Garbled Transmit Audio


I sent the message below directly to Marcus. Wondering if others have experienced this too?


It seems the transmit audio starts out OK but the longer I transmit the transmit audio gets more garbled and distorted when listening to myself on another radio.  I’ve tried small and large buffer sizes along with various mic gain settings. I always keep the mic threshold at 0 since that always makes the transmit audio sound bad. Any Ideas?

And this was his reply to me:

Many thanks David,

I am currently working on a few changes regarding Audio and hope to address this as well.

Again, many thanks for letting me know.


Marcus, DL8MRE

    It’s was reported to me as well. My transmit audio was clipping. Though I was just running the mic gain too hot. All ok on Flex Windows SmartSDR

  • Per Marcus's suggestion I'm sharing an idea here,

    I just bought a Yeti X (Their newest mic) to use with the Smart SDR software on my Mac. BTW this works on the PC version too. What’s nice about only this Yeti mic is that it works with the Blue Voice software from Logitech and offers controls to tailor the way your voice sounds on transmit. The best part of this software is they offer an expander/gate and noise reduction feature to mimic the DEXP button that doesn’t work on the Smart SDR software when used on a computer. The DEXP button only works on a non-USB mic connected directly to the radio. For those not familiar with the DEXP, it silences that background roar on your transmitted voice when you're not speaking. So basically it's a gate when you stop speaking. Once again to be very clear The Blue Voce software that connects through the Logitech GHub only works on the latest Yeti, the Yeti X. If you buy any other Yeti the software won't work.

     See the screen shot. I highly recommend this mic.

    Check out the new update, v1.4.1, to see if it solves your sound issues. It is now available in the App Store.

  • I just did as I received an email from Marcus. It's fixed!!!!

    Thanks Marcus. I now sound the way a Flex should sound.
