Low Recording samplerate in rockbox?

<< < (2/2)

Multiplex:

--- Quote --- even though I resample to 8khz, the single viewed channel in the spectrum viewer mode only tops at 4khz.

That would be the Nyquist Frequency http://en.wikipedia.org/wiki/Nyquist_frequency if you sample at a frequency X the highest frequency you can record is X/2 - so the maxmum frequency a Human can hear is about 20kHz so CDs have a sample rate of about double that - 44.1kHz (I can't rememebr the reason for that exact choice)

This may explain why you have confusion over the stero - it's not double because there are two channels it's double because of Nyquist.

I believe the c200 and e200 series have identical audio hardware, which is why I stated that it's that way on the e200.
