Accessible Peak Meter ~ Realtime Sonification

Posted by tom2tec on

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 ).

More information about Accessible Peak Meter can be found at depic.eecs.qmul.ac.uk/apm

USAGE
The plug-in comes with the following tweakable parameters:

  1. Sonification Type: to switch between continuous mode , clipping mode and clip tone mode. “Clip tone” sonficates as soon level is above threshold .
  2. Dry: controls the level of the input audio, namely the audio content you want to analyze;
  3. Wet: controls the level of the sonification;
  4. Tone: controls height of the sonification tone in clip tone mode;
  5. Threshold: sets the threshold for the clipping mode, it has no effect on the continous mode
  6. 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.
  7. 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
  8. 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
    1. Peak: same as AccessiblePeakMeter, dBFS
    2. TruePeak: based on ITU BS1770.4, dBTP  
    3. VU: peak meter, 300ms integration time, VUFS
    4. PPM: peak meter, target, PPMFS
    5. RMS: 600ms integration time, AES-17, dBFS 
    6. EBU: EBU R128, target level -23 LUFS, LUFS
    7. DialNorm: gated, target level -24 LKFS, LKFS
    8. DR: PLR/PSR, dB

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.

DR14 T.meter ~ Linux Dynamic Range Meter

Posted by tom2tec on

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.

Feature:
  • Compute the DR dynamic range of the audio file

RoughRider 3 ~ Dynamics Compressor VST

Posted by tom2tec on

Our RoughRider compressor is one of the most popular dynamics processors on the planet, with well over a half a million downloads over its decade-plus lifespan, and is in heavy daily use by producers the world over. With RoughRider 3, we’ve expanded the original to include an external sidechain input, the ability to turn off the built-in “warming” filter (the FULL BANDWIDTH button), and much more accurate metering.

foo_dynamic_range ~ Foobar & Dynamic Range Meter

Posted by tom2tec on

Dynamic Range Meter is a foobar2000 component designed to give the same information as the Dynamic Range Offline Meter. This component can process all audio formats foobar2000 can handle (a.o. flac, ape and wavpack) and also supports higher sample rates and bit depth. Using the Open Audio CD option it can also directly read audio CDs and calculate the Dynamic Range values without the need of ripping the CD to disk. Log information with extended statistics is automatically copied to the clipboard and can be pasted back in any text editor. ~ web.archive.org/web/20130317013715/http://pleasurizemusic.com/free-downloads

Dynamic Range Meter is a foobar2000 component designed to give the same information as the Dynamic Range Offline Meter from the Pleasurize Music Foundation. I wrote this component because the original Dynamic Range Meter is limited to reading only wav, aiff and mp3 files. This component can process all audio formats foobar2000 can handle (a.o. flac, ape and wavpack) and also supports higher sample rates and bit depth. Using the Open Audio CD option it can also directly read audio CDs and calculate the Dynamic Range values without the need of ripping the CD to disk. As an option, a log file with information and extended statistics can be saved to disk. ~ web.archive.org/web/20130428024316/http://www.jokhan.demon.nl/DynamicRange/

Warning: This component is known to be problematic, due to repeated crash reports, and should be installed with caution. ~ wiki.hydrogenaud.io/index.php?title=Foobar2000:Components/Dynamic_Range_Meter_(foo_dynamic_range)

  1. Install the foo_dynamic_range component
  2. Navigate to File > Preferences > Advanced > Tools > Dynamic Range Meter
  3. Enable “Write DR meta data tags“
  4. Add a new toolbar button and assign Context>Dynamic Range Meter
  5. Download DR toolbar icon and change button icon
  6. Navigate to File > Preferences > Display > Default User Interface > Playlist View
  7. Add a new custom column, name it “DR” and assign this pattern, “[%DYNAMIC RANGE%]“
  8. Select an album and click the new DR toolbar icon to scan the files
