Understanding dLive USB Recording and Playback

dLive offers the ability to record and playback stereo (2-track) audio directly on to a USB device.
The recording format is .WAV 96kHz 24-bit.
dLive audio recording requires the USB storage device to support high sustained transfer rates. Not all USB devices will guarantee flawless performance - when a USB device causes a pause that is longer than the buffer time in the mixer, a dropout occurs and data is lost.
Please refer to the following guidelines for sourcing a suitable USB device:
Maximum USB drive size (FAT32 file system limit) is 2TB.
We recommend you use the USB hard drive for dLive USB Recording and Playback only. Do not use it for other applications including storing shows or installing firmware.
Format the hard drive on the dLive mixer before use. This clears the drive, sets up the dLive recording and playback directory structure, and formats into FAT32 with a constant cluster size of 32kB.
Please refer to the dLive Firmware Reference Guide for an overview of dLive supported file formats, data rate, folder structure and file naming, patching and instructions on playback and recording.
The maximum file size on FAT32 is 4 GB. dLive audio data rate per track is 33.8MB per minute / 2025MB per hour. This allows a maximum recording time of 118 minutes.
Note - .wav files imported to the USB drive for Stereo playback via dLive must be INTERLEAVED stereo tracks, and placed into the AHDLIVE/USBPLAY folder.
Note - a USB drive that works well in the DATA socket (i.e. for storing shows and installing firmware) will not necessarily have the performance requirements for USB Playback and Recording
