This situation, which does not apply to every platform, is a feature developed for us to hear sounds in a healthy and natural way.

So how does this feature actually work?

When we increase the face of the videos, there are valuable techniques behind the sounds of the sounds not to take.

These techniques are the time stretching and curtain shift used in the digital signal process. These techniques that keep the curtain constant while changing the face of the sound reveal a natural and understandable sound.

If we take a closer look, what is this time stretching?

Increasing the face of a normal sound recording causes the curtain to rise, while reducing the face causes the curtain to fall. Time stretching algorithms analyze the sound signal to prevent this effect and regulate the reasonable segments.

What’s the curtain scroll?

This technique is a technique that raises or reduces the curtain without changing the face of the sound. This system allows us to make different sounds by changing the sound timbre.

Both procedures have disadvantages as they have advantages. Time field procedures are more successful in complex signals for music, while frequency field techniques are more successful in music.

The situation on every platform does not work exactly.

For example, platforms that offer high -quality content including Netflix and Spotify are probably used for precedent sound process, but these systems are often customized and developed in a form that will not provide open information.

In addition, some platforms or low -quality media players may not be able to protect the curtain while changing the sound face. This causes complex sounds to emerge while disrupting the naturalness of the sound. Naturally this is a low probability today.

Youtube uses Exoplayer as a media player on Android platform.

ExoPlayer uses a library called Sonic for sound manipulation. Sonic uses Picola, an algorithm running in the field of time, changes the face of the sound, helping the curtain to remain constant.

On the iOS platform, Youtube uses Avplayer’s internal playback feature. Avplayer contains internal systems for the time stretching process and thus keeps the curtain steady while changing the face of the sound.

These techniques analyze the sound signals into small sections and perform the process of adding and subtracting in reasonable segments. Or they divide the sound signal into frequency components and process each component different differently and ensure the protection of the curtain during speed change.

We are only aware of the image playback part of the event. The techniques behind the work, the sounds in the videos, natural timbre to hear the stitches for us to hear …
