Hi Hilary, 

Although Articulate Storyline and Articulate Studio '13 support a wide range of audio file formats (AAC, AIF, AIFF, M4A, MP3, OGG, WAV, WMA), not all codecs and bitrates are supported. If you encounter either of the issues described above, we recommend converting your audio files to 16 bit 44 KHZ PCM WAV for best results.

But as you mentioned, they will be encoded as MP3.
