Music Tech Midterm

Sound Vibrations of matter propagated by longitudinal pressure waves
Music Technology the practical application of knowledge to music
Frequency The number of times a wave completes a cycle per one second(measured in Hertz/Hz)
Phase How far a wave is through its cycle before it repeats again(measured in degrees)
Amplitude Refers to the intensity or particle displacement of a sound wave (measured in dB)
Timbre Quality given to a sound by its overtones
Overtones Frequencies that vibrate above the fundamental frequency that do NOT include the fundamental frequency
Define the limits of the frequency range of human hearing 20Hz-20000Hz
Define the threshold of human hearing and pain 0dB SPL to 120 dB SPL
What band of frequencies are human ears most sensitive to? 4,000 Hz
Identify microphone types Condenser, Ribbon, Dynamic
Condenser Characteristics Requires phantom power (external +48V)
Ribbon Characteristics Very fragile, naturally bidirectional
Dynamic Characteristics Very robust and sturdy, typically used for live performances
Identify microphone polar patterns Cardioid, Bidirectional, Omnidirectional
Cardioid Heart shaped, picks up sound from all directions
Omnidirectional Picks up from all angles
Bidirectional Figure 8 shape, picks up sound from front and back
Identify Cable Types Unbalanced and balanced
Unbalanced cables RCA, TS (2 wires, hot wire and ground wire)
Balanced cables XLR, TRS (3 wires, hot, cold, and ground wires)
Identify the audio levels Mic, line, speaker
Mic level Small electrical signal when coming out of a microphone before the preamp
Line level The level of signal as it leaves a mixer
Speaker level Signal level of amplified signal by an active speaker or external amplifier
Difference between mono and stereo mono is a one channel signal, stereo is a two channel signal between left and right
Identify basic elements of a mixer input, preamp, EQ, fader, master, outputs
Preamp Gain knob, boosts mic to line level
EQ Boosts or cuts different frequency bands in a channel's signal
Fader Control each channel's volume in the overall mix
Active Speakers Has a built-in amplifier and plugs into a wall outlet
Passive speakers Does not require a wall outlet, Needs an external amplifier
Compressed files MP3, AAC, OGG, M4A - take up less space, easier to stream and distribute/Loss of quality
Uncompressed files WAV, AIFF - No quality loss, takes up more space
ADC/DAC Analog to Digital Converter/Digital to Analog Converter - both found in most computer sound cards and audio interfaces
Sample Rate The number of digital snapshots/samples an ADC takes of incoming analog signal. Number of samples per second. Most consumer audio such as CDs use 44,100Hz sample rate.
Nyquist frequency Highest recorded frequency at a given sample rate = (sample rate/2)
Preferred sample rate When working with audio - 48,000Hz
Bit Depth Refers to the number of different amplitudes that can be recorded. Higher the bit depth, higher the dynamic range., and further the signal from the noise floor. With digital audio, we want to use 24 bit, but consumer audio uses 16 bit

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
