Want to record to an Android app with something a little better than your phone’s built in microphone? Do you want to use an XLR microphone that rejects more background noise and focuses on the sounds that you want recorded?
Unfortunately, most Android devices don’t come with an XLR jack for you to plug in your professional XLR microphone. Most Android devices do, however, have a TRRS jack. TRRS is a 4-contact version of the common 3.5mm stereo headphone jack. The extra contact allows a microphone input to be included. Do you want to use an XLR microphone that rejects more background noise and focuses on the sounds that you want recorded?
One of the simplest ways to record to any Android app using an XLR microphone is to use an XLR to TRRS adapter. Personally, I prefer an adapter that also has a jack for me to plug in a pair of headphones as well. You can purchase these adapters on Ebay or Amazon, but http://www.kvconnection.com/ has a fantastic selection with great explanations.
Devices used in the following tests:
- Rooted Samsung Galaxy S3 (international)
- TRRS to XLR Adapter(with headphone jack)
- Heil PR-40 Microphone(w/ shockmount, pop-filter, and broadcast arm)
The first clip was recorded directly to the SoundCloud app through it’s recording interface:
Here is the result:
Next I recorded using the Audio Evolution Mobile App:
Here are the results:
In conclusion, the TRRS adapter is a great way to record to a wide selection of Android apps while using a high-quality XLR microphone. The previously mentioned method of recording via a USB interface would also work for getting audio from an XLR microphone into your Android device, but it only works with one, very simple app. The TRRS adapter allows the XLR microphone to be used universally as the primary microphone for the entire device. If you are looking for a simple way to universally record to most Android apps with an XLR microphone, look no further than the simple, but effective TRRS to XLR adapter.
