Comparison of Chord CM05 condenser mic and Pulse PM800S dynamic mic
Let me say just a little follow up. I tried to compare this mic (Chord CM05) with another mic - Pulse PM800S.
PM800S is a dynamic mic which I found on a page listing budget but still quality mics
The Noizeworks Product Guides: More Mic For Your Money. Budget Mics Product Guide. Part 1: Dynamic Vocal Mics.
I bought it on eBay for half price compared to Chord CM05.
I used an app in my phone to generate simply sinusoidal tones of various frequency (250, 440, 1000, 3000, 10000Hz) and recorded it Chord and then by Pulse. I put the phone right in front of the mic and there was no noise source in that direction. I'm using focusrite scarlett 2i2 2nd gen as recording device (at 24bit and 96kHz) and recorded a few secs each time.
I looked at spectrogram of both recordings (window size set to 16384 to get more detailed resolution at frequency axis) and found out a little bit less intensity of higher harmonics, but what surprised me more - significantly more low frequency noise. See images below:
Low frequency noise, recording 440Hz
Low freq noise, recording 1kHz
Higher harmonics, recording 1kHz
Am I somehow misinterpreting results or did I something wrong about the way I tested it?
If I'm right, it surprises me a bit. I actually expected better quality from Chord (as it is condenser mic).
As for real usage (recording voice), I perceived the sound of Chord a bit better than Pulse - more clear (but it might be just auto-suggestion because Chord was more expensive). Also Chord has a bit better suppresion of handling noise (but it does not directly relate to sound quality itself).
