Looking for Linux version of Rubber Band Library

2010-07-20T05:32:48+00:00

Hi All,

I am looking for linux version of Rubber Band Library. I want to use it as command line utility.

I have downloaded sourcecode from "http://www.breakfastquay.com/rubberband/", how ever make is not successful. It gives package missing error.

Please help

Best Regards,

Small fix to DSSIVSTPluginInstance

2010-07-05T11:01:33+00:00

In case when instantiating the RemoteVSTClient, the server process crashes, on plugin release we free m_alsaDecoder, which may not be already allocated.

By adding m_alsaDecoder(0) in the initialization list of the DSSIVSTPluginInstance constructor:

DSSIVSTPluginInstance::DSSIVSTPluginInstance(std::string dllName,
                     unsigned long sampleRate) :
    m_sampleRate(sampleRate),
    m_lastSampleCount(0),
    m_controlPorts(0),
    m_controlPortsSaved(0),
    m_controlPortCount(0),
    m_audioIns(0),
    m_audioInCount(0),
    m_audioOuts(0),
    m_audioOutCount(0),
    m_programs(0),
    m_programCount(0),
    m_alsaDecoder(0),                      // <<<<<<< add this here
    m_pendingProgram(false),
    m_plugin(0),
    m_ok(false)
{
   // ...

We fix a potential crash in the destructor:

DSSIVSTPluginInstance::~DSSIVSTPluginInstance()
{
    std::cerr << "DSSIVSTPluginInstance::~DSSIVSTPluginInstance" << std::endl;

    // ...

    if (m_alsaDecoder) {
    snd_midi_event_free(m_alsaDecoder);     // <<<<<<<< to fix a crash here
    }

Here it is the backtrace:

Remote VST startup failed: Failed to open FIFO

I'm getting this error everytime i try to start a vst, no matter which. i'm using the 0.8 version on a realtime patched gentoo system with wine-1.1.24 . Also trying to run it as root, no sensible changes (same output here).

dssi-vst package for deb: which wine version?

2010-06-28T20:10:47+00:00

Hi,

at last it is there (well, actually, it has been there for quite a while now): a package to install dssi-vst via apt-get.

Current version available online is 0.8-2+b1.

I have had some trouble with running a certain online registration tool for my B4II organ. To do this online registration correctly, I need the very latest vesion of wine to be installed, which on the wine-hq pages is wine_1.1.42~winehq1-1_i386.deb. The trouble with the registration tool is that it needs some VB runtime libs to be installed of which I neither know which version nor where to get it. So I have installed that latest wine version and - you name it - the registration tool works and I can do the online registration successfully.

Unfortunately, when installing dssi-vst to run my B4II organ plugin I have to uninstall the wine-hq package and instead install the apt-get package in debian repositories. I cannot keep the latest wine version. I also cannot install experimental version or wine-unstable version.

dssi-vst appears to be hooked to a particular version of wine and I have no idea how to circumvent that.

Maybe it could be an idea for the maintainers of the package not to tie dssi-vst to a particular wine variant?

Kind Regards,
Crypto.

Compiling fat binaries on OSX

2010-05-20T13:14:07+00:00

Hi, I'm trying to build the library for more than one architecture. It seems that the current makefile is not compatible, but I'm not sure what to change about it.

I think the problem is with the ar program, since on OSX you should be using lipo or libtool instead I think. This seems to be the offending bit:

$(STATIC_TARGET): $(LIBRARY_OBJECTS)
$(AR) rsc $@ $^

Below is the error I get.

ar rsc lib/librubberband.a src/rubberband-c.o src/RubberBandStretcher.o src/StretcherProcess.o src/StretchCalculator.o src/base/Profiler.o src/dsp/AudioCurveCalculator.o src/dsp/CompoundAudioCurve.o src/dsp/SpectralDifferenceAudioCurve.o src/dsp/HighFrequencyAudioCurve.o src/dsp/SilentAudioCurve.o src/dsp/ConstantAudioCurve.o src/dsp/PercussiveAudioCurve.o src/dsp/Resampler.o src/dsp/FFT.o src/system/Allocators.o src/system/sysutils.o src/system/Thread.o src/StretcherChannelData.o src/StretcherImpl.o
ar: lib/librubberband.a is a fat file (use libtool(1) or lipo(1) and ar(1) on it)
ar: lib/librubberband.a: Inappropriate file type or format

