    As I'm sure most of you know, jrthebassguy has decided that he needs to spend some more time with his life instead of TalkBass (shame on him! :) ). His farewell thread is located here.

    And so it is my honor to introduce the new Effects moderator - you all know and love him... let's hear it for Bigfeet! :D

    Welcome BigFeet. Your omniring and manual should come in the mail shortly. First, of course, is the ritual body shaving.

    We're thinking Kenny Rogers or Robin Williams.

    More importantly, what's the difference between overdrive and distortion? And wut's a compressor do, REALLY?
     
  8. Thankyou all, the age of overdrive and compression is now over sadly, but it had a good run. Welcome to the age of envelope filters! j/k
    I'll try not to let you down and do my job as a moderator the best I can.

    OH BTW, A compressor is basically a variable gain device, where the amount of gain used depends on the level of the input. In this case, the gain will be reduced when the signal level is high which makes louder passages softer, reducing the dynamic range. A compressor's input/output relationship is often described by a simple graph. The horizontal axis corresponds to the input signal level, and the vertical axis is the output level (both measured in decibels). A line at 45 degrees corresponds to a gain of one - any input level is mapped to exactly the same output level. The compressor changes the slope (makes it more horizontal) of that line above some value called the threshold (which is most often adjustable). The height of the line defines the dynamic range of the output, and the slope of that line is the same as the compressor's gain. The compressor weakens the input signal only when it is above the threshold value. Above that threshold, a change in the input level produces a smaller change in the output level. The compressor setting is usually stated as a ratio, such as 2:1, which means that the input level would have to increase by two decibels to create a one decibel increase in the output. With a 4:1 setting, the input would need to change by 4 dB for a 1 dB change in the output level, and so on. Limiting is simply an extreme form of compression where the input/output relationship become very flat (10:1 or higher). This places a hard limit on the signal level. the compressor makes loud signals quieter, but it does not make quiet sounds louder (although it may be perceived that way). However most compressors do have a secondary gain stage for adjusting the output level so that if you turn the compressor on while playing, the extra gain will prevent your instrument's volume level from dropping. You can make a case that this extra gain stage is or isn't really part of a compressor, but in any case, that is what makes the softer sounds louder. Now discussing exactly how the level detector in the compressor operates. It is usually some sort of time average of the input (often a root-mean-square (RMS) calculation). Alternatively, the instantaneous peak voltage or sample value can be used, in which case, the compressor becomes a hard limiter.

    When the level sensing function is a short time average, the compressor will take a little time before the gain is adjusted to meet the new input level. The amount of time the compressor takes to respond when the input level rises above the threshold is called the attack time, and is usually fairly short (under 100 ms.). When the input level is above the threshold and then drops below it, the compressor will take some time to increase the gain as well. This is the release time of the compressor, which is generally larger than the attack time (possibly up to a second or two). The effects of a compressor on a signal. Only the middle portion of the input is above the compressor's threshold. Note the overshoot when the signal level increases (it takes some time for the gain to decrease), and the attenuation when the input signal returns to the first level (and the gain increases). The release time is generally longer than the attack time.
     
  9. Overdrive and Distortion:

    Overdrive is when your driving on a highway or just plain going fast and when you go really really fast your governer will kick in and take over, then your in overdrive. j/k

    Otherwise known as clipping, distortion cuts off the extreme highs and lows. In other words, it eliminates the highest highs and lowest lows, therefore creating a distortion effect. Distortion is used a lot by grunge and metal players. Overdrive unlike distortion, overdrive is just a gain setting that is set higher than the chip can handle, therefore creating a slightly distorted sound. Sometimes a clean channel on your amp will become overdriven when you crank it all the way up.
     
  10. Have fun in modland Bigfeet, I'm sure you will do a great job!

    I thought compressors were pumps that pressurize air........:p
    Just kidding, good explanation of compressor function. Now if everyone would read that I wouldn't need to go into extended rants every couple of weeks.

    Now explain downward expansion! :D
     
  11. B... Bu... But, I don't know that much about human stereo types!

    :rolleyes: :p

    Welcome to the gig. It's a GAS....get it? HAHAH...oh, wait, no one's laughing..:(

    :D
     
  13. Welcome, my bigfooted friend.

    You know what they say about men with big feet?

















    Big shoes!

  15. they break their stomp boxes...?
     
  16. it's about time! if i was ever certain about one thing, it's that you'd be the moderator of Effects. welcome aboard.
