I'm currently using a combination of free metering plugins to analyse my audio.
I want to streamline this process and have more/better functionalities in one plugin.

Can you recommend a quality metering suite ?
Please do not include Insight 2 and Tonal Balance 3 from Izotope as I prefer not to use Native Instruments related plugins.

Thanks for helping !

Edit :
After reviewing members recommendations I updated my current setup which is 100% free.
I'm still trying various complete metering suites.

Loudness
Youlean - Loudness Meter (Free)

Spectrum
TDR - Prism (Free)

Metric AB will always be my preference. But there is also IK MM Metering and Flux Analyzer.

 

Hello @OffshoreBanking;

Process.Audio Decibel - 30 Days test - 139 €

Bro you should try out Goodhertz loudness, its free and it has all the metering info you could ever hope for, since using it i haven't even searched for a better one or a paid plugin. With the missing oscilloscope or the spectrum I'd go for the minimeters plugins which work separate from the daw but can be connected via an audio server in the master channel.

 

FX23 - Psyscope
Mercurial Tones - Scepter
dsp-dealer - Inspect

Excite audio - VISION 4X

 

FLUX Mira

I liked Izotopes Insight for a while.
ATM the stock analyzer of Cubendo is sufficient for my needs.
//Edit//
Oh my bad... Didn't read properly... But have you checked what your DAW offers nowadays? I didn't know for years that they integrated everything I needed l.
BTW I'm so with you not to use NI.
The Nugen stuff is good too.

I use Insight 2 because they gave it away for free some months back as a promotion. I'd never pay the MSRP because $200+ for an analyzer is a bit much for regular audio production and mixing stages. but when you include it's interconnectivity with all your channels using the Relay plugin, it's pretty hard to beat. Finding a k'd version is not all that difficult.

I would probably switch to Nugen Visualizer, if not for the free copy of Insight 2. For the other plugins you are using, I'd get Oszillos Mega Scope and call it a day. I remember you mentioning making some electronic music genres? So yeah, Mega Scope would be my pick if you are going to buy one of these.

 

An Izotope free product vs Nugen super high prices....
Metric ADPTR is hard to beat anyway. I have Insight 2 and hawkeye. Hawkeye is outdated, at least visually. Insight 2 is fine but ADPTR does it all. Comparative too.

I'm still amazed at how Nugen prices seem high.

Tokyo dawn Prism is free and only mesures spectrum but it is one of my favorite.

Splitting functions in several dedicated plugins like you did is a great idea too.

I'd go Prism for spectrum, Bx-meter for Loudness, and Voxengo correlometer for multiband correlation. 2 of them are free, the third is cheap.

 

DMG Audio dualism is top notch imo....Track meter might be enought for your needs though...Flux audio has all in one meter/analizer too, and Nugen audio as well...
My go to is dualism
Saw that Baxter mentioned flux already nvm...OGs are the best

 

There's that VPS Scope thing, maybe it can replace basic scope, spectrum and stereo metering.

 

Okay, but aren't these 2 plugins related to NI?

 

Cubase Supervision

 

All the above are good choices but it's up to you. Choose what suits you Minimeters is quite powerful also and it works as standalone outside your DAW. It has all the modules you need in one or any individual modules you desire as standalone(VU/Waveform/Spectrogram/Spectrum/Oscilloscope/Loudness/Stereogram)

SSL Meter seems to be popular too.

 

You should consider the option of using sidechain or importing WAV files (for example) to compare with external sources, or the multichannel option. This way you can compare two or more sources at once.

DSP Dealer - Inspect --> Can edit themes/colours

 

Miss RME DigiCheck tbh, AnSpec kinda fills the void and guess topic isn't about all things metering, but SpecTrend is another useful freebie.

 

@Sinus Well Thanks for clarifying the ownership of Metric AB and SPL Hawkeye by Native Instruments.
@scoldt I replaced Live stock spectrum with TDR - Prism, it's better and free so that's really a no-brainer, thanks for the tip !
@Somnambulist SSL - Meter added to the classic option, thanks.
@ZUK Thanks for telling me about the color editing option in DSP Dealer - Inspect.

@Melodic Reality can RME - DigiCheck be purchased by people that don't have a RME interface or is it only available (for free) for RME owners ?

It's free, but It won't work without interface.
