Spectro-Edit reads in regular PCM audio files, then shows the audio visually in a time vs. frequency plot. The fun part is that you can "paint out" any part of the visualization and play back the audio subject to your modifications. When you are happy with the result, you can save your work back to a WAV file. This could be useful for podcasting (edit out microphone noise, chair squeaks, phones ringing, and other background noise), music (make strange and unusual modifications to the sound for artistic reasons), research (visualize animal calls or noise pollution from nearby industrial activity), and general purpose geekery (which was the original purpose). License: GNU General Public License v3 Changes:
This release adds many improvements, including undo/redo and a continuous readout reporting cursor position (frequency (y axis) and time (x axis)). The brightness slider is now faster and the user interface more thoughtfully laid out. The "scale region" tool now uses a slider with realtime preview instead of two buttons, and the new tool chooser features several new tools, including "flip" (x or y) and "clip to threshold". The window is now never wider than the screen when opening a lengthy clip.
