Podkstr vs Async (formerly Podcastle)
Two close feature lists. The difference lies in how deep each feature goes.


The closest competitor
Async is the tool closest to Podkstr. Its features, its strengths and its plans are listed in the table below, with the date they were checked.
The two tools have nearly the same feature list. They differ in how deep each feature goes.
Controls or a workshop
In Podkstr, each track takes up to eleven effects, each with its own visual editor: the curve, the threshold and the gain reduction move in real time. A master bus processes the whole mix.
A control corrects a sound. Eleven effects per track make it possible to work it.
Two differences in the sound
Raw capture: Podkstr deliberately switches off the browser's gain control and noise suppression, because that processing cannot be undone once recorded.
Measured loudness: the output is normalised to -16 LUFS, the level Apple Podcasts recommends, and measured.
Price
The Async plans are listed in the table below, as displayed on the date they were checked.
Who each is for
Async for anyone who makes as much video as audio and is happy with automatic cleanup.
Podkstr for keeping hands on the sound, with published prices.
