6. Blue Cat’s DP Meter Pro

by Blue Cat Audio

Blue Cat's DP Meter Pro

Blue Cat’s DP Meter Pro (DPMP) is a unique audio analysis tool: it combines very flexible and customizable audio meters with advanced side chaining control capabilities thanks to its MIDI and automation outputs.

The metering capabilities of the DPMP plug-in let you control and monitor audio signals exactly the way you want: almost every aspect of the peak, RMS and crest factor meters can be customized. It proposes five different scales by default, including Bob Katz’s popular K-System scales (K-12, K-14, K-20), and you can create your own.

Large coloured statistics displays following your own scales are included for an overview of a track, while histograms give you a precise measurement of the dynamic range of the track. The graphs show the evolution of the audio envelopes over time, and the mid-side switch lets you verify mono compatibility problems and check the “stereoness” of your audio sources very easily. Whether you are working with mono, stereo or surround tracks, this plug-in will fit into your workflow.

All envelopes (peak, RMS, crest factor…) can be reused for additional monitoring or side chaining purposes: combined together, reversed, modified and recorded as automation curves or sent as MIDI CC messages, they can control other effects in real time.

The DP Meter Pro possibilities are endless, from voice over and ducking to side chain compression, multiple tracks monitoring or dynamic stereo enhancement. It is also possible to control external MIDI hardware (such a synths, MIDI effects), video effects or lighting systems with an audio signal.

Features

  • Multichannel peak, RMS & crest factor meter.
  • True dynamic range measurement with levels histograms.
  • Instant, average and maximum audio levels.
  • Modular user interface to fit into your workflow, with multiple screen sizes.
  • Total control over the metering characteristics, including attack/release shape.
  • Bob Katz’s K-System scales support (K-12 / K-14 / K-20 and custom)
  • Mono, stereo, mid-side or surround analysis.
  • Record measurements (peak, RMS, crest factor, clip etc.) as automation curves.
  • Control in real time any MIDI-compatible plug-in or external MIDI device with the generated envelopes thanks to the plugin’s MIDI CC output. See the Tutorials section for more examples.
  • Manage the shape of the output envelope: record reversed envelope, change amount of signal, and offset the generated envelope. This lets you use the plug-in for side chain ducking, compression and much more.
  • Easy ‘stereoness’ and phase cancelation measurement.

Blue Cat Audio Standards:

  • Native DSP code for optimal performance.
  • Full MIDI control and automation support with silent, zipper-free parameters update, advanced response control and MIDI Learn.

8. Blue Cat’s FreqAnalyst Pro

by Blue Cat Audio

Blue Cat's FreqAnalyst Pro

Blue Cat’s FreqAnalyst Pro is a real time spectrum analyzer with advanced functionalities. It uses the same smooth algorithms as its little brother (Blue Cat’s FreqAnalyst free plug-in): it has been designed to provide extreme smoothness and high resolution for both time and frequency. The frequency analysis can be fine tuned in details: manage its precision and rate, apply an offset or slope to the measured spectrum. Two thresholding systems are available, and the time response can be changed thanks to the attack and release parameters.

Three modes are offered for each channel: instant, peak or average response can be displayed on the same graph. Zooming capabilities and coordinates display let you exactly measure the characteristics of the spectrum. The four memory slots let you store any curve in memory: it helps you make comparisons between several tracks or effects setup very easily. A spectrogram view has been added so that you can monitor the evolution of the spectrum over time either in 2D or 3D (3D waterfall mode). All channels are of course available in this view, with exact coordinates display and zooming capabilities. Like many of our other professional analysis tools, this plug-in also provides output parameters that you can use to control other effects in real time: the generated automation envelopes or MIDI CC messages include the minimum and maximum frequencies and the energy center of the spectrum, expressed in Hertz or as MIDI note value.

With the transformation parameters (offset, amount and reverse), you can customize the generation of these parameters and monitor the modifications on the value graphs. Thanks to this unique functionality, you can now control any effect with the pitch of the audio signal: imagine a filter on an instrument controlled by the pitch of another instrument, compression depending on the pitch of the signal… Anything is possible. Thanks to Blue Cat’s skinning language support and the included window opacity management feature, you can adapt the plug-in user interface to your personal needs and enhance your workflow. For integrated multiple tracks spectrum analysis, check our Blue Cat’s FreqAnalyst Multi plug-in.

9. spiral

by Photosounder

spiral

Spiral is a music analysis plugin. It’s a fresh take on spectral analysis focused on allowing you to see and understand music and the notes that make it up instantly. This is achieved mainly by coiling the spectrum into a spiral framed by a chromatic circle, thus allowing you to instantly see what’s happening musically and spectrally. Several other factors help you see better what you’re listening to:

Features

  • The colours represent position in the stereo mix which means that quite often instruments have their own colour.
  • Portions of the sound can be recorded in Spiral’s memory and then played back at a much slower rate (between 0% and 100%). This is quite necessary and handy when writing down notes or analysing chords.
  • Analysis resolution can be adjusted. You’ll want to lower it when analysis notes played very fast as it gives you more precision in time, and increase it when analysing complex chords, bass instruments or when tuning an instrument.
  • The spiral visualisation can be rotated so that you may have the root of the scale on top and thus be able to recognise notes more readily.
  • By clicking on the visualisation you can create overlays that represent the harmonics for a given note. Adjusting those overlays can greatly help you in identifying the individual notes that make up a chord.

