The audio interface needs a feature called 'direct monitoring' or 'real time monitoring'. Those features are what made Teac Porta-Studios so popular for home studios.Ī computer component called an audio interface is needed to get audio into a computer for recording and out of the computer for listening. Not every tape recorder let you record one track at a time or had a switch that eliminated latency. You record a track, flip the switch that uses the same record head to playback the pre-recorded track while the same record head is used to record new audio on an empty track. Tape recorders get around this latency by adding a switch that temporarily makes one record head track a playback head. In an analog tape recorder (cassette or reel to reel) latency is the time it takes for the tape to travel from the playback head to the record head. There will be the processing time of the computer generating the audio and sending it to the headphones, your reaction time and the time for your singing to be processed and recorded. The only time you'll notice latency is when you're trying to blend audio from outside the computer with audio created inside the computer.įor example you connect a microphone to the computer and record your singing to computer music in your headphones. For most people latency of 9 milliseconds or less is tolerable. Audio latency is the time from when the command to play audio is given to the time the audio is heard.
