iFP-895 MP3 encoding quality

I was curious if anyone would consider the 16 kHz limit that is present on the iRiver iFP-7/8xx players when recording a significant issue? Personally I don't really mind it, but I figured I might ask around a bit. Could this just be a lazy way to avoid sfb21 problems?

This clip was taken while walking around a park with the mics just plugged directly into the iFP. The mics themselves are a pair of Panasonic WM-61B capsules soldered to a headphone cable. I was wearing them like earbuds, they're wrapped in a bit of foam cut from the pads of the 'phones I butchered to get the cable. Needless to say, the binaural effect doesn't work unless you're listening with headphones.

The clip was trimmed down to 30 seconds with MusiCutter BTW.

If you don't mind the 16kHz lowpass, what do others' opinions matter? You are using the player, you should decide what is acceptable.

I have an 899 and wasn't aware of it. Saying that I rarely use it for recording and when I do it tends to be line-in from CD/Vinyl/etc. Does the limit apply on line-in recordings? If it does I haven't noticed it, but my limit is about 18KHz (I'm old!) so maybe I wouldn't...

The 16 kHz limit effects both line-in and mic-in.

Just because I don't mind the 16 kHz limit doesn't mean it's not an issue for other people: you wouldn't want to listen to a recording mastered by someone who's deaf in one ear and mostly so in the other and only uses $1 headphones bought from Dollar General would you?

I noticed this about 2 years ago when I bought my IFP-380T, but only after looking at a spectrogram, and only because I was curious to see where a hardware encoder would lowpass. In real life, though, I doubt I'd be able to pick out the 16kHz lowpass on the majority of the LP's and tapes I encoded with the player at 320kbps. Everything I've encoded with the iRiver sounds great, and that's all I really care about
