| The decibel (dB) scale used for SPL is logarithmic. | True |
| Frequency in a sound wave determines its perceived ______. | Pitch |
| Which statement about sound traveling through a vacuum is correct? | It cannot travel through a vacuum |
| In SPL measurements, 0 dB is referenced to ______. | The threshold of human hearing |
| For intermediate bounces between recording and final masters, it is recommended to use ______. | 32-bit floating point at the recorded sample rate |
| In sound, amplitude is perceived by our ears as ______. | Loudness |
| In audio, the unit dB is used primarily to represent ______. | Level or Volume |
| Sample rate refers to ______. | How many times per second an analog signal is measured |
| A higher amplitude sound wave corresponds to a ______ sound. | Louder |
| In sound, frequency is also known as pitch. | True |
| The sample rate determines the highest possible frequency captured in digital audio. | True |
| Timbre is the quality of sound that differentiates two sounds when they have the same ______. | Frequency and amplitude |
| Higher amplitude in a sound wave is perceived as lower loudness. | False |
| The decibel scale is ______. | Logarithmic |

| What is a Digital Audio Workstation (DAW)? | Software used to record, edit, and produce audio |
| Ribbon microphones are a type of condenser microphone. | False(dynamic microphone) |
| Which statement about RCA cables is TRUE? | They are unbalanced and commonly used in home A/V and DJ setups |
| Lavalier microphones are popular because they are unobtrusive and can be positioned close to the mouth. | True |
| Which is TRUE about USB in modern audio devices? | USB can deliver audio data, power, and MIDI (MIDI over USB) |
| Boosting the gain of a weak recording will increase the signal but not the noise floor, improving SNR. | False |
| Which statement about TRS cables is TRUE? | TRS can be balanced for mono, or carry stereo (unbalanced) depending on use |
| A DAW is hardware that converts analog signals to digital signals. | False |
| Good signal-to-noise ratio occurs when the signal is strong relative to the noise floor. | True |
| Which is a common application for condenser microphones? | Ambience and room recording |
| What is the primary role of an audio interface? | To bridge analog and digital audio by providing A/D and D/A conversion and mic preamps |
| Which microphone is typically omnidirectional, small, and worn on clothing for interviews or presentations? | Lavalier microphone |
| Which statement about S/PDIF is CORRECT? | It is a digital interface available in optical (Toslink) and coaxial (RCA) forms |
| Which statement about ribbon microphones is TRUE? | They are delicate and can be damaged by wind or very high SPL |
| What do MIDI cables transmit? | Event messages (performance data), not audio signals |
| RCA cables are balanced and can be run very long without interference concerns. | False |
| Dynamic microphones have lower sensitivity than condensers and can handle high SPL without distortion. | True |
| Which cable is unbalanced, often called a guitar cable, and should be kept short? | TS (tip sleeve) |
| Which microphone connects directly to a computer thanks to a built-in analog-to-digital converter? | USB microphone |
| Which microphone type is known for capturing sound in great detail with a crisp, open, and airy high end? | Condenser microphone |
| RCA cables are balanced and can be run very long without interference concerns. | False |
| Which microphone type is most rugged and ideal for loud sources like drums and guitar amps? | Dynamic microphones |
| Balanced cables use two conductors plus a ground to cancel out noise. | True |
| Shotgun microphones primarily pick up sound from behind the microphone. | False |
| Inside your DAW, an ideal average level per track during mixing is typically: | -12 to -18 dBFS |
| Which statement about XLR cables is CORRECT? | They are always balanced and suitable for long runs |
| USB microphones can remove the need for a separate audio interface by including a built-in A/D converter. | True |
| What is a key advantage of SpeakOn cables in live sound? | They lock in place and handle higher currents for speaker connections |
| When setting input gain for the loudest section, where should peaks land to avoid clipping and leave headroom? | About -12 to -14 dBFS, staying below -10 dBFS |
| Good signal-to-noise ratio occurs when the signal is strong relative to the noise floor. | True |
| Sound is a form of ______. | Energy |
| Which microphone features a narrow pickup pattern designed to capture sound directly in front from a distance? | Shotgun Microphone |
