Which microphone for a podcast? USB, XLR and number of speakers

The right question: who is speaking, where and on which device?

Before looking for the best microphone, describe your situation: one person at a desk, two people in the same room or remote guests. Add your computer or phone model, the available connectors and the usual background noise. These constraints are more useful than a universal ranking.

This guide explains technical choices using manufacturers’ documentation. It does not present equipment tests or product rankings. We do not recommend a model solely because of its brand or popularity.

USB or XLR: compare the whole setup

A USB microphone includes the conversion needed to send a digital signal to a compatible device. An analogue XLR output requires a suitable interface or recorder. Some microphones offer both outputs. The relevant cost therefore goes beyond the microphone’s price.

For a solo pilot on a computer, a simple setup is often easier to install and reproduce. An interface becomes useful when your specific needs justify its inputs and controls.

• With USB: check the compatible operating system, cable, power requirements and application.
• With XLR: include an interface or recorder with enough inputs, the cables and the power requirements.
• In either case: allow for a stable stand and a way to monitor the sound through headphones.

Dynamic or condenser: a separate choice from the connector

Dynamic and condenser describe how sound is captured, not the connector used. A condenser needs power for its electronics, often phantom power for an XLR model. A passive dynamic microphone does not. Always check the requirements of the specific model.

Do not assume that a dynamic microphone removes room noise. Placement, distance, recording level and acoustics still matter. Before replacing your equipment, try recording closer to the microphone in a less reverberant room and compare by listening.

Two people: think about separate tracks

Separate tracks let you adjust one voice’s volume or remove noise on just one track. An interface with several sockets does not guarantee that your software receives each input separately: check how the whole setup handles multitrack recording.

Connecting any two USB microphones to the same computer is not a universal solution. Combining audio devices depends on the operating system and can cause synchronisation problems. Compatible setups exist, but their documentation does not apply to every USB microphone.

Improve the room and make a test recording

Limit noise sources, move away from a window facing a busy street and prefer a furnished room. Curtains, rugs and clothes reduce some reflections. Stabilise the microphone, avoid knocking the table and find a position that keeps the voice consistent.

• Record a short passage at your usual speaking volume.
• Listen to the voices and background noise through headphones.
• Check louder passages: clipping is difficult to fix afterwards.
• Run a test with all the people and devices you plan to use.

Separate the equipment budget from the hosting budget

Equipment is generally an upfront purchase; hosting is often a recurring expense. As a budgeting method, list the microphone, cables, stand and interface separately, then twelve months of hosting. A microphone discount does not reduce the subscription. A more expensive subscription does not guarantee better sound and does not replace a carefully made recording.

Our comparison tool calculates audio hosting costs, not equipment costs. Use it to complete your budget once you have defined the number of shows, monthly production and any private distribution needs.
