This comes down to a dynamic range of almost 96 dB. Which is exactly the dynamic range of 16 bit audio. Makes perfect sense to me. Maybe -96 dB to +3 dB would have been even better. But the risk of having an amplification factor is that the unsuspecting user could cause clipping and distortion. -----Original Message----- From: wdmaudiodev-bounce@xxxxxxxxxxxxx [mailto:wdmaudiodev-bounce@xxxxxxxxxxxxx]On Behalf Of Tim Roberts Sent: Thursday, April 21, 2011 5:37 PM To: wdmaudiodev@xxxxxxxxxxxxx Subject: [wdmaudiodev] Re: Setting KSPROPERTY_AUDIO_VOLUMELEVEL Mike Kemp wrote: > I don't understand the assertion that "-91dB to +3dB isn't real useful in > most *typical* PC environments". > > This is a totally reasonable range for an audio volume control. A power range of 1,000,000,000 to 1? Color me dubious. Most PC-quality equipment can't get anywhere near that. -- Tim Roberts, timr@xxxxxxxxx Providenza & Boekelheide, Inc. ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/ ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
