That's clipping, surely?

Yes, same thing because the transformer/valve/transistor/tape cannot supply any more signal.

Dave.

If we think how this would be done in DSP ... We need a non-linear function. Inverse tan would do it : https://i.ibb.co/T0mscND/arctan-x-graph.png The saturation is that at a certain point increasing the input doesn't increase the output. That looks very like a flux v magnetizing force curve. Dave.

I'm with Wonks, I've always thought of it as 'tape saturation'. Probably because, until your post above, I've never understood what transformer saturation actually was. Few do. "They" don't even really mean "saturation" on tape, really somewhere around 4-6% THD I would guess. Mo...

Yes Drew, my point. In the recording world "saturation" has COME to mean a mild form of distortion when in fact, electronically it is the most extreme form of distortion you can get.

But, like "rms" bloody watts I suppose I shall just have to live with the term!

Dave.

Yes, as Wonks says be careful. A valve amp fading down and up is almost always a problem in the heater supply.
MIGHT be the valve but I doubt it.

Dave.

I don't know what "saturation" has come to mean to recording folk but to any electronics engineer a saturated transformer is one that has ceased to BE a transformer and presents a resistive load to the circuitry. It is actually very, very hard to saturate a transformer. One instance for ma...

String rot is however a 'problem' of the lazy 21st century! Before the discovery of stainless steel and Aluminium you had to TAKE CARE of steel objects! Being as stainless steel was invented in 1913 I think the 20th century can take a bit of blame here too. ;) Well yes but Harry Brearley found the ...

When i was playing guitar and bass I never had a problem with string corrosion. I did however have a problem with wristwatch straps (remember them?) The leather would rot and fall apart in under 6 months. String rot is however a 'problem' of the lazy 21st century! Before the discovery of stainless s...

Doveman..mate! If you are now considering the SSL2+ and some fancy external hookup I urge you to look again at the MOTU M4. Unlike the SSL2 it has two extra balanced line inputs. Thus you could simply split the headphone output* (or buy a Behrry HA400, always handy and cheap as..) Run that to the ex...

You can use multiple audio sources in Windows (W7 anyway) I did it some years ago but you have to use mme drivers and the tracks are not sync'ed. They don't even start recording together, quite. I was using Samplitude SE8 and that makes it very easy to slide tracks to sample accuracy. They don't of ...

Pleased to report success using 2 x 10m active USB cables from the Mac in the basement connected to a powered USB hub in my back room. I'm able to attach the Focusrite plus keyboard/mouse and various midi units without a problem. Just waiting for the HDMI boxes which I'll run usuing shielded Cat6. ...
