|Here's the excerpt from our 2011.2.0 Release Notes:
The DLL now supports MP4-AAC formats for reading and writing.
Creation of AAC (Advanced Audio Coding) files, either “raw” or embedded in an MPEG-4 container is supported.
Audio32.dll uses MainConcept DLLs for AAC-encoding and MPEG4-muxing. These have to be installed to activate this feature and are part of the Audio32.dll package.
Copy audio32.dll into your DigaSystem directory
Copy required MainConcept MP4 filters mc_dec_aac_ds.ax and mc_demux_mp4_ds.ax into the DigaSystem folder (all files in folder “MPEG4-AAC-Codecs”)
Register the two files mc_dec_aac_ds.ax and mc_demux_mp4_ds.ax using regsvr32.exe
Conversion from and to MP4-AAC is supported using DigaPorter, DigAlign, DigaTransferSystem
(please refer to Audio32-documentation for format string)
For the use of DigaPorter the new option "Advanced Audio formats" setting must be set in “Converter Audio” section to configure format strings
Also successfully tested was an audio extraction from MP4-H264 video to broadcast audio (linear, mp2) using the audio32
Automated transcoding with Database Manager (DBM) – if auto-conversion is configured for a table an MP4-AAC file could be dropped into DBM and auto-conversion converts in the pre-defined format
This works only for MP4-AAC as source format! Creation of MP4 files using D&D operations is currently not supported (requires changes within DBM code)
Currently conversion is supported with this release.
Pre-listening of MP4 files within DBM is not yet fully supported and will be available in a separate patch at a future date
Also support for MP4 within the DigaSystem editors is not fully supported and will be implemented within a separate editor patch at a future date.
