SUPPORTED ENCODINGS/FORMATS: - 8-bit u-law/A-law - 8, 16, 24 & 32-bit linear (PCM) - IEEE Float (32 & 64-bit) - G.721 (4-bit, untested) - G.723 (3 & 5-bit, untested) Fragmented files are not supported at the moment. INSTALLATION: 1. copy the file SUN_AU to DEVS:DataTypes/. 2. copy sun_au.datatype to SYS:Classes/DataTypes/. Alternatively, if you have the OS4 SDK installed, you can just type "make install" and both files will be installed to their correct places. BUGS: None known. If you find any, contact me by e-mail (fredrik at a500 dot org). The same goes for (if you have any) .au/.snd encodings/formats that are not yet supported in this datatype. COMPILING: To compile just type "make". To compile without G.72X support use "make G72X=0". In order to be able to recreate the descriptor (from AU.dt) file you will need to have the MakeDT.rexx arexx script installed in REXX: (can be downloaded from http://aminet.net). The rest will be handled by the Makefile. CHANGES: 50.2 - improved low memory handling. now tries to allocate a smaller decode/encode buffer if there isn't enough free memory for the default size (~16kB). previous versions just returned an error if this was the case - added back DTM_WRITE support which seems to have gone missing from the previous version :-(. fortunately I had a backup of the v0.3 sources so I didn't need to rewrite the code for this 50.1 (27-Feb-2006) - enabled G.72X support (untested) 0.3 - GetAU() now obtains it's file handle properly with DTA_Handle tag instead of IDOS->Open() - added support for writing in native format, like in wave.datatype - changed name (sun_au.datatype -> au.datatype) 0.2 (5-May-2005) - fixed memory trashing in au_class.c (was the cause of some instability) 0.1 (26-Apr-2005) - first released version of the datatype
