A note: Better Audio Narration Recording

    Hi All,
    I happen to be a one-time recording studio tek and also spent 8 years on the road as a rock band touring audio manager (long ago - Jefferson Starship and Hot Tuna). Yes, lots of thrills & spills.

    I hear many voice recordings online spoiled by poor recording technique. So, here is some advice...

    One of these days, I gotta make this and more into a YouTube vid and a little ebook on audio for webmasters. Meantime, here are some quick notes which might help you:

    Audio recording for the Web
    1. Use a good mic at a fixed distance, very close to your mouth. I prefer the excellent Radio Shack Model: 33-3012 Catalog #: 33-3012. It's a headset/boom mic copied from a good design Britney Spears used to use on stage. Don't forget to turn off the battery when you're done!

    2. Avoid "P-Popping" ("plosive sounds"), by:
    A. Adding more (porous) foam rubber around that mic.
    B. Positioning the mic well below your mouth - so that your plosive breath bursts go over it (that jet of turbulent air is rather directional and sound is not), but the sound still reaches it. Test by recording "Popeye paid for popping popcorn", while you adjust things.

    3. Invest in a good sound card, like the fine Soundblaster "X-Fi" from Creative. It includes a great software audio mixer to help you equalize your voice sound and filter out noise and hum. You may be surprised at how good your voice can sound with a bit of boost here and cut there in the voice spectrum.

    Try cutting the ultra lows (to remove room noise and electrical hum) below 125Hz. Play with the bass (125 Hz to 500Hz) and add intelligibility and snap with a boost to the highs (3,000Hz to maybe 6,000 or 8,000Hz).

    4. I use the fantastic Camtasia Studio software to make my vids, record my audio and to do minor edits - usually all that's needed.

    5. For serious audio noise reduction and complex audio editing, I really like the "Acoustica" program from www.acondigital.com. Careful, there are several sites called "acoustica".

    6. No need to constantly stop and start your recording when you find yourself saying "uh" and "ah" and such. Whenever you flub it, just be quiet for 3-4 seconds to create a bit of recorded silence, then repeat that part of your narration. It's easy to locate those silent bits later and just delete the unwanted parts in between.

    7. In Camtasia Studio, you can zoom in on the sounds and easily delete or attenuate undesirable breath sounds, lips smacking, etc. Some subtle breath sound is good for a natural relaxed rhythm, but certain types can be annoying and unprofessional.

    Hope this helps...
