Added loudness optimization option for YouTube

Estimated Weighting Curve Used for YouTube Loudness Normalization

In accordance with YouTube 's loudness normalization specification, an option to optimize sound pressure has been added to AI Mastering's custom mastering.

"Target sound pressure mode" option

Specify the reference calculation method of the target sound pressure.

target loudness mode option

Loudness (conventional operation)

Limits the loudness defined by ITU-R BS.1770 to match the target sound pressure. It is the same behavior as before.

YouTube Loudness

Limits the approximate loudness value used in YouTube loudness normalization to match the target sound pressure. The approximate calculation formula was created based on a study of YouTube's loudness normalization algorithm .

According to the survey, since the reference value of the loudness normalization is -10.3 dB, considering that the actual sound pressure slightly decreases from the target sound pressure, if the target sound pressure is set to about -9 dB, the loudness normalization does not work or it does not work You can set it to the very last sound pressure.

How to optimize loudness for YouTube?

If you master with the settings below, including the "Ceiling" option added here , you can perform mastering optimized for YouTube.

"Target sound pressure mode": "YouTube loudness"

"Target sound pressure": "-9 dB"

"Ceiling mode": "True Peak (15 kHz Lowpass)"

"Ceiling": "-0.5 dB"

※ The YouTube loudness normalization reference value is -10.3 dB and the target sound pressure is -9 dB because the actual sound pressure slightly drops from the target sound pressure.

How to make it operate like a conventional one?

If you make the following settings, the conventional operation will be performed.

"Target sound pressure standard": "Loudness"

AI Mastering has been updated

AI Mastering has been updated.

I lost the one-touch mastering setting

In order to make it easy to use AI Mastering, I lost the one touch mastering setting. Please use custom masting when you use the option to save bass and use movie title option.

Target sound pressure of one touch mastering has been lowered

We reduced the target sound pressure of one touch mastering to -9 dB so that you can master safely in a wide range of applications such as YouTube videos.

Those who ask for high sound pressure please use custom mastering.

We deleted less frequently used functions

Delete "Depth plus" function and "Lift up" function. Please let me know if you need to revive.

Integrated preset mastering into custom mastering

To simplify the UI, we integrated preset mastering into custom mastering.

Added "YouTube Loudness Correction" indicator

The "YouTube Loudness Correction" metric is an estimate of how much loudness is compensated by loudness normalization when uploading to YouTube.

When uploading to YouTube it is good to avoid this value becoming too small.

This calculation is based on the results of this survey .

Added "True peak" indicator

The "True Peak" index is the inter sample peak.

The "True peak (15 kHz low pass)" index is the inter sample peak of the waveform after applying a low pass filter of 15 kHz.

On some video platforms such as YouTube, uploaded videos are re-encoded. At that time the waveform changes. The big influence is the low pass filter applied when re-encoding.

According to this , the cutoff frequency of the low pass filter applied in YouTube re-encoding is 15.1kHz, 15.8kHz, 18kHz, 20kHz.

If the "True peak (15 kHz low pass)" index is less than 0 dBFS, there is less chance of clipping when uploading to YouTube.

I made it possible to have a head room at the peak

Until now, the peak of the sound source after mastering was adjusted to 0 dBFS, but it is easy to clip when re-encoding the sound source.

It was more convenient to handle the sound source without worrying about clipping, so I made it a little room for the peak. Specifically, we set "True peak (15 kHz low pass)" to be less than -0.5 dBFS.

What is Shazam? - Apps that can search for songs

We introduce the application "Shazam" that can search for songs.

What is Shazam?

It is an application that can search for songs with the sound picked up from the microphone.

Install Shazam

You can install from the link below.


How to use Shazam

When you start Shazam, you will see the following screen.


Tap the middle button to display the screen below, pick up the sound from the microphone and search for songs.

Shazam Detect

Wait a while and the song will be identified.

This is the basic usage. Alternatively, you can tap My Shazam to see the history of songs you searched in the past.

Shazam's principle

According to the following, Shazam seems to be implemented with the technology called Acoustic fingerprint.

How to use Equalizer APO

We will show you how to use Equalizer APO.

Equalizer APO is Windows software that can apply audio processing to all sounds played on PC . For audio processing, you can use volume, equalizer, convolution of IR (impulse response), VST and so on.

Install Equalizer APO

If you are using 64bit Windows, please download the 64bit version from the link below and install it.

Equalizer APO

If you are using 32-bit Windows, please download the 32-bit version from the link below.

Equalizer with Equalizer APO

Equalizer can be applied in the arrow part of the screen below.

Change the volume with Equalizer APO

You can adjust the gain with the arrows on the screen below. Even if you just cut it with an equalizer, the waveform will change and the peak will pop out so it may be better to lower the gain to prevent clipping.

Use VST with Equalizer APO

To prevent clipping, try inserting the limiter at the end of the Equalizer APO.

Click the plus icon. Please choose Plugins / VST plugin.

equalizer apo add vst

The VST container was added at the very end of the process.

How to Japaneseize Equalizer APO

The following articles show you how to translate Equalizer APO into Japanese.

How to Japaneseize Equalizer APO

Possibility of Equalizer APO

Equalizer APO can be used in various ways.

Because the sound of YouTube movie is so loud that it cuts out high, or because there are many variations in the sound of YouTube movies so normalize it, because the dynamic range of the movie is too big to listen at home so compressing, speaker frequency characteristic correction And distance correction and so on.

Equalizer APO has made it possible to receive the benefits of VST not only for music producers but also gamers and YouTube viewers .


We introduced how to use Equalizer APO.

Actually, Equalizer APO taught foreign users that we use ITDPanner VST of our company for speaker correction. Please let me know if you want this VST!

Decide playlist reward

Choon has a function to create playlists. "Playlist Split" is the proportion of remuneration divided into playlist creators when a song is played through a playlist. If you want rewards, you should consider a smaller value, if you want to increase the number of playback, I think that a larger value is better.

Enter compensation distribution information

Choon has the function of automatically distributing rewards among people when multiple people ("Collaborator") are involved in sound source production. Please enter the compensation distribution information from the Contract tab. In the case of one person, it is OK as default.


Save it and you're done.
