Part 2. Settings That May Influence MP3 File Size Other Than Bitrate

Aside from the bitrate, there are many factors why the MP3 file size is enormous. If you want to know what these are, you must keep reading it to know more about the other setting that MP3 files have and the huge file size.

First of all, the duration and the length of the audio or video significantly impact the file size; the longer the time of the video, the higher the file size will be. Next is the sample rate; if the bitrate is on the quality, the sample rate focuses on the audio's detail. The higher the sample rate is, the better the audio detail will be, but the file size will be enormous. If your audio uses lossless compression, that is why the huge file size. But the MP3 files are lossy, which means that the file is 90% smaller in size than the other uncompressed audio files like WAV. The metadata is the data that is within the data. Most audio files have metadata because it has the essential data that the audio file has that sometimes we can't see on the audio we are listening to. It includes the author's name, song's title, date and time, location, album art, etc. This simple data can also extend the file size of the MP3 file you have. Now that we know, you can reduce the file size by cutting the video to reduce the duration, downgrade the sample rate, and remove the metadata to save some space.
