ISO tracks: why podcast producers ask for Scale

A mixed recording is fine when the finished show is meant to be watched exactly as it aired. It becomes restrictive when the live broadcast is also the source for an edited podcast. One cough, barking dog, or quiet guest is baked into the same track as everyone else, so fixing one person can damage another person’s sentence.

ISO tracks solve that specific post-production problem. Web Studio records a separate audio file for each participant alongside the main composite. Podcast producers ask for Scale because the extra tracks give them room to repair the conversation after the live show.

What a mixed track cannot do

Imagine a three-person panel. Guest A is making a useful point, Guest B coughs, and Guest C has background noise. In a single mixed track, those sounds occupy the same timeline. You can cut the moment, but you may also remove the useful sentence. You can lower the whole section, but then the host and the clean guest become quiet too.

Noise reduction and volume automation can help, but they cannot separate audio that was never recorded separately. If the error is baked into the mix, post-production choices are limited.

What ISO tracks give you

With ISO recording active, you get a dedicated track for the host and each Web Studio participant, plus the main composed recording. In a DAW, you can:

• mute one guest’s cough without muting the host;
• apply stronger noise reduction to one noisy room;
• raise a quiet guest without raising everyone;
• edit cross-talk by choosing which speaker stays in the final moment;
• build a cleaner podcast mix while keeping the live recording intact.

ISO tracks do not make a bad recording automatically good. You still need a useful microphone, a sensible guest setup, and a post-production editor. They preserve options that a mixed track removes.

Why Scale is the starting point

Capturing, synchronizing, and storing separate participant tracks requires more server storage and processing than saving one composed program. In the source plan structure, ISO tracks are reserved for Scale ($199/mo) and Enterprise deployments. Scale supports the multi-guest production workflow and includes Pro Audio by default; Enterprise uses a custom deployment.

The feature is most useful when the recording has value after the live event: a podcast with recurring guests, a panel that needs careful editing, or a production where one noisy connection should not ruin the whole episode. If you publish the live mix as-is, the extra tracks may not justify the plan.

Decide before you go live

1. List the guests and the post-production changes you expect to make.
2. Decide whether a single mixed track would leave you stuck when someone talks over another speaker.
3. Confirm that your Scale or Enterprise workflow includes the ISO option.
4. Run a short multi-guest test and check that each participant produces a separate track.
5. Keep the composite recording too; it remains the reference for how the live show sounded.

“Fix it in post” only works when you have the raw material to make the fix. For podcast producers, ISO tracks are that raw material—and the reason the Scale plan can be worth considering.
