This is really awesome and very informative. Really gives some insight into the basics of DSP processing and very well presented. Love it! Would be super awesome to see how this would compare to an 1176 or how to make it react like an 1176 vs. just a compressor with controls. Could give some real insight into the modeling and character of DSP processing.
Nicely done! Simple effective examples to explain how compression works. Also, I’m an excel kind of guy and love to see it being used for things other than boring work data MI. Cheers
Been wanting to watch this for a while and finally managed it! Great idea, and very good explanation of how compression works. I’m not sure I followed why you did the Log10 part, was it just to get a more usable number to work with than the raw data in column a? Could you have transformed the raw data in a different way? (I’m not a mathematician, in case that wasn’t already glaringly obvious)
Sound is logarithmic so -20 to -10 is the same as -2 to -1 or something like that. It's not a linear numbering system so to work on it in a linear fashion you have to do the log tranforms... I'm no mathematician either!
10db above the threshold attenuates to 5db above with a 2:1 ratio as it halves it. 4:1 halves it again. Inf:1 allows nothing above the threshold. What is wrong with that?
“The amount of gain reduction is determined by ratio: a ratio of 4:1 means that if input level is 4 dB over the threshold, the output signal level is reduced to 1 dB over the threshold. The gain and output level has been reduced by 3 dB. Another way of stating this is that any input signal level over the threshold will, in this case, be output at a level which is only 25% (i.e. 1 over 4) as much over the threshold as its input level was. The highest ratio of ∞ :1 is often known as limiting, and effectively denotes that any signal above the threshold is brought down to the threshold level once the attack time has expired.”
