    Hi, I tried googling this, but every answer I'm reading is over my head. Buffer Size is something people advise changing. But for reference, I don't know what a buffer is nor do I know how to find my buffer settings. Someone else said to watch your CPU/HD meter, and I again don't know what those are, nor how to change them. Any help would be great, feel free to assume I don't know anything about the technical sides of recording.

    First you need to eliminate if it's the computer or the monitors. So try to use other speakers or headphones.
    If it's not the computer, I read that some monitors could need some break in.. Run a signal at medium level for a while and see if the cracking stops..

    @redcat Buffer settings certainly can cause crackles and pops when the audio circuit is under pressure to produce. It’s dependent on your interface type and quality as to how high to set it. In Logic Pro X all audio related settings are in audio, take you a quick look at the audio tab and you’ll see it as a number usually it defaults to 128 or 256, been a while since mine was default. Gnerally speaking unless you have a huge project, you’ll not need higher and your results audio wise will be as expected.

    It is virtually impossible to offer help with so little (none) information.

    Computer used? Operating system? Interface manufacturer and model?

    As a test, unplug one of the cables going into a speaker and connect the cable to a line input on your interface. Then record 30 seconds or so on that input channel while playing back a sample where you can hear crackling in the remaining speaker. Put an MP3 copy of that recording on this site using the "Upload a file" button at the bottom right in the reply box. When we get to have a look at it, we should be able to tell you whether it's a buffer problem or something else.

    My apologies. I did not read the thread title carefully (pre-coffee) before responding...

    I hope some of the other replies help solve your issue.

    Buffering is storing up data in a temporary memory before sending it to the next stage, so there's always data ready and the next stage never has to wait for it. It's a reservoir.
