Podcasting gear beyond the microphone
The microphone gets all the attention and accounts for maybe a third of whether a podcast sounds professional. What it plugs into, how it's recorded, and what the hosts hear while recording decide the rest. This is how Meros specifies podcast equipment for studios in Sydney.
01 — The hub
What an audio interface or podcast mixer actually does
Four jobs, bundled into one box. Understanding them separately is what makes the buying decision obvious.
It supplies preamplification — bringing a microphone's very low output up to a usable level cleanly. Cheap preamps add hiss at the gain levels dynamic microphones need, which is the most common reason a good mic sounds thin.
It converts analogue to digital. Modern conversion is good enough across the board that this is rarely the differentiator it's marketed as.
It routes: which inputs go to which recording tracks, what the hosts hear, and what a live stream receives. Routing flexibility is where dedicated podcast mixers pull ahead of generic interfaces.
And it provides monitoring — independent headphone mixes so each person can hear themselves and their guests at a level that suits them, which matters more for performance than most people expect.
02 — The recording decision
Multi-track vs mixed recording
The single most valuable technical decision in a podcast studio, and it costs almost nothing to get right at the start.
Multi-track recording
-
What it records: every microphone to its own separate track, kept independent through the whole session.
-
Fixing problems: one person's level, noise or cough can be corrected without touching anyone else.
-
Editing: cross-talk and interruptions can be cleaned up per speaker. Slower, but far more capable.
-
Storage: larger files, and a session to manage rather than one file.
-
Recommendation: the default for anything with more than one participant. The insurance is worth the extra step.
Mixed (single-track) recording
-
What it records: all microphones combined into one stereo or mono file at the moment of recording.
-
Fixing problems: any correction applies to everybody at once. A single bad input compromises the whole recording.
-
Editing: fast and simple — good when the episode ships essentially as recorded.
-
Storage: one small file, immediately publishable.
-
Recommendation: reasonable for solo shows, live broadcast, or a proven workflow with no post-production.
03 — What they hear
Monitoring
The most overlooked part of a podcast room, and the one that most changes how the hosts perform.
Everyone wears headphones — closed-back, so nothing leaks back into the microphones. Speakers in a recording room cause feedback and bleed, and there's no workaround worth attempting.
Hearing yourself is what regulates delivery. Without it people drift off-mic, speak too quietly, or over-project, and no amount of post-production restores a performance recorded blind.
Independent headphone levels matter once there's more than one person. A guest who needs the host louder shouldn't have to change what the host hears, and arguments about the mix waste recording time.
For remote guests, monitoring is also how the room hears them — routing the remote feed into the headphone mix without sending it back to the guest, which is what stops them hearing themselves echoed.
04 — Off-site
Remote guests
A remote guest is an audio source with its own room, and it usually becomes the weakest link in the episode.
The simplest route is a call brought into the mixer over USB or Bluetooth, with mix-minus applied — sending the guest everything except their own voice, so they don't hear themselves delayed. Any podcast-specific mixer handles this automatically; a generic interface may not.
The better-sounding route is double-ended recording: the guest records themselves locally while you talk, and sends the file afterwards. It removes call quality from the equation entirely, at the cost of asking something of the guest.
Purpose-built remote recording platforms do this automatically — recording each participant locally at full quality and uploading in the background — and are worth the subscription for any show with regular guests.
Whichever route, record the call audio as a separate track as a backup. It sounds worse, and it has saved more episodes than any other single habit.

Common podcast equipment mistakes
-
Recording everyone to one track, then discovering one guest was clipping the entire time.
-
Skipping headphones because the room feels awkward with them, and losing all control of delivery.
-
Using an interface with weak preamps behind dynamic microphones that need a lot of clean gain.
-
Forgetting mix-minus, so the remote guest hears themselves echoed and stops talking naturally.
-
Buying more inputs than the room will ever seat, or fewer than it already does.
-
Treating a remote call recording as the master rather than as the backup.
Podcast equipment FAQs
Do you need a podcast mixer, or just an audio interface?
For one or two people recording to a computer, a good audio interface is usually enough. A dedicated podcast mixer earns its place once there are more hosts, remote guests or live streaming, because it handles routing, independent headphone mixes and mix-minus that generic interfaces often don't.
How do you record remote podcast guests properly?
The best-sounding method is double-ended recording, where each guest records locally and the files are combined afterwards — remote recording platforms do this automatically. If the guest joins by call instead, use mix-minus so they don't hear an echo, and always record the call as a separate backup track.
What's the smallest podcast setup that still sounds professional?
One dynamic microphone per person, an interface or mixer with clean preamps, closed-back headphones for everyone, and multi-track recording — in a room with basic acoustic treatment. The room and the recording method matter more than spending more on any single piece of gear.