Compiling on OS X 10.6.2 -- need pkg-config

2010-05-04T04:13:14+00:00

Heads up to Mac users, autoconf started bitching at me about pkg-config not being up to date or in the right place. Not too big of a deal.. just download from http://pkg-config.freedesktop.org/wiki/, then ./configure && make && make install the pkg-config stuff and you should be good to go, it's just another dependency that's not listed in the readme.

Stretch ratio and RubberBand abilities

2010-01-30T00:53:15+00:00

Hi BreakfastQuay team,

I started a new project using your amAZing library but I experience some difficult to clearly understand few things.

I usually get a "*** WARNING: increment -21 <= 0, rounding to zero", what does it mean ?
Example given at 44100 sample rate with a stretch ratio 0,38 and working offline (with all other default options).

My second question is, with a ratio strictly equal to 1.0 (double value, like in your API) when I 'study' next 'process' a buffer of 22050 samples, I get an output response length around 22160.
Is it 'normal' ? (I suppose yes because timestretching is not an exact 'science' ;)
But, does this error range approximation grows with stretch ratio ?
Sometime I received lot of "Buffer overrun on output" I can't handle, and 'vice et versa' lot of missing precious frames comparing to my output length forecasts (buffer underrun for me).

Thank's a lot for your great great job with this (vital to me) lib :)

Regards,

Christophe

VSTHost launches Jack with bad parameters

2010-01-05T21:19:29+00:00

Hi there

After installation, dssi-vst works fine, but "vsthost any.dll" (for instance) launches jack with basic parameters that are not those from -jackd, so I can't use it for playing. Where can I find configuration files for vsthost ?

Compilation woes on debian

2009-12-29T21:00:31+00:00

Hi,
I'm trying to compile dssi-vst 0.8 on my sidux (debian sid) notebook. It's a 32bit version of debian.

After I enter the source file directory and enter "make" from command line I keep getting:

lutz@pucki:/home/data/pcsetup/dssi-vst-0.8$ make
wineg++ -m32 -Ivestige -Wall -fPIC remotepluginclient.cpp -c -o remotepluginclient.w32.o
remotepluginclient.cpp: In constructor ‘RemotePluginClient::RemotePluginClient()’:
remotepluginclient.cpp:41: error: ‘sprintf’ was not declared in this scope
remotepluginclient.cpp:50: error: ‘perror’ was not declared in this scope
remotepluginclient.cpp:64: error: ‘perror’ was not declared in this scope
remotepluginclient.cpp:78: error: ‘perror’ was not declared in this scope
winegcc: g++ failed
make: *** [remotepluginclient.w32.o] Fehler 2

Note that I have installed wine-unstable because the "Service Center" application that I need to online register my B4II does not run with the standard version of wine. I have liblo0 installed and all dev packages mentioned in the README file of dssi-vst.

I had to de-install standard wine and that is why the *.deb package of dssi-vst v. 0.7 was deinstalled as well, as it requires libwine and wine (without "unstable") to be installed. Because I cannot use the *.deb package of dssi-vst that I already have I wanted to compile the latest version of dssi-vst myself, but without success, obviously. This dssi-vst deb package used to work well until I tried to register my B4II.

I have read quite a bit about adding new lines to the source files, but I have not found what to do there exactly.

Can you help me here?

Thankyou in advance,
Crypto.

Problems compiling dssi-vst in ubuntustudio 9.10 (solved)

2009-11-27T15:55:25+00:00

Hi!
I succesfully compiled dsi-vst after a clean install of ubuntustudio 9.10.
but I encountered some problems, luckily solved in the end.

dssi plugins were installed during US installation.
wine is installed by default but I had to run winecfg (emulate Windows XP and choose alsa in the audio tab).

