什么时候用到pick-up

The pickup pattern is the area around the mic where sound can actually be "heard" by the microphone.斑竹能帮忙翻译一下么？

Microphone technique is largely a matter of personal taste—whatever method sounds right for the particular instrument, musician, and song is right. There is no one ideal microphone to use on any particular instrument. There is also no one ideal way to place a microphone.
Place the microphone to get the
sound you want. However, the
desired sound can often be achieved
more quickly and consistently by
understanding basic microphone
characteristics, sound-radiation
properties of musical instruments,
and acoustic fundamentals.
关于话筒拾音技术的，请斑竹翻译过来好么？

谢谢斑竹！
