Topic: BASSenc_AAC (AAC encoding)

[Ian @ un4seen]

Here's a little AAC encoding add-on based on the FDK AAC encoder:

   www.un4seen.com/stuff/bassenc_aac-linux-arm.zip
   www.un4seen.com/stuff/bassenc_aac-android.zip

No documentation yet, but the API is the same as the other encoding add-ons, with these "options" settings available:

  --object-type <value> ... "value" can be: 2/5/23/29/39. See here for descriptions: www.wikipedia.org/wiki/MPEG-4_Part_3#MPEG-4_Audio_Object_Types
  --vbr <value> ... "value" can be 0 (CBR) or 1-5 (VBR levels).
  --bitrate <value> ... bitrate (bps) for CBR.

The default is type 2 CBR with the bitrate based on the sample rate and channel count. No tagging or MP4 options currently, so it'll probably be mostly useful for streaming purposes (eg. with BASS_Encode_CastInit and BASS_Encode_ServerInit) rather than file writing.

AAC is patented and a licence is required to use it in commercial products. A licence can be obtained from Via:
