If you have ever spent hours on end preparing audio files for a mix, StereoMonoizer is about to become your new best friend. For the first time ever, you can automatically analyze audio files, determine their stereo content, and convert to the correct format, before you import into your DAW. That way, you can get a lot more out of your mix system. Drastically cut your CPU usage, use fewer voices, take up less space on your hard drive, and have better session organization. StereoMonoizer makes all of this possible, and more.


  • Find mono sounds in stereo files, and convert to mono

  • Innovative waveform display, showing stereo content overlaid on audio waveform.

  • Applications for mixers, producers, studios, and post production

If time really is money, you can’t afford not to own StereoMonoizer

‘Time is money,’ the saying goes. It’s certainly true in the music creation world, where producers and engineers are constantly looking for ways to streamline and make the process more efficient. For a mixer like me, part of that process involves prepping a session, which can be time-consuming, especially if the track count is large. When I was introduced to StereoMonoizer, I was immediately intrigued. My session prep times have been shaved off considerably. Easy to use features like the stereo waveform display, which allows you to view the stereo content of an entire waveform at a glance, make this a must-have.

I find it challenging to jump from the left side of my brain back to the right. Dealing with mind numbingly boring tasks can make it more difficult to quickly come with your creative A game. StereoMonoizer addresses the issue of importing stems and mix prep head on, saving me time and frustration from the very beginning of a mix. It’s a no brainer; left or right side of the brain.

StereoMonoizer is awesome! In the blink of an eye, this utility analyzes stereo audio files and determines if the file is actually recorded in mono. Then, it automatically places the files into a convenient folder. How great is that?!? This is a BIG time saver and a major DSP saver. It’s a mix engineer’s dream utility and a ‘must have’ for all Pro Tools users. I love it!

Apparently, there is a way to export mono files in Logic. If so, very few Logic users either know how or don’t bother to do it. And by very few, I mean…none that I’ve encountered. I just tried StereoMonoizer and compared the rendered mono file to the original source file in Pro Tools. The result? I’m sold. Any PT user that gets stereo files from Logic, or anywhere else for that matter…that doesn’t buy and use this inexpensive tool is missing out. No longer will I waste time evalauating stereo files manually. This little app could have saved me 3 hours in mix setup yesterday and will save countless hours in the future. Genius. I wish I had thought of it. This is the best $49 you’ll spend on audio software ever.

StereoMonoizer allows me to get right into the mix! By automatically eliminating unnecessary stereo tracks AND allowing me to normalize the audio to the exact level I want, my session prep time is a fraction of what it used to be.

StereoMonoizer is a great product and will save you money over the course of the year … One click and the tracks are sorted, easy as can be.

StereoMonoizer takes the grief out of dealing with the ‘mono-audio-in-a-stereo-audio-file’ files that have become an unfortunate distraction to getting into the music and doing a great mix. Simple to use and very effective!

When I first saw StereoMonoizer, I was excited to have a utility program to deal with the problem of converting interleaved and non-interleaved stereo mixes. I compared the processed and unprocessed files and the StereoMonoizer was completely transparent.

Stereomonoizer is an absolute must have to add to your arsenal of tools for mixing and sound design. It is so simple to use and it eliminates all the guesswork, which in turn has saved me tons of time for prepping sessions. The features are great and being able to convert as many audio files as I want in no time is heaven sent! I highly recommend Stereomonoizer, you will not not be disappointed.

StereoMonoizer has saved me time, but mostly storage space with archiving past projects and tending to an ever-increasing historic library.
