VisualOn AAC Encoder
VisualOn provided a simple Advanced Audio Coding (AAC) encoder in early versions of Android.[5] The encoder was derived from the 3GPP reference encoder[6] and supported only the AAC-LC profile in mono or stereo. Google added a more advanced AAC codec library to Android as of the 4.1 Jelly Bean release.[7] The VisualOn encoder remains in the Android source code, but development appears to have ended. VisualOn no longer markets any commercial encoder products. VisualOn software codecs listed on its website are software based decoders and not encoders.
A cross-platform source distribution is maintained by Martin Storsjö as vo-aacenc. The latest vo-aacenc release is 0.1.3 (2013-07-27).[8] The code compiles into a shared library, libvo-aacenc. The media frameworks FFmpeg and Libav support audio encoding through libvoaac-enc.[9][10]
The VisualOn AAC encoder has been shown to be very low quality in ABX testing.[11] Of the four AAC encoders that can be used by FFmpeg, it is the least recommended option.[12]
