VUMeter

VUMeter is a useful tool designed to display the sound level from your playback or recording devices. It is an easy to use tool that can measure the sound output and display it on your desktop.
The VU meters are used on recording devices and other audio equipment both for esthetic purposes and to provide information about the audio input or output. It is useful when dealing with low sounds that are hard to notice in a noisy background.
Although a similar interface can be used for displaying other information, the Volume Unit Meter usually measures the level of the audio signal from a specified source. This tool allows you to select the source between all the input and output devices installed on your computer.
The interface of the VUMeter replicates the analog meters that are used on classic equipments and provides you with accurate readings. It requires no previous experience with audio recording devices since the only necessary configuration is to select the audio source.
You can also change the meter size and display it on top of other windows if you want to view the sound signal level while using other applications. The window can be resized freely between 50 and 200 percent in order fit it into your desktop layout.
During our tests, the program provided accurate measurement of the audio level and recognized all the playback devices available on the system. Unfortunately, it cannot run in multiple instances in order to measure the signal of multiple sources at the same time.
Overall, the VUMeter is a simple program that can be used by both casual users and professionals that need to visualize the audio signal.
