This is a parallelized algorithm performing a decomposition of the time-series data into a number of sinusoidal components, disentangling them from the white Gaussian noise. The algorithm analyses all suspicious frequencies, including the ones that look like an alias at a glance, but may become preferable later. After selection of the initial frequency candidates, the algorithm passes through all their possible combinations and estimates their multi-frequency statistical significance...

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.
