A 64-track recorder is an audio recording device that is designed to capture and record multiple audio tracks simultaneously. This means that you can record up to 64 individual audio sources, such as individual instruments, microphones, or other audio inputs, at the same time.

Once the audio has been recorded, a 64-track recorder allows you to mix and edit the individual tracks together to create a final audio product. This can involve adjusting levels, panning, EQ, and other parameters to create a balanced and cohesive mix.

64-track recorders are commonly used in professional audio production settings, such as recording studios, live sound reinforcement, and film and television sound design. They allow engineers and producers to capture a wide range of audio sources simultaneously, which can be particularly useful in situations where multiple instruments or voices need to be recorded separately for later mixing.

In addition, a 64-track recorder can also be used for overdubbing, which is the process of adding additional layers of audio to an existing recording. This can be useful for adding harmonies, percussion, or other elements to an existing track to enhance the overall sound.
