Interfacing Linux: Apogee ONE (2009)

In 2009 Apogee released a USB powered single‑channel audio interface in a fingerprint magnet plastic enclosure. It featured a mono input, stereo output and built‑in microphone, as well as a multi‑function encoder knob. In 2021 it barely works with macOS and don’t even think about using it with Windows 10. Let’s find out if it knows how to Linux.

ALSA: You can control the Apogee ONE directly with alsamixer.

QasMixer: If you’re looking for a GUI.

JACK: Jack setup is straightforward but keep in mind it’s limited to 44.1/48K.

Pulseaudio: It’s not a sound card but you’re going to use it as one anyway.

LATENCY: While many kinds of audio latency metrics exist, one useful and well-understood metric is round-trip latency; the time it takes for an audio signal to enter the input of a device, get processed, and exit the output.

The Apogee ONE is a USB 1 device so don’t expect wicked-low latency. That said, it’s still serviceable for monitoring with a 128 buffer.

Apogee ONE: Round-trip latency @44100 Hz

Apogee ONE: Round-trip latency @4800HZ


If you are looking for an interface that can drive a SM7B, PR40, or Golden Age D2 on the cheap it’s a no brainer. There is absolutely nothing wrong with the original Apogee preamp as long as you can live with 48K limitation.
