(A UGen is a unit generator, i.e., something which makes sound.) If you want to explicitly tell the server to use the internal soundcard, you need to specify both input and output device. ... //this loads into a buffer the default sound that comes with SuperCollider All content on Designing Sound is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License. {SinOsc.ar(440, 0, 0.1, 0)}.play; Googling, I found this mailing list thread, which wasn't really helpful, it only seems to say "don't worry about 128 channels, that's an artefact of ALSA's API, just default to stereo when requesting output and you'll be fine". they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. What is a sane fallback value if the number of channels is obviously (?) To put it simply, UGens take inputs and use them to produce sound. What does it even mean if PortAudio reports 32 or 128 "channels" for the default audio device, even if the actual hardware is only 2 channel stereo? Hence this issue to get things clarified.). GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. Same on PulseAudio's "default" device with 32 channels. We pass in just one argument, mul, which stands for “multiply.” SuperCollider will multiply the output from the PinkNoise UGen by the value of mul. What is the best way to programatically render a SuperCollider program to a file (say a wav file). Already on GitHub? The following example comes from a MacBook Pro:Server.default.options.inDevice_("Built-in Microph");Server.default.options.outDevice_("Built-in Output"); In case of a dedicated audio interface, you might need to specify a single device, e.g.Server.default.options.device_("MOTU 828"); On macOS you c… Have a question about this project?

As you can see, that value is a little complex: Since SuperCollider outputs its audio signals to the JACK sound server, any other JACK-aware program has the opportunity to record, process, and use them.This portion of the tutorial will help you to record SuperCollider's output in Ardour. SC with PortAudio is known to work fine on Windows, where it is SC's default audio driver. (Things "mostly" work as in one gets stereo sound as expected, but there are some occasional buffer underruns during playback. After digging into the source of SC_PortAudio.cpp, here's an oddity I found: The audio driver sets mInputChannelCount and mOutputChannelCount to the number of channels reported back by PortAudio's Pa_GetDeviceInfo(). The PortAudio library is using the ALSA API. But PulseAudio blocks the hardware devices. Will keep investigating. If you turn off PulseAudio and use ALSA directly, you can tell SC to use one of these hardware devices. But I suspect the underruns are a separate issue to be fixed later, after this issue here about the proper setup of the channel count for the PortAudio API.). After downloading and installing ASIO4ALL you will notice it has been added to the list of available audio devices when Supercollider boots. If I patch SC_PortAudio.cpp and force mInputChannelCount = 2 in line 375 and mOutputChannelCount = 2 in line 384, things mostly work. Due to the advanced nature of SuperCollider, the text assumes that you have a basic knowledge of how to work with Ardour. privacy statement. When on ALSA's "default" device, SC_PortAudioDriver will request an output stream of 128 channels from PortAudio and later write to it, yet audio output remains completely silent. Same on PulseAudio's "default" device with 32 channels. Learn more. too big? When on ALSA's "default" device, SC_PortAudioDriver will request an output stream of 128 channels from PortAudio and later write to it, yet audio output remains completely silent. This is weird, now it works with unchanged sources. SuperCollider is using the PortAudio API. not on my box, an amd64 machine running Xubuntu 15.10 with its default PulseAudio. Please see an discussion on trying to do this in the later entries of #1658. Successfully merging a pull request may close this issue. As previously seen, a sine wavetable oscillator UGen (SinOsc) can be given inputs for frequency, phase offset, output multiplier and add value to output. the mixer etc. And that's what Server.sc seems to think, too. (Please be patient with me, I'm a beginner with the internals of SuperCollider and still learn the terminology. I'm trying to use SuperCollider with the PortAudio driver on Linux. .ar, as always in SuperCollider, means we want audio rate output, i.e., sound. And then it works. We’ll occasionally send you account related emails. So obviously, my whole analysis seems to be wrong. Millions of developers and companies build, ship, and maintain their software on GitHub — the largest and most advanced development platform in the world. PulseAudio provides an ALSA compatability layer. For more information, see our Privacy Statement. The user should be able to select two devices for duplex audio using the same interface supported in MacOS: ALSA without PulseAudio will also provide a virtual device called "default", which claims to have 128 channels for input and output. Here's the list of devices with the number of channels reported on my system (when using PulseAudio): As you can see, for direct hardware devices like hw:*, this is the actual number of audio channels supported by that device, e.g. But to make things more confusing, scsynth's default number of output channels when started from the command line is 8, as defined in SC_WorldOptions.h. they're used to log you in. Instead, a normal user is meant to use the PulseAudio's ALSA emulation device, which provides "default" and "pulse" and offers the benefits of the PA system, e.g.
