Show HN: Hear Yourself – Free low-latency audio monitor for macOS

LineIn by Rogue Amoeba was discontinued in 2017. The alternatives (Audio Hijack, SoundSource) cost $50-120 for a simple passthrough feature.

  Built a free menu bar app that does one thing: routes your mic to your speakers with ~1.3ms latency.
