<div>Hey! So, I got asked by Sparkfun to do a video for the
Tsunami, so I went ahead and made a module with it! It's
indeed an awesome little board, check it out:<br>

Would love to help, but at the moment I can't due to
legalities.<br>
If someone does make one, I'd be very interested (depending
on spec).<br>

Hi,<br>
<br>
Yes, it looks like an interesting little board. What
is that<br>
impressive though?<br>
I didn't know about this particular codec, it could
be handy in a<br>
module design. Now if I put aside SDIO throughput
(which I don't<br>
know much about), it doesn't seem that surprising to
be able to read<br>
32 samples at the same time. We can already achieve
32+ linearly<br>
interpolated voices on an STM32F4 (Cortex-M4 @
200MHz) at 48kHz, and<br>
the M7 has far better performance (300MHz, better
FPU) so there<br>
should be room for better interpolation (or more
polyphony). Am I<br>
missing something?<br>
<br>
Best,<br>

That's impressive!<br>
<br>
It's usually the resampling that takes the
majority of CPU cycles<br>
with sample playback. So for a given amount of CPU
power you can<br>
either have tons of voices that alias like hell
when you transpose<br>
the samples or a quarter of those voices with nice
clean detuning<br>
of the samples. I suspect this is where they might
have cut<br>
corners.<br>
<br>
Of course if you want to pitch up a Hi-hat sample
and the playback<br>
module has crap resampling, then there's nothing
to stop you<br>
transposing the sample in a decent audio
processing package first<br>
before sticking it on the sd card. (That's what I
used to do with<br>
my old Akai S01 sampler that had crappy linear
interpolation, and<br>
turned hi-hat samples into rustling paper bag
sounds as soon as<br>
you touched the transpose control!)<br>
