For this example, we will use "a11wlk01.wav" because it's readily available. ... a float of the current sample's sample rate, embedded into the SynthDef as a constant. Before 1 second has passed, our table would have been read almost 48 times, creating 48Hz audio signal instead of 1Hz. ServerOptions.inDevices; // input devices Remember: SuperCollider is object oriented, and in most cases, even if we don’t think about it, we are dealing with objects. Synth(\sampleSource, [freq: ~midinotes[i].midicps, bufnum: buf]); If non-nil the server app will attempt to set the sample rate of the hardware. Examples On other systems, such as a Mac, you can simply copy MIDIFile.sc into your SuperCollider Extensions directory (typically [$HO… SuperCollider. SC's syntax is an OO programming language, with a syntax mixture of C++ and Smalltalk. Notice that the path to the sample is relative to the sounds/ directory, not to SuperCollider's own directory. 0.5, Pn( Its default value is 64 though it can be set to any value between 4 and 256.

Here we will use PlayBuf, which doesn't allow looping over a specific region. }, '/n_end', s.addr); p.stop; The use of Ptpar above means that you could stop or start only the whole ball of wax at once, with no control over the three layers. RecordBuf.ar(car, bufnum, loop: 0, doneAction: Done.freeSelf); ).play(quant: [4, 3.5]); Set contiguous ranges of sample indices to single values. ServerOptions.outDevices; // output devices. \amp, Pexprand(0.1, 0.5, inf), It is a virtual ASIO driver, communicating with the soundcard using Windows' native APIs. The hardware has to support the sample rate that you choose.. verbosity. See /usr/share/SuperCollider/Help/MIDIFile/MIDIFile-samplepatches.rtf for example usage. To synchronize patterns with a sampled loop, the basic procedure is: Use an external audio editor to identify a segment of the source file that loops in a musically sensible way. 0. This can be set in Windows's Audio Control Panel. A value of 0 is normal behaviour. This helps to support sample-accurate scheduling; however, messaging latency from the SuperCollider language will drift over long periods of time. ) Sound Synthesis 1: Additive, Subtractive, Modulation 3. Plugins are not to be confused with quarks, which are libraries for the language. ServerOptions also allows you to specify other important parameters of the device - the sample rate and hardware buffer size. \rate, Pfunc { thisThread.clock.tempo / originalTempo } Both Realtek audio driver and ASIO4ALL driver have been updated. 0. The number of channels and frames will have been determined when the buffer was allocated. Pfindur(4, Control rate ugens thus use fewer resources and are less computationally expensive than their audio rate counterparts. MME, WASAPI, ASIO etc.) Its default value is 64 though it can be set to any value between 4 and 256. \bufnum, b, If you want to explicitly tell the server to use the internal soundcard, you need to specify both input and output device. o.inDevice_("Windows WASAPI : Microphone"); Looping sampler with crossfading by coreyker on 16 May'16 04:56 in Looping sampler with crossfading.

