Effects
Recorte features 25+ audio effects. These effects can be applied to the entire file, all regions, specific regions, or the waveform selection destructively (through the Apply actions) or non-destructively (through the Effect Chain panel in the Editor).
Effect Chains
The effect chains in Recorte let the user add effects to the active file non-destructively through a serial chain of effects. The chain is used when playing or creating files and regions (as new files in Recorte or exported audio files).
Effects can be added to the list through the () button. Reorder them by dragging and dropping on the effect title.
Each effect in the list can also be collapsed (▸), disabled () or removed () using the buttons on the effect header.
Each file loaded in Recorte contains two effect chain types:
- Global: A single global chain in the file that is applied to the file (including all regions).
- Region: Individual effect chains that can be added to each region.
Applying Effect Chains
Effect chains can also be applied (destructively) to an entire file, its regions, or a selection using the Apply Effect Chains action.
Effect Chain Presets
Effect chains can be saved and loaded as presets from the Effect Chain sub-menu () in the section header.
It is also possible to replace the default effects. Overwrite the default.json preset file or select the Save as Default option from the preset sub-menu.
Presets are stored as JSON files and can be used in any file.
Managing Effect Chains
The Effect Chain sub-menu () also contains options for copying, pasting and clearing the effect chains.
