USE IT AT YOUR OWN RISK. THE AUTHOR DOES NOT TAKE ANY RESPONSIBILITY FOR WHAT THIS SOFTWARE DOES TO YOUR PC. BACKUP FREQUENTLY. INTRODUCTION: Ctronome is a very-very simple programmable metronome for Linux console, with /dev/dsp audio output. BPM ranges from 30 to 250, tacts like 3/4, 7/8 etc. are possible. It Uses plays external WAV files, so one could use custom sound samples. Aim is to keep it as simple as it can be so dummies like me may understand and modify it. (The source code looks ugly though;) COMPILE-TIME CONFIGURATION: edit ctronome.h for defaults, the most important ones are: metronomewav1 = "/usr/share/ctronome/metronome1.wav\0"; metronomewav2 = "/usr/share/ctronome/metronome2.wav\0"; dspdev = "/dev/dsp\0"; They speak for themselves. COMPILATION: Only the very basic C libraries are needed that I believe to exist on virtally all Linuxes. You need to have Linux kernel header files installed (they come with the Linux kernel source), and OSS (or OSS compatible) soundcard support. Go into ctronome source directory and type 'make'. It should compile whithout errors. INSTALLATION: Ctronome is a single binary. You can put it anywhere you want in your local or remote filesystem. You need two, preferably short WAV files as metronome sample, put in the place you specified in ctronome.h, or specified on the command line. There are two one-channel and two two-channel (both channels are the same) included, recorded from a real metronome. You have to install the one that fits your sound system (see NOTES) RUNNING: ctronome -b <bpm> -t <bpt> -c <count> -w1 <wav1> -w2 <wav2> -d <dsp_device> \ -p <program> -h -v -b <bpm> beat per minute default: 60/4, range: 30-250/1-20 -t <bpt> beat per tact default: 1/4, range: 1-50/1-50 -p <filename> program file -c <count> play tact/program <count> times then exit -w1 <filename> wav to use for first beat of tact default: /usr/share/ctronome/metronome1.wav -w2 <filename> wav to use for other beat of tact default: /usr/share/ctronome/metronome2.wav -d <device> dsp device, default /dev/dsp -h display help screen -debug display debug messages See prog_example.txt to learn how to program ctronome. For BPM you can specify the base note. E.g. 60/4 means: 60 1/4 notes per minute -> length of 1/4 note is 1 second. For BPT you can also define the base note. E.g. 4/4 means: 4 1/4 notes per tact -> length of a tact is 4 seconds. As you can see, it is now possible to specify the BPM in 1/4 notes, and then you can use BPT like 7/8, ctronome calculates lenght of 1/8 note (which is half of the 1/4 in this example) and plays seven of them for a tact. If the base note for BPM is not specified, it defaults to the base note of the tact. It requires two 16 bit per sample WAV format, mono or stereo, and preferably at least 44100Hz sample rate. *The two WAV formats must be the same!* Please note that if your sound system does not support the exact format provided by the WAV files, it will try its best to play it anyway, but the result will be unpredictable. Debug mode will tell you the details.
