Takes and the history
How AI Audio keeps every run and take with its settings, plays them on waveforms, makes variations and downloads WAV or MP3.
A run makes one to four takes, which appear one by one. A run is queued, running, done or failed. Play a take on its waveform, rename it, download it, make variations (same settings, new seeds) or reuse a run's settings.
A failed run is refunded the takes it never made. A run you queued by AI is made when somebody has AI Audio open.
