Wav and mp3, what are the differences.

MP3 versus WAV

Digital sound sources have become part of everyday life.

 

Nowadays, many people listen to music between school and work, and play music from their PCs and smartphones. Now that YouTuber is on the rise, it is difficult to break ties because it is next to MP3 and WAV. You will always be indebted to the scenes, such as applying the sound source to the image and adding sound effects. Here, we will mainly introduce the differences between WAV and MP3.

What is WAV
WAV is also known as PCM or WAVE sound source, and refers to the format of uncompressed digital sound sources. Since the sound source is not compressed, it is characterized by the same high sound quality as the recorded sound source. on the CD.

The only downside to WAV is that the higher the sound quality, the greater the amount of information that will be captured and the larger the file size. If you compare it to a 5 minute sound source file, it will be 50MB.

What is MP3?
MP3 is a lossy compressed WAV file. Lossy compression can significantly reduce the amount of data, but compressed data cannot be restored to original data even if it is decompressed. You need to be careful about the conversion as it is a way of degrading the data.

At the same time that the sounds that humans cannot hear are eliminated, the amount of data can be compressed to about 1/11 while maintaining the same sound quality as music CDs.The difference between WAV and MP3 is whether it is compressed or not.

5 differences between WAV and MP3

To briefly explain the difference between WAV and MP3, WAV is an uncompressed raw sound source, so the sound quality is very good, but the capacity is very large. On the other hand, MP3 reduces the capacity of WAV to the remove only the data that the human ear cannot hear to reduce the WAV capability. When used for video editing, MP3 can be used for short videos for SNS. WAV is used to write images to discs like Blu-ray.

Difference between WAV and MP3 1: frequency difference

First of all, WAV and MP3 have different frequencies. It is easy to understand by frequency analysis, but WAV can express all sound sources in frequency, while MP3 only has the last part cut off. Even if you convert MP3 once converted to WAV again, the sound quality will not improve.

Sound is a vibration that is transmitted through substances such as air and objects, so it is transmitted in the form of waves to the human ear.Human beings can perceive sound because it travels through the air to the human eardrum in wave form.

Difference between WAV and MP3 2: difference in data capacity

WAV and MP3 have different data capacities. MP3s are created by compressing WAV, so they have a smaller capacity than WAV. WAV is about 50MB in 5 minutes, but it typically becomes about 5MB when compressed to MP3.

To convert WAV to MP3, there is a service called OnlineVideoConverter. It can convert WAV to OGG, AAC, WMA, and MP3.

Difference between WAV and MP3 3: difference in sound quality

WAV and MP3 also have different sound quality. Since WAV is not compressed, it has not deteriorated and it is characteristic that you can enjoy music with beautiful sound quality. Smartphones and tablets are large in size, so it will be difficult to run them smoothly.

Since MP3 is WAV compressed data, its capacity is small. Since the capacity is light, it is ideal for attaching as data. Sound quality has deteriorated, but only sounds that are inaudible to humans have been removed.

WAV vs. MP3

Lossy sound?

In the case of a WAV file, if you play the exact same WAV sound source file with the sound waveform reversed and the original waveform file together, you won’t hear anything.

So by applying Audition phase inversion to a WAV file and playing it at the same time as the MP3 version file, I tried to extract the sound that is irreversibly compressed and can be heard in WAV but not MP3, commonly known as ” Lossy Sound “. !!

0.03 Original WAV sound source (①)
0.08 Inverted WAV sound source (②)
0.15 ① and ② (silence)
0.22 MP3 sound source (③)
0.28 ② and ③ (Lossy sound)

It flows in the order of.

abstract
I’m sure there are people who think this lost sound is not a big deal, and people who think it makes a big difference.

Personally, when I listened to Lossy Sound, I thought that the thickness and sound of the sound was considerably lost in MP3.

The music used in this check was a song with a high range overall, so if you want to compare it to music with a strong mid-low range, check out the video below!

In this video, you can compare WAV and MP3 with a famous song called Take Me To Church by Hozier.

Lossy Sound will play starting at 2:47.

By the way, the response from the listening comparison test was
①WAV → ②MP3 → ③MP3!

To be honest I heard it many times
and I finally thought it was different, but when I heard Lossy Sound

WAV vs MP3

I heard that there is a difference in sound quality between WAV and MP3, but how much is it really different?
Does anyone think so?

WAV vs. MP3

Even if you theoretically know that a WAV file is a lossy compressed file, it is an MP3 file, but it seems that few people really compare the WAV file and the MP3 file of the same song.

Lossy compression is a compression method that can significantly reduce the amount of data, but when compressed data is decompressed, it is not fully restored and data loss (corruption) occurs.

This time, we will do a simple check so that you can understand the difference between WAV and MP3 more deeply by learning not only the form and theory, but also the sense of hearing!
Even if it says verification, just listen and compare!
I hope you have read this article and used it as a basis for deciding whether to use WAV or MP3 in the future.

From the meaning of the terms to the operation procedure, we will explain it smoothly with pictures.

Difference between WAV and MP3
For those who don’t know what the different format of WAV and MP3 is, I will explain it in words first.
If you already know, go to the “Listening Comparison Test” below.

In short, a
WAV sound source is a format that preserves the same sound quality as an uncompressed recorded state.
The sound quality is good because it is not compressed, but it also has the disadvantage that the file is very heavy.

Secondly,
MP3 is a file that is significantly lighter by removing only the sounds that are inaudible to humans in the WAV file to lighten the sound source file that is too heavy for WAV.

By the way, for reference, the size of the same WAV and MP3 file
it’s 9.2MB, which is less than 1/4 of that, while WAV is 41MB.

The file is very light, but let’s check how much sound is gone.

Comparative hearing test
In fact, I prepared the MP3 version and the WAV version of the same song.
If you say this is MP3 and WAV first, you may hear WAV better due to biases, so first try listening to the sounds without saying which one …

Play the same phrase from the same song three times.
Of those three times, we will answer after the final summary if each was MP3 or WAV.

People with very good hearing can hear it because it only cuts out sounds that humans shouldn’t be able to hear, but it doesn’t matter if they can’t be heard.