If you use two analog I/O only, they will be effectively sampled at 88.2kHz, but at the input, every other sample is discarded and at the output the same value is written to the (2n) and (2n+1) samples, so Sc will always see those at … \dur, 1 var initPulse = Impulse.kr(0), To match the loop tempo with sequencing tempo, we need to know both: Original tempo: The duration of the segment chosen in part 1 is 3.185917 - 0.404561 = 2.781356 seconds. \amp, 0.4, We need a good place to chat. ( Control rate. See the Quant help file for details on specifying the onset time of a pattern. The SuperCollider 3 Synth Server is a simple but powerful synthesis engine. This reference provides information on audio device selection, including platform-specific details. Set individual bins of FFT chain in SuperCollider. Of course we can’t be sure that this is the tax rate forever, or in different countries, so this needs to be an argument that can be set in the different contexts. "done recording".postln; 0. originalTempo = beatsInLoop / (end - start); }; But that function isn't needed for this example:( A hybrid approach is used here, where Pbind calculates the lower buffer number to use and the SynthDef calculates the crossfade strength. This reference provides information on audio device selection, including platform-specific details. ) Non-Zero Crossing Edit 52 7.1. The check for sample rates only works on OSX 10.7 and later as system_profiler didn't include sample rate info until that version. It is free and open source software available for Windows, macOS, and Linux. Support for running in real-time is currently in progress. The sample rate of the buffer will be the sample rate of the server on which it was created. var exc = PinkNoise.ar(amp) Gitter has been nice, Slack would probably be just as good. ) These quarks (SuperDirt, Dirt-Samples, Vocal) all appear to install correctly in SuperCollider v3.7+. \time, Pkey(\dur) / Pfunc { thisThread.clock.tempo }, ) TempoClock.tempo = originalTempo; This would stop the pattern, except Pn repeats the Pfindur infinitely, placing the accent in the right place every time. The UGen. actualSampleRate A floating-point number representing the current hardware sample rate, which may drift. The following example comes from a MacBook Pro:Server.default.options.inDevice_("Built-in Microph"); Specific devices can be selected through an instance of ServerOptions.To access ServerOptions instance of the default server, you can use Server.default.options.ServerOptions also allows you to specify other important parameters of the device - the sample rate … It might provide better performance with built-in soundcards and it should allow for multichannel operation with such devices (if supported by the hardware). }, '/n_end', s.addr); The .ar here, and everywhere in SuperCollider, means that we’re going to send signals out from this object at audio rate. "Built-in Output" Output Device Streams: 1 0 channels 2 SC_AudioDriver: sample rate = 44100.000000, driver's block size = 512 SuperCollider 3 server ready.

( fork { macOS provides a way to combine multiple physical devices into a virtual Aggregate Device. When in Supercollider, all the channels are treated as if they were at audio rate. SuperCollider sits on the back-end of a few live coding-specific languages, including FoxDot, TidalCycles (with SuperDirt), Overtone, ixi lang and probably some I've forgotten, but within SuperCollider there is ample support for live coding in the form of various libraries and techniques (I use JITLib), and I've been using it since 2014 … This page collects short and simple code examples of useful stuff. SuperCollider has class browsers and other built-in approaches to snooping on source code ... (BufRateScale scales the speed, in case the wavefile has a different sample rate to the server) Play a file straight off the disk Load it outside the synth so it can be reused. \freq, Pfunc { |ev| ev.use(ev[\freq]) }, Dit wordt gemeten in Samples per seconde. The sample rate in audio determines how many times within 1 second the signal is being measured. // which equals // log() / log() == log(val/a) at base (b/a) This is a basic spatial audio tool using source oriented vector based delay and amplitude panning as well as basic room simulation.

Array of buses in superCollider. If the loop boundaries are wrong, then the musical result will not make sense. if(i == 0) { i } { An integer representing the nominal sample rate of the server; in other words, the sample rate that was requested of the server when it was booted. Both Realtek audio driver and ASIO4ALL driver have been updated. Extra effects + SuperCollider help file description Waveloss (parameters: #waveloss) Sequence individual loop segments alongside other patterns. Choose these values carefully. SuperCollider is an environment and programming language originally released in 1996 by James McCartney for real-time audio synthesis and algorithmic composition.. This repository demonstrates how to write UGens for SuperCollider using a series of examples. SuperCollider access sample rate in a synthdef. The segment beginning (0.404561) and ending (3.185917) are important. If ASIO driver is available, it is probably the best choice to ensure low input/output latency. Een scope met een hoge sample rate kan namelijk signalen meer gedetailleerd meten en weergeven. 0. 1 for original 2 for half, 3 for a third and so on. SuperCollider has documentation in the HTML format available in the supercollider-doc package. Note: If the buffer's sample rate is different from the server's, you will need to.

