To give it a start, let’s try to understand the fundamentals of these file formats. The three are among the most famous file formats. Millions of people widely adopt them to record and listen to music, upload music online, and download their favorite music. A normal human might not even notice the difference in music while playing the files. But as a matter of fact, there is a huge difference.
Before we discuss why WAV file formats are better than the other two audio file formats, let’s understand audio formats. Audio File Formats are mainly classified into two categories: lossy and Lossless.
What are Lossy and Lossless Audio File Formats?
Lossy File Formats are the audio formats that lose some of the data during the file transmission as they will be in compressed form. However, they do not compress back to their original file size, and the process loses some audio waves.
Lossless audio file formats remain uncompressed even after transmission and do not lose data. Therefore, people globally prefer them as the best file formats.
WAV file is one such audio file where the data quality remains intact, which is one of the major reasons to choose it over MP3 or WMA.
Now, let us walk through to know what WAV files are and understand their advantages over other formats.
What is a WAV file and When to use WAV files?
WAV stands for Waveform Audio File Format. These files are uncompressed and provide lossless audio. WAV audio format is the most appropriate for TV, DVD, Radio, or any music player to get that uncompromised audio quality.
Amidst the transforming technology, there are several recording techniques adopted by musicians. Most people record with the help of mixers and a small acoustic room termed a studio. So, if you are recording in your studio or listening to music for a gig, go for the WAV format music file instead of lossy MP3 or WMA. Most technicians and DJs prefer this file format during studio recording. If you have lost some important recordings and want to retrieve them, you can recover them easily.
Why is WAV the best format for music?
As explained earlier, WAV uses lossless sound quality, so WAV files have a very high sample rate and bit depth. This allows them to include all the frequencies the human ear can hear. The upper limit of the WAV file is up to 22KHz, which a few people with trained ears can detect. This can be natural, with many people listening to frequencies around 22KHz.
This file format is standard for audio on PCs. It stores the data in chunks, like RIFFs, and codes it with PCM (Pulse Code Modulation). The PCM technique samples analog sound waves at regular intervals. These WAVE files are bulky, and any minute mistakes while saving, copying, or using a bad WAV player can cause deletion or loss of the file. If it happens, recovering deleted WAV files can be a task. Always be cautious while dealing with WAV files to avoid damage.
The advantage of using WAV files is that they contain more details, and you can obtain more precise sound with them.
What is MP3, and how does it work?
MP3 stands for MPEG Audio Layer 3.
This file format is famous and known as the MP3 file format with an extension of .mp3. MP3 is one of the most used music file formats on the Internet. Because of their small file sizes, MP3 files can be loaded rapidly. It is one of those file formats that is widely used because it is compatible with various devices and platforms.
Advantages of MP3 File Formats:
- MP3 files are small. They can be easily shared over the Internet, and big music libraries are stored on computers or music clouds.
- The overall sound quality is average and is satisfactory for most average listeners. You’re likely to hear no difference using poor headphones or built-in phone speakers.
Why are WAV files better than MP3?
There are some aspects of a .mp3 file that make it lag behind WAV or WMA.
MP3 is a compressed music file format that uses the lossy algorithm to delete the less audible music content to reduce the size of the file. This type of file contains compressed sound data, which is one of the basic reasons for its not being the best. It gives an average-quality sound with a loss of frequency, thus compromising the music quality.
The basic reason behind the MP3 file format is to cut off the access data in frequency. The access data would be a frequency that is a little beyond the hearing range of human ears. To do this, the files are compressed, and the quality of sound declines. A normal human can perceive up to 20KHz, but the general limit is believed to be 18KHz, and so is the MP3 file format.
What is WMA used for?
WMA stands for Windows Media Audio.
Developers created this file format in the late 1990s to overcome some of MP3’s flaws. With its new technique to compress audio data, it gained popularity among some circles. WMA file compression uses several standard compression methods. Which slightly improve the audio quality compared to the compressed file format of MP3.
However, this file format did not gain the support of many users. This was partly due to the restriction of devices, as many devices could not play WMA files. It was also partly due to the fact that its compression method basically concerns saving a little bit more than MP3. Thus, it uses less storage space than MP3 as it uses a different encoder.
Five Major Reasons to Choose WAV over MP3 and WMA
Now we come to the point where I will tell u why exactly you should go for WAV instead of MP3 or WMA file formats. If you have anything to do with studio or recording, it is a priority for you to use WAV format. To get uncompressed lossless sound quality. Here are some reasons why I choose WAV over MP3 and WMA:
Frequency Response
The uncompressed WAV file has a full frequency response of around 22 kHz, which provides a better range for human hearing. As for the MP3 files, the maximum frequency response would be around 18KHz, much lower than the upper limit for WAV files. As for the WMA files, there is a very small difference in the frequency response of WMA and MP3 files. This frequency difference can suppress many sounds and hence reduce the sound quality.
Seamless Loop
Using the MP3 to create a seamless loop is impossible, whereas, with WAV, you can create a seamless loop and play sound without any pause or sound gap. Also, using a WMA file in such cases is not a good idea. So, if you are working on a new music project and want to create a sound file with minimal sound loss, WAV is your best option.
Sound Mastering
While mastering the sound, using the MP3 with mid-side processing is useless if you are enhancing the side sounds. MP3 and WMA formats chop off or compress those sounds, replacing them with digital bits to fill the gaps. This would never give you a good sound.
But if you look at the same procedure with the WAV file, it will give you amazing results as it is lossless. It gives an excellent result while mastering or using a midi processor.
Encoding
If we compare the WAV file’s application to the WMA and MP3 files, it has a number of advantages. However, there is a peculiar difference in encoding between them. This is the basis of all the differences among the three formats.
MP3 contains bits of digital noise and compressed sound files. The WMA file contains compressed sound files like MP3. The WAV file contains data encoded with LPCM and ADPCM. It can even contain MP3-encoded data.
This is evidence of the high-quality sound delivered by the WAV file format.
Last but not least, you should choose WAV over MP3 and WMA because of storage.
Storage
The issue of storage is not a big deal these days. You should still consider it one of the most important factors. Space or memory is one of the first reasons MP3 exists. They created it to save space that was previously occupied by WAV files. These large and bulky files can eat up a huge space in your system.
The evolution of the WMA file format was to counter MP3’s drawback and maintain the advantage of acquiring less space.
WAV files are lengthy and heavy sound files that contain almost all the information in the form of sound. Thus, it is always recommended that professionals use the WAV file format. Over the years, the issue with space has declined gradually. Now, we have plenty of space on our devices, so keeping a number of good-quality audio files as WAV is not an issue these days.
Conclusion:
Finally, we can conclude that the WAV file format is the best choice if you want professional music. Even the CDs we listen to have the music in WAV format. MP3 and WMA are popular and widely used because they are small. But for those who like to listen to high-quality music, we have WAV. Now, you know why you should choose WAV over MP3 and WMA. Let us know if this article has helped you make a better choice.
