PHON is a studio monitor controller in software: A/B your mix against Spotify or any app, level-matched, with ISO 226 loudness compensation tied to your calibrated level. No driver, no aggregate device.

AudioBridge routes audio between any tracks and any DAWs, latency-compensated. NNA Virtual Audio is a free virtual device, 1 to 256 channels, for everything else.
