ZzFX - Major update/rewrite

ZzFX Features

• Micro synth engine with 9 controllable parameters.
• Tiny code footprint (<1k) for the minified version.
• Smaller ZzFXmicro version provided without seeds.
• Can produce a wide variety of sound effect types.
• Seeded sounds can be played with a tiny function call, ex: ZZFX.z(3)
• Seeded sound paramerters can be overridden.

ZzFX UI Features

• Generate random sounds from seed.
• Stores sounds in list with local storage persistence.
• Parameters can be modified for more control.
• Lock, reset and mutate buttons for each parameter.
• Sounds can be download as a wave file.

Additional notes...

• You can use ZZFX.R() as a random number generator.
• Try playing multiple sounds simultaneously for unique effects.
• You can change the master volume and frequency randomness.
• Feel free to modify any or all of this code!

Here's the latest version of the ZzFXmicro you can use directly!

Seed sound generation improvements

v1.02

Seed generation tweaks

Improved sound generation from seed.

v1.01

Small update - increase modulation frequency range

ZzFX - Original 1k Version

Original 1k version of ZzFX, made for js1k.

ZzFX Features

• Micro synth engine with 6 controllable parameters, you can add more.
• Seeded sounds can also be played using as few as 4 bytes, ex: z(3)
• Able to produce a wide variety of sound effect types.
• Tiny footprint, after being minified with closure ZzFX lib is 373 bytes.
• Compresses well with JSCrush (alongside the rest of your game)
• You can include just the Z function by itself if you don't want seeds.

ZzFX UI Features

• This entry is mostly just a wrapper around ZzFX.
• When the page loads it is filled with cards each corresponding to a seed.
• Just click on a card to play the sound for that seed.
• Each card also has a unique visual apearance tied to that seed.
• You can click on the ZzFX logo to copy the last played seed or change it!
• There is a section in code to set up a preset custom card layout.

Additional notes...

• Be careful of variable name collisions! vars used are ZzFfXRr, don't use them.
• If you use closure compiler, it will shorten the internal variable names.
• You can use R() instead of Math.Random() to save space.
• Feel free to completely modify any of this code!
• Try playing multiple sounds at once for unique effects.
• You can also use negative seeds.
• Try using any repeated numbers in your code as seeds, maybe you'll get lucky.
• There is built in 5% frequency randomness in z(), you can change it.
• You can also add parameters to z(), like a float to scale volume by, etc.