SuperCollider access sample rate in a synthdef. ), The loop actually starts with a half-beat anacrusis, so Ptpar delays the bell patterns by 0.5 beats. This class can be used as an argument to a Patch. This manual page documents briefly the scsynth command, the audio server of SuperCollider. Server.default.reboot; You can programmatically obtain a list of available audio devices without booting the server:ServerOptions.devices; // all devices ).play(protoEvent: samplerEvent); How to create and play a vector from samples … if(div == 1) { i } { Let's pick the tool that will best help build the SC community. p.stop; bufCount = ~midinotes.size; s.sync; The sample plays at a given frequency at normal rate, so to play a specific frequency, frequency / baseFrequency gives you the required rate. Supercollider discography and songs: Music profile for Supercollider. By default, SuperCollider on Linux uses JACK, and the audio device selection is managed by the JACK server. This manual page documents briefly the scsynth command, the audio server of SuperCollider. Sequence individual loop segments … The standard sample rate used for audio CDs is 44.1 kilohertz (44,100 hertz).That means each second of a song on a CD contains 44,100 individual samples. the def will be resuable for all samples of that sample rate, and will be slightly more efficient. \instrument, \oneLoop, env = EnvGen.kr(Env.linen(0.01, time, 0.05, level: amp), 2) }; For delay lines, I prefer MSP, simply because you can modulate the delay length at the sample rate. ], 1).play; Waves: Sampling Rate and Bit Depth 48 6.3. // one loop segment \amp, Pseq([0.3, Pn(0.1, inf)], 1), 2.

The \ plays the same role in SuperCollider syntax that the : does in Ruby and Clojure, so \instrument in SuperCollider means what :instrument would in Ruby or Clojure. playbufs = PlayBuf.ar(1, bufBase + [buf1, buf2], freq / basefreqs, loop: 0, Audio is unaffected in other applications prior to opening SuperCollider (e.g., Audacity, Spotify, Facebook, YouTube). "SC_JACK_DEFAULT_OUTPUTS".setenv("system"); By default the server will boot to your system's default audio devices using MME driver (which usually means higher latency). Interpolation is cubic. The loop-segment player should provide a rate parameter, where the rate is desiredTempo / originalTempo. SuperCollider access sample rate in a synthdef. p = Pbind( This is only meant for setting a few samples, not whole buffers or large sections. Fixes issue sonic-pi-net#87 SuperCollider can't boot if the sample rates do not match. \instrument, \bell, In Supercollider, data is played as it is generated. \instrument, \sampler, TempoClock.tempo = originalTempo; Here is a list of valid sample rate/bit rate combinations for MP3. ).play; // identify the buffer numbers to read log(val / a) / log(div) + i - 1 What is the simplest way to play a sample/tone with given tempo in SuperCollider.

For that, Phasor and BufRd are probably the best choice. 0. }); }.play; \amp, 0.2, ( At this point you will see the ASIO4ALL options appear in your system, it is a green square with a white triangle. }); Supercollider computes control functions and other values at a lower rate than the sampling rate called the ``sub-frame'' size. SinOsc.kr(440, 0, 1); By default, control rate ugens generate one sample value for every sixty-four sample values made by an audio rate ugen. If the original tempo is, as above, 86.289 bpm and you want to play at 72 bpm, you have to scale the sample's rate down by a factor of 72 / 86.289 = 0.83440531238049. First Patch 61 8.4. On Fedora Linux, use MIDIFile.sc(installed in /usr/share/SuperCollider/Extensions/MIDIFile/ by Planet CCRMA package supercollider-midifile). Sequencing 4. }).add; The bufnum is the index of the buffer object that we’ll be getting our audio information from. 3. MIDI note numbers are used for these calculations because it's a linear frequency scale and linear interpolation is easier than the exponential interpolation that would be required when using Hz. The video is taken from an atom bomb test video, but slowed down and stretched. Sequence individual loop segments alongside other patterns. Note - no rate control: Hello World 61 8.2. Returns the current sample rate of the server. Indeed, when we write something like SinOsc.ar(440), we are actually creating an object of type SinOsc, and sending to it the value 440 via the method .ar (which stands for “audio rate”), which provides … (The calculations could be structured differently, either putting more of them into the SynthDef for convenience in the pattern, or loading them into the pattern and keeping the SynthDef as lean as possible.). The loop-segment player should provide a rate parameter, where the rate is desiredTempo / originalTempo. . var i = array.indexOfGreaterThan(val); \degree, Pwhite(0, 12, inf), Call a command to fill a buffer. 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 Windows and macOS you can programmatically obtain a list of available audio devices without booting the server:ServerOptions.devices; // all devices scsynth - SuperCollider audio synthesis server SYNOPSIS¶ scsynth [options] DESCRIPTION¶ SuperCollider is a real time audio synthesis programming language.