10. Buchla 296e Spectral Processor

by Softube

Buchla 296e Spectral Processor

This product is an expansion for Softube Modular. If you do not currently own Modular, you can purchase it HERE.

High-end spectral filtering and processing

Scratch the surface of any synthesizer, and you’ll find the heritage of a few great brands. Buchla has been responsible for some of the most innovative, creative, and sonically spectacular electronic musical equipment ever made, and we’re proud to have such a legendary name in our Modular system. In addition to our previously released 259e Twisted Waveform Generator, take advantage of the myriad spectral processing capabilities of the big friendly filter bank; the new 296e Spectral Processor; the only software version of this module officially licensed by Buchla U.S.A.

The real thing

Our Buchla 296e module is officially licensed and endorsed by Buchla U.S.A. It’s not just a copy, or a homage. It’s the real thing.

Programmable graphic EQ

There’s a lot you can do with 16 bands, each tuned to the discrimination curve of the human ear. Especially with external incoming CV, this module can perform complex sonic wonders.

Performs detailed spectral transfer functions

Spectral analysis and resynthesis opens up vocoding possibilities, using one module or chaining two together.

Rare and exclusive

The 296e is one of the most expensive and exclusive hardware synth modules in the world, and for very good reason. Its complexity, versatility, and sheer quality make it legendary.

Sculpt any sound with this ultimately programmable 16-band graphic EQ. Morph between two separate modulatable response curves. Control the individual levels of each band through external incoming CV or use the internal spectral transfer (vocoding) to link the envelopes of odd and even bands with their VCAs (and vice versa). And use the “freeze” function (as a toggle-button, or externally controlled by CV) to sample and hold these values (envelope times, A levels, or B levels).

The 296e Spectral Processor is capable of a startling variety of effects, wonderful world-building from mere white noise, or the separation of musical inputs into any elemental collection of individual parts, to be reused and reimagined at will.

Ear-pleasing vocoder

The center frequency of each band is pre-selected to complement the human ear’s discrimination curve, with the result that each one sounds meaningfully unique and pleasing. Its capability for intricate transformations allow it to be a real time performance filter, a programmable compound equalizer, and even a spectrum transferring vocoder.

16 band-pass filters are available, each with its own VCA on input, and envelope follower on output. They can be divided into two collections of eight, odd and even. In hardware this function can be used to split the module for use as a limited vocoder, with eight bands performing analysis and eight performing resynthesis. But of course, in software you can affordably run a pair of 296e modules side-by-side, for a full 16-band spectral transfer vocoding experience. The user can adjust envelope decay times, and pre-emphasis may be applied to smooth the frequency response for even more malleable vocoding.

Special MIDI function

A special addition in our software version of the module is the ability to ‘play’ the individual filter bands using MIDI. Note values attach to the different fixed filter frequencies, while MIDI velocity data affects the amplitude value of a given band’s VCA.

Add to this the wealth of great-sounding combination options available at a single click in Softube Modular, and the Buchla 296e turns an already attractive ecosystem into a truly expansive spectrum.

Features

  • Officially licensed and endorsed by Buchla U.S.A. – the only such emulation of this rare and exclusive module.
  • 16 band-pass filters, each with its own VCA and envelope follower.
  • Separate envelope decay times for each band.
  • Programmable graphic EQ.
  • Real time performance filter.
  • Morph between ‘A’ and ‘B’ level settings.
  • Performs complex spectral transfer functions.
  • Special new feature allows for ‘playing’ the filters with MIDI.
  • Use as a vocoder, split into two banks of eight, or using two modules at once for full 16-band operation.
  • Externally controllable “freeze” function stores the input spectrum as envelope values, or A and B levels, in the module’s memory.
  • Multiband extraction of envelopes from audio inputs.

System Requirements

  • Mac OS X 10.12 or newer (older OS versions may work but are not tested (64-bit only).
  • Windows 64-bit, versions 7, 8 or 10 (64-bit only).
  • Intel Core 2 Duo, AMD Athlon 64 X2 or newer.
  • Screen resolution 1280×800 or larger.
  • Supported sample rates: 44.1, 48, 88.2, 96, 176.4 and 192 kHz, in both mono and stereo.
  • 8 GB RAM or more is recommended, as well as at least 8 GB hard disk space for installation (individual plug-ins take less space, while sample libraries may require additional disk space).
  • A Softube account is required to register and install the software.
  • An iLok account is required for authorisation of the software.
  • Internet access for downloading installer and managing licenses.
  • iLok generation 2 and up, if you intend to use a physical iLok dongle for authorizing your plug-ins (note that an iLok dongle is not a requirement).
  • In theory, any 64-bit VST, VST3, AU, or AAX (11.0.2 or higher) compatible host application should work.
  • The most recent maintenance release of the DAW application is recommended.

However, due to plug-in host differences between DAWs – and our own rigorous testing standards – we only officially test our plug-ins and instruments in the most recent versions of Pro Tools, Logic Pro, Cubase, Live, Studio One, Digital Performer, Reaper and Sonar. Softube plugins are not tested in the non-listed systems, but they most likely work as long as the system requirements are met. We cannot guarantee a solution for issues in unsupported systems.

  • Softube Modular is required to run this software.
  • Make sure that you always use the latest iLok License Manager. It is not included in the Softube installer but can be downloaded from www.ilok.com​
