Tried to ingest two wav 48khz files today (recorded on a Tascam DR100 MKII). Opened ingest window selected both files and ingested. Bottom left scale showed they were ingesting, but Prelude gave an error saying it could not process the files. Though they were not in the Prelude bin, looking at the hard drive showed they had transfered from the 16gb SDHC fine and they played fine in finder window and also after bringing into Premiere.
My CS6 Prod Prem updates are the latest, MBP 17", Lion, 16 gig ram
Sorry, Glitchdog, Prelude does not support ingest of audio-only clips, it needs video clips or clips with video and audio.
