AccessibleSpectrumAnalyser is a real time spectrum analysis plug-in that allows visual impaired users to as the accessible peak meter. Instead of monitoring the amplitude of the audio signal though, you will be monitoring the frequency components of the signal within a customizable selection of frequencies.
The plug-in uses the “clipping” sonification of the AccessiblePeakMeter. That is, you can set a threshold in dB and, as soon as the energy of any frequency in the selection goes past the threshold, you will hear a short beep. Like in the AccessiblePeakMeter, the beep starts at 440 Hz and it’s raised one semitone for each dB of difference between the frequency magnitude and the threshold. In case more than one frequency within the selection is higher than the threshold, then the highest one is taken into account for the sonification purpose.
There is only one single spectrum for both left and right channels: the two channels are mixed together before being analysed. In AccessiblePeakMeter, there is a separate sonification for peaks in the left and the right audio channel. In the AccessibleSpectrumAnalyser instead, one single sonification is panned from left to right and the panning represents the position of the peaking frequency in the whole spectrum, ranging from 20 Hz on the very left, to 20050 Hz on the very right. For example, if the selected spectrum peaks at 50 Hz then you’ll hear the beep towards the left, whereas if the peak is at 20 kHz the beep will occur towards the right.
Accessible Peak Meter uses real-time sonification to deliver information to the user about audio levels and peaks in audio signals, and so supports core activities in audio production. Accessible Peak Meter 3 is an extended development of Accessible Peak Meter. It adds more meter modes (RMS, EBU, VU/PPM, Truepeak, Dialnorm and Dynamic Range).
Accessible Peak Meter was developed in 2014/2015 at Queen Mary University of London as part of the Design Patterns for Inclusive Collaboration research project ( depic.eecs.qmul.ac.uk ).
USAGE The plug-in comes with the following tweakable parameters:
Sonification Type: to switch between continuous mode , clipping mode and clip tone mode. “Clip tone” sonficates as soon level is above threshold .
Dry: controls the level of the input audio, namely the audio content you want to analyze;
Wet: controls the level of the sonification;
Tone: controls height of the sonification tone in clip tone mode;
Threshold: sets the threshold for the clipping mode, it has no effect on the continous mode
Decay: this only affects the continuous mode sonification. The value ranges from 1 second down to 0.05 seconds. This is the time the meter would take to decay from 0 db to -inf after an impulse. These numbers don’t give a real feeling of how the sonification will sound – it is easier to think that when set to 0.05 the sonification will stop pretty immediately when you stop the audio; whereas if the value is set to 1, it will take longer to decay. In general, though, the latter sounds cleaner and normally the audio level doesn’t go all the way down to silence, as during the decay it encounters other peaks that bring it back up. So it’s up to you to find the right trade off.
DAW sync: if set to “on”, meter reset is synced with DAW start playing. Only applicable for program loudness modes like RMS/EBU/DialNorm IL and PLR
Meter Mode: sets the meter modes. Please to note that all meter modes are calibrated to 0 dBFS, 0 dBTP, 0 LUFS, 0LKFS, 0 VUFS and 0 PPMFS
The AccessiblePeakMeter3 provides access to the parameters by exposing them to inspectors – such as ReaAccess plug-in or the Cakewalk Sonar inspector – in a clear and well formatted way.
GSat+ is derived from the saturation module on the TBProAudio CS5501V2 channel strip plug-in, but adds extra features requested and suggested by the Gearspace.com team. It has several different saturation modes, high tweakability, oversampling, old-school VU meters and cross-platform software compatibility – as well as a button to take you directly to Gearspace.com in case you need any tips, tricks or inspiration or want to swap presets with other users.
Features:
Saturation with three different “tube-based” character modes
dpMeter is a precise digital audio multi channel meter including RMS, EBU R 128, Dialog gated and TruePeak (intersample) measurement. It is the successor of the very popular dpMeter4 and adds GUI resizing and preset management.
DR14 T.meter is a free and open source command line tool for computing the Dynamic Range of your music according to the procedure used in the off-line meter released by the Pleasurize Music Foundation.
This tool is a very useful measure of how loud your music is, and for understanding that a good quality album always has a wide dynamic range, and it’s also useful for understanding the effects of the so called ‘loudness war’.
Dr14 t.meter is released under the terms of the GNU GPLv3 license and is intended for the Linux users who can not use the Windows application released by the Pleasurize Music Foundation, or the plugin for Foobar2000.
I’ve largely tested this application and it has always returned results identical to those of the official off-line meter.
MAnalyzer is an advanced spectral analyzer and sonogram containing unique features such as smoothing, normalization, super-resolution, prefiltering and deharmonization. The included meters provide a peak meter and EBU R128 and ITU-R BS 1770-3 compliant loudness meter.
The Sonalksis FreeG is everything you need in a master fader. A simple, but absolutely indispensable plug-in, FreeG extends the functionality of a typical audio host by providing a large-format style fader, along with ultra accurate metering. FreeG helps to maximise workflow with extended, customizable metering, and multiple control features and settings.
When working with digital audio, a lack of fine metering and extended signal flow control in the host is a common issue. FreeG helps to improve workflow in the host by providing these features in the insert chain. By delivering enhanced control of amplitude, phase and pan (stereo version) in the insert chain as well as fine metering, with user configurable industry standard ballistic options, the freeG is the perfect master control.
Features:
Long-throw fader
Ultra accurate metering
Multiple metering ballistic types
Peak and RMS readouts
Pre/Post metering options
Selectable Pan-Law
‘Fine’ mode for sensitive calibration of the master fader
mvMeter2 is a multivariable meter including RMS, EBUR128, VU and PPM measurement. mvMeter2 is the successor of mvMeter and adds single/dual meter display, adjustable reference level for all meter modes, adjustable meter delay and preset management.
Features:
behavior of classic analog VU and PPM meters
multiple measurement modes: PEAK, RMS, EBU R128, VU and PPM
multi channel metering: stereo, left, right, mid, side
