The code for the Sound Generator is based on open-source software and uses retro methods for creating sounds similar to those found in classic games from the 8-bit era.
It's possible to create sounds at https://sfxr.me/ and copy their values into HypeHype. Find a How To Guide on using JSFXR to create custom sounds for the Sound Generator below.
¶ Parameters
| Preview | Preview the sound when editing |
| Enabled | Enable or disable the node. Disabled nodes cannot be executed |
| Looping | Enables sound looping |
| 3D | If enabled, position relative to camera affects the sound |
| Allow Override | If enabled, sending signal to 'Enabled' can re-trigger the sound while playing |
| 8 bit | If enabled, the sound is grittier |
| Volume | Sound volume level (0 - 1) |
| Reverb Amount | How much sound is sent to reverb effect (0 - 1, does nothing if there are no reverbs) |
| Distance Function | Formula used to determine the volume based on the proximity to the camera when 3D is on. |
| Inner Distance | The maximum distance from the camera to which this Node will play at the specified Volume when 3D is on. |
| Max Distance | The minimum distance from the camera to which this Node will play at 0 volume when 3D is on. |
| Pitch | Pitch multiplier (-5 - 5, 0 = nominal pitch, 1 = one octave up etc) |
| Length | Length in seconds; can be used to cut the sample's end (0 = no cutting) |
| Wave Type | Waveform shape: Square, Sawtooth, Sine, Noise |
| Attack Time | Volume envelope attack length (0 - 1) |
| Sustain Time | Volume envelope sustain length (0 - 1) |
| Sustain Punch | Short volume boost at the sustain beginning amount (0 - 1) |
| Decay Time | Volume envelope decay length (0 - 1) |
| Start Freq | Sound starting frequency (0 - 1) |
| Freq Limit | The sound will stop if the frequency goes below this threshold (0 - 1, 0 = disabled) |
| Freq Ramp | Sound frequency change speed (-1 - 1) |
| Freq Delta Ramp | Sound frequency change acceleration (-1 - 1) |
| Vibrato Depth | Depth of vibrato effect (0 - 1) |
| Vibrato Speed | Speed of vibrato effect (0 - 1) |
| Arp Mod | Frequency change after a delay (-1 - 1) |
| Arp Speed | Delay of the frequency change (0 - 1) |
| Duty | Only applies to Square Wave Type; controls the pulse width (0 - 1) |
| Duty Ramp | Pulse width change speed (-1 - 1) |
| Retrigger | Delay before the sound is retriggered (0 - 1, 0 = disabled) |
| Flanger Offset | Flanger effect depth (-1 - 1) |
| Flanger Ramp | Flanger effect depth change speed (-1 - 1) |
| Low-pass Freq | Low-pass filter frequency (0 - 1) |
| Low-pass Freq Sweep | Low-pass filter frequency change speed (-1 - 1) |
| Low-pass Q | Low-pass filter resonance amount (0 - 1) |
| High-pass Freq | High-pass filter frequency (0 - 1) |
| High-pass Sweep | High-pass filter frequency change speed (-1 - 1) |
| Gain | Sound generation volume (0 - 1, high levels can distort the sound) |
¶ Using JSFXR to Create Custom Sounds
The web resource JSFXR can be used to create custom sound effects for the Sound Generator.
- Visit https://sfxr.me/
- Use the provided presets and tools to create the desired sound
- Select the "Serialize" button to expose the values for that sound
- Copy the values from JSFXR into the Sound Generator Node
Use the diagram below if you need help translating the JSFXR values into the Sound Generator
