MP3 Vs. WMA Quality

MP3 and WMA are file formats for music. Both are compressed versions of the original music or sound recording. Each format has benefits and disadvantages. The quality of MP3s and WMAs can differ greatly. How you plan to use the music file can determine the appropriate file format.

MP3

MP3 stands for Moving Pictures Expert Group, Audio Layer 3. Approved as a standard music format in 1991, MP3 format is the most commonly used by consumers for digital music playback. MP3 format involves the compressing of the original music recording, making it easier to transfer and store without sacrificing a lot of quality. An MP3 file created at the 128 kilobits per second speed can be up to 11 times smaller than the original recording.

WMA

The WMA format stands for Windows Media Audio. It was developed by Microsoft as the format to be used with the Windows Media Player that is standard issue with all versions of the Windows operating system. WMA files also use a compression algorithm to create smaller versions of audio recordings with quality sacrificed as little as possible. Microsoft claims that at 128 kilobits per second, WMA files are near CD quality. This claim is sometimes contested by audio experts.

Quality Differences

Both MP3 and WMA files are capable of producing audio at near CD-level quality. However, MP3 files are able to produce a better fidelity even when streamed at lower Internet speeds. This is how MP3 became the standard format for streaming Internet audio. WMA files require more bandwidth to create the same fidelity, but WMA also takes less processing power to decode into music.

Ease of Use

MP3 files are very easy to transfer to mobile devices and burn to CD's for listening on the move. Stereo CD players can have the feature to read MP3 files, allowing users to burn data discs of MP3 files. This type of disc can hold hundreds of songs instead of being limited to an audio recording time. WMA files cannot be easily converted to other formats due to its encryption process. For this reason, WMA files are not useful for much more than playing on a home computer or laptop.

Ever Changing Industry

Both MP3 and WMA formats are constantly improved by computer companies. The quality levels can vary with the updates. WMA may be superior to MP3 after an update, but then MP3 will be updated as well and jump back to the top. Competition drives these formats to constantly improve.
