Spectro-Edit 0.4

View and modify audio in the frequency domain
Spectro-Edit is a software written in Java that reads in regular PCM audio files (currently, only 16-bit mono WAV is supported), then shows you the audio visually in a time vs. frequency plot.

The fun part is, 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 is why I made it).

What's New in This Release:
  • New features include: improved visualization with more user control, and optional use of colour to double the displayed value resolution; exponential sliders, which greatly improves their useful range; the cursor position readout now shows the nearest musical note name (to the semitone); repositioning of playback by clicking in the header; and the ability to load stereo samples (they are automatically mixed down to mono).
  • Bugfixes include elimination of the audible blip at the end of the clip, and numerous small but noticeable improvements to the shuttle controls and the rest of the GUI.
