Fostex MR-8HD
Has anyone used the Fostex MR-8HD 4-track recorder? I am considering it for simultaneous 4 channel recording auxillary to my video camcorder, than mixing the audio in post-production. Anyone have experience with this unit?

FWIW, don't have any direct experience but something I noticed you might keep in mind is that it only records in the CD sampling frequency of 44.1 kHz. This will require resampling in post in order to more easily maintain synch with the in-camera audio which is recorded at 48kHz. Not a major glitch but it could be an issue. You might want to find a recorder that will record at a 48kHz sampling rate.

Thanks Steve for the feedback. The 44.1k to 48k conversion is not really such a problem and at least it is a known quantity.
What attracted me to the Fostex is the 4 channel simultaneous recording, the convenient inputs (XLR, 1/4"), the high capacity hard drive which allows lossless recording (not compressed) for a two hour performance and the digital output to my computer through a USB port. And, most importantly, it is $400. If I could get all these features for a comparable price but with 48k sampling I would. I do not need long battery life since I will be in a theatre recording stage performances with power available and a sound booth providing the music (from CD) channels and ambient (from two microphones) tracks. |

When I said that the sample rate conversion was not such a problem, I didn't mean to simply ignore it. You are correct that that would be a big mistake. Since I am recording a ballet that goes on for about 45 minutes per act, synchronization of audio and video could be off by minutes - even without the high visibility of spoken dialogue, this large of a synchronization problem would be readily and painfully noticeable.
I meant the conversion can be done with any number of software programs, Cooledit (now Adobe Audition) is probably one of the best for high quality conversion. I am sure the analog to digital conversion when the sound is originally captured will introduce a lot more noise than the subsequent resampling. The final product is a DVD with the audio dolby compressed so audio is further degraded in quality. However, I agree with you that it would be much nicer if the Fostex unit sampled at 48kHz. |
