Morris

This program generates Morse tones to standard output in real time in raw PCM. It attempts to be cross-platform, with no dependencies apart from the C++ standard library.

Usage

Run the executable and type. The tones will be sent to standard output whenever the return key is pressed. The return key also signals a space character in the output.

The following example shows how to output live sound on Linux using aplay

./morris | aplay -f S16_LE -c 1 -r 48 -

Note that morris outputs 16-bit signed samples in one channel at a 48 kHz sampling rate.
