This program will simply output a sine wave of the desired parameters. It can use SDL to output to your sound card, or dump to a file.
See the manpage for full details.
Some examples:
# Play e, e#, f
tune --start e --end f --loop
# Play e, f, g, a'.
tune --start e --number 4 --step 2
# Play starting at A, one octave up from concert pitch.
tune --start a+
# Play a, b, c
tune --loop a b cConvert raw samples like:
aplay -c 1 -f S16_[LE|BE] -r 44100 sinewave.rawAnd encode them with ffmpeg:
ffmpeg -f u16le -acodec pcm_s16le -i sinewave.raw -acodec pcm_s16le -ac 1 output.wavUse cmake as normal. Dragons here since I never updated the buildsystem for quite some time:
$ sudo aptitude install libsdl1.2-dev libboost-program-options-dev cmake \
libboost-thread-dev
$ mkdir _build
$ cd _build
$ cmake ..
$ makeThere is currently no install target.
