Factors related to audio file size

 

The audio file size can be influenced by several factors which include codec, audio settings like bitrate, channel as well as sample rate.

 

Factors related to audio file size

 

Codec explains the way how is an audio file compressed, which means how small audio file size you will get. Bitrate determines the quality of an MP3 file and higher bitrate leads to better audio quality and larger size. Channel shows the way audio travels from the source to the destination. A stereo source has two channels and a mono source just has one. Sample rate is related to the number of samples of audios carried per second. Lower sample rate means smaller size and MP3 files usually use the sample rate of 22.05 kHz.

Any audio of 128 kbps can offer CD-quality sound in the condition of high-quality audio source and good type of speaker or headphone you use. Generally speaking, if the sound is below 128 kbps, it will be easily distorted and if it’s at 8 kbps, it will be hardly recognized.

 


Quality VS Size

 

Quality VS Size

 

As we know, there is a relationship between audio size and quality. To get the sound in top quality, you must accept the largest file size. On the contrary, smaller audio file size results in lower quality. After you are clear of this fact, you have to decide which one to choose: quality or size. That depends. If your audience have enough time and patience for downloading a high-quality audio file, you can choose quality. If they prefer faster download speed and think the low-quality audio is acceptable, you can choose smaller size. You need to be deliberate in the process of making a decision to get the best compromise between them.
