Sample Rate
Definition
The number of audio samples captured per second in a digital audio system. Common rates include 44.1kHz (CD standard), 48kHz (video/broadcast standard), and 96kHz (high-resolution audio). Higher sample rates increase file size and CPU usage proportionally.
Context
The choice of sample rate affects file size, CPU overhead, and Latency. The Nyquist theorem dictates that a sample rate captures frequencies up to half its value (e.g., 44.1kHz captures up to ~22kHz). Recording at higher sample rates is debated in the community — some engineers prefer 48kHz or 96kHz for headroom during processing, while others maintain that 44.1kHz is sufficient for most purposes.
Community Debate: Which Sample Rate?
The recording-talk channel reveals a pragmatic consensus with some entertaining outliers:

“I think everyone should come to their own conclusions but in my research, I found that 96 is in fact a higher number than both 44 and 48. I’m sure there’s more to dig into there, but that’s what I’ve come up with thus far.”
cian riordan (2022-07-18)
“Most sane, reasonable people would say no — there’s no audible difference. But then you have very successful record makers who have un-challenged opinions rooted in magic and mystique who swear that a difference exists. I find it best to make these decisions on program material. If you’re doing anything exclusively for CD, there’s merit in sticking at 44.1 kHz to save a conversion step — but 48kHz makes more sense in the modern record making era because streaming services accept it and it’s the standard for TV/film.”
- 44.1kHz — CD standard, avoids sample rate conversion for CD delivery
- 48kHz — Video/broadcast standard, Calvin Lauber: “I record at 48 cause it’s a little more than 44 and I’ve never heard a difference between any of it”
- 96kHz — Some engineers prefer for headroom during pitch/time manipulation
- Higher sample rates help with cleaner time and pitch shifting — This is the most practical argument for recording above 44.1/48

“‘Gang vocals only sound right at 44.1kHz’ — JJP”
Slow Hand noted that despite the humorous sample rate takes, “JJP is a goldmine of insights into production and engineering.”

Channel: newbie-questions — Date Range: 2021-02 to 2026-02 Definitive answer (59 reactions — most-reacted message in channel, pinned): Nomograph Mastering (2022-10-22): “If I was asked ‘What sample rate should people make records at in 2022?’ And was forced to choose then the answer would be 48k. Film and TV prefer it, converters handle it efficiently, and there’s no audible benefit to higher rates for most record-making.” See also: Mastering Basics, newbie-questions Channel Summary
