Importing Audio - MP3 vs. WAV Files

Apr 09, 2012


I have several pieces of audio I need to import.  The files are currently in .WAV format.  Is there any reason I need to convert them to MP3?  (i.e. file size, quality, etc....)

What are your recommendations?

There's a trade-off. The WAVs will be much bigger in your source directory for a negligible benefit. WAVs are typically much larger but are typically not compressed. Compressing an MP3 at a high bitrate 128k will always result in a far smaller file but you risk compressing compression artifacts which will affect your final filesize and quality. It probably will be a very small consequence. I typically store as high bitrate MP3s. 

Try a little experiment. Take a long WAV and convert it to a high bitrate MP3. Import each into separate, yet identical copies of a presentation. Export and take a look at the filesize difference and quality difference. 

I predict you won't be able to tell the difference in audio quality (I can't) and the difference in filesize will be less than 1%. I may try this same experiment later today
