What is an SRF file?

An SRF file is a data file created by Rational Acoustics Smaart, a program used by audio technicians and engineers to measure and analyze the acoustics of an environment. It contains a static "snapshot" of live spectrum measurements, which consist of a measurement signal (the output from a device) and an input signal used for reference. SRF files also store spectrum settings, such as the frequency scale of the graph, slice height of the spectrograph, and RTA display settings.

Spectrum measurements allow users to analyze one or more input channels. The measurements are displayed as a graph in real-time. These graphs can be captured by selecting Capture or Capture All in the Data bar in the "Spectrum" view. Captured spectrum measurements are saved in the SRF file.

By default, SRF files are placed in the following directory:

Documents\Smaart v8\Traces\Spectrum\Session Data

You can move them from this location. However, the spectrum measurements stored in the SRF files that are moved will no longer be displayed in Smaart.

Rational Acoustics Smaart enables audio technicians to analyze sound systems and diagnose problems. It is used in a variety of venues, such as stadiums, concert halls, and churches. The name of the program is an acronym, which stands for System Measurement Acoustic Analysis Real-time Tool (SMAART).

NOTE: SRF files were introduced with version 8 of Smaart and replaced REF files used by earlier versions of Smaart.

What is an SRF file?

An SRF file contains a vehicle avatar image that is used to represent the vehicle on the screen of various Garmin GPS devices. It stores multiple bitmap images that make up a 3D avatar and includes image data for various perspectives of the vehicle, such as the 3D and overhead perspectives. SRF files may be created by Garmin or by a Garmin GPS user to share with other users.

More Information

You will most likely only encounter an SRF vehicle avatar file if you use a Garmin Nuvi GPS device for navigation purposes and are looking to alter the vehicle that appears on the screen of the device. Various websites allow users to share custom SRF vehicle avatars, with some SRF files containing images of real vehicles and others storing fictional vehicle images, such as the Tron light cycle, Star Wars BB-8 droid, and Breaking Bad camper.

Most users that encounter an SRF vehicle avatar file have downloaded it from a website compressed in a .ZIP archive. If this is how you acquired the file, you can use the Zip utility bundled with Windows (Microsoft File Explorer) or macOS (Apple Archive Utility) to extract the image.

You can use the Garmin software packaged with the GPS device to open the SRF vehicle image to view it and import it to the /Garmin/Vehicle/ folder on your Garmin GPS device. You can also use Garmin Express to import SRF files to your GPS device.

There are various user-made programs that can convert SRF images to other image formats. The "nüvi utilities" online program can convert SRF images to .PNG format or PNG images to SRF format.
