Audio Compression quality makes no difference at all to final size

Unity Engine

Hi all,
I imported my music in to my project (mp3 files, 128kbps but unity imported it as 156kbps) build my ipa (50.2mb) so I decided to lower the quality of the audio in unity using the slider in the inspector. I dropped the quality down to the minimum (32kbps) to test it and it made no different to the ipa size, I even ramped up the kbps to 256 and still made no difference.

Is there something I am missing here?

Thanks in advance!

Looking around, I think I managed to find an answer, because I imported the music in to unity as an mp3, Unity will not recode it. I imported it in as a wav and seem to have more control.

Be careful, though, as decompressing and recompressing audio files quickly leads to nasty quality drops. Remember that every time you compress your audio any loss and all artefacts introduced by prior compression are now a part of the source…

Within unity, wouldn’t it use the original source file when re-compressing?

What he means is, don’t convert your mp3 into Wav to put into Unity for it to re-encode… Work from original Wav then put it into unity for encoding :slight_smile:

Thanks.
