Double Wide

One format of AES/EBU data transfer that accommodates higher sample rates such as 96 kHz. Since the AES/EBU standards didn’t originally include specific guidelines for transmitting audio data beyond 48 kHz, a couple of standards have more or less “emerged” on their own. The Double Wide standard breaks high sample rate audio, such as 96 kHz, up into two different 48 kHz AES data streams and transmits them separately. The double wide standard requires two AES “channels” (meaning two jacks, and two cables) to transmit a stereo pair of audio channels. The other common high bandwidth AES format is Double Fast, which essentially doubles the data rate of an existing single channel AES data stream and sends it over one cable.
