Purchased this to record a couple of phone interviews to include in a video for work. The quality was horrible. There was a "flutter" that would happen only when someone was talking. This happened on two separate recordings. The files are 8khz, 16 bit. Today, I used Google Voices recording feature and it worked great. The file is 11khz, 32 bit and crystal clear. Best of all, Google Voice is free. Dont waste your money.