It might be tempting to loop a PlayBuf so that the loop runs automatically on the server, but it can easily drift out of sync with the client (because of slight deviations in the actual sample rate). This will allow you edit your settings for the application if needed. Passing nil is equivalent to to default:SuperCollider. div = b / a; that can be used to communicate with audio devices. o.outDevice_("Windows WASAPI : Speakers"); Audio is unaffected in other applications prior to opening SuperCollider (e.g., Audacity, Spotify, Facebook, YouTube). SuperCollider access sample rate in a synthdef. * Decay2.kr(Impulse.kr(0), 0.01, 0.05), Since a buffer can be reallocated at any time, using .ir will not track the changes. s.sync; 0. ~midinotes = (39, 46 .. 88); How to send buffer to audio file in Supercollider? If the server fails to boot due to sample rate mismatch, an error will be posted accordingly. Out.ar(out, (sig * env).dup); 0. car = SinOsc.ar(freq + (mod*freq)) * Decay2.kr(initPulse, 0.01, 2.0); Pfindur(4, var start = 0.404561, end = 3.185917, Non-Zero Crossing Edit 52 7.1. To compensate for that, we need a simple math to help us even out the relationship between the sample-rate and the table-size by dividing the table-size with the sample-rate. SuperCollider Quick Reference. mod = SinOsc.ar(freq) * Decay2.kr(initPulse, 0.01, 3) * 5, If you need to use frequency in Hz, use this function in place of indexInBetween.f = { |val, array| Effects 7. Supercollider is a massive software application that would allow you to generate any noise or sound in existence. Pattern Guide Cookbook 05: Using Samples: Playing a pattern in time with a sampled loop, Using audio samples to play pitched material, Pattern Guide Cookbook 06: Phrase Network, /usr/local/share/SuperCollider/HelpSource/Tutorials/A-Practical-Guide/PG_Cookbook05_Using_Samples.schelp. ... with the default tax rate set at 20%. ... sample-rate actual-sample-rate accessors: status-num-ugens status-num-synths status-num-groups status-num-loaded-synths status-avg-cpu status-peak-cpu status-sample-rate \instrument, \bell, An integer representing the nominal sample rate of the server; in other words, the sample rate that was requested of the server when it was booted. // record the samples at different frequencies SuperCollider features three major components: scsynth, a real-time audio server, forms the core of the platform. { ExpRand(400, 1600) } ! When the server is compiled to use JACK as the audio backend, the ServerOption's device can be used in two ways: A nil device is equivalent to Server.default.options.device = "default:SuperCollider"; The JACK connections can be configured via the environment variables SC_JACK_DEFAULT_INPUTS and SC_JACK_DEFAULT_OUTPUTS. ( Third-party extension alert : LoopBuf by Lance Putnam is an alternative - find it in the sc3-plugins package.). ir. It will take care of all the troubles of loading, allocating, measuring, and even beat synchronizing of a small sound file. SuperCollider specifies tempo as beats per second, so we need the reciprocal: 1 / 0.695339 = 1.4381474359988 beats/second (86.289 bpm). \dur, Pwrand(#[0.25, 0.5, 0.75, 1], #[2, 3, 1, 1].normalizeSum, inf) // or, algebraically I’ve got output device sample rate and bit depth set to 24-bit, 48000Hz in Windows control panel. After rebooting the server (Server.default.reboot) you should see in the post window that it now uses the Aggregate Device instead of system defaults: Note that when you specify a sound device through SuperCollider's ServerOptions, there is no need to use the aggregate device as the system's default device. It's no more difficult to play the layers in the independent event stream players, using the quant argument to ensure the proper synchronization. Inherited class methods. rate - 1.0 is the server's sample rate, 2.0 is one octave up, 0.5 is one octave down-1.0 is backwards normal rate ... etc. Partial device name matching is supported in Windows (though not in macOS). ), // record all 8 buffers concurrently Discussion: WARNING: The .ir method is not the safest choice. /b_gen. 6.1. \dur, 1 Class Methods SampleRate. b.do({ |buf, i| 0. ) false (default) -- Use the sample