Principles of audio and sound technology Flashcards
How do live room acoustics affect recording?
Room size, absorption, reflection, and diffusion impact the sound captured in recordings, influencing the clarity, spaciousness, and tone of the audio
How does room size affect recording acoustics?
Larger rooms generally have longer reverb tails and a more spacious sound, while smaller rooms produce shorter reverberation and a tighter, more intimate sound.
What is absorption in live room acoustics?
Absorption materials, like acoustic panels and foam, reduce the reflection of sound waves, minimizing unwanted reverberation and controlling the room’s acoustic properties.
How do reflections impact recording in a live room?
Reflections can enhance or detract from recordings, depending on their timing, intensity, and frequency content, affecting clarity, imaging, and perceived spaciousness.
What is diffusion in live room acoustics?
Diffusion scatters sound waves, reducing the buildup of standing waves and helping to create a more even distribution of sound energy within the room, resulting in a more natural and balanced sound.
What are isolation booths used for in recording?
Isolation booths provide controlled environments for recording vocals, drums, and amplifiers, minimizing bleed from other instruments or ambient noise, resulting in cleaner recordings.
How can natural and chamber reverb be utilized in recording?
Natural reverb from the room can be captured in recordings to add depth and ambience, while chamber reverb from dedicated acoustic spaces can be used to enhance or alter the recorded sound with different spatial characteristics.
What are the acoustics parameters in a live room?
the reverb tail, pre-delay time, and reverb time (RT60)
What is the reverb tail in recording acoustics?
The reverb tail refers to the decay of reverberation after the initial sound source has stopped, influencing the perceived size and character of the acoustic space in recordings.
What is pre-delay time in recording acoustics?
Pre-delay time is the duration between the direct sound and the onset of reverberation, affecting the clarity, separation, and intelligibility of the recorded sound by controlling the perception of distance and depth.
What is reverb time (RT60) in recording acoustics?
Reverb time (RT60) measures the time it takes for reverberation to decay by 60 dB after the sound source has stopped, providing information about the duration and intensity of the reverberant sound in a room
: How does signal path affect the effects heard on commercial recordings?
The signal path determines how audio signals are processed, affecting the application and intensity of effects, such as EQ, compression, and reverb, in commercial recordings.
What is the use of balanced connections in connectivity?
Balanced connections, such as XLR cables, help to prevent noise problems like hiss, hum, and rumble by canceling out interference picked up along the cable.
What are DI boxes used for?
DI (Direct Injection) boxes are used to convert unbalanced instrument signals into balanced signals, allowing them to be connected to balanced inputs on mixers or audio interfaces without noise interference.
