Overview<\/h2>\r\nSometimes you need to measure latency and you also want to use Ableton Live. This “TH Latency Measurement<\/em>” Max for Live patch allow you to measure the latency between 2 channels. Send audio out one channel, receive that audio into\u00a0another, then run it through the M4L patch to view the\u00a0delay in milliseconds and samples.\r\n\r\n\"M4L_Latency0\"\r\n

Detail<\/h2>\r\nPlace “TH Latency Measurement”\u00a0\u00a0on a Return track to measure the delay between the Left and Right Channels. Setup an Ableton Live session to output\u00a0audio (preferably simple, such as a sine wave) out the left channel while also routing the audio to the return track. Receive audio from a channel, pan it right and send that to the return track.\r\n

Example #1<\/h2>\r\n(One Computer<\/strong> – Live and Jack)\r\n\r\nFollows is an example of audio routed out of Ableton through Jack (with a “Frames\/Period”, i.e. buffer of 1024 samples). Stereo audio is routed out of Live and back into Live. The audio is also routed to the System so that we can hear it.\r\n\"M4L_Latency1\"\r\n

Example #2<\/h2>\r\n(Two Computers<\/strong> – Live #1-> Jack -> Jacktrip -> Jack -> Jacktrip -> Live #1)\r\n\r\nIn this example audio is output from Live on Computer #1, sent to another Computer #2\u00a0via Jacktrip, then routed directly back via Jacktrip, back into Live and into the Return track for measurement.\r\n\r\nComputer #1<\/strong>\r\n\r\n\"M4L_Latency4\"\r\n\r\nComputer #2<\/strong>\r\n\r\n\"M4L_Latency3\"\r\n

Example #3<\/h2>\r\n(Two Computers<\/strong> – Live #1->Jack -> Jacktrip -> Live #2 -> Jack -> Jacktrip -> Jack -> Live #1)\r\n\r\nComputer #1<\/strong> (same as the above example)\r\n\r\n\"M4L_Latency2\"\r\n\r\nComputer #2<\/strong> (Ableton Live routes audio in and directly out)\r\n\r\n\"M4L_Latency5\"\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
