Octave RTA

Octave RTA serves the practical side of audio work: it gives you a real-time analyzer for looking at frequencies while sound is playing. By our assessment, that makes it useful for musicians, engineers, and anyone tuning speakers or checking how a room behaves, because it turns sound into a readable graph instead of a guess. The trade-off is that it asks for some knowledge; if frequency plots and octave bands mean nothing to the user, the screen becomes decoration. In practice it is a measurement tool, not a listening app, so it is opened for checking and then put away again. It sits firmly in the technical corner of music apps, closer to analysis gear than to creative playback, and the Music category only captures part of what it does. The name is blunt in the best way: octave-based real-time analysis is exactly the job. It is strongest when the goal is diagnosis, and it stops being helpful when the user wants something musical rather than something measured.
