It's fantastic MB compression, equalizing, clipping and limiting tools are awesome for our hobby. They maximize average talk power, improve intelligibility, punch and audio quality. Here are my profiles on date December 31, 2014, the type is in the filename. https://www.dropbox.com/s/7kjvjaaq589fu ... 0.sts?dl=0 https://www.dropbox.com/s/wy17eveh8dreu ... 0.sts?dl=0 https://www.dropbox.com/s/ctb824cuqd9bn ... 0.sts?dl=0 I also have a 5 k profile for ESSB-like playing. Keep in mind that these profiles include my hardware setups, so do only load audio profile when testing. Feel free to apply, comment and share your own discoveries. Many thanks to Hans for this outstanding software. Happy New Year to Everybody 73 Peter HB9UQX win 8.1 - i7-2k6 16 GB RAM 120 GB SSD - RME fireface UC - Neumann TLM 103 - ANAN 100D - Sennheiser HD650

I am running my mic into an Asus X7 sound card and the output from the card into the mic jack of the radio. Monitoring the audio from the sound card I get a low level echo. Is this normal?

You might try using a VAC connection from Stereo Tool to PowerSDR. VB-Audio has a few nice free ones for download. I'm still experimenting with ASIO audio interfaces and will post my results with the PreSonus AudioBox 22VSL which I just hooked up. I always had an echo with my Focusrite Scarlett 2i2 unless I used a VAC Barry N1EU

If you hear an echo, are you sure that you're not passing the input to the output in the sound card settings? Because then you would hear both Stereo Tool's output and the original input.

Alternatively, it could be that your microphone is picking up the sound from - for example - your headphone if you play processed audio through that.

Nothing inside Stereo Tool can cause echo's, so if you hear any there's some other signal present that shouldn't be there.

FWIW, I wouldn't feed the soundcard output to the front mic in, but on the rear connector line in level.
