fhgaacenc (fhgaacenc.exe) must be downloaded separately (e.g. from https://github.com/tmkk/fhgaacenc).
Since "fhgaacenc.exe" also needs the mentioned Winamp DLLs ("enc_fhgaac.dll", "nsutil.dll" and "libmp4v2.dll" as of version 5.62 or above) you also need to install Winamp and copy the Winamp DLLs from the Winamp resp. Winamp/PlugIns folder into the same folder which contains fhgaacenc.exe (or you might also copy "fhgaacenc.exe" and "libsndfile-1.dll" into the Winamp/PlugIns folder).
The FHG Winamp AACPlus library does not support 32-bit floating point sample data as input, so the BASS_ENCODE_FP_32BIT flag will automatically be used.
This implementation uses the automatic DSP system for encoding. Meaning the sending of sample data to the encoder is done automatically when you play the channel (BASS_ChannelPlay(Int32, Boolean)) or call BASS_ChannelGetData(Int32, IntPtr, Int32) (if it's a decoding channel). So there is no need to call BASS_Encode_Write(Int32, IntPtr, Int32) manually!
The extension of the OutputFile can be either .acc to write an aac bitstream output file or .m4a/.mp4 to box the output to a MP4 container (note, that using m4a/mp4 requires "libmp4v2.dll" to be present).
If you simply want to encode a physical file please also take a look to the EncodeFile(String, String, BaseEncoder, BaseEncoder ENCODEFILEPROC, Boolean, Boolean).
