Adding cstring to the includes for SDR.cpp resolves this error:

Hi, cool thing!!

However; Libusb is missing while trying to compile for Mac

This what the compiler says. I did run git submodule update --init --recursive

Package libusb was not found in the pkg-config search path. Perhaps you should add the directory containing libusb.pc'`

re: #29

move towards using git submodules on every platform. Both of those libraries are semi-complex to build, so I'm keeping my eyes open for a plugin that builds stuff along the lines of ext (and dep to some extent) in the main build.

I'm hoping to have this branded the same as my non-GPL modules, but someone could fix the panel layout.

• Ability to "seek" channels like in a fancy car. 🚐
• CV out of scanned channels?

see https://github.com/sysrun/rtl-sdr

DHE-Modules has a branch right now that builds using Appveyor. I'd ask that if we decide to use external scripts we use a standard layout. We could also stand to put Travis scripts in this layout.

• my rough count is that we're getting roughly 20hz resolution with ~100ms audio latency
• possible causes: pthread granularity, usb latency, device limitation

1. Build tag v0.6.0
2. Upload packages to https://github.com/bongozone/vcvrack-rtlsdr/releases/v0.6.0
3. Submit to community repo

Linux blocked by: #26

@davephillips, @dizzisound: want to take a look at this and chime in on the feel of the knob?

Looks like the crash is on pthread_mutex_trylock

see https://github.com/sysrun/rtl-sdr

Should include displaying which device corresponds to each instance of the module

Greetings ! I saw this project and wondered what it's about, so I read up on rtlsdr. I was a ham radio operator when I was a boy (a very long time ago), so I'm excited to read about your work. What's its current status wrt any specific hardware, i.e. can you suggest any particular dongle to buy ? I'm on Linux, btw, if it makes any difference. Anyway, I look forward to the module in Rack, I'll be checking in the project to see (and hopefully hear) how it's going.

this got me closer: mingw-w64-x86_64-libusb-compat-git
this was a help: mingw-w64-x86_64-pkg-config
adding this the the makefile seemed to help, but was probably a mistake: PKG_CONFIG_PATH ?= ./src/sdr

I now get this error:

Package librtlsdr was not found in the pkg-config search path.
Perhaps you should add the directory containing `librtlsdr.pc'
to the PKG_CONFIG_PATH environment variable

A suggestion would be a three-way quantization switch: off, 100khz, 10khz

Probably do #19 at the same time; relates to #5

Fedora 23 Linux
Rack master (0.6.x dev)

Alas, the latest Rack pull causes the following build error. Apologies for the long error list, it seems to be a repeated error (multiple definitions) but I thought I should include the complete report:

[Never mind, I resolved the issue by removing the multiple definitions of RACK_DIR and the plugin.mk include in the Makefile.]

• Use the PulseGenerator builtin class
• Will this output a pulse before the audio from the new channel arrives? Is this bad?

relates to #13

As noted on the FB group page, sched.h is sometimes installed in /usr/include and not in /usr/include/pthread. I'm not sure how you can check for that, but it's an easy fix at the user level.

• normal the audio together unless both channels are active (output.active)

On hold!

rtl_fm increments wb_fm frequencies by 16000.

We should increment our CV controlled frequency by the same so that the displayed tuning frequency matches our day-to-day perception of what the center of FM tuning looks like.

Idea for improving the number of tuning operations per second #8

The current implementation of RtlSdr_tune signals s->hop_m to let the tuning thread know to tune the SDR. Why not try moving controller_thread_fn's mutex wait out of the loop body.

safe_cond_wait(&s->hop, &s->hop_m);

1. Instrument code to count frequency transitions per second.
2. Pop in code that makes step call the tuner every time.
3. Record the performance.
4. Remove the mutex (safe_cond_signal in RtlSdr_tune & safe_cond_wait in the loop body) and record again.
5. Report back here.

In the shipping version of the code, the tuning thread should keep track of what it tuned to and only tune again (ie call optimal_settings & rtlsdr_set_center_freq) if the frequency has changed.

If we're thinking of calling optimal_settings & rtlsdr_set_center_freq directly inside RtlSdr_tune, remember that rtlsdr_set_center_freq will hang Rack & glitch the audio if you call it as fast as you can.

Hi Jon ! I got my USB dongle set up and 'rtl_test -t' returns what it should. However, when I load your module I receive a series of messages with this error:

Reading error; count was 0

The Gqrx radio application isn't working either, so I think I've still a step or two to take before I'm there. Any suggestions what I might have missed ? I installed the rtl_sdr stuff from the Fedora 23 repos, perhaps I should build and install from source instead ?

Linux Fedora 23
Rack 0.5.x

Just a note to suggest that a check & workaround might be a good idea:

📻 RtlSdr_init at sample rate 48000
No supported devices found.
Skipping rtl-sdr intiailization since we dont have a device
Makefile:50: recipe for target 'run' failed
make: *** [run] Segmentation fault (core dumped)

Btw, I love the little graphic on the init. :) Also, I have a dongle on order, should be here by the weekend, I'll be able to test the module then.

• relates to #29
• standard layout

see VCVRack/Rack#258

I could use a maintainer for Windows and Linux packages. Apply within!

Linux: blocked by #26
Windows: @dizzisound built recent rev

rtl_udp or rtl_fm_python allow us to control an rtl_fm process over a UDP or TCP control socket respectively. Leaning towards the UDP implementation as it should be simpler.

Advantages

• Easily allows multi dongle setups; right now rtl_fm has statically allocated structures that need to be converted to be per device. I'm not in the business of refactoring rtl_fm.
• removes threading code; we'll just select on a file handle streaming PCM.
• Additional tuning parameters:
  • controllable with CV: gain, squelch, decoding mode (FM,AM,USB,LSB)
  • controllable with panel control: auto gain enable
  • will require rtl_fm restart (use context menu): dongle index
• Removes hacked rtl_fm code from repository; will be included as a submodule & packaged with zip.
• potentially add other fm decoding modules to the mix
  • redsea - Radio Data Service display
  • darc2json - more radio data
  • stereodemux - STEREO AUDIO
• Moves all that I/O out of Rack
• rtl_fm crashes won't crash Rack
• Allows BSD license for entire module and maintains my copyright, so I can distribute this module linked against my proprietary code for the Pulsum Quadratum module pack.
• Circumvents GPL licensing issues for adding panel graphics copyrighted by me. I will use a license similar to the Fundamental SVGs. See VCVRack/Rack#854
• Fixes static linking issue on Linux #26

Disadvantages

• Neither implementation has a network transport for PCM data, so we won't be able to add an option to stream from a remote dongle.
• Potential increase in latency for both PCM data and tuning. Tuning granularity over time is bad right now; you may only tune ~10 times a second. I believe I also modified the rtl_fm sources to not clear the audio buffer after a tuning event. We may need to include a patch to the rtl_fm implementation to replicate this behavior.

Some ideas:

• include a screenshot
• explain modes of operation
• link to VCVRack
• embed a video
• include compilation instructions

Daniele Zerbini Hi Jon, the makefile works for me, just having to add the env path to pkg-config, and change the libusb name into libusb-1.0 (that's the name of the library installed on Windows). The plugin works, but there are still calls to the external dlls, i.e. if I remove the installed dlls, the plugin won't load. I'll try to investigate some more, may be other win-specific flags could do the trick?

see Wikipedia

The FM broadcast band in Japan uses 76 to 95 MHz. The International Radio and Television Organisation (OIRT) band in Eastern Europe is from 65.8 to 74.0 MHz

What is a reasonable range for all RTLSDR devices?

Will this make manual tuning too difficult?
