Here are two samples from two different USB microphones.
This will work much better if you put on headphones before listening.
Both mics were recorded at the same desk in the same untreated (no acoustic panels, etc.) standard bedroom with bare walls. I read the same short passage from a book into both mics.
The only thing I did post-production was to manually (no compression) make the loudnesses the same. Sometimes a louder audio will be perceived as "better" based on that alone.
Other than that these are raw audio files with no editing - no noise reduction, EQ, compression, de-plosive, de-reverb, etc.
I thought it would be fun to see people which sample people think is which mic (Sample A or Sample B), and maybe your thoughts about it. Leave a comment below. At some point I will reveal what mics these are :-).
