My goal is to review and selectively remove speech, especially known adverts/commercials, from numerous recordings of a community music radio station (that I work for).
Are there any DAW plugins (eg VST) or apps or projects that could assist with this? Preferably (but not necessarily) macOS or macOS-buildable.
For example, a DAW plug-in to generate an "indicator track" alongside a subject track, or to insert marker spikes or tones (eg to a copy of that track).
Alternatively, are there any stand-alone options?
(I initially asked at superuser, where I was advised to instead post here).
