WAV vs. MP3 – what are these formats and which one to pick for everyday use?
MP3 is the most popular audio file format, but how does it differ from WAV?
Digital music has captured the entire world, with two main file standards – MP3 vs. WAV – but what do these words stand for, what are the pros and cons of each?
"MP3 vs. WAV" are both used in all music areas, from portable audio players to video game soundtracks and more. The apparently universal nature of both formats suggests that these formats are completely interchangeable. However, there are profound differences between them, many of which I'm going to explain. Here, I'll focus on exactly the difference between WAV and MP3 in a bit more detail.
The WAV format.
The WAV file is one of the simplest and oldest digital Hi-Res audio formats. It was originally developed by Microsoft and IBM in 1991. I'm not going to go deep into history, but, in a nutshell, Apple later derived its own version of WAV, and they called it AIFF (Audio Interchange File Format). Basically, AIFFs are Apple's equivalents to WAV files. These audio formats work by taking audio signals and converting them to binary data. In spite of being an older format, WAV has some crucial advantages when we talk about the sound quality:
- WAV is an uncompressed format – this means the recording is reproduced without any loss in audio quality.
- WAV is a simple format – files are fairly easy to process and edit.
- WAV allows us to listen to the highest recording rates with tremendous dynamic ranges (up to 192 kHz).

All this has made WAV an excellent format to work with studio records, mastering, and advanced audio applications.
WAV has some drawbacks as well:
- WAV files are large. To compare, a CD recording (44.1 kHz, 16-bit) is ~30 MB on average, while standard WAV can take up to 500 MB.
- WAVs are impractical for portable devices or streaming due to the files size. That is the main reason why streaming services always pick MP3s when they make a WAV vs. MP3 choice.
The MP3 format.
MP3 has successfully carried out a revolution in the world of music. It's the most popular and most common digital audio format. Although many think it's quite modern, its roots go back to the 70s. Unlike WAV, MP3 is a compressed and lossy format. It means that converting any audio to MP3 will reduce its original quality and also reduce the size. The reduction in size and quality results from data being thrown away.
How does it work?There are usually some frequencies that most people can't hear, so this data removed first. Secondly, some sounds are naturally loud, and they usually mask some quieter sounds. This always makes MP3 get rid of some 'hidden' sounds. Lastly, sound compression exploits that human ear hears particular frequencies better than others.
Once MP3 decided what data to keep, it's compressed again with more common compression techniques. This is then that the file's size is reduced, and most of the quality is irreversibly lost. I can't say MP3 is that bad, though.
The advantages of MP3 are:
- MP3 files are of small size. They can be effortlessly distributed over the Internet, and big music libraries stored on computers or music clouds. That is the main reason why MP3 has become a standard for purchasing music.
- The overall sound quality is usually OK for most average listeners. Using poor headphones or built-in phone speakers, you're likely to hear no difference at all.
- Converting WAV to MP3 is simple (but terrible).Taking this into account, it's clear why MP3 is a great format for distributing, streaming and promoting music. However, this comes at some cost.
Compressing a file causes quality loss. Compression can often result in strange audio artifacts that damage the audio quality, especially higher frequencies. MP3 is not suitable for mastering, mixing and recording. Lots of DJs use only the quality higher than 320 kbps to make sure all the tiniest sounds are clear to their listeners.
