How to choose the best MP3 audio quality?
The quality of an MP3 file is measured in kilobits per second (kbps). Here’s what to remember:
- 128 kbps: standard quality, light file, sufficient for listening on a smartphone
- 192 kbps: good balance between quality and file size
- 320 kbps: CD-quality, ideal for high-fidelity audio systems
Warning: the final quality also depends on the original audio quality of the YouTube video. If the video is compressed at 128 kbps, converting to 320 kbps will not improve the output.
