If you would like to access this software under a different licence then please get in touch and ask.

Summary of the similar EUPL v1.1 from TL DR Legal.

If you modify the library and use it in some software that you provide to others, even if the library is not distributed to the users, then you must provide your modifications to the library back to the community so that everyone can benefit.

So basically, if you use the library as-is in some piece of software then that's just fine (though an acknowledgement would be nice) and you can even keep the software closed-source should you wish to. Of course, if you want to open source software that links to this library then you are free to do so. My intention is also that this library can be used as a library by other pieces of software but that the EUPL v1.2 licence does not have to be applied to the software that links to it (this is similar to the LGPL licence). In contrast to many open source licences, the EUPL v1.2 licence makes it clear that modifications must be made available even in the case of the library being used as part of a web service and not distributed to the user, covering the 'Application Service Provider loophole' (in this case it is similar to the AGPL licence). My intention in using EUPL v1.2 is primarily to ensure that any modifications to this library are made available to the community as source code. The EUPL is an 'open source' licence: one of many options and one in the 'weak-copyleft' category. Comments below do not constitute the licence, they are just my comments on the licence.

Two files ( morse-pro-util-riffwave.js and morse-pro-util-datauri.js) are Public Domain. It has been written using ES6 (ECMA Script 6).

Decode from listening to the microphone or an audio file, adapting to the most prominent frequency.

Adaptively decode to text, adjusting to the most likely speed and Farnsworth speed.

Decode to text given 'on' and 'off' timings and a fixed speed.

Take Morse code input from a web-based keyer or iambic keyer.

Generate in-browser sounds using the Web Audio API and falling back to other methods such as Flash for older browsers.

Make use of the "Farnsworth speed" concept of extending the gaps between characters and words.

Generate downloadable RIFF WAVE ('.wav') files of Morse code at given frequency and speed.

Translate to and from text and Morse code (in the form of '.

It is the library used in the tools on Stephen C Phillips's Morse code website. This Javascript (ES6) library is for manipulating Morse code text and sound.
