SpiralSound is open source software, distributed under the General Public License (GPL). See the file COPYING.
See https://github.com/edgeeffect/spiralSound for more details.
SpiralSound is the same codebase as good old SpiralSynthModular reduced down to a library to achieve the same results programatically rather than using a GUI.
Where SSM was a straight software modular synth, SpiralSound is more of a kit for building your own soft-synths.
Whilst I'm doing the basic reworking of SSM into SpiralSound - there's a lot of GIT history rewriting going on. If you check this code out don't be surprised if when you come to do a PULL everything goes kerpooie!
I can't be asked with all that GNU autotools stuff. But as this is more of a construction kit than an application in itself, it shouldn't take you that much time to work out which libraries to link and where they live.
To compile the demo program cd into the demo directory and run make.
At least in prototype versions of spiralSound, I'm using libao to output the sound. This is available in most Linux distributions.
Needed to handle MIDI signals - if you're not going to use MIDI, you'll not need this or libpthread
Part of GLIBC (or uClibc) posix threading library needed by alsa sound library and spiralSound's MIDI code
Part of GLIBC (or uClibc) library of C maths functions
The original SpiralSynthModular used LADSPA to provide extra plugins.
http://plugin.org.uk/releases/lrdf/ http://www.redland.opensource.ac.uk/raptor/
If you have the lrdf library installed on your system, the LADSPAPlugin will automatically use it.
To disable detection of this this, use the configure option: ./configure --disable-liblrdf
If you have jack installed on your system, you can use it via the JackModule.
To disable detection of jack, use the configure option: ./configure --disable-jack
http://www.zip.com.au/~erikd/libsndfile/
If you have libsndfile installed on you system; PoshSampler, Streamer, and SpiralLoops load any audio format/file that libsndfile can.
To disable detection of this, use the configure option: ./configure --disable-sndfile
(This info can be added to your own programs - this section of the readme needs updating)
This file contains all the setup variables for the program. Thes values can be edited with the options window whilst running SSM. The following variables in the are the ones to play with to get a good playback on your machine. This is usually tradeoff between quality and responsiveness (latency). You can build designs and songs at low quality (22050 samplerate etc) and then record them at higher settings. The wav file will sound fine, even if the realtime output doesn't.
BufferSize = 512 - Size of sample buffer to be calculated each cycle.
FragmentSize = 256 - Subbuffer size sent to the soundcard
FragmentCount = 8 - Subbuffer count, -1 computes a suitable size,
setting to 4 or 8 gets better latencies.
Samplerate = 44100 - Sets the samplerate
