I think this is a variation of the question that has been asked over and over, but I want to be sure I'm doing the right thing before buying a new field recorder.
Currently I use the Tascam HD-P2 recorder. It has 2 XLRs and records 44.1kHz to 192kHz recording resolution at 16- or 24-bit. I have only occasionally recorded at 96kHz, 24-bit but the vast majority is 48kHz, 16- or 24-bit.
I am thinking of selling the HD-P2 and springing for the Tascam DR-680. I am very happy with Tascam preamps and would like something that will give me more room if I need to record a number of inputs (like recording guns, multiple lapels, etc). It records up to 96kHz/24-bit Broadcast WAV file resolution for 8 channels (4 XLR, 2 TRS, 2 RCA) and stereo 192kHz/24-bit recording mode.
I suppose I'm not really losing anything, since it will still do 192kHz in stereo and I can do SFX recording in stereo only.
Question is - do I really need smething that high a sample rate for general film work? Usually my dialog files are 48kHz, 24-bit. Some (cough) would argue that anything recorded at 96kHz even is a waste of file space. Will I ever be asked to deliver 192kHz for dialog?
