Advantages in Audio Formats


Does anyone know if storyline re-encodes audio when it is imported as AAC?  I have a lot of files that I compressed and they sound great.  They are also very small.  If they are re-encoded I also have these files in WAV.  So I will use these to take advantage of the new encoder.  Thank you for any help....

Thank you,

My rule of thumb when importing audio or video is this: Start with the best and then compress.

So I always try to have the uncompressed format for bringing into Storyline and then let Storyline do the compressing.

Storyline will compress audio down to MP3.  Believe Storyline is better than Presenter was at taking a compressed format and then compressing again but I'm just "superstitious" and believe it's best not tempting the "overcompression demons."

Thank you for the replies.  I am thinking that I have my mp3s just where I want them.  So I am not sure if I can set them to not try to re-compress.... Here is what I found out:

Although Storyline supports a wide range of audio file formats (AAC, AIF, AIFF, M4A, MP3, OGG, WAV, WMA), not all codecs and bitrates are supported.

We recommend using WAV files (16 bit 44 KHZ PCM WAV for best results) since this format provides the highest quality source file possible.

The audio output for published Story is in MP3 format. The bitrate depends on the setting that you choose prior to publishing. To learn how to change quality settings when you publish, please review the following article:
