ag-works has released beta versions of two new free VST plug-ins for Windows. Sonogram SG-1 is a real-time sonogram allowing for fast and detailed spectral analysis. Chorus CH-1 is a rich chorus effect using "all-pass interpolation" to achieve better frequency modulation quality.

Sonogram SG-1 Features:

• Six scientific color palettes, each of them can highlight different dynamic ranges, from high power kick drum beats, to little spikes coming out from the noise floor.
• Snapshots-per-second control that can be changed on the fly, to increase or decrease the time resolution.
• At any time you can change the zoom ratio, without loosing frequency details for the signals which have already passed by.
• The zoomed screen can be scrolled while analyzing, to easily locate the frequency range of interest.
• Pause the visualization with the "freeze" control.
• Both in frozen or running mode, every time you click or drag within the sonogram area, frequency and amplitude rulers highlight the values corresponding to that point.
• Every palette can be shifted by simply dragging the dB ruler, to better contrast the right amplitude ranges.
• A mark button is provided to highlight interesting parts of the waveform for subsequent individuation.
• Every parameter supports host automation.

Chorus CH-1 features:

• Up to 10 voices.
• Brilliant and clean tone (for guitars, voices and pads).
• Extremely wide stereo effect.
