ID3 tag. Use quotes for strings with spaces.
-y year - Year for the ID3 tag.
-u - Switches input encoding format to UTF-8. Currently supported alphabets
include Latin, Greek, Hebrew, Arabic and Cyrillic. Default is ISO 8859-1.
-g file - Guesses the encoding of file (ISO 8859-1 / ASCII or UTF-8).
-S [ISO|UTF] - Shows a table of all available morse symbols for the ISO 8859-1 and UTF-8
character sets. Output in HTML format.
-N snr - When this option is used, a noise background is added to the file and the CW
signal is scaled down to achieve a SNR (Signal to Noise ratio) of "snr" dB.
Possible range of SNR: -10db to 10dB. Make sure to enclose the value in
quotation marks if its negative (i.e. -N "-3").
-B bandwidth in Hz - Sets the filter bandwidth if the -N / SNR option is used. Available filters
are 100Hz, 500Hz, 1kHz and 2.1kHz.
-C frequency in Hz - Sets the center frequency of the filter if the -N / SNR option is used. This
should be set to the frequency of the Morse signal; currently implemented
center frequencies: 800Hz
