Reverse the track , apply SC4 , then reverse it back : now you have lookahead compression ( I think :? ) If you want lookahead, probably better to use a compressor that has lookahead :) Personally I find using a compressor well without real time adjustments is difficult enough without Preview playi...

I have a USB headset. A USB headset will not work with a mixer. USB headsets need to be plugged directly into a USB port (socket) on your computer. USB headsets are not designed to be used in multiples, just one headset connected to the computer. I am looking to record gameplay with some mates Plea...

It just means, you're right, envelope tracking and gain adjustment are the two (different) parts of dynamic compressors

Or do you think that ASIO Support was removed in Audacity 2.0.5? No versions of Audacity have ever been released with ASIO support. Although it is possible to add ASIO support to Audacity by building Audacity from the source code, this requires using Steinberg's ASIO SDK. Unfortunately there is a l...

"White noise" is loosely defined as sound that contains all frequencies within the audio range in equal amounts (constant power spectral density). So, by definition, if you narrow the frequency bandwidth it ceases to be "white noise". To take the narrow bandwidth to the extreme y...

I understand the envelope fitting and the gain curve parts to be different things. Yes, quite so. A common design for a simple hardware compressor, the envelope follower is a rectifier feeding a capacitor. The voltage across the capacitor increases as the peak signal level increases. When the input...

Nah, a novice will be just as confused by that. I quite agree, and was not intending to suggest that it could replace the current content in our manual. I was only responding to Paul L's query about the difference between upward and downward compression. A "gain graph" (input level / outp...

An interesting article :) particularly as the opinions stated come from such a credible source as John Murphy (former chief engineer for Carvin Corporation ). I particularly liked the (informative) quotation: "In response to a strong transient, these amps exhibit what looks like 'dancing harmon...

Is that really the conventional meaning of "upward" in anybody's experience? I think Wikipedia is incorrect in this case. I've never seen a compressor (hardware or software) that does anything like what is suggested by that graph, though that graph does seem to match their word descriptio...

Whether that is a "limitation" depends on whether you want that behaviour or not
Some good effects can be achieved by using the SC4 followed by a limiter (which is a common configuration when using hardware devices).
