Thanks. That's good to know. I don't think it should be necessary,
but it's better to know.

Great!
But--when I took out the /usr/local/lib from my ld.so.conf, it still
compiled and linked okay, *and* it switched to using the rpath like your
used to.
Progress, I suppose :-)

Vincenzo,
I don't think this is possible. The smallest size is a byte,
so you can think of your bits being either unpacket bytes
(ie having values 0 or 1), or packed bytes (in which case
you have to unpack them inside your new block).
If I were you I would go with the former method, since

After thinking a bit, this is wrong: the proper (re-)quantizer is
just the MSBs of the original sample---one wants a mid-riser
quantizer to use the even number of output levels symmetrically.
Revised patch attached (still untested).

I should call sizeof( what? )

I'd also like quantization to less than 8 bits. Attached is
a rough diff for rx_buffer.v that aims to support 4, 2, and
1-bit quantization.
