If you record audio in an untreated room (or your remote guest does), often you’ll get excessive echo/reverberation, as sound waves reflect and return to their starting point. This is true whether you record audio only or audio with video. In my case, I find that I have a much more severe echo issue with some of my remote guests’ audio than my own. That’s especially true with those who have have more reflective environments and —in some cases— use standard phone earbuds when interviewed. This article will explore one software solution to solve this: the CrumplePop EchoRemover plugin, in

and how it can be applied to a multitrack editing session with a DAW (digital audio workstation) like Hindenburg Journalist Pro. The CrumplePop EchoRemover plugin works with many other macOS apps too. Details and recordings are ahead.


Compatible software editors

The CrumplePop EchoRemover plugin officially works in the following macOS editors, including a dangerous one, as indicated below.

  • Apple’s Final Cut Pro
  • Apple’s Logic Pro
  • Apple’s dangerous GarageBand (kryptonite for video, since GarageBand sadly doesn’t support our 48 kHz standard. See Enter the 48 kHz Alliance and 48 reasons why Garageband is kryptonite for video production, illustrated above.)
  • Adobe Audition
  • Adobe Premiere Pro
  • Blackmagic’s DaVinci Resolve
  • Hindenburg Journalist Pro (tested by me)The CrumplePop EchoRemover plugin will likely also work with other programs for macOS that accept AU plugins. I did my testing with Hindenburg Journalist Pro, which I have covered in many other articles in ProVideo Coalition, since it’s my favorite multitrack editor for audio storytellers for conventional computers.

Using the CrumplePop EchoRemover plugin

As shown above,, you select CrumplePop EchoRemover among other plugins by clicking on the Effects button on the desired track, clicking on one of the buttons that are currently Off, and then clicking on CrumplePop followed by EchoRemover AU.


Then you click on Remove Echo and the green marker indicates that it’s active. Then you begin adjusting the three settings using your favorite headphones or reference monitors.

I first used CrumplePop EchoRemover when editing the interview I had done with Spaniard music producer Jesús Yanes. This conversation was on CapicúaFM episode 41). I interviewed Jesús remotely using Cleanfeed (covered in several articles) from Madrid, Spain. Evidently he had connected his studio microphone in his office for this remote interview, not in his music studio, so we had a very high amount of reverb/echo. As a result, I needed to set the Strength very high for his track, at 70.8, as indicated in the screenshot above. The other two settings (Release and Bass Reduction) are done after Strength). In my experience so far, no Base Reduction has been required or helpful, but this will likely change depending upon circumstances.


I used my favorite unbranded yet brandable isolating headphones to make the adjustments, which was very easy and fast. See Review: Status Audio CB-1 brandable isolating headphones, illustrated above (Amazon link).

Both audio files below are compressed WAV 48 kHz. Please use WiFi or unmetered mobile data, and use headphones or reference monitors to notice the differences as best as possible:

Thanks to the power of multitrack recording and editing, we can treat each sound source separately. Jesús Yanes’s track needed heavy echo treatment (70.8 Strength) and some compression too (I used Hindenburg Journalist Pro’s own Compressor, which is outside of the scope of this article).

On the other hand, since my voice had compression applied during the recording,

thanks to the Aphex compressor built into the multifaceted RØDECaster Pro shown above (B&H link) mixer/recorder (which I have covered in several articles), my track needed zero compression and a much lower strength setting for EchoRemover: 33 as opposed to 70.8.

Conclusions and more information

I am delighted how effective the CrumplePop EchoRemover plugin is, how simple it is to use, and that it works with my favorite multitrack audio editor for audio storytellers, Hindenburg Journalist Pro, in addition to all other popular audio and video editors.
