Re: Volume Control Function - Just dBFS?

I am using WASAPI in exclusive mode. The Roland ADC output level in dBFS and the Audacity data stream input level in dBFS match precisely when the 'volume control' is set at 100%. This is what I expect to see if Windows has no control over the bit depth of the data stream. To my way of thinking, nei...

Re: Volume Control Function - Just dBFS?

Changing the 'gain' of a digital audio datastream is actually changing the resolution of the digitized waveform (i.e., bit depth). Is this done in Audacity before or after the conversion to 32 bit float? If before, it would be unwise for anyone to record at 16 bit depth with the Audacity volume cont...

Re: Volume Control Function - Just dBFS?

My concern is that I am already controlling the dBFS output of the Roland ADC, so I thought that the Audacity volume control would (should) have no effect on the incoming data stream via USB and be grayed out since it makes no sense to have a redundant control. I do leave it at 100%. My preamp outpu...

Volume Control Function - Just dBFS?

I am running a Roland Quad Capture ADC to USB into Audacity for recording. My mic volumes are preset to about max -3dBu up-line from a tube preamp. The Quad Capture preamps are set at minimum (unity gain). The Audacity volume control is not grayed out and is adjustable (I leave it at 100%). I don't ...
