Acoustic Guitar Frequencies
If I were to play a recording of an acoustic instrument with a microphone, would have to change the freq?
This is for a scientific experiment. For example I record a guitar playing to the 440 Hz at home and the game coming back from a speaker in another microphone connected to your computer, how the different frequency from what I was recording directly into the microphone? it depends on the speaker / microphone? There is a general frequency increased / decreased? Thanks for your help and 10 pts for most helpful answer.
What yahooUser said. Remember, the purpose of a device is often to faithfully reproduce the sounds. If you record the guitar, and play it back, it would be ideal just like the sound of the guitar. If you save the recording and play it back, it would be ideal sound just like the first recording ... so as the guitar. yahooUser talked about the distortion, but there is something much more significant will happen if you copy a record to play it back through a speaker, and re-record with another microphone in a room. The mic does not just hear the sounds that come directly from the speaker, who will also hear the sounds that reflect on the walls and the ceiling and the floor. Each room has its environment "own" and that will be added to its record second generation. If you repeat the process several times, recording his umpteenth generation will begin to sound like the guitar was played in a giant echo chamber. In addition, each speaker and each microphone has a frequency response only ", which means he emphasizes certain frequencies and deemphasizes others. Unless the speakers and microphone four-digit price tags, the emphasis / deemphasis can be significant. You talked about playing a "The 440" on his guitar. But one point of view of signal analysis, even a single note of the guitar is really the sum of several sine waves of different frequencies. When you record that, through a microphone, and play it through a speaker, even if there is no harmonic distortion, is still the case that some of these frequencies will be strengthened, and others may be cut, resulting in a sound that can have a noticeably different quality "or" timbre "of the original.

Guitar string vibrating Photo Mugs Guitar string vibrating. When plucked, the string vibrates at a specific frequency, which determines the pitch of the note. The vertical lines on the fretboard (centre right) of the guitar mark where fingers should be placed to shorten or lengthen the vibrating part of the string. Shortening the string produces a note with a higher pitch, lengthening it lowers the note. The vibration of the string... |
