Reading this thread made me curious about the Motu4 and the problem with sampling rates. I know that I've experienced the popping if I had the sampling settings mixed up in my Behringer interface and they were easily fixed, so I posed the question to ChatGPT:

Is Motu4 usb interface capable of different sampling rates?

Yes — the **[MOTU M4] USB audio interface supports **multiple different sampling rates** for recording and playback, not just a single one. Specifically, it can be set to any of the common audio sample rates from **44.1 kHz up to 192 kHz**, giving you flexibility depending on your project needs.

### Supported Sampling Rates

The MOTU M4 can operate at the following standard sample rate settings:

* **44.1 kHz**
* **48 kHz**
* **88.2 kHz**
* **96 kHz**
* **176.4 kHz**
* **192 kHz**

### What This Means for You

* **Lower rates** (44.1 kHz, 48 kHz) are great for most music and multimedia projects and use less CPU and disk space.

* **Higher rates** (88.2 kHz, 96 kHz, 176.4 kHz, 192 kHz) can provide increased audio detail and are used in high-fidelity, professional recording applications — though they require more processing power and storage.

You can select the desired sample rate in your DAW or in the audio settings of your operating system once the interface is connected.
