Scope ~ Windows Soundcard Oscilloscope


The PC based Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution. The data source can be selected in the Windows mixer (Microphone, Line-In or Wave). The frequency range depends on the sound card, but 20-20000Hz should be possible with all modern cards. The low frequency end is limited by the AC coupling of the line-in signal. Be aware, that most microphone inputs are only mono.

The oscilloscope contains in addition a signal generator for 2 channels for sine, square, triangular, sawtooth wave forms and different noise spectra in the frequency range from 0 to 20kHz. The signal can be defined by a mathematical formula as well. The signals are available at the speaker output of the sound card. These can be fed back to the oscillocope in order to generate Lissajous figures in the x-y mode.

Features:

  • Trigger modes: off, automatic, normal and single shot
  • Triggerlevel can be set with the mouse
  • The signals of the two channels can be added, subtracted and multiplied
  • x-y mode
  • Frequency analysis (Fourier spectrum)
  • Waterfall diagram (frequency spectrum as function of time)
  • Frequency filter: low-, high-, band-pass and band-stop
  • Cursors to measure amplitude, time and frequency in the main window
  • Audio Recorder to save data to a wave file
  • For multi soundcard system, the used card can be selected in the settings tab

Charlatan ~ Virtual Analog Synthesizer Plugin


Charlatan is a polyphonic, subtractive virtual analog (VA) synthesizer VSTi plugin with focus on sound quality and easy usability. It comes with a flexible, yet not overwhelming feature set which encourages artists to start tweaking instead of just relying on presets. In spite of it’s simplicity, Charlatan’s architecture is flexible enough to create both classic sounds and rather experimental noises. While making no compromise about sound quality, the sound engine has been highly optimized for efficient CPU usage making Charlatan well suited as a “bread and butter” synth even in projects with a large number of plugin instances. Best of all, it’s freeware! Enjoy!

Key Features:

  • 2 oscillators with shape modulation
  • Oscillator hard synchronization and ring modulation
  • Unison mode with up to seven voices and stereo spread
  • Stereo noise generator
  • 2 ADSR envelope generators
  • LFO with host tempo synchronization
  • 3 filter types modeled after classic analog hardware: 4-pole (24 db/oct) and 2-pole (12 db/oct) lowpass, bandpass
  • 3 voice modes: Monophonic, Monophonic Legato and 8-voice Polyphonic
  • Ultra-low CPU usage

foo_pggb_rt ~ Foobar2000 Realtime Resampler


foo-RT – A PGGB-RT foobar2000 (Windows) component up samples or down samples your audio tracks in near real-time fashion using insanely long linear filters. We are able to do this by using hardware acceleration PGGB-RT SDK. We say ‘near real-time’ because remastering using insanely long filters require a finite time. Depending on the length of your track and the filter length (in millions of taps) you choose, the very first track will take anywhere from a few seconds to a few ten seconds to start. The subsequent tracks would play in a gap-less fashion
