Upgrade to Mac OS Max version.
Windows, runtime, standalone, and documentation upgrades still in progress…
This is an interim update to add new drivers.

Reverse engineering FSK radio transmissions from tire pressure sensors
By Jared Boone
Today was able to get the rtlsdr~ object running in Pd on Ubuntu 14.04 on a Macbook pro.
Audio quality seems rough. The only driver I could get to work was Alsa at 44.1KHz – may be able to get help with this from Pd community.
Ended up using 64bit libraries for librtlsdr and libusb-1.0 . In fact, needed to using the shared (.so) libraries, not the static ones (.a) due to a weird linker error. Its possible that it happened due to mixing shared and static and I might try again using both static for these 2 libs.
See notes from previous post about issues with USB capture, and non-root user in Linux – there are 2 flags on the cmake for rtlsdr that might help resolve both of these, but I wasn’t having any luck and needed to use the method described in previous post.
The source code for linux version is in the /usr/lib/pd-extended/extra/rtlsdr~ folder – and the test pd file is in ~/pd/rtlSDR-block.pd, along with some abstractions.
There is also a makefile to build a local version of rtl_fm (rtl_fm3.c) in ~/rtl-sdr-new/rtl-sdr/rtl-fm3/
This makefile mixes the static and shared libs with no problem… hmm…?
next
Need to package this stuff up and send it to pdsdr github with source for Max/Pd on mac and Pd on linux. + instructions… etc.,
Would like to try running on r-pi – but will need to adapt the test patch to receive Osc messages because there is no gui on r-pi
Also I am some skeptical about running at low sample rates for audio – we’ll see…
another note
Just thinking, that even if I am not able to run rtlsdr~ on r-pi that we could adapt rtl_fm so it receives control input from Pd using Osc and work that way…
