Monitoring your SIDETONE from your MIC or LINE INPUT in Near Zero Low Latency delay using JACKROUTER

[Chuck aa0hw]

test results are shown(no sound on video) for hitting a lever that sends a TONE into the mic input jack of a laptop...a separate USB RECORDING MIC is placed at an equal distance from from both the LEVER and the SPEAKER (ABOUT 6 inches to mic from both the lever and the speaker) the MIC measures the TAP sound when hitting the LEVER and the final output from the speakers of the TONE....there will always be some delay...however, you can lower this significantly using a LOW LATENCY AUDIO engine like the JACK AUDIO CONNECTION KIT/ JACKROUTER http://jackaudio.org/ JACK has versions for WINDOWS, MAC, LINUX and RASPERRY PI/arm
