Speaker positions
How many speakers you can drive.
Wavelinkth sends each speaker position its own audio, so the question is simply how many separate outputs your PC has. Here is the whole arithmetic, and what it costs to add more. We don't sell hardware — the links go straight to ordinary listings, and we make nothing either way.
START HERE
Your PC's own output — 2 positions
The speakers already plugged into your PC become front left and front right. Nothing to buy, nothing to configure. If you only ever do this, Wavelinkth still works — it just has two positions to place sound between.
The cheap upgrade
USB audio adapters — 2 positions each
A USB audio adapter is a thumb-sized dongle with a headphone socket. Windows treats each one as a separate output, so each adds two more speaker positions. Three of them gets you a full six-position setup for around $24.
Each one needs a speaker with a socket to plug into — check the port list below before buying.
One only
Bluetooth speakers — 1 position
Pair as many as you like; your PC's radio will still only play through one of them. Windows shows the others as connected while refusing to send them audio, and which one it picks can change between sessions. Wavelinkth tells you plainly which speaker is unavailable and why, instead of failing silently.
Treat Bluetooth as one position, and add the rest over USB.
Check first
Which port your speaker has
3.5 mm aux — straight into an adapter. Nothing else needed.
RCA, red and white — works with a 3.5 mm-to-RCA cable.
USB-C or USB-B carrying audio — the best case. Plug it into the PC and it becomes its own output: no adapter, no radio, no sharing.
USB-C for charging only — no audio path. Common on recent portable speakers, and the one to watch for.
Optical or HDMI — soundbar territory. Most also have aux or RCA; use that instead of buying a converter.
Bluetooth only — one of these, no more. See the Bluetooth note.
Not sure which you have? Plug it into the PC and press Rescan devices in Wavelinkth — if a new output appears, it carries audio.
Optional
Spare phones and tablets
Any spare screen opens a page in its browser and becomes another speaker position — and, unlike an adapter, a light as well. Nothing to install. That drawer of old phones is the cheapest upgrade you own.
Two builds
What people actually end up with
Four positions, ~$8. PC output for the front pair, one USB adapter behind you for the rear pair. This is the sweet spot — real directional sound for the price of a sandwich.
Six positions, ~$24. Three adapters: front, sides, rear. Beyond this the room matters more than the count.
