This applet is a crude, much weaker version of my old application RGS (for Amiga). Nevertheless, you can play with it a little, and feel free to implement the rest of it.

• Like RGS, you draw sonograms that are synthesized as you draw. laft-right represents time, bottom-top represents frequency, and color represents the amplitude of the sound at that frequency, at that time.
• You place (paint) the sonogram with "sound-marks" that can be changed like normal paint program brushes. The current one is the one showing in "RGS Controls".
  • Ramp: draws a range of color up to the current amplitude and back down to 0.
  • Dots: draws a single point.
  • Line: draws a constant colored line through the whole sound
  • Blob: draws a little square, range sized
  • Wipe: erases a blob sized area
  • Filter: filters teh area under the cursor
  • Down: draws from the high amplitude down to 0, like half a "ramp"
• Controls:
  • To clear the screen - and the sound - type "T".
  • "Range" controls the size of the sound-mark written.
  • "Amp" controls the amplitude (color).
  • "Mix Amp" controls how loud the amp will be in the final sample (too loud will clip and distort the sound).
