<div dir="ltr">I've noticed the same thing; it's yet another reason I prefer to trigger the voice memory in the radio (via Win-Test LUA scripts) rather than using a sound card as a voice keyer, though for SO2R, you must use sound card keying for automatic interleaved messages between radios. So, neither solution is perfect.<div class="gmail_extra"><br></div><div class="gmail_extra">I think Win-Test is recording the sound of pressing the "Esc" key, or the sound of clicking the mouse, which you must do to stop recording, but it could be something else. I'm also seeing a very loud spike at the <i>beginning</i> of every recording.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Editing the generated .WAV files with Audacity may be the only option for now. I agree it would be nice if Win-Test could automatically truncate the first and last 100 ms of the recording to eliminate these spikes.</div><div class="gmail_extra"><br></div><div class="gmail_extra">Another option worth investigating is VE3NEA's "Voice Shaper":</div><div class="gmail_extra"><br></div><div class="gmail_extra"><a href="http://dxatlas.com/VShaper/">http://dxatlas.com/VShaper/</a><br></div><div class="gmail_extra"><br></div><div class="gmail_extra">But I haven't tried it myself.</div><div class="gmail_extra"><br></div><div class="gmail_extra">73,</div><div class="gmail_extra"><div><div data-smartmail="gmail_signature"><div>Bob, N6TV</div></div></div>
