Piano recording--sort of long

Ric,

The Earthworks mics are great and will be the most precise...but probably
not recommended if you want to do it cheaply.  If your intention is only to
record some examples of pretty good quality, you don't have to spend that
much.  If you want truly excellent quality, get them.

A recording made with your built-in laptop microphone will probably sound
closer to hearing the piano over the telephone than just about any external
mic you can get.  Boundary mics are good if you will always have something
to put them on.  Also, check out the miniature omni condenser mics from
core-sound.com.  They can handle the high SPL of a piano very well.  You can
always find places to clip them inside the piano for a dry sound, affected
little by the room you are in (helpful if you just want the sound of the
piano or maybe a dry jazz piano sound, but not a good technique for
classical or other music).

As far as mic positioning goes, you will have to experiment.  Any recording
engineer will tell you that the science of mic placement only gets you so
far, and beyond that you have to use your ears.  Sometimes moving the mics a
couple of inches will change the sound dramatically.  Michael G.'s
suggestion for placement is a good starting point.  Sometimes I find that
moving them to the right of the curve, toward the bass strings (still about
6 feet away), gives a more balanced sound.  Sometimes the dampers and the
room are both so noisy that you'll have to mic from underneath the
soundboard...as a last resort, IMO.

All of this advice would be different if you were talking about recording
classical music complete with the reverb of the room, fully developed sound,
etc., but for what I think you are wanting to do (just record the sound of a
piano for others to hear and help diagnose problems) this should work well.

Also, check out Audacity for pretty good free audio editing software.
Start, like Doug said, with a good sample rate (44.1khz is CD quality) and
compress to mp3 later for posting to the list.

I hope that's helpful.

Take care,
Brandon Robertson
