Because we used 2 different recording devices simultaneously (Tascam DR-05 and Sony PCM-D50) we expected some difference in the mic preamps and D/A converters. Sony Internal Mic Frequency Matched to Binauralĭownload audio file (1.0-River-Ambience-Sony-Internal-Mic-Frequency-Matched-to-Binaural.mp3)įor this test we used two different recorders so we can compare the exact recording. Here is the curve that matched frequencies: This will tell us how well the transients are being picked up. Let’s compare what happens when we frequency match and normalize the Sony Internal Mics to the Binaural Microphone frequency curve.

We recorded at 96KHz/24bit and you can download the raw files (well not exactly raw – flac) at the bottom of this post. This was a good opportunity to record ambience with a lot of detailed information to highlight transient response in the test microphones. We drove around until we found a location near Deep Cove with a large stream, away from busy car traffic. River Ambience Recordings in North Vancouver
Plus I thought it would be a good excuse to hang out with Gordon 🙂 Sound Designer Gordon McGladdery mentioned something about binaural microphone recordings and I jumped at the chance to do a comparison recording.

I’ve read the microphones on a Sony PCM-D50 Portable recorder are not great and I was wondering exactly how “not great” they might be.
