Why would you want to do that? Do you have such a thing and want to use it for another usage? Anyway there are many different types of meter rectifiers, some may be suitable, some less so.JAY X said:is it possible to use a peak detector vumeter rectifier as a compressor sidechain? with some mods perhaps... ;D
What do you mean, inverting. The input signal is rectified, so the absolute value is measured, then logarithmically converted.JAY X said:I 'm trying now with a 4305 rms detector.
From the datasheet, it is not clear if the RMS input, is an inverting input.
If it is, i could control 2 vca with it.You can control several VCA with one RMS detector, but most of the times, an opamp is used to provide scaling and threshold.
I don't really understand what you think you want to do, but remember that summing logarithms results in multiplication.If it is not inverting, maybe i could use the inverting input of the vca inside this chip to sum the input signal from other two vca's...
That is cruelly necessary.I will post a schematic, to make it clear. ???
This is 404 to me.JAY X said:A picture of the sidechain
OK, it works. You must be aware that the sum of L+R may be smaller than expected, due to possible phase cancellation, resulting in less compression than expected. Depending on your application it may be an issue or not.JAY X said:ok, a new picture...
It's not mandatory; if the gain was different than unity, it would just change the threshold, which can be adjusted elsewhere.JAY X said:Another question, is if the vca in the sidechain should be at unity gain, i suppose..
Yes.And Ec- should be tied...to gnd?
