Wavicler

Tool for manipulating and slicing audio waves. The general idea is to use it to chop up pieces of audio into chunks that can be used in a music production DAW. The selection can be by sample, time, or beats (based on user supplied BPM). Note that internally everything is referenced by sample index.

Caveats:

  • Everything internal is 32 bit fp 44100Hz.
  • Uses int for sample index. This gives us a theoretical maximum clip time of about 1.3 hours. In actuality it uses a setting from AudioLib to limit this (default is 10 minutes). This gives plenty of time for the purpose of this application.

UI

Main

  • Standard file menu.
  • Open an audio file. This is a now a clip in a clip editor tab page.
  • Double click the tab to close the clip.
  • If it's a stereo file the user is asked to open as left, right, mono, or both.
  • Selection play, rewind, loop on/off, auto-start on/off.

Selection

  • Time mode:

    • Select two times using ?? resolution.
    • Shows number of samples and time in UI.

  • Sample mode:

    • Select two samples using ?? resolution.
    • Shows number of samples and time in UI.

  • Beat mode:

    • Establish timing by select two samples and identify corresponding number of beats.
    • Show in waveform.
    • Subsequent selections are by beat using snap.

Keys

  • G: Reset gain.
  • H: Reset to initial full view.
  • M: Go to marker.
  • S: Go to selection.
  • F: Snap fine.
  • C: Snap coarse.
  • N: Snap none.

Mouse

  • Wheel alone is time shift (x shift).
  • Wheel + ctrl is time zoom (x zoom).
  • Wheel + shift is gain (y zoom).
  • Left dblclick alone sets marker.
  • Left dblclick + ctrl sets selection start.
  • Left dblclick + shift sets selection end/length.
  • Right click opens context menu.

Context Menu

  • Most of the Keys functions.
  • Set gain to fill or reset.
  • Copy selection to new clip.
  • Close.

Tools

  • Stereo file split into two wavs.
  • Stereo file combine to mono wav.
  • Resample file to 44100 32bit wav.
  • Edit settings.
  • About.

Future?

  • Combine multiple clips, incl blank.
  • Edit: cut/copy/paste/insert.
  • Gain envelope.
  • Stretch/fit etc.
  • Detect tempo.
  • Mouse/kbd/context commands user configurable.
  • Snap settings user configurable.
