This can include the audio from your DSLR camera, video game console, or gaming computer, for instance. Streamer X HDMI (Audio): This input includes any audio that is sent into your Streamer X via the HDMI In connection. Streamer X Main: This is the primary audio stream from your Streamer X and includes either the XLR microphone, instrument, headset microphone or wireless microphone system connected to your Streamer X. When connected, the following devices will be available as input devices on your computer: Note: It’s important you use the included USB-C cable for this port, or alternatively a USB-C cable that supports SuperSpeed data transfer, as this is required to transmit the video feed.
It can also be used to power the Streamer X if the power supply isn’t connected, provided your device can supply the appropriate level of power. Instruments such as the guitar, ukulele and mandolin are designed so that the strings can be fretted and therefore made shorter, thus raising the pitch.This is the Streamer X’s primary USB port, and when connected, is used for sending and receiving video and audio data to your laptop or desktop computer. Plucked instruments, such as the harp, have strings that vibrate much like the piano. Stringed instruments rely on standing waves to create music. The strings are attached to a special wooden sound board, which translates the string vibrations into vibrations in the air. It has just the right energy to make that particular string swing up and down. Most of these waves quickly fade out, but one wave just happens to ‘fit’ on the string. The vibrations are waves, and they move down the string, echo back off the post at the other end and race back and forth. When the hammer strikes the string, the blow sends a burst of energy into the string and causes it to vibrate in many different ways. The pitch of the note depends on the tension, length and thickness of the string.īut why does a strike from a hammer cause the string to vibrate in this way? The hammers in a piano are all nearly the same, yet each string sounds a unique note. The string vibrates much like when a skipping rope is stretched and both ends are fixed (held tightly).
The simplest way that a string can vibrate is known as the fundamental frequency. When a string on a piano is struck by the hammer, the specific note that is made depends on the length, thickness and tension of the string. Each note on the piano makes a specific sound due to standing waves. To understand resonance, it is important to understand why a stretched string makes a specific note. When the vibration from one object causes another object to vibrate, it is called resonance. When you stop singing, you can hear the piano sounding the same note. If you press the sustain/damper pedal on a piano and sing a note, the strings in the piano that make the same note that you sing will vibrate. If the dampers were not in place, the piano would softly repeat any sound that comes in contact with it. It’s important for the piano to have dampers so that the piano strings can be kept quiet. The sustain/damper pedal lifts all the dampers at the same time to allow the strings to vibrate freely and the notes to keep sounding after you take your finger off the key.
