    Hey man! Absolutely love this tutorial series! Curious on your thoughts (and anyone else’s if they have an idea!) as to what might be going on with my system. After refreshing with this tutorial series a bit, I was playing around with the I/O buffer size in particular to get a better empirical understanding of how it effected everything. Since then, there has been latency when recording (or even with the track in Input or Record enabled and checking lines/levels/etc) with any buffer size – even the lowest ones. It’s definitely worse the higher I go and admittedly, I am using an older Mac with Logic Pro 9 but, it’s aggravating as it’s worked perfectly up until recently. I haven’t been able to properly record anything aside from internal instruments within Logic.

    Halp!!

    only thing: the intro is a bit long

    if I Record with 96 kHz and 24 Bit with my Steinberg UR28M, how can i export the File with 44,1 kHz for CD audio for example? ??

    The two main factors that affect the quality of the files we record are sample rate and bit depth.

    Set Before you record

    File —> Project Settings –> Audio.

    SAMPLE RATE
    ===========================================
    The signal coming from a mic is just an electrical voltage.
    The audio interface takes that signal and samples it in intervals to convert it into Digital
    Takes that voltage and converts it to digital by sampling it at different intervals per second.
    The sample rate controls the amount of samples taken per second during the analog to digital conversion process

    WHAT SAMPLE RATE TO SET
    ——————————————————————
    For recording
    Quick Answer: 48000

    *Take your sample rate divide it in half and that will you the highest frequency you can accurately reproduce.

    44100/2 = 22050 Hz
    48000/2 = 24000 Hz

    So whats the point of using a higher sample rate? (48,88 or 96)
    You will get more accuracy. So your mids and highs will be crisper.

    However, the bigger the sample rate the bigger the file size.

    What Happens if you record a signal that is above the Highest Frequency your microphone can capture?

    When the frequencies you are trying to capture are higher than your Nyquist since the frequency cannot be captured at that sample rate the signal you capture folds over in a disharmonic way.

    ——————————————————————————————————————————————

    BIT RATE:
    =================================
    Bit Depth
    Number of bits of information taken PER SAMPLE during the analog to digital conversion proccess.

    Logic supports 24 bit and 16 bit recording.

    Prefrences —> Audio —> 24 bits

    If you recorded at 44.1 each of those 44.1 samples per second will hold a 16 or 24 bit binary word (word is a type of size, a number of ones and zeros)

    So Bit Rate sets the size of each segment of the signal that is being sampled during the analog to digital conversion proccess.

    Bit Depth : Higher Bit Depth
    Bit depth controls the dynamic range between your line level and your noise floor.

    Noise floor = quiet Noise at the very bottom level of recording

    Having a lower noise floor means you can compress more without exaggerating the noise

    You are the bomb dude!!!

    My project audio settings show only sample rate and pan law options, how do I change this?

    Great tutorial . How is it work for exporting doh ? if I record my guitar at 88.2 rate when I export the song logic tells me only up to 48khz is supported so it change my file to 48.im confused

    I cant find the bit depth setting in the Audio/devices tab. did it move?

    @musictechhelpguy
    I have two major problems that keep bothering me in Logic Pro x , everytime I record notes , the sequencer has a thing for cutting off my first note or the note is out of the loop and I have to quantize it ( I don’t like to quantize that much because it takes the feel away from the music ) and another thing is when I set my buffer size to 128 and lower it crackles very bad whenever I use more than one software instrument or plugin , im running Logic Pro x on a MacBook Air early 2015 model with 128 gb