clock. How to send buffer to audio file in Supercollider? ), Inherited class methods. SuperCollider Workshop in Mexico City | Algorithmic and Stochastic Music The 2013 International SuperCollider Symposium, May 20-24, 2013 in Boulder, Colorado USA SC Symposium 2013 Submission Deadline If the original tempo is, as above, 86.289 bpm and you want to play at 72 bpm, you have to scale the sample's rate down by a factor of 72 / 86.289 = 0.83440531238049. rate: rate * BufRateScale.kr(bufnum), Ugens to which a .kr message is appended run at the control rate. This will allow you edit your settings for the application if needed. While synthesis is running, new modules can be created, destroyed and repatched, sample buffers can be created and reallocated. Connectors: RCA, XLR, TRS, TS 54 8.1. inf), b.do(_.free); ~baseBuf.free; Previous: Pattern Guide Cookbook 04: Sending MIDI, Next: Pattern Guide Cookbook 06: Phrase Network. The most recommended APIs are listed first. I’ve got output device sample rate and bit depth set to 24-bit, 48000Hz in Windows control panel. 0. SuperCollider has documentation in the HTML format available in the supercollider … You should set both input and output devices' sample rate to the same value. Supercollider- SynthDef equivalent of using 2 different synths. On Windows there are multiple audio driver APIs (e.g. One possible reason why a server may fail to boot is a mismatch between input and output devices' sample rates, which may occur when using a different device for input and output (which is the case when using a Mac's internal soundcard). The following list provides basic reference for different APIs. I don't think that MSP does this. To compensate for that, we need a simple math to help us even out the relationship between the sample-rate and the table-size by dividing the table-size with the sample-rate. o = OSCFunc({ |msg| 0. "open -a 'Audio MIDI Setup'".unixCmd; // execute this to launch it, Now you need to tell SuperCollider to use your new aggregate device.Server.default.options.device = "Aggregate Device"; //or the name you have specified in the previous step. \dur, Pwrand(#[0.25, 0.5, 0.75, 1], #[2, 3, 1, 1].normalizeSum, inf) 1 ! \accent, Pseq([2, Pn(0, inf)], 1), You can do this in Audio MIDI Setup:"open -a 'Audio MIDI Setup'".unixCmd; // execute this to launch it, Sometimes you might want to use multiple devices for input or output. 1. Before 1 second has passed, our table would have been read almost 48 times, creating 48Hz audio signal instead of 1Hz. There were major fixes and improvements to Quarks between 3.6.x and 3.7, so this will probably be solved by upgrading. It uses one sample, so it would be best for patterns that will play in a narrow range. Tells supernova whether to sync to the driver's sample clock, or to the system clock. b = Buffer.allocConsecutive(~midinotes.size, s, 44100 * 2, 1); Custom UGens are packaged in server plugins. }; What FoxDot brings to the mix is the ability to play live on top of SuperCollider and secondly it's a bit easier to program in. Bij deze waarde geldt over het algemeen, hoe hoger hoe beter. Use a web search engine to find a download link. helpfile source: /usr/local/share/SuperCollider/HelpSource/Classes/SampleRate.schelp link::Classes/SampleRate:: \degree, Pseries(0, Prand(#[-2, -1, 1, 2], inf), inf).fold(-11, 11), Looping point and loop length can be adjusted. TempoClock.tempo = 104/60; SuperCollider is a platform for audio synthesis and algorithmic composition, used by musicians, artists, and researchers working with sound. inf).play(quant: [4, 4]); }; We will use them below. Since there isn't an instrument sample in the SuperCollider distribution, we will record a frequency-modulation sample into a buffer before running the pattern.// make a sound sample } p = Pbind( Connecting multiple stages of parallel synths, with array of buses, in superCollider. (end - start).reciprocal * numBeats I’m sure you will hear the difference when playing back the files. o.free; This question led to a new package: sclang-prettifier I've been poring over the listings manual, trying to figure out how to get some very specific types of formatting for the SuperCollider language..
