BUFFER SIZE
How many samples your interface collects before handing them to the CPU. Small buffers mean low latency and more dropouts; big buffers the reverse.

Key takeaways
- How many samples your interface collects before handing them to the CPU.
- Small buffers mean low latency and more dropouts; big buffers the reverse.
- Small buffers mean low latency but heavy CPU load and dropouts; large buffers mean stable playback but delay that makes performing awkward.
- 128 samples for tracking, 512 or 1024 for mixing.
- Watch out: leaving the buffer at 64 through the whole project.
Quick checklist
- Can you define buffer size in one sentence without looking?
- Can you point at buffer size in a real session, mix or contract?
- Have you tried the practical move above at least once?
- Would you catch the common mistake before it costs you a take?
- Have you opened one of the primary sources below rather than a forum thread?
BUFFER SIZE IN DEPTH
The buffer is how many samples your computer processes in one chunk. Small buffers mean low latency but heavy CPU load and dropouts; large buffers mean stable playback but delay that makes performing awkward.
How it works in practice
128 samples for tracking, 512 or 1024 for mixing. Changing it per stage is a normal part of the workflow, not a compromise.
The mistake people make
Leaving the buffer at 64 through the whole project. It burns CPU for no benefit once you stop recording live parts.
WHERE BUFFER SIZE SITS
Buffer size belongs to production and recording in the Sampled music glossary. Studio words: what the gear does, what the engineer is asking for, what the session sheet means.
TERMS THAT DEPEND ON BUFFER SIZE
- Latency
The delay between playing something and hearing it back through the computer. Set by buffer size and interface drivers.
