Application Notes:
Encoded Stream Generation
dScope Series III is capable of playing back arbitrary waveforms from its generator sample buffer. This can include playing back encoded digital streams such as Dolby Digital or DTS encoded streams from the S/PDIF or AES3 outputs. Since this is a buffer of finite size, the files that are to be played back have to be looped in order to create continuous steady state playback. Encoding streams that loop correctly at block boundaries and without glitches in the audio is a complex and time consuming undertaking which is compounded by the need to encode them repeatedly with different encoding settings such as number of channels, bit rates etc, not to mention the licensing required for the encoder software. All this complexity and cost is removed with the dScope Encoded Stream Generation as all the encoding has already been done using an automated system and the resulting encoded files are supplied for free without license restrictions along with user interfaces for selecting the files and loading them into the dScope generator. This application note covers the installation and usage of the dScope Series III implementation of Encoded Stream Generation.
