THD Meter ~ Measure Total Harmonic Distortion


MathAudio THD Meter VST/AU

  • Measures Total Harmonic Distortion (THD) in sound cards, speakers and headphones.
  • Applies matched filters for maximizing the signal-to-noise ratio (SNR) in the presence of additive stochastic noise.
  • Supports microphone calibration files.
  • Supports full range of sample rates from 44.056 kHz up to 384 kHz. All sample rates are supported without resampling to avoid any possible loss in accuracy.

Online Multichannel Peakmeter Using AudioWorklet


hydrogenaud.io/index.php/topic,126685

Digital Peak Programme Meter


Under-reads very short peaks slightly like a traditional BBC PPM. Fallback ballistics are accurately modelled but the attack time (eg the BBC spec of 2.5dB down for a 10ms burst of 5Khz) is only approximate. Very short peaks such as 1.5ms register -4dB instead of -9dB as per spec. The fallback time from 1 to 7 is in line with BBC specifications, 2.5 to 3 seconds. You may prefer a faster fallback, especially as there are the peak markers, so the fallback time can be adjusted by means of an arbitrary value entered on the options page. A value of 2 corresponds to the BBC PPM spec. Values up to 10 speed up the decay.

Mono matrix can be set to M = (A+B) – 3dB or 6dB. Traditionally the BBC have used M3, though M6 is increasingly used. Channels can be labelled L & R or A & B. Displays Left, Right, Mono (sum) and Stereo (difference) simultaneously.

The peak markers can be set to hold the peak. Click on the window to reset.

There is also a 20dB button. This increases the gain of of the Stereo difference indication  by 20dB (10 times). M, L & R are not affected.

The colour of each bar can be set to any colour from the options screen. By default all bars are green but it possible to have, for example, red and green for A and B.

For Windows XP, Vista, 7 or 8.

Digital Level Meter ~ 0.1 dB Resolution Readout


With 0.1dB resolution readout, ideal for accurate steady state measurements or for reading peaks however short.

For Windows XP, Vista, 7 or above.   Requires WDM drivers, does not support ASIO.

The button to the left of the readout switches the digital readout to follow the maximum peak markers or the instantaneous ‘live’ peaks. In conjunction with the peak hold feature this enables transient peaks to be read accurately.

Zero is referenced to Full Scale Digital, although this can be modified with the calibration adjustment to provide some headroom as required.

Sample rate can be set to match recording if necessary.

Infinite peak hold setting if required, even across program restarts. Reset by double-clicking meter display.

If you need to run multiple meters monitoring more than one source there is a Multi-Channel Level Meter for up to 24 channels.

Correlometer ~ Multi-band Correlation Meter


Correlometer is an analog-style stereo multi-band correlation meter.

Multi-band correlation meter is an advanced way to check for presence of out-of-phase elements in the mix. Broadband correlation metering reports overall phase issues and may misrepresent problems present in select spectral bands, while multi-band correlation meter easily highlights problems present in mid to high frequencies that are not easily heard by ear, but may still reduce clarity of the mix. Another application of multi-band correlation metering is phase- and time-aligning of channels and tracks, especially bass and bass-drum pairs, guitar mic and D.I. source pairs, two-microphone stereo recordings, etc.

Correlometer can display 4 to 64 individual spectral bands, with adjustable band quality factor that controls the degree of band’s selectivity. Averaging time of correlation estimator can be adjusted. Correlometer supports side-chain inputs for easy correlation estimation between separate audio tracks.

  • 4 to 64 band correlation meter.
  • Adjustable band quality factor.
  • Adjustable averaging time.
  • Side-chain input.
  • Resizable user interface.
  • All sample rates support.
  • Zero processing latency.
  • User interface color schemes.
  • Retina and High DPI support.

MonoChannel ~ EQ & VU Meter Plugin


MonoChannel is a EQ and VU meter with basic console channel controls.

Insert MonoChannel on your audio tracks to monitor your audio signal and adjust its tonal balance. It is designed only to encourage the use of proper gain staging and audio balance workflows in digital audio. MonoChannel is NOT a distortion/saturation/console emulation plugin.

  • Classic VU meter simulation
  • +/- 24dB of gain control
  • Smooth HP filter
  • 3-band tone shaping EQ

Windows Vista / 7 VU Meters


Windows VU Meter is a standalone application that mimics an old stereo’s VU or audio level meters. Designed for Microsoft® Windows Vista® and up (even tested on Windows 7®), the program has no intervening toolbars or window frames to allow the program to allow a clean interface and make it easy to overlay on top of a program you’re using. Features of the program include:

  • For Microsoft ® Windows Vista ®, and after testing, works with Windows 7 ® as well.
  • Clean interface that includes no toolbars or window dressings
  • Ability to select response time of VU Meter, selectable of 150ms or default 300ms. Response time is the amount of time it takes the needles to make a full swing of the gauge.
  • User selectable interface component coloring. Program saves and remembers settings the next time it’s run.
  • Option setting to allow always-on setting, allowing the program to be laid over another program that you’re monitoring the audio levels for. An example image.
  • User option to alter the maximum value of the VU Meter. This is handy for videos or music that were recorded at a lower value. The above example image is an example of this too.
  • All program options and commands are handled by right-clicking the interface.
