Storage of Audio Files

WAV program files can be stored on CDs or DVDs. The chart below shows the approximate length of files that can be stored on each. Remember that, for archive disks, we save two copies of the program – archive and processed – so we need space for two copies of the program on the storage disk. Portable Hard Drives and USB Drives are additional storage options.
