Which is Better: WAV VS MP3


WAV is a very common format that you may constantly come across when dealing with audio & music. It is a lossless and uncompressed audio format that is widely used and accepted by many types of devices and media software. It is often used in professional applications that are made to produce and process digital audio waveforms.


Which is Better: WAV VS MP3


WAV has some advantages over MP3, and one of them is the uncompressed quality. At the same bitrate, WAV always has better performance than MP3 when being played. Here are our suggestions on which one to use:

  • Use WAV for any media that requires top undegraded audio quality, like DVD, radio, TV, etc.
  • WAV is the best choice for audio recording and audio editing;
  • If you have plenty of disk space, WAV can bring better playback experience than MP3 (but in this case, FLAC and ALAC would be a more proper choice due to WAV’s huge size);
  • Use MP3 for almost anything online: web pages, web videos, web music, etc.;
  • Use MP3 for sharing, distribution and mass storage. Also, MP3 is good enough for human ears to enjoy music unless you have a pair of extremely sensitive and picky ears as well as a home stereo that’s worth a ton of money and capable of showing the slightest difference between an MP3 and a WAV;
  • If you want to create audio loops for your project/Flash animation, use WAV because MP3 is not good at seamless loops.
