An analog VU meter with peak LED. A volume unit (VU) meter or standard volume indicator (SVI) is a device displaying a representation of the signal level in audio equipment.. The original design was proposed in the 1940 IRE paper, A New Standard Volume Indicator and Reference Level, written by experts from CBS, NBC, and Bell Telephone Laboratories. [1]
Our favorite decibel apps include: Decibel Pro, Decibel X, NIOSH SLM app (for iPhone), and Sound Meter & Noise Detector (for Android) Apple products allow passive alerts to help prevent exceeding ...
Loudness monitoring of programme levels is needed in radio and television broadcasting, as well as in audio post production.Traditional methods of measuring signal levels, such as the peak programme meter and VU meter, do not give the subjectively valid measure of loudness that many would argue is needed to optimise the listening experience when changing channels or swapping disks.
Real-time graphic visuals, such as bar, waveform, spectrogram, spectrum, and VU meter. Basic and advanced effects and filters such as noise reduction, compressor/expander, volume shaping, volume matcher, pitch, reverb, resampling, and parametric EQ. Effect previewing; Saving and restoring effect presets; DirectX Audio plug-in support
This version adds a Device Toolbar to manage inputs and outputs, Timer Record and a Mixer Board view with per-track VU meters. Compared to the last 1.3.x release it is not a big improvement; the major version increment was chosen to signify a new stable version after many years of only beta releases. 1.3 November 28, 2005
Standard "skin" elements can be individually augmented or replaced with different dials and buttons, as well as visualizers such as waveform, oscilloscope, spectrum, spectrogram (waterfall), peak and smoothed VU meters, which all of them are analysis-oriented, at least for built-in visualizations. foobar2000 offers third-party user interface ...
A peak meter is a type of measuring instrument that visually indicates the instantaneous level of an audio signal that is passing through it (a sound level meter). In sound reproduction, the meter, whether peak or not, is usually meant to correspond to the perceived loudness of a particular signal. The term peak is used to denote the meter's ...
There are usually one or more VU or peak meters [a] to indicate the levels for each channel, for the master outputs and to indicate whether the console levels are clipping the signal. The sound engineer typically adjusts the gain of the input signals to get the strongest signal that can be obtained without causing clipping.
