High Performance SDR ( http://hpsdr.org ) has been working on a high
end audio interface for SDR (up to 192 kHz bandwidth at baseband, I/Q
delivery over USB 2.0). It has a PWM modulator, and even a microphone
hookup and codec for microphone and speakers.
The set of boards required is Atlas (because it holds up all of the
experimental boards), Janus (because he was god of doorways, beginnings
and endings), and Ozy (short for Ozymandias, the Shelley "ode"-ed king
of old). The Atlas backplane/bus is REALLY expensive. I don't know if
most can afford its $28 price tag. Janus is $179 and Ozy is $149. That
is cheaper than a really high end sound card. The Janus uses the
AKM5394A, the best audio A/D around so far as I can tell. It is used in
the Lynx Studios sound cards, the creative Emu, and in the Flex Radio
5000 series, all with good reason. (see http://www.tapr.org
Beginning late this summer, but not before, after we get GnuRadio to
actually run on the PS3, I will work with Frank and others to make this
work. It uses libusb and I do not foresee major difficulties. I think
we need intially to do a user space interface and then have an alsa
plugin to access it. Thanks to Frank for pointing out the obvious. If
anyone else wants to tackle this, jump all over it.
