What is an SPF2 file

SPF2 files mostly belong to SpectraSuite. SPF2 files serve two distinct roles depending on their origin.
For files created by Ocean Optics, an SPF2 file is a Spectrum file designed to hold measurement data from a spectrometer. This internal format is used by SpectraSuite software for processing optical spectra and calibration data. More details can be found on the Ocean Optics website.
Other SPF2 files use JSON formatting to store preset settings for the Reveal Sound Spire synthesizer. In these cases, the file contains configuration data that defines sound parameters, and the JSON structure makes it somewhat human-readable with a text editor.

Spectrometer Data: Contains measurements, calibration, and spectral information.

Audio Preset Data: Stores synthesizer settings in a JSON structure.

FilExt.com note: Depending on the file's source, open it with the corresponding software to view and use its content.

How to open SPF2 files

You need a suitable software like SpectraSuite to open an SPF2 file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your SPF2 file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a SPF2 file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert SPF2 files:

SpectraSuite
See the previous paragraphs to learn more about the main application. SPF2 files are often referred to as SpectraSuite data files because this type of file is primarily created or used by this software.
SpectraSuite (Ocean Optics) and Reveal Sound Spire
The *.SPF2 file extension is primarily associated with two distinct file formats. The most prevalent format, representing 69% of observed *.SPF2 files, is the spectral data file used by Ocean Optics spectrometers. These files store measurements of light intensity as a function of wavelength, captured by the spectrometer. The data within these files is encoded in a proprietary binary format specific to Ocean Optics devices and software. Less commonly, the *.SPF2 extension is also used to denote preset files for the Reveal Sound Spire synthesizer, a software plugin used for music production. These presets, comprising 30% of encountered *.SPF2 files, are stored in the JSON format and contain configuration settings that define the synthesizer's sound, including oscillator parameters, filter settings, and modulation routings. This file format is classified as Data Files and Presets.

How to solve problems with SPF2 files

Associate the SPF2 file extension with the correct application.
Update your software that should actually open data files. Because only the current version supports the latest SPF2 file format. Search, therefore, e.g. on the manufacturer website after an available SpectraSuite update.
To make sure that your SPF2 file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
