And they sound fine. As does William, etc. if you've paid the license fee to cepstral. </div><div id="AppleMailSignature"><br></div><div id="AppleMailSignature">So, what are you looking for? Loudness or clarity? Loudness you can fix with Audacity; clarity (or fidelity) can't be created in an 8kc sample rate unless it was there to begin with; IOW you can't put in what wasn't there from the start, and current PC-grade mics are not the way to go, neither is starting from mp3 files or other lossy codecs.</div><div id="AppleMailSignature"><br></div><div id="AppleMailSignature">Maybe I'm lucky in that I have a recording studio and pro audio equipment at my disposal, as well as contacts with pro radio and TV voice artists...but I've heard great amateur announcements done with simple mixers and a decent Heil or Electro Voice mic, recorded into a wav file, edited, then downsampled to work in Allstar as per the directions in the archive.</div><div id="AppleMailSignature"><br></div><div id="AppleMailSignature">But, the beginning HAS to start with the best quality and go down from there, not start with low quality and try and go up. </div><div id="AppleMailSignature"><br>--<div>Bryan</div><div>Sent from my iPhone 6S.<span style="font-size: 13pt;">..No electrons were harmed in the sending of this message.</span></div><div><br><div><br></div></div></div><div><br>On Jan 18, 2016, at 10:16, Robert Newberry <<a href="mailto:N1XBM@amsat.org">N1XBM@amsat.org</a>> wrote:<br><br></div><blockquote type="cite"><div><p dir="ltr">I followed the directions on ohnosec for using audacity for recording audio files. I use them as tail messages and that works fine. The audio quality however is eh so-so and I feel it could be better. I know one thing the normalize feature called for -6 and I ended up bumping it to 0 db just so it could be more audible.</p>
<p dir="ltr">Is there anyone willing to share their experiences? It seems from listening to traffic on allstar the quality of messages could be better.</p>
