Spectrum Analyser

Many operations that rely on a certain degree of accuracy or measurement is done with the help of a computer. Sound capturing, and processing makes no exception, and even Windows puts a default recording tool at your disposal. However, if you’re interested in thorough analysis, then Spectrum Analyser is sure to help you achieve this in real time.

The application comes with several advantages, and one of them is the lack of an installer, meaning you can carry it around on a USB flash drive to try out its capabilities on other computers as well. The target PC’s health status is not affected, because system registries are not a dependency, thus not modified.

One of the main requirements is a microphone, because the application’s core function is to analyze the audio signal it detects through such a detected device. However, a close management of the default audio driver makes it possible to be used with speaker sound, without having to connect a device.

Spectrum Analyser comes with a simple interface that might leave you scratching your head for a little while, or at least there’s some sound captured by the input device. However, the application doesn’t start monitoring unless you press start, moment in which the workspace starts being filled with wavelength display of incoming sound.

Sound is analyzed through a graph, with the possibility to set vertical and horizontal scale views, with several magnification levels. Decibels are shown in a slider below, with a clip indicator to alert you when sound is too loud to comprehend. Unfortunately, all analysis is done in real time, with no option to record, or at least capture video of the spectrum for further analysis later on.

On an ending note, audio processing is not an easy task, and there are a lot of small utilities required for proper output quality. One of them is related to the amount of generated noise, and Spectrum Analyser lives up to expectations by putting an intuitive workspace at your disposal, where audio signal can be read in real time.