I installed the following packages from US:

build-essential
wine-dev
liblo0-dev
dssi-dev (this one installed libjack-dev and libjack0100.0-dev)
libasound2-dev

I checked the paths of dssi and ladspa, then I edited the makefile and now DSSDIR and LADSPADIR are /usr/lib/dssi and /usr/lib/ladspa, respectively.
I also changed the BINDIR to /usr/bin/ but I think this is irrelevant and it is more correct leaving it alone (usr/local/bin), as this is a local installation (I am not sure about this)

Then, it didn't compile! It seems that some C++ functions (sprintf and one or two more) need 'cstdio'.
gcc version is 4.4.1 (Ubuntu 4.4.1-4ubuntu8) .

To solve it, in these files:

remotepluginclient.cpp
remotepluginserver.cpp
rdwrops.cpp
remotevstclient.cpp

I needed to add:

#include

Thanks a lot for this great piece of software!

Error installing Rubberband from source (but solved it)

2009-10-13T07:29:49+00:00

I tried to install from source but the "make install" gave me an error about not finding "src/vamp/vamp-rubberband.cat" .
After going into the src directory and doing "ln -s ../vamp ./" and "ln -s ../ladspa ./" I got a successful install (so it seems)

Now compiling sonic-visualiser

Compiling RBL for Windows

2009-09-11T15:42:32+00:00

Hello,

I'd be very appreciative of any help I can get with compiling Rubber Band Library on Windows. I'm a noob.

I first started off with trying to get it to compile using Visual Studio. I felt I was going nowhere, so I scrapped that effort. I was able to compile libsamplerate (SRC) this way, so I initially went with the same approach.

Then, I went to cygwin. Right now, I'm stuck during ./configure at:

"checking for SRC... configure: error: Package requirements (samplerate) were not met: No package 'samplerate' found"

Looking at config.log, it appears that pkg-config is looking for samplerate.pc. I know nothing about linux, but isn't this something that only exists on linux platforms? I mean, I have the libsamplerate.dll ready, but it seems like I need to provide the source plus the C++ and linker flags.

Will I run into similar problems with FFTW3, Vamp, LADSPA, etc..? With my limited knowledge, this seems like a nightmare.

So, my questions are: is there a better way to do this? The windows executables are already being provided; can you share build instructions / hints?
or better yet, can you provide a Windows DLL? I'm really only interested in using the library, so if I could abstract away all this other stuff, it would make life easier. Plus, RBL may see more adoption if Windows users had easier access to it :)

Thanks!

Performance

2009-05-29T21:23:44+00:00

Hi,

For the first time I tested the rubber band rubberband pitch shifter Ladspa plugin together with jackd (qjacktl) and jack-rack. I tried both the mono and stereo plugin, but I did leave those two options (first one "Faster") untouched.
I used my Electric five-string violin Alien Reiter (from Czechia) for some live test. I had some minimal latency problems (compared to other plugins, but as said "Faster" is untested) else it worked really great! I tested one octave low and high.
I have no problems on my AMD Sempron 3600+ based problem but this machine is no good for mobile use (too big mainly).

I also have a MSI wind U100 where I tested tonight some plugins and they needed max. about 20% CPU power without signal stream (this is already somewhat strange). I found out though that the rubberband plugin quickly steps up to 80% and in the next few seconds to 100% and then the qjackctl "RT" shows e+02 or something like that. At this moment the machine is nearly to slow to even move the mouse with touchpad. Any idea why without stream the performance is already this high ?

Is there anything I can do to make this plugin usable on such a machine ? CPU frequency itself is not that slow. I use an external USB soundcard by Roland (Cakewalk UA-1G) and I can usually at least use one plugin with my electric violin without performance problem (5ms latency with that card).

Thanks for all tips and kind regards,

Reinhard

VST plugin compatibility information

2009-03-20T21:49:59+00:00

Users of dssi-vst should be aware that there is a compatibility list for VST plugins on Linux available for reading and editing here:

http://ladspavst.linuxaudio.org

The site lists reports about native Linux VSTs (which are fewer in number, but... well... native) with reports about running Windows VSTs using dssi-vst and fst (a standalone Window VST cross-hosting application). Look for references to dssi-vst and/or Wine to identify reports that may be relevant to dssi-vst users.
