How to choose the best synchronizers and clock generators
Clock Stability/Jitter
This is the big one. Low jitter means a clean, rock-solid clock signal; high jitter introduces timing errors that sound like flams gone wrong or a warbly synth. A clock with 10ns or less jitter is generally considered acceptable for most pro applications, but lower is always better.
Connectivity
Do you need Word Clock, S/PDIF, ADAT, MADI, or a combination? Consider your existing gear and future needs. Having multiple outputs is a huge plus for routing clocks to different devices.
Features (Word Clock, Pulse, LTC, Video)
Beyond just generating a basic clock, some units offer features like locking to Linear Time Code (LTC) for film sync or generating a pulse signal for triggering external devices. These can be invaluable for specialized workflows.
Resolution/Accuracy
Higher resolution (e.g., 24-bit vs. 16-bit) allows for finer timing adjustments and reduces rounding errors. Accuracy refers to how closely the clock adheres to a reference frequency - important for precise synchronization.
Ease of Use/Interface
A complicated interface can be a real pain, especially when you're under pressure in a live situation. Look for a unit with clear labeling, intuitive controls, and a display that shows critical information at a glance.
Buying guide
Look, timing is everything. Whether you're tracking drums with a click, syncing your vintage Juno to a modern DAW, or getting your whole band tight for a gig, a solid synchronizer or clock generator is the unsung hero of a good recording or performance. It's the glue that keeps everything locked, and a sloppy clock can ruin a perfectly good track or leave you feeling like you're fighting the band onstage. Let's break down what you need to know to pick the right one.
Don't cheap out too much here. A poorly built clock generator will introduce more problems than it solves. Entry-level units can be fine for basic bedroom recording, but if you're serious about tight timing, invest in something with a reputation for stability.
Watch out for units that advertise 'super low' jitter without backing it up with actual measurements - that's often marketing hype. Paying a little more for a unit with robust build quality and a clean clock signal is almost always worth it.

Questions
What's the difference between Word Clock and BNC?
Word Clock is the signal itself - the timing reference. BNC is the type of connector used to carry that signal. Think of it like HDMI (signal) and a Type-A connector (the plug).
Do I need an external clock generator?
Not always. Many audio interfaces have decent internal clocks. However, an external clock provides a more stable reference, especially when syncing multiple devices or dealing with noisy environments.
What does 'long-frame lock' mean?
It refers to the ability of a clock generator to lock to a reference signal even with a significant amount of drift or instability. Useful when syncing to older gear or less-than-perfect sources.
Can I use a drum machine as a clock source?
Yes, but be cautious. Some drum machines have notoriously inaccurate clocks. It's best to use a dedicated clock generator for critical timing applications.
My DAW says 'internal' - should I use an external clock?
If your DAW's internal clock is working reliably and you're only using one interface, internal is usually fine. But if you're syncing multiple devices or experiencing timing issues, try syncing to an external clock.
