WFM Viewer

WFM Viewer is a lightweight audio application whose purpose is to help you analyze audio signal in time and frequency domains.

Portable running mode

This is a portable utility that brings several advantages to your system. You can bypass the installation process and run the program by simply opening the executable file.
In addition, you may copy it on any USB flash drives or other portable devices and uninstall it by deleting the files that you have grabbed from the Internet. It doesn’t store entries in your Windows registry and leave other configuration files in your system.

Importing options

WFM Viewer gives you the possibility to import audio files in the working environment by dragging and dropping the target file directly on the program’s executable icon.
A double-click on the executable file allows you to search for a song in your computer and import it in the main window. The utility works with WAV, WFM and WV file format.

Analyze audio files

WFM Viewer is able to automatically process an imported audio file, perform spectrum analysis, and reveal the time and frequency domains in the main panel.
The GUI looks intuitive and easy to work with but basic knowledge of FFT spectrum analysis is required in order to understand the program’s capabilities.
The tool gives you the possibility to zoom in or out of the generated analysis, increase or decrease DPI, set system DPI, rest the current view, as well as show or hide legend and annotation.
What’s more, you are allowed to copy the image to the clipboard so you can easily transfer data into other third-party utilities, export the photo to BMP, PNG or SVG file format, and view information about the current file, such as length, samples, sample rate, bits per sample, and channels.

Bottom line

All things considered, WFM Viewer integrates a bunch of useful tools for helping you perform detailed inspection of signal files in both time and frequency domains.
