The examples fall into +several categories: + +1. Effects which can be used as reusable building blocks (named + effect_*.arts) + +2. Standalone examples illustrating how to use each of the built-in + arts modules (named example_*.arts). These typically send some + output to a sound card. + +3. Instruments built from lower level arts modules (named + instrument_*.arts). These following a standard convention for + input and output ports so they can be used by a (future) instrument + manager. + +4. Mixer elements used for creating mixers, including graphical + controls (named mixer_element_*.arts). + +5. Templates for creating new modules (names template_*.arts). + +6. Miscellaneous modules that don't fit into any of the above + categories. + +Detailed Description Of Each Module +----------------------------------- + +Examples +-------- + +example_stereo_beep.arts + +Generates a 440Hz sine wave tone in the left channel and an 880Hz sine +wave tone in the right channel, and sends it to the sound card +output. This is referenced in the aRts documentation. + +example_sine.arts + +Generates a 440 Hz sine wave. + +example_pulse.arts + +Generates a 440 Hz pulse wave with a 20% duty cycle. + +example_softsaw.arts + +Generates a 440 Hz sawtooth wave. + +example_square.arts + +Generates a 440 Hz square wave. + +example_tri.arts + +Generates a 440 Hz triangle wave. + +example_noise.arts + +Generates white noise. + +example_dtmf1.arts + +Generates a dual tone by producing 697 and 1209 Hz sine waves, scaling +them by 0.5, and adding them together. This is the DTMF tone for the +digit "1" on a telephone keypad. + +example_atan_saturate.arts + +Runs a triangle wave through the atan saturate filter. + +example_autopanner.arts + +Uses an autopanner to pan a 400 Hz sine wave between the left and +right speakers at a 2 Hz rate. + +example_brickwall.arts + +Scales a sine wave by a factor of 5 and then runs it through a +brickwall limiter. + +example_bus.arts + +Downlinks from a bus called "Bus" and uplinks to the bus +"out_soundcard" with the left and right channels reversed. + +example_cdelay.arts + +Downlinks from a bus called "Delay", uplinks the right channel through +a 0.5 second cdelay, and the left channel unchanged. You can use +artscontrol to connect the effect to a sound player and observe the +results. + +example_delay.arts + +This is the same as example_cdelay but used the delay effect. + +example_capture_wav.arts + +This uses the Synth_CAPTURE_WAV to save a 400 Hz sine wave as a wav +file. Run the module for a few seconds, and then examine the file +created in /tmp. You can play the file with a player such as kaiman. + +example_data.arts + +This uses the Data module to generate a constant stream of the value +"3" and sends it to a Debug module to periodically display it. It +also contains a Nil module, illustrating how it can be used to +do nothing at all. + +example_adsr.arts + +Shows how to create a simple instrument sound using the Envelope Adsr +module, repetitively triggered by a square wave. + +example_fm.arts + +This uses the FM Source module to generate a 440 Hz sine +wave which is frequency modulated at a 5 Hz rate. + +example_freeverb.arts + +This connects the Freeverb effect from a bus downlink to a bus +outlink. You can use artscontrol to connect the effect to a sound +player and observe the results. + +example_flanger.arts + +This implements a simple flanger effect (it doesn't appear +to work yet, though). + +example_moog.arts + +This structure combines the two channels from a bus into +one, passes it though the Moog VCF filter, and sends +it out the out_soundcard bus. + +example_pitch_shift.arts + +This structure passes the left channel of sound card data through the +Pitch Shift effect. Adjust the speed parameter to vary the effect. + +example_rc.arts + +This structure passes a white noise generator though an RC filter and +out to the sound card. By viewing the FFT Scope display in artscontrol +you can see how this varies from an unfiltered noise waveform. + +example_sequence.arts + +This demonstrates the Sequence module by playing a sequence of notes. + +example_shelve_cutoff.arts + +This structure passes a white noise generator though a Shelve Cutoff +filter and out to the sound card. By viewing the FFT Scope display in +artscontrol you can see how this varies from an unfiltered noise +waveform. + +example_equalizer.arts + +This demonstrates the Std_Equalizer module. It boosts the low and high +frequencies by 6 dB. + +example_tremolo.arts + +This demonstrates the Tremolo effect. It modulates the left and right +channels using a 10 Hz tremolo. + +example_xfade.arts + +This example mixes 440 and 880 Hz sine waves using a cross fader. +Adjust the value of the cross fader's percentage input from -1 to 1 to +control the mixing of the two signals. + +example_pscale.arts + +This illustrates the Pscale module (I'm not sure if this is a +meaningful example). + +example_play_wav.arts + +This illustrates the Play Wave module. You will need to +enter the full path to a .wav file as the filename +parameter. + +example_multi_add.arts + +This shows the Multi Add module which accepts any number of inputs. It +sums three Data modules which produce inputs of 1, 2, and 3, and +displays the result 6. + +Instruments +----------- + +instrument_flexible_slide.arts + +instrument_flexible_slide_GUI.arts + +instrument_fm_horn.arts + +instrument_full_square.arts + +instrument_moog_vcf_tune.arts + +instrument_moog_vcf_tune_GUI.arts + +instrument_neworgan.arts + +instrument_nokind.arts + +instrument_organ2.arts + +instrument_simple_sin.arts + +instrument_simple_square.arts + +instrument_simple_tri.arts + +instrument_slide.arts + +instrument_slide1.arts + +instrument_square.arts + +instrument_tri.arts + +Effects +------- + +effect_delay.arts + +effect_delay_alone.arts + +effect_flanger_alone.arts + +Templates +--------- + +template_Empty_Structure.arts + +template_Instrument.arts + +template_Instrument_GUI.arts + +template_Mixer_Element.arts + +Mixer Elements +-------------- + +mixer_element_simple.arts + +mixer_element_eq.arts + +mixer_element_eqfx.arts |
