Hi there,
I read the Doc about Audio notes from
http://developer.anscamobile.com/partner/audionotes
and I found that
Cross-Platform
linear 16-bit signed little-endian .WAV works everywhere. MP3 is also supported everywhere. (Though see royalty concerns.) We would like to get AAC/MP4, but this may turn out to be problematic on Android. If anybody knows of an open source AAC decoder that is non-GPL, please let us know.
Is that mean the best file format are .wav and .mp3? What royalty concerns refering to? I found some wav files are royalty free from internet, can I use them in my apps?
Thanks in advance
