sample rate question
If I'm recording a live concert for a cd recording and also a DVD
release, do I record at 48k for the video guy and SRC to 44.1 for the cd, or do i record at 44.1 for the cd and src to 48 for the video? |

The easy answer here is track at 96 and downconvert for both (or just the CD). Absent the high sr ability, or inclination, I'd track for best match to CD, 44.1. The reasoning here is that the CD has to stand on it's own, the video has it's picture as the focal point, the audio portion is secondary and/or less critical. Top notch src should mitigate these concerns anyway. Just my $.02. rd |

Not only easier, but IME, odds improve that the result will provide the better compromise among all final formats. -- shut up and play your guitar * http://hankalrich.com/ http://armadillomusicproductions.com/who'slistening.html http://www.sonicbids.com/HankandShai...withDougHarman |

When I simultaneously record sound for video with a separate digital recorder (a Microtrack), I do one of the following: (1) Record at 24/96 when that's how the recorder was set for the last time I used it for technical measureents and I didn't notice. I then curse myself when I have to downsample to both 44 and 48 because that can be time consuming. I curse myself during the session when I start worrying about running out of space on my recorder's CF memory. (2) Record at 48 so that the sound for the video doesn't need to be resampled, and accept the time it takes to downsample to 44 since that seems to be nearly irreducable. (3) Record at 44 and get plenty of time capacity out of my flash drive and be guaranteed of audibly perfect results. I then accept the time it takes to upsample to 48 since that seems to be irreducable. If memory serves, upsampling is faster than downsampling on my DAW because one phase of low pass filtering is not required. In review, in the cold light of day, this seems to be the best option. (4) Record MP3 at 320 K, and have space to burn on my digital recorder's flash memory. But then I have to wait for it to be expanded out for the other purposes. IME the audible outcomes are all identically the same. BTW I'm probably not going to buy any more flash memory for the Microtrack because I'm gearing up to use my new Ikey RM3 for my festival backup machine, and it runs on USB and SDHC flash, not CF. The Ikey only does 44, 48 and MP3 to 320. |

My tendency would be to record at 44.1 since the CD production people probably care more about sound quality than the video production folks do. Still, these days SRC can be very, very good. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

I'm on a mac. when I record remote I like to use Pro tools because it's very stable on my laptop and will run for hours with no problem (knock wood!). but I like to mix in logic. I've been doing gorilla mastering in waveburner (part of logic) and it actually works ok. but I understand the SRC is crappy in it. waveburner is really best just for assembling a cd though. so, say I were to record at 96k, and mix it in logic at 96k. mastering (processing) should be done in logic then at 96k and then SRC down to 48 to give the video guy an aiff he can slice etc.... go back to the logic mastering session and src to 44.1 for the cd? so how do I downsample? obviously I'm a musician who's learning to engineer for my own useage mostly..... thanks for the advice!

Based on the tests posted at: http://src.infinitewave.ca/ Sox freeware, cross-platform from he http://sox.sourceforge.net/ for free looks like a good choice. |

There is an AES recommendation to the effect that the better format should not suffer the penalty of cateting for the lesser, also as I read it suggesting that 48 kHz samplerate may be the one with the brighter future. Consequently I have decided on 48 kHz as my "house standard". However after learning from the link that Arny posted how troublesome sample rate conversion can be, obviously not all tools are equally good, I certainly understand why many advocate to if possible avoid it and also that some feel that the DA-AD route is not always a bad choice.

Try it and see - if your result aren't compromised by your standards, then there isn't a problem with it !. Try a good one (SRC) though. Or choose a sample rate steered by your end product, so that SRC isn't necessary ! Round we go again ;-)..... geoff |

I'd argue that if you consider the whole chain, front to back, ending at the listener's ear, a 44.1kHz CD stands at least a better chance of being listened to on a decent system than a 48kHz DVD. It's not guaranteed, of course, but I'd lavish my attention on the audio-only format, on the premise that it's more likely to be heard properly than a video. My actual preference, however, would be to record in DSD, then make equally high-quality conversions to both 44.1kHz and 48kHz. That way neither set of listeners gets shortchanged. Peace, Paul |

I found it interesting when I sat in at a mastering session at one of the biggest NYC mastering studios for a project that involved new music (44.1) and from live videos (48), they went DA-AD without blinking an eye. Although it was almost a decade ago and conversion tools have only improved, it drove that point home to me at the time. |

Odds are they had really top grade converters.... unfortunately not everybody does. But these days even the cheap converters tend to be a lot better than they used to be. --scott -- "C'est un Nagra.

Things may have changed a bit since I read the mastering book (and I can't remember if it was in Bob Katz' or Bobby Owsinski's) but at the time it was quite common for the first thing in the chain that a digital master hit was a D/A converter so the engineer could use his analog processing tools. Of course they have good converters, though, since the mastering engineers are the only ones making any money nowadays. -- "Today's production equipment is IT based and cannot be operated without a passing knowledge of computing, although it seems that it can be operated without a passing knowledge of audio." - John Watkinson http://mikeriversaudio.wordpress.com - useful and interesting audio stuff |
