These three tools cover most everyday audio needs that don't require a full studio setup. Voice Recorder is the simplest option when you just need a quick clip. Online Dictaphone adds live speech-to-text on top of that, styled after the cassette recorders that inspired it.
Tone Generator goes the other direction — producing sound rather than capturing it — for testing speakers, calibrating equipment, or a quick informal hearing check. Between the three, most one-off audio tasks that would otherwise need a separate app are covered.
