If you're creating content for tv or web you will almost certainly run into different broadcast regulations that you need to adhere to.

Our groundbreaking Loudness Radar has for years helped users of Adobe Premiere keep their loudness in check.

What the Loudness Radar does is simply measure any audio track and show you the real terms levels of your work.

In a nutshell: the Radar is the tool you need to get a coherent and smooth output.

Why Measure Loudness?

Most broadcasters have to comply with very specific loudness standards in order to prevent systematic level jumps between sections. In particular, commercial breaks have caused many viewer complaints.

By measuring audio loudness, you make sure your content adheres to the standards relevant to your country or region.

It's the best way to ensure the client doesn't reject your project due to loudness issues - and for you to make sure your audio will sound its absolute best when aired.

Tried & True

For over a decade the technology behind the Loudness Radar has been an integral part of the workflow at some of the world's leading broadcast stations and post production houses.

In fact, our engineers have played a key role in the initial research of "perceived loudness", research that has laid the ground for the regulation of loudness across the globe - and across platforms.

The presets bundled with the Loudness Radar keeps your audio quality at its finest, and makes sure your content is being broadcast just the way you intended it to sound.

Why Adobe Chose Our Radar

"Loudness compliance is a key requirement for content creators today and moving forward. Our Adobe Premiere Pro and Adobe Audition users will be able to have access to an innovative and easy-to-use loudness monitoring solution."

Senior Director of Strategic Relations, Adobe

Next Generation Metering

Level control in digital audio has traditionally been based on simple peak measurement. This method doesn't take things like duration and frequencies into account - which is how we humans perceive sound.

We've poured 15 years of research into making a series of great loudness tools, that help you achieve exactly the sound you want and make sure it's reproduced as you intended it.

In the end it's all about picking the right tool for the job - whether it's for television, radio, youtube or podcast.

Tip 1: Loudness Radar speed

Set the time according to the length of your track - plus a little more.

Tip: If your track is 3:50 minutes long, set the radar time to 4 minutes.

Extend your measurement setup with a Clarity M hardware meter to always have the Radar available. 



Tip 2: Steady your track levels

Want to make the lead vocals equally loud throughout the song?

Tip: Use the short-term loudness history to make sure loudness is consistant from start to finish by metering the vocal track. 


Tip 3: Bring balance to your mix

Program Loudness can help you make a better balance of your mix.

When mixing music and speech together, a good loudness between the background music and the speech is 6 LU. This will keep the speech clear and intelligible while the background music retains its sonic weight.

Tip: First, make sure your tracks are loudness aligned (e.g. they have the same Program Loudness).

Then, use your track faders (including automation) to set the desired distance between the dB level of the tracks.


Tip 4: Make your mixing levels consistent


Many of us tend to unintentionally turn up the volume during the work day. While we start at moderate listening levels, we often end up playing quite loud.

Unintentionally, we add more gain to individual tracks or track group, either by altering the automation curves, or adding frequencies using our EQs.

Since your hearing changes when listening at different levels, mixing and mastering should at all times be done at consistent levels - simply to avoid inconsistencies in levels and spectral balance throughout the duration of your track.

You can use the Loudness Radar meter to help you stay a consistent listening level.

Tip: Insert the radar on your output bus - make sure to put it after any insert effects. Set the radar speed to 12 hours or how long your working day is. Make sure not to adjust the levels post DAW.

Extend your setup with the Clarity M hardware meter to always keep an eye of listening levels.


Tip 5: Compliant delivery

If you deliver your track to a broadcaster, there is a big chance that they have loudness requirements that you need to adhere to.

Tip: Use loudness measures such Program Loudness, True-peak Max or LRA to determine if your song is on par with local loudness requirements. Always check delivery standards before starting your work.


Tip 6: Use the momentary ring to determine micro dynamics

The momentary ring around the radar area reflects your momentary loudness - based on a 400 ms sliding window.

Momentary Loudness will reveal if your compressor is "pumping" or is set too aggressively.

Tip: Use the Momentary Loudness ring to judge how micro dynamic your track is. If it's jumping up and down rapidly, your track is very dynamic. If not, you need to be aware if you have used too much compression, for instance.

Extend your setup with the Clarity M hardware meter to always have the Momentary Loudness ring in sight.


Tip 7: Program Loudness

The Program Loudness - also known as Integrated Loudness - is a single number that describes the perceived loudness for the entire song.

Tip: If one song has a higher Program Loudness number, an average person will judge that song to be louder overall.


Tip 8: Optimize for different listening environments

The Loudness Range (LRA) descriptor shows the distance between soft and loud parts in your track - minus top and bottom values.

Tip: Use LRA to make sure your track is optimally mixed for playback - anywhere.

The loudness range that the ear can perceive very much depends on the listening environment. A quiet cinema with a powerful P.A. justifies a much higher loudness range compared to for instance in-flight entertainment.


Tip 9: Consistent loudness across a collection of tracks

If you do a collection of songs or audio clips, you'd most probably want all songs to be equally loud, and therefore you want all songs to end up at approximately the same loudness number.

Tip: Use the Program Loudness to determine the loudness balance between a series of songs.

It is of course an artistic choice whether you want your songs to be equally loud, but you can use Program Loudness to determine if they actually are.

Bonus tip: Perhaps you want to pick a great reference track to compare with.

Extend your setup with the LCn Loudness Correction suite to batch-adjust the Program Loudness of collections of tracks.


Tip 10: True peaks

The "Peak" indicator blinks if your tracks has true-peaks. The true-peak indication level can be set in the settings menu.

Tip for recording: To be sure there are no true-peaks in your recording.

During mic-check, set the peak level to -10 dBTP and make sure there are no peak-indications. This setting varies based on the type of source you record.

Tip for delivering music: You want Max-TP to be at the exact value you've determined. If you target non data-compressed file formats or data-compressed file formats where the encoding process is pre-determined, this should be 0 dBTP.

Tip for broadcast delivery: If you deliver to broadcasters, there is typically a Max-TP number that you need to comply to. This level is typically either -1 or -2 dBTP. Use the peak indicator to make sure you don't exceed to maximum TP-level

To get a set of professionally LED based True-peak meters with True-peak Max readout, extend your setup with the LMn Radar Meter or even the Clarity M hardware meter.
