In this project, a perfect PCM sine wave is one that contains a single frequency at 0 dBTP and no error harmonics at all. A bit-perfect PCM sine wave has error harmonics due to encoding quantization, but they are at the minimum level possible for the chosen encoding. The generated wave files hold a sequence of one or more complete copies of a repeating pattern. A file containing a single pattern can be played in a loop to extend the play time.

Reads audio from Windows audio interface or wave file and creates a continuous spectrum display. Command line support for generating sine, square, triangle and sawtooth wave files. Uses biquad IIR digital filters for frequency detection, plus digital lowpass filters for output extraction. Highly configurable. 60+ FPS with suitable hardware. Manual or automatic gain control.

QxCalc For mathematical calculations in high-school, physics, chemistry, mathematics, economics, electrical, mechanical. Create equations, and also calculate with them, with ease. You use the calculator the same way as you use a pen and paper. It is quite simple, and can do a lot of work given syntax correctness. It comes with a "basic" gui, however the best way to use it is with the 'vim' editor, for which it has a syntax highlight file (calc.vim).

Keep simple things simple: You want to plot a sine function? Just enter 'plot sin(x)'. You want to load some data? Enter 'load "path/to/your/file"' or drag the file into the terminal. You need to fit a function to the data? Enter 'fit data() -with=YOURFUNCTION(x)' Need assistance? Enter 'help topic' into the terminal or simply press [F1].

Musical instrument strobe tuner: a real-time emulation

This program is a soundcard based signalgenerator and oscilloscope for low frequency and low voltage signals written for linux using the alsa api. It uses the internal DAC/ADC of the soundcard (PCM) to capture signals or generate them. Depending on the available PCM device, it's possible to generate or capture signals up to 96 Khz.

Ceasar is an open-source multi-frequency tone gereator for UNIX, initially Linux. By default it contains standard DTMF tones together with C5 (bluebox) tones.
