Spectro-Edit 0.3 (Default branch)
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).

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.
