It's well-known that the signal processing of an SDR adds a significantly amount of latency, the SDR software on the computer adds more latency due to data buffering, FFT, decoding, demolutaion, audio buffering, etc, not to mention that most computer systems aren't a real time system and have unpredictable delays as well.
Software Defined Radio

Latency: "Latency refers to a short period of delay (usually measured in milliseconds) between when an audio signal enters and when it emerges from a system." (from Wikipedia ). This program uses WASAPI: "The Windows Audio Session API (WASAPI) is Microsoft's most modern method for talking with audio devices.

Also uncheck the filter audio box, chances are, your application will want a clean signal coming from SDR# to decode digital data properly. Decreasing latency If you are decoding time sensitive information (Trunked radio decoding), turn down your audio latency so it is low enough to where the audio doesn’t pop from buffer underruns, but is ...
Extremely Low-Latency, Bidirectional, Multichannel Audio ...

Software-Defined Radio Audio Design Example We had a customer that needed an extremely low-latency (submillisecond) link for both wired and wireless 10-channel bidirectional audio. For the wireless solution, we utilized our software-defined radio (SDR) audio expertise to develop a custom SDR with sub-ms latency using Analog Devices’ (ADI ...
Audio latency when used as a panadapter/sub receiver ...

The problem is the amount of audio latency through SDR Play and HDSDR. This is not a problem when it was only used as a visual panadapter but when listening to both sources, there is a noticeable amount of latency through SDRPlay and HDSDR. I haven't measured it, but it is long enough that it would be difficult trying to use this in a crowded ...
Audio latency and CW QSK - SDRplay Community Forum
https://www.sdrplay.com/community/viewtopic.php?t=2148
Audio latency and CW QSK. Post by W2DLC » Thu May 04, 2017 3:59 pm OK, I've narrowed the CW transmitter overload problem to the latency of the receiver. Basically the QSK T/R switch does it's job before the signal gets through the SDRPlay, so the SDRPlay doesn't get muted before the next key down. ... and they aren't available in SDR Console 2 ...

The carrier level control on the Transmit setup tab adjusts the ratio of carrier to audio. o The normal setting is 100.0. At this level, assuming sufficient mic gain, you will achieve 100% modulation. The ALC limits the audio such that you will not exceed 100% modulation.
