What buffer size should I use?

Start at 256–512 samples for production. For live input monitoring, try 128–256 if your system stays stable.

How do I stop clicks and pops?

Use ASIO drivers, raise the buffer, disable CPU throttling with a high-performance plan, update drivers, and check problematic plugins.

Why does Bluetooth audio lag?

Bluetooth codecs add significant latency (SBC/AAC). For real-time work, use wired headphones or a low-latency wireless system with aptX LL/Adaptive (interface-dependent).

Quick checklist

Use ASIO drivers

Select FL Studio ASIO or your interface’s native ASIO in Options → Audio.

Balance buffer vs. latency

256–512 samples for production; lower only if stable for live input.

Keep rates consistent

Set 44.1–48 kHz in both Windows and FL Studio to avoid resampling.

Step‑by‑step optimizations

1) Switch to ASIO

Options → Audio settings → Device: choose FL Studio ASIO or your interface’s ASIO. WASAPI/DirectSound add latency.

2) Tune buffer size

Start at 256–512 samples. Raise if you hear clicks; lower only for real‑time monitoring when the system allows.

3) High‑performance power plan

Windows Power Options → High performance or Ultimate Performance. Disable CPU parking and sleep for USB devices.

4) Fix USB audio dropouts

Device Manager → USB Root Hub → Power Management: uncheck “Allow the computer to turn off this device”. Prefer rear motherboard ports.

5) Update drivers

Install the latest audio interface driver. Update GPU and chipset drivers; keep Windows up to date to reduce DPC latency.

6) Tune FL Studio settings

Multithreaded processing (Generators/Effects)
Smart Disable for idle plugins
Mixer Resampling: keep moderate while composing
Prefer 64‑bit plugins; avoid unnecessary bridges

Target latencies: 5–12 ms for live input (if stable), 12–20+ ms for mixing. Stability first.

Troubleshooting

Clicks/pops under load

Raise buffer size, freeze/bounce heavy tracks, lower resampling during composing, and check for CPU‑hungry plugins.

High DPC latency

Update network/Wi‑Fi and GPU drivers; try disabling problematic devices (temporarily) and test again.

USB interface disconnects

Disable USB selective suspend; use short, quality cables; avoid hubs; try different motherboard ports.

Bluetooth delay

Bluetooth adds large latency (SBC/AAC). Use wired monitoring or a low‑latency audio interface.
