The audio interface you need depends on one number: how many things you'll record at the same time. One singer or one guitar needs one input, a singer with a guitar needs two, a drum kit needs eight. Get that number right and the rest of the choice is easy, because almost all interfaces for home recording sound good today.
Of the 308 audio interfaces Thomann had in stock in October 2026, 240 connect over USB, and the median USB model costs $276. Thunderbolt, Ethernet and PCIe models are for bigger studios and cost several times more.
How many inputs do you need?
- One input: a single vocalist, a podcaster, a guitarist recording alone.
- Two inputs: vocals and guitar together, a stereo keyboard, two podcast guests.
- Four inputs: a small band recording live, a synth setup, a drummer with a few mics.
- Eight inputs or more: a full drum kit or a band in one room.

USB, Thunderbolt, Ethernet or PCIe?
| Connection | Models | Cheapest | Median |
|---|---|---|---|
| USB | 240 | $17 | $276 |
| PCIe | 14 | $141 | $955 |
| Ethernet | 16 | $218 | $1,462 |

Prices are Thomann's as of October 18, 2026. USB is enough for almost every home studio. Thunderbolt and PCIe cut latency further for large sessions, and Ethernet (Dante and AVB) connects interfaces across rooms in bigger studios and live venues.
Questions
Do I need an audio interface?
If you record a microphone or a guitar, yes. A computer's built-in input is noisy and adds delay. If you only record your voice for calls or podcasts, a USB microphone like the Audio-Technica AT2020USB-X is a simpler choice.
How much should I spend on an audio interface?
$100 to $200 covers one or two inputs from good brands. Spend more only when you need more inputs at the same time.
Is a more expensive interface better for sound quality?
Up to a point. Above a few hundred dollars you mostly pay for more inputs, better preamps for quiet sources and extra features, not for a different sound in a typical home recording.
