Meridian offers a Windows-based Professional MLP Encoder for DVD-Audio applications. This encoder can create content 100% compliant with the DVD-Audio specification and can also be used for applications such as Archive. Under the GUI the user can organize workflow for encoding, downmixing, checking and decoding MLP streams. The encoder combines up to 6 channels (including mixed-rate and scalable content). Sample rates between 44.1kHz and 192kHz with word sizes up to 24-bit are accommodated. Each encoder is individually serial numbered and provides full content tracking through the use of MLP's metadata capacity.
