Less listening fatigue
When two voices share a point in space, the brain does the separating. Over an hour that is real effort, and it shows up as listeners drifting rather than as complaints.
Three voices in mono all arrive in the middle of your listener's head. Place them left, centre and right and following the conversation stops being work. Drop one track per speaker, drag their dots apart, export the episode.

FlatEvery voice summed to the centre, the way a normal mix delivers it.
PlacedThe same tracks and the same levels, each at its own angle.
Switch mid-sentence, while it plays
Hearing separates sources by direction before it separates them by tone. That is what lets you follow one person across a loud room, and it is exactly what a mono dialogue mix takes away.

Interruptions and talkover are the hardest part of a panel episode to edit. Placed apart, two people speaking at once stay separately intelligible instead of turning into a smear.
No processing on the voices themselves. Your levels, your edit and your compression all survive, and the file you get back is a normal stereo WAV.
Placing, previewing, the A/B and a full-quality export of the first 3 minutes. No account, no watermark, no time limit on the tool itself.
Exporting a full-length episode: £3, once, with no subscription. The pass stays open for 48 hours, so noticing a mistake after you downloaded the file does not cost you again.
The work happens on your machine, so the tool costs nothing to run and can stay open. The charge sits at the point where you have finished something and want to publish it, which is the only moment paying is obviously worth it.
Because your hearing separates sources by where they are before it separates them by what they sound like. Three mono voices arrive at the same point between your ears, so the only clue to who is talking is timbre, and your brain does that work for the whole episode. Place the same three voices left, centre and right and the work stops. It is the cocktail-party effect, the same thing that lets you follow one conversation in a loud room, and it is audible to anyone on ordinary headphones.
Yes, and most podcasters already have them. Anything recorded on a multitrack recorder, a remote recording platform, or an interface with one microphone per person gives you one file per voice. A finished stereo mix cannot be used, because the voices are already summed together and there is nothing left to place independently.
Each voice has a start offset in seconds. Set it once per track and everything lines up against the same episode clock. If your recording platform already exports aligned tracks, leave every offset at zero.
No. Decoding, preview and the final render all happen inside your browser through the Web Audio API. Files never leave your machine, which is also why an hour-long episode renders faster than it plays: there is nothing to upload and nothing to wait for.
It stays perfectly listenable, but most of the separation collapses. Binaural placement works by recreating the small timing and level differences between your two ears, and over speakers both ears hear both channels. Since the large majority of podcast listening happens on headphones and earbuds, that is usually the right trade. Check a speaker playback before you publish if your audience is unusual.
Placing, previewing and comparing are free and unlimited. A free export gives you the first 3 minutes at full quality with no watermark, which is enough for a trailer or a clip. A full-length episode export is £3, one payment, no account and no subscription, and it stays open for 48 hours so a re-render after a late fix costs nothing.
The binaural rendering here is the one that drives the DJ decks and the 8D renderer. In those it moves; here it holds still, because a conversation only benefits from knowing where everybody is sitting.
