Spectro

Spectro is designed to be a VST plugin for any compatible host, offering the possibility of spectral editing in real-time. The range of features can be used for both common tasks to increase or decrease volume in specific parts of an audio file, as well as advanced management to remove noise or combine filters for different effects.

Audio input is automatically analyzed, with the wave representation showing up in the main window. Editing is done by dragging boxes around parts of interest, while navigation throughout the whole project is based on a timeline. The mouse can be used to zoom in and out for more viewing space.

The selection box holds several control buttons with which to mute, make solo, bypass, or delete the specific region. It can be moved in real time for other areas to be modified on the spot. This can be done with multiple selection boxes in order to combine and create nesting regions. Two additional knobs provide options to apply gain, or fade effects.

The navigation timeline is split into several regions, depending on the size of the general wave preview area. Clicking a specific region places focus there in the general preview. This can be used to cycle to areas of interest. All changes can be saved or discarded at the press of a button, with an additional option for loop detection.

All editing depends on management of regions. Multiple selection boxes can be created on the same region. Combining them results in the creation of different effects. These can be moved around, copied, or removed.

Visual customization options can be used to change the default display of the main window. Brightness is adjusted through a dedicated knob, with a reset button that reverts all changes to the default configuration. Colors are also subject to change, with a built-in colormap to cycle through different styles for the spectrogram representation.
