Expert Audio™

Expert Audio includes flexibility in the encoding parameters to provide the highest quality audio encoding on every audio bit-stream. Also Expert Audio provides the user with detailed statistics during the audio compression process. Additional functionality available upon request. Expert Audio is capable of decoding your MPEG audio bitstream into WAV or PCM.

The Expert Audio produces a compliant MPEG-1 or MPEG-2 bit-stream. The Expert Audio not only provides a complete set of multiplexing parameters, but also provides visibility into the encoding operation. The Expert Audio can also be run in a batch mode. This allows you to automatically encode a large group of files. The Expert Audio reads a parameter file upon start up so that parameters can be customized for each file to be encoded. The batch mode provides a convenient way to work with the other PixelTools products (like the Expert-DVD Video Encoder and Expert-Multiplex,MPEG Multiplexer) to encode video and audio clips and multiplex them into system streams with specific audio, video, and multiplexing parameters automatically without human intervention.
