I'm looking for some "best practice" advice for the audio side of my railway video productions. I described my set-up (http://www.dvinfo.net/conf/showthread.php?s=&threadid=26338) at some length when I joined dv-info last year, so I won't repeat myself here.
For monitoring, I have a TV monitor (old Philips 8853 with two speakers built-in), 4 little speakers and 1 small bass-speaker that came with my Audigy Live sound card, or a pair of Beyer Dynamic headphones, which I guess are my best bet. With very little effort, I could move a hifi amp and a pair of small KEF speakers into my den. The room is pretty dead, acoustically - lots of shelves, lots of clutter, few hard, flat surfaces. What I don't have are proper near-field monitor speakers.
On my last production, I spent a long time manually adjusting the volume level of each clip to keep it below -6db, following some advice I'd read about DVD audio. It took longer than the rest of the editing and DVD-authoring put together. Was this worth doing, do you think? Surely there's a better way?
The main weakness of my NLE (Liquid Edition 5.62) is a lack of audio tools: no compressor (I've been warned off the "maximiser" tool), only rudimentary echo and EQ, and no support for plug-ins. I know this has been addressed in the new version (LE6), but there are too many bugs in that at the moment, and besides, I need some hardware upgrades before it will run well on my PC. If I'm going to do anything other than volume adjustments, I need to export to another program. I have recently down-loaded the demo version of GoldWave for this purpose
The live sound track is basically the sound of the trains approaching, passing and going away. Sometimes the camera is right beside the railway line, so the camera's ALC (the XM1 does not have manual over-ride) is reducing the volume a lot; sometimes the trains are quarter of a mile away, e.g. across a valley, and their sound hardly registers. Normally, they pass about 20-100 yards from the camera. The important thing is that it should sound completely natural.
Here's what I think I probably ought to do:
1) In LE, finish all the editing, boost or cut the volume at specific places where needed (e.g. when a car passes out of shot), and add sound effects (not usually necessary for my stuff).
2) Export the sound to GoldWave as a 16-bit, 48kHz .wav file. I'd probably do this as a few 15- to 20-minute chunks rather than one complete 75-minute file (that's how I usually structure my productions).
3) Add EQ and/or compression to compensate for microphone characteristics and camera ALC. I presume that this is the bit that needs most skill, and where good advice will be very much appreciated. One thread I saw around here recommended some settings for "gentle" compression - threshold = -19db, ratio = 2:1, 0.1 msec wait-time (?). Does anyone have any favourite EQ settings for the MKE300 that I could try as a starting point?
4) Do I then need to "normalise" the audio to a particular level, and if so, what level and how? My final output formats are DVD (MPEG2) and miniDV tape (will also be used as a master for VHS copies).
5) Re-import the processed .wav file to LE and replace original audio tracks.
6) Dump to master tape, make DVD, distribute to grateful public...
I want to put music under the intro and end sequences, reducing the volume of the "live" sound track accordingly. Should I do this at stage 1 or after stage 5? I think it should be at stage 1, but maybe not include the music in the exported .wav file, only the reduced live sound-track. Does that make sense? What about a voice-over track? Should it be processed separately or together with the live sound?
Does anyone have much experience of GoldWave? Is there much to choose between it and Audacity? Is there something better at the free/very cheap end of the market. It was suggested to me that paying for a better quality VST plug-in would be better value for money than paying for an editing program per-se. Is this good advice? If so, what plug-in(s) are recommended for my sort of work?
What I really want to avoid is messing up the sound, which is why, so far, I've not played about with it. However, if I can make it better...
I know I'm asking a lot, and maybe I should buy a book (Jay Rose is mentioned often around here). I've been looking for FAQ pages and the like, but not found much - if you know of something that covers my questions, please point me at the right the sites.
If you've read this far - thanks for your patience. I look forward to reading your replies....
