    Love it!

  2. sguitar says:

    can u give me the order of things u want me to talk about?? 1. pre-amp etc

  3. isteve says:

    think you should start with how analog signal from mics and guitars are different levels. how the interface uses the pre amps to adjust the level making low levels stronger and high levels weaker. then the analog signal gets converted to digital (electrical pulses to 10010100101) how the digital signal now contains a digital description of the sound along with time. Then it goes to the Firewire or usb to the computer.

    the same thing happens in reverse when it is played back.

    And it was nice seeing you friday fun little jam with Mr. M.

    k i put that into the notes im going to read off. is anything thats should come next?? thanks

  5. isteve says:

    not sure but you may want to add what the interface does. like how it lets you record a track and play it back while recording another track and how depending on the interface it allows you to record multiple mics and instruments at the same time and each input can have it’s own track for separate editing.

    ok ive got that down. i know what i should talk about just not in what order. is there a certain order??? lol so far i have what the interface does and how it works. thanks

  7. isteve says:

    your the smart one but i would start with what what a interface is and that it replaces the soundcard.

    then what it does. (allows multi channel audio inputs to be recorded) and why it’s important

    next follow the signal path

    comes in to the interface as analog

    pre amps (adjust signal levels)

    converter (turns analog to digital)

    Firewire/usb sends to computer

    did you get my email with the links to some vid i ripped


    you can see them here there is 3 of them

    so i have the “journey” it takes to the computer. but its not ten minutes, i need to add in some more like stuff just not sure what. i have a couple minutes worth of speaking. so far i have watched the dynamic range, i got it but idk how to explain that and weave it into it. haha oral reports are fun.

  9. sguitar says:

    i also researched about drivers. this is what i put in the report.

    The driver is the critical code that manages the traffic of data going from the cpu to and from the DAC. It organizes the data so the CPU can fetch it when the audio application says it is needed. There are certain rules the driver has to follow that are set by the operating system. The application and the CPU have to follow the rules, and if the driver interprets the rules properly, all will work.

  10. isteve says:

    the driver (in case of a mac it uses Core Audio driver) is just a list of instructions that can translate the interfaces language to the CPU language and back and makes sure all the components talk to each other.

    Maybe you can add in the DAW Digital Audio Workstation (garageband in this case) and what it does.
    That can be a time filler, if you can have garageband setup and do some recording could be useful in explaining why you need a interface.

    10 minutes is a long time to talk about anything. I’m sure you’re not the only one trying to fill up a whole 10.

  11. sguitar says:

    yeah, he said i could demonstrate i just have to explain things, so i’ll be explaining how they work twice, but im not sure anyone will know cause its a confusing subject.

  12. sguitar says:

    one more thing haha. so how should i transition from atod into the daw???

    • isteve says:

      Maybe start with opening statement saying how your project is about how music recorded to a computer. then a quick overview of the components guitar/mic the audio interface computer/DAW showing each. then when you’re done with the part when the digital signal gets to the computer you can talk about the DAW software.

  13. isteve says:

    trying to explain anything is hard, trying to explain something to people that don’t care is almost impossible. now you know how your teachers feel everyday 🙂

  14. sguitar says:

    so how should i explain what clipping is?

  15. sguitar says:

    i timed myself i have about 4 minutes. but i am going to break down the steps more and that will ad time. lol i can also pause a lot.

  16. isteve says:


    not sure how to explain it but maybe you could a example of when some yells into a microphone and you get that terrible loud and fuzzy distorted sound.

    do you have any free time sunday to do some jammin?

  17. sguitar says:

    possibly, haha i’ll get back to you tonight
