WAVE EDITOR / RECORDER
The Equalize Tool is a linear phase EQ and boosts or cuts frequencies according to a user defined EQ envelope. The example below shows the effect of the selected EQ curve on a white noise sample. Frequency is displayed on the
horizontal axis, time on the vertical axis (sample start is at the top, sample end is at the bottom) while intensity/saturation of color represents frequency amplitude.
To Open the Equalization Tool
To open the tool you can either Left-click on the EQ Tool button , press (Ctrl+E)
inside the Editor, or use the Tools > Spectral > EQ option.
Editing envelopes - Right-click in the 'Envelope Editor Window' to add points, and Left-click to move points and tension markers. Right-click points to open a context menu that will allow you to delete points
or change the curve type. The default mid-line is 'no change'. Boost/Cut values appear in the FL Studio Hint Bar as the nodes and tension handles are moved.
Time is represented on the vertical axis and Frequency on the horizontal axis.
- Envelope - Drop-down menu containing harmonically computed EQ envelopes. The harmonic series is based on the sample middle note (root note). Set this using the
Sample properties dialog. The harmonic envelopes will remove sounds that do not belong to the harmonic series of the set note. These envelopes can be useful for extracting sustained notes from complex
recordings or removing noise from recordings of tonal sounds.
- To filter non-harmonic noises
- 1. Set the middle note (root note) using the (F2)
Sample properties dialog.
- 2. Open the Equalization Tool, Envelope options and select from narrow, medium or wide.
- 3. Use the Frequency scale knob to expand the lower frequencies to check that the filter envelope is starting at the correct frequency and covers the harmonics.
- 4. Set the Mix knob to the desired level, 100% to retain only the harmonic series.
- 5. Select Ok.
- To remove a note from a sample
- 1. Perform steps 1 to 5 above.
- 2. Select Tools > Amp > Reverse polarity.
- 3. Select Tools > Edit > Copy to Copy the entire sample.
- 4. Open a new instance of Edison with the original sample.
- 5. In the new Edison select Tools > Edit > Paste mix and the note plus harmonics will be removed from the original sample.
- Freq scale - Zooms the frequency scale for more or less precise EQ editing.
- Mix - Adjusts the level of the dry to wet signal.
- Smooth - Smooths the EQ envelope to reduce unwanted artifacts such as 'ringing'.
- Phases - Allows the envelope to change the phase of the sample, top of scale is 180 degrees, bottom -180 degrees.
- Reset - Resets the EQ envelope to the default state.
- Accept - Applies the EQ curve to the sample.
EQ envelope options
- Open state file / Save state file - Opens/saves envelope states. Several different pre-defined state files are available.
- Copy state / Paste state - Use this to copy and paste envelopes, usually between instances of the EQ editor across open plugins.
- Undo - Undoes the last envelope edit.
- Undo history - Shows the editing history since the last reset.
- Flip vertically - Inverts the current envelope.
- Scale levels - Opens the Scale Level tool.
- Normalize levels - Scales the envelope so the highest and/or lowest levels reach +/- 100%.
- Decimate points - Opens a simple tool that allows manipulation of the number of control points in the envelope (useful in conjunction with Analyze audio file).
- Filter - Opens the Envelope Filter tool (useful in conjunction with Analyze audio file).
- Smooth up - Opens the Smooth Up tool that allows smoothing of the envelope shape (useful in conjunction with Analyze audio file).
- Smooth up abrupt changes - Quick removal of 'spikey' or sudden changes in the envelope.
- Turn all points smooth - Preset filter to quickly filter the envelope.
- Create sequence - Opens the Envelope Sequencer tool.
- Analyze audio file - Open, analyze and replicate the volume envelope of an input sound file. Drag and drop audio files directly on the Envelope editor for automatic analysis.
- Reset - Restore default settings.
- Accept - Process and paste (replace) the original selection.
