WAV and MP3 are the most used audio formats today, so why must we convert.WAV to.MP3? As we all know, the WAV format is an uncompressed lossless audio format commonly used in CD recording, mastering, and advanced audio applications. WAV files are typically huge since they are uncompressed. To clarify, a CD recorded at 44.1 kHz and 16-bit takes roughly 30MB on average, and a typical WAV can take up to 500MB.

As a result, WAV music files are impractical for portable devices and online distribution, particularly in the current streaming era. Consider iTunes, Spotify, and others; why do those streaming services offer MP3 audio instead of WAV? The argument could not be clearer! The issue is file size. MP3 is a lossy audio file that takes up much less free space but still provides fairly beautiful sound effects, particularly at a higher 320 512 kbps. Furthermore, because the difference between a WAV file and an MP3 file on a portable device is not that significant to normal listeners with inadequate headphones or earbuds, it is quite fair to convert WAV to MP3 so that even hundreds of songs do not consume too much storage space on your smartphone. After you understand why you need to convert WAV to MP3, let's move on to how to convert WAV to MP3, with desktop converter software and online service.

Part 1. The Difference Between WAV and MP3

WAV files are raw audio files developed by Microsoft and IBM. They are container files storing the sample, tracking numbers, and other sample and bit rate information. They are usually uncompressed audio files. However, they can support some forms of compression if necessary. In general, they contain lossless audio, which implies a lot more detail is recorded in the file. The disadvantage is that the files can be substantially larger, with some exceeding 4 GB.

On the other hand, MP3 files are lossy audio files using a compression method that results in a substantially reduced total file size. Because the compression that occurs cannot be reversed, data is lost. This is why it is referred to as lossy. This data loss does not have to imply a loss in audio quality, but it can reduce file types by up to 80 or 90% in an MP3 vs. WAV test. For example, a 25 MB WAV file could be compressed to a 3-4 MB MP3 file. In addition, MP3 files are quite popular because compression usually does a decent job of maintaining audio while drastically reducing file size. This was especially beneficial in the days of smaller hard drives in MP3 players and computers.
