Description

Latency Meter is a simple M4L Live Set for measuring the latency of external audio or midi plugin devices and audio interfaces. To use it, download the LatencyMeter Live Project from the download link, the combination of several devices is the actual meter software - MeterAudio.amxd here is only one of several devices.

For audio plugin latency measurement, replace the M4L example device chain in the Audio Test Route track, for MIDI plugin latency measurement, do the same with the Midi Test Route track.

For audio interface latency measurement, select one of its channels in the Audio Out and Audio In tracks and directly connect them with a cable. For stereo channels, one cable suffices.

Hit play to start the measurement. The M4L devices in the Audio Meter, Midi Meter, Audio Interface Meter tracks respectively display the measured latency in ms.

MIDI plugin latency is measured with two distinct notes, therefore make sure that the same notes are passed by a measured plugin. Audio plugin latency is measured with a click and the left/right difference, therefore it must not distort or even delay the input.
