Hello! I've been fiddling with nitro for awhile and love it! The onboard sampling is the highlight for me right now so here's my contribution to try and make it as good as possible (I'm sure it's been done but I took the time to draw this out so I thought I'd post it). This *should* solve the problem of blowing/distorting your samples when using a line-level source like a CD or whatever instead of a mic.
Uses the simple circuit from here: http://www.tkk.fi/Misc/Electronics/circuits/line_to_mic.html
Excellent project and thanks for sharing it.
oh cool, so just much higher sampling rates, which means their's the possibility for a higher quality live input feed (from another, higher quality mic and/or an audio input). Cool. I might look into doing this one day when I have time. Anyway you could make me one and I'll pay for it and you ship it? Or is that asking too much?
no... it's got nothing to do with sample rates...
it's about voltage levels on audio inputs...
microphones produce only tiny tiny voltages, so the input circuits that receive the microphone input are very sensitive...
iPod earphone outputs, for example, are very "high voltage", and plugging those into a sensitive mic input will overdrive it if you wanted to sample something off the iPod.
This circuit reduces the input voltages to levels more comfortable for the audio input circuit in the DS.
