Because Pro Tools Free uses the host processor in your computer for audio processing, playback, and recording there is a small amount of audio delay, or latency, when monitoring audio through the system. This causes a delay between the source audio and the audio going through the computer as it is input, processed, and output.To avoid hearing the delay in audio when you are recording you can monitor the audio that you are recording through a mixer (such as a Mackie 1202) before it enters Pro Tools Free. Here's how:-Route the audio that you are recording into your mixer. Next, route that signal back out of the mixer (preferably via an Auxiliary Send or Direct Out to avoid a feedback loop) into the audio inputs on your computer.-Route the main mix of Pro Tools Free from your computer audio outputs to your mixer.-Create the audio tracks in Pro Tools Free that you are going to record on.-Record enable the tracks you are going to record on. You should see levels on these tracks and hear the latency (delay) that you are trying to avoid.-Mute the tracks that you are going to record on. This will allow you to monitor the recorded audio through your mixer but not through your computer and avoid any monitoring latency.
