Audio normalization

The normalization of the audio level is something that is achieved by applying a constant and maintained amount of gain, in volume, to an audio recording to bring the average peak amplitude to a desired level that has been previously defined. To which the same amount of gain is applied to the entire range, the signal-to-noise ratio generally does not change. Normalization differs from dynamic range compression, which applies different levels of gain to a recording so that the amplitude is within a minimum and maximum range. Standardization is one of the most common functions provided by a digital audio workstation.

Peak normalization

One type of normalization is peak normalization, in which the gain is changed to bring the highest PCM value or the highest peak of an analog signal to a given level.1

Since it only searches for the highest level, it does not take into account the apparent volume of the content. As such, peak normalization is generally used to change the volume in such a way as to ensure optimum use of the distribution medium in the mastering stage of a recording. loudness normalization.

Normalization of loudness

Another type of normalization is based on a loudness measure, in which the gain is changed to bring the average amplitude to an objective level. This average may be a simple measurement of average power, such as the RMS value, or it may be a measure of the loudness perceived by humans, such as that offered by ReplayGain.

Depending on the dynamic range of the content and the target level, the normalization of the loudness can lead to peaks that exceed the limits of the recording medium. Some software has the option of using dynamic range compression to avoid saturation when this happens. In this situation, the signal-to-noise ratio is altered.

Modern Audio Normalization

Currently Mp4Gain uses an audio normalizationn that is more similar to that used in modern recording studios or live music group recitals.

It is a normalization of volume focused from a new perspective.

Under this new paradigm, not only does it achieve that all songs have the gain of loudness at the best possible level, but it also achieves that each instrument and / or voice obtains a level of gain that makes it audible. Achieve an optimized level of volume gain normalization.

There is no other normalizer in the market that obtains this level of result. People with training in hearing listening can easily notice the difference., very similar to that obtained with expensive hardware in radio stations or in recording studios or in recital consoles, combining limiters, modern compressors and other processors.
All these results that offer expensive hardware equipment, Mp4Gain does for a few dollars.

In fact, the opposite result is achieved than that achieved with masking, because with masking, which is a method used to compress music, you can no longer perceive some sounds that are behind a more audible sound, that is what is called masking, which leads to the loss of audio quality.

Mp4Gain manages to highlight hidden instruments and sounds, performing an audio normalization by frequency bands to achieve this.

That is why we say that Mp4Gain achieves the same results as those obtained through a series of hardware equipment (limiters, compressors, normalizers, etc.) that are very expensive, while Mp4Gain costs only a few dollars.

Mp4Gain , the future is now

The headache is easy aber today and where it originated : was the encoder we use to make our music was not the same one used by others. Everyone use different encoders WAV to MP3 and also , I use different settings . Ie with a different bitrate and samplerate different , which originated in chaos. No sound the same , did not have the same volume level and therefore we had to manually move the volume knob reprouctor our digital music with each new song.

Indeed, even today we continue on the same problem . We continue with our music convirtindo essentially different encoders with different settings , we therefore we making the problem worse , the volume levels of our music does not match at all and THAT makes us suffer.

Well, we have briefly discussed the problem, now we need to note the solution.
Sure , we could save text and simply point out that the solution is Mp4Gain .
But explain not only what it does, which is basically equal the volume of our digital music and our videos ( in the most popular formats), but to explain why it works so well.

And it works so well, so efficiently, that analyzes and optimizes each of the millions of frames that make up a digital file. No measures the overall volume of a song or video, but does so in each of the millions of frames of this song or video and makes every frame obtained, at each frequency , the best possible level of volume.

By this sounds each instrument and each voice is like to be treated individually . Even after normalize the file , are more notorious instruments that went unnoticed.

All estoocurre thanks to modern mathematical algorithms, mathematical curves and dynamic , which can process, separate , distinguish and optimize digital audio as only Mp4Gain can.

You can download and try it on your Mp4Gain computaora with its own file, then decide adquirilo for a very low price when compared to the thousands of dollars they cost compressors, limiters, exciters and other equipment that achieve similar results in large recording studios , FM transmitters and television broadcasters.
