What does sample rate (e.g., 44.1 kHz) determine in digital audio?
Answer: How many times per second the signal is measured
Sample rate is the number of amplitude measurements taken per second, setting the highest reproducible frequency.
What does bit depth (e.g., 24-bit) primarily affect?
Answer: The dynamic range and noise floor of the recording
Higher bit depth increases dynamic range and lowers the quantization noise floor.
Two interfaces are connected digitally via S/PDIF. Why must their sample clocks be synchronized?
Answer: To prevent clicks, pops, and dropouts from clock mismatch
Mismatched clocks cause sample slips that produce clicks and pops, so one device must be the clock master.
What is 'word clock' used for in a digital studio setup?
Answer: Synchronizing the sample timing of multiple digital devices
Word clock provides a master timing reference so all digital gear samples in lockstep.
An insert point on a mixer or interface channel lets you do what?
Answer: Patch an external processor into the channel's signal path
An insert breaks the signal path so an outboard processor like a compressor can be patched in and out.
What is the main difference between an aux send and an insert?
Answer: An aux send taps a parallel copy; an insert interrupts the path in series
Aux sends create a parallel feed for effects like reverb, while inserts place a processor directly in the signal path.
Why is 24-bit/48kHz a common recording standard over 16-bit/44.1kHz for new productions?
Answer: It offers more dynamic range and headroom for editing
Higher bit depth gives more headroom and a lower noise floor, which is valuable during mixing and processing.
