Pianos and Mics - No Simple Solutions
Just as with most acoustic stringed instruments, the bulk of the sound is
produced by the sounding board to which the strings are attached.
In guitars and violins, it's the top of the instrument; in pianos,
it's the sounding board. You don't mic the picks, the bows, or the hammers -
they produce very little sound.
There are several considerations when placing mics for piano recording.
Foremost, will the instrument be recorded by itself, or with other instruments
playing at the same time? Those two situations require different mic
techniques. Is it a grand piano or an upright piano?
Each requires different mic techniques. Finally, where will the recording
take place? That may also require different mic techniques.
If the purpose of the recording is accuracy, and you're micing a
solo concert grand piano, then you'll need some good, small diaphragm
condensor mics, placed some distance from the piano, usually around 6 to 8
feet away. You can use an x-y setup for cardioids, or a wider spaced ORTF
setup with omnis or cardioids.
The piano lid is used to direct some of the sound towards the mics.
IF the piano is part of a group of instruments, you can get better isolation
by micing the underside of the instrument, using a sightly wide spacing with
omnis or cardioids. Mics placed inside the top of the instrument can also be
used,but it's harder to achieve a good balance or isolation since the piano
lid will also reflect sounds from the other instruments into the mics.
Large diaphragm mics can also be used, but the response changes as
the sound enters from different angles and the larger mics add coloration
(which can sometimes add an unexpected richness to the sound).
Upright pianos should be miked from the back of the instrument, but try to
avoid having the soundboard too close to a wall. The distance from the wall
will create a standing wave which will interfere with the sound.
If the piano has to be near a wall, angle the piano so that it doesn't sit
parallel to the wall. Be especially attentive to a ringing sound when
micing upright pianos.
This ringing is caused by resonances within the piano, and usually can be
solved or reduced by moving the mics around till you find a dead area,
free of the ringing.
Just as with a concert grand, close micing is not advised,
but since an upright piano is usually part of a group, it's not possible to
mic from a distance and still have isolation.
To sum it up, first choices for recording a piano would be small omni
or cardioid condensor mics, but don't be afraid to try large condensors,
ribbons, or dynamic mics (if that's all you have).
Mic from a distance if possible. Second choice would be under the piano,
and finally, from the top of the piano, but watch out for ringing and
reflections from that position.

: 錄音室需求
: 目前已知大振膜低頻較好, 小振膜高音較亮 (不知有沒有誤)
: 以及大振膜較容易受環境影響外
: 仍無法確切的知道哪一種錄出來的音色是自己所要
: 不知道有沒有前輩能夠提供更多大振膜與小振膜電容式麥克風的錄音經驗
: 無論是鋼琴,吉他,弦樂,木管樂器的經驗皆可
: 如果能有錄音的比較更好
: 非常急知, 小的在這裡跪謝了
