I recommend selecting ASIO devices as it makes the DAW interact directly with the interface, cutting many intermediary steps to make the process faster. Firstly, you have to ensure that the correct audio device is selected. Let’s now understand how you can resolve the buffer underruns issue. It is primarily caused by CPU overload or system optimization issues.

So you will hear a crackling noise when the Buffer runs out before enough audio is made. The reason for doing so is that the CPU has enough time to manage any spikes in audio that it can’t handle in real time. The Length of these segments is called Buffer Length. So small segments of these renders are sent to the audio interface ahead of time. When you hear the output in FL Studio, the audio is rendered a few milliseconds before you hear it.

Firstly, let’s talk about buffer underruns. Let’s explore all the reasons in-depth and find solutions to them. 3 Readings that you may like: Why Audio in FL studio Makes Crackling Noise?įL Studio’s audio makes crackling noise due to overloading the DAW with many third-party plugins or samples, buffer underruns, or setting a low buffer rate, buggy plugins, not having the correct audio settings, running the DAW with other software like OBS, Zoom, etc., or working on high sample rates.
