Add faust-create-faustnode.js test to demonstrate the new createFaustNode higher-level API

[sletz]

Changes here :

• examples/faust.js renamed to examples/faust-osc.js for more consistency

• new examples/faust-create-faustnode.js to demonstrate the use of the createFaustNote (just added this morning in faustwasm 0.13.0 package) which simplifies creating monophonic (synthesiser and effects) or polyphonic (MIDI controllable instruments). Several Faust DSP programs added to show different use-cases.

Hey, I get some audio output working but I also get this error when running the example, e.g.:

Error: ScriptProcessor_poly_effect_test:8 : ERROR : undefined symbol : effect

    at _FaustCompiler.createDSPFactory (file:///.../letz-node-web-audio-api/node_modules/@grame/faustwasm/dist/esm/index.js:1411:36)
    at async _FaustPolyDspGenerator.compile (file:///.../letz-node-web-audio-api/node_modules/@grame/faustwasm/dist/esm/index.js:5491:28)
    at async _FaustDspGenerator.createFaustNode (file:///.../letz-node-web-audio-api/node_modules/@grame/faustwasm/dist/esm/index.js:5876:30)
    at async runPolyEffectTest (file:///.../letz-node-web-audio-api/examples/faust-create-faustnode.js:150:18)
    at async main (file:///.../letz-node-web-audio-api/examples/faust-create-faustnode.js:201:3)
    at async file:///.../letz-node-web-audio-api/examples/faust-create-faustnode.js:205:3

This seems to affect the poly_test and poly_effect_test, with both AudioWorklet and ScriptProcessor i.e.:

Error: AudioWorklet_poly_test:11 : ERROR : undefined symbol : effect
Error: AudioWorklet_poly_effect_test:8 : ERROR : undefined symbol : effect
Error: ScriptProcessor_poly_test:11 : ERROR : undefined symbol : effect
Error: ScriptProcessor_poly_effect_test:8 : ERROR : undefined symbol : effect

Am I missing something?

[sletz]

Well, this is not really an error: it happens when compiling a polyphonic code without effect (the first one here: https://github.com/sletz/node-web-audio-api/blob/e4d8cd8b6dd014a86927ba588c59ae410d69a7c7/examples/faust-create-faustnode.js#L41). The second one https://github.com/sletz/node-web-audio-api/blob/e4d8cd8b6dd014a86927ba588c59ae410d69a7c7/examples/faust-create-faustnode.js#L50 has an effect and compiles normally. As this acceptable or should I try to improve the user feedback here ?

[sletz]

@b-ma wait a bit, I'll improve all that.

New commit to solve the issues.

Cool, thanks
