OPUS Vs MP3 | Difference | Comparison

If you need to store good audio files, you will surely prefer a lossy format with high and good sound quality. Both OPUS and MP3 are lossy audio formats. OPUS is much newer, state of art technology than MP3 and has significantly better audio quality compared to MP3. Now let us have deep insight into the comparison and difference between OPUS and MP3.

What is OPUS?

The audio file in OPUS format is those that are primarily used for online streaming. It can use a range of codecs, from SILK to CLT, in addition to being a lossy format. OPUS support all of them, from low bitrates like 6KB to high values like 500KB. The format provides a wide range of frame rates and sampling rates in addition to bitrates. The audio data is stored in the container format, which is denoted by the. opus extension, which depends on the codec.

What is MP3?

The most widely used format for storing audio is moving picture layer 3 (MP3), also known as MPEG layer 3. MP3 was developed by MPEG in the 1990s. With only a small amount of storage space needed, this lossy file format algorithm can store a lot of data. Almost every device can play audio files in MP3 format, and there are no limitations on sharing or saving audio files. Online stores now sell a wide variety of MP3 players, the majority of which are free to use.

Audio format

Both OPUS and MP3 are lossy audio formats. OPUS has better audio quality than MP3.

Quality and file size

The OPUS compression algorithms reduce files while maintaining a reasonable level of file quality. When a file is compressed using MP3, the audio may suffer. Compared to MP3, OPUs produces smaller files.

Sample rate

The sample rates supported by OPUS are 8,12,16,24, and 48, Whereas MP3 supports samples rate up to 16 when using MPEG-2 and 32 when using MPEG-1, respectively.


OPUS is capable of generating audio files at a bit rate that is less than that of an MP3 file.


The majority of the music that is available online is in MP3 format. Media players and web browsers easily support this format. In the case of OOPs, it is mostly utilised for VoIP and real-time communication. Similar to MP3, it works well with media players and web browsers.
