Both MP3 and WAV files are digital audio file formats commonly used for storing and playing audio. However, they differ in terms of compression and audio quality, with MP3 files being compressed and WAV files maintaining uncompressed audio data.
So let us examine the query more closely
Both MP3 and WAV files are commonly used digital audio file formats, but they differ in terms of compression and audio quality. While MP3 files are compressed to reduce file size, WAV files maintain uncompressed audio data, resulting in higher audio fidelity.
Interesting facts about MP3 and WAV files:
Developed by the Moving Picture Experts Group (MPEG), MP3 stands for MPEG-1 Audio Layer 3 and is a widely used audio format.
- MP3 files use lossy compression to reduce file size, discarding certain audio information that is less perceptible to the human ear. This results in smaller file sizes, making it more suitable for online distribution and portable devices.
- The use of psychoacoustic models in MP3 compression ensures that the removal of audio data is done in a way that is generally imperceptible to the listener.
Due to compression, MP3 files typically have smaller file sizes compared to WAV files, making them more convenient for storage and transmission.
WAV (Waveform Audio File Format) is a widely supported audio file format developed by Microsoft and IBM.
- Unlike MP3, WAV files are uncompressed and store audio data in a raw, lossless format, preserving the original quality of the recording.
- Due to their uncompressed nature, WAV files contain more audio data and thus have larger file sizes compared to MP3.
- WAV files are commonly used in professional audio applications, such as audio editing and mastering, where retaining the highest quality is critical.

Comparison of MP3 and WAV files:
Below is a table highlighting the key differences between MP3 and WAV files:
|File Size||Smaller file size||Larger file size|
|Audio Quality||Lossy compression, reduced audio fidelity||Lossless, retains original audio quality|
|Usage||Portable devices, online distribution||Professional applications, high-quality audio|
Keep in mind that while MP3 files are more widely used due to their smaller file sizes and convenience, WAV files are preferred when absolute audio quality is paramount, such as in professional audio production or when archiving original recordings.
Answer in video
The video compares WAV and MP3 audio files, highlighting their differences in storage, quality, and compatibility. MP3 files are compressed and smaller, making them more convenient for various devices, but they sacrifice some audio quality. In contrast, WAV files offer higher quality audio but are larger and less compatible. It is recommended to record in WAV for editing control and then choose whether to export as MP3 or WAV based on factors such as content type, budget, and audience preferences. The video emphasizes the significance of understanding audio formats and their impact on quality.
Some more answers to your question
MP3 files are much smaller and have been compressed so they lose some data. WAV files are usually lossless and have not been compressed, so they have more data. This means more in terms of file size, but also usually means better quality of audio and more options for editing.
In short, WAV files are the larger counterpart of MP3 files. These two often go hand in hand—most times, when you’re converting a preexisting audio file to MP3 in order to save space or make it more portable, the original file that you’re converting from is, in fact, a WAV file.
Back in my days as a Music Engineering graduate student I participated in a double-blind study to determine exactly this. We were uniquely suited to the task, being trained as a bunch of future perceptual-coders who knew what to listen for surrounded by jazz and classical performance majors who definitely did. The chair of the department, Ken Pohlmann, was an AES legend in his own right and had plenty of student guinea pigs (as well as golden-ears inside the codec community) to evaluate each new generation of codec, and this was fairly early on (late 90’s); MP3Pro wasn’t out yet, and AAC was still years away.
The only thing I got out of the testing was a listening headache along with the fact that our guesses were little better than chance in determining which recordings were CD and which were high bit-rate lossy MP3.
So, double-blind testing made believers of us all. The exception? Ken told us about one legendary student who was casually effortless at telling them apart and when ask…
• MP3 uses lossy compression during the encoding. WAV is a lossless file format and uses linear pulse code modulation. Compressed audio can be encoded into a WAV file too, but it is not in the common usage. • MP3 files have a smaller file size compared to WAV because of the lossy compression in the encoding.
