Stuttering audio — short pauses or a robotic, choppy sound — is a close cousin of crackling, but the cause and fix lean slightly differently. Here's the distinction and what to check.
What makes stuttering different from crackling
Crackling tends to be a brief click from one short buffer underrun. Stuttering is usually a longer gap — the buffer ran completely dry for a moment, often because of a sustained CPU or disk bottleneck rather than a single brief spike.
Buffer size and exclusive mode, explained simply
A larger buffer gives the system more cushion before a delay becomes audible, at the cost of slightly higher overall latency. Audio exclusive mode can also help by giving your audio software direct, uncontested access to the device instead of sharing it through Windows' mixer.
A practical fix checklist
Increase your DAW or audio software's buffer size first — it's the fastest test. Then check for background processes competing for disk or CPU (cloud sync, antivirus scans), and run a DPC latency scan during playback to rule out a driver-level cause.
