Part 4. FAQs on How to Compress Audio Files on iTunes

Do I need to change the bitrate on iTunes to be compressed?

If we are talking about the default app, iTunes, then there is no other way to compress the audio file other than changing its bitrate. Although changing the bitrate might help you lessen the size of the audio file, you must consider that the quality might reduce once you reduce the bitrate.

What is the ideal bitrate of an audio file on iTunes should be?

Even though iTunes supports as low as 16 kbps or as high as 320 kbps, the ideal bitrate for the audio you want to compress is 80 kbps on iTunes. But remember, do not overdo it because once you lower the bitrate of audio lower than 80 kbps, you will hear a vast difference between the uncompressed and compressed audio. The 80 kbps is ideal but not the standard, so you may choose whatever bitrate you want.

Why can't I compress my audio file on iTunes?

After you change the bitrate, you must duplicate the file to make it compressed. To do it, you can follow step 4 on part 2 of this article as we indicated them for you step-by-step.


Now that you understand how to compress audio files in iTunes, it has become more accessible and precise.
