In this stereo recording shootout I test two different stereo recording techniques. One, a mid-side (M/S) stereo setup costing over $2000. The other, a pair of inexpensive stereo omni-directional mics.
Can these $100 microphones compete against the higher priced alternatives?
So, join me for this stereo recording shootout as I record the sound of nature.
The Location
I recently visited the Welsh countryside and took the opportunity to record the sounds of nature.
Understandably, it’s difficult to make good recordings near cities or towns. For example, traffic, and other noise can easily ruin recordings.
So, while I had the chance I compared two stereo recording techniques.
Read on to find out how I made the recordings.
Listen to the results
In the video below I explain the different recording methods. I also play you examples of the recordings. Subsequently, you can use your own ears to judge which technique works best.
Mid-Side Stereo Recording
Firstly, the mid-side stereo setup. This technique is a often preferred for natural ambiences. However, it does require some extra work in post production.
M/S recording usually requires two microphones: one for the ‘Mid’ and one for the ‘Side’.
I used the Sennheiser MKH60 for the ‘mid’ microphone. The super cardioid polar pattern makes it ideal. Secondly, I used the Sennheiser MKH30. The figure of 8 polar pattern captures the ‘sides’.
The MKH30 was mounted above the MKH60. Lastly, I connected each microphone to a Tascam DR-70.
Stereo Omni-Directional Microphones
I made the second set of recordings with a pair of Clippy Microphones. These inexpensive mics are available from Micbooster.com.
The Clippy’s use Primo EM272 omni-directional capsules. These capsules have both low noise and high sensitivity. Therefore making the Clippy’s ideal for nature recording.
I connected the Clippy’s to my Sony M10 field recorder.
The Clippy’s were placed around 20-25cm from each other. The average distance between human ears is about 20 cm. So, I find this produces more realistic recordings.
Post Production
With most M/S recordings, you must decode the signal. This step is vital to get the best results. The best way to do this is by using a M/S plugin. These two are free: MSED by Voxengo and Mid Side Matrix by Goodhertz.
Stereo recording shootout: The Conclusion
In short, both recordings are great. I was very pleased with the sounds I captured. However, which did I prefer?
Firstly, the mid-side recording has good space and depth. In addition, a well balanced tonality.
Similarly, the stereo omni mics also performed well with a natural, open sound. They really provide a sense of immersion. Although in my opinion they didn’t seem to capture distant sounds quite as well as closer sounds. Ultimately, I preferred the M/S recordings.
Regardless, I was still impressed with the Clippy’s. Especially considering the difference in price!
Why not take a listen for yourself? Let me know which recording you prefer.
