4 bit quantized triangle wave, no anti-aliasing Sample 2Īudio tag not supported. One period triangle waveform output of FamiTracker Sample 1Īudio tag not supported. The triangle wave normally contains only odd harmonics, but this irregularity causes the signal to gain even harmonics, characteristic of the saw wave.
The falling segment of the waveform is slightly curved and the rise is linear. It also has an asymmetrical rise and fall. It is produced by quantizing a triangle waveform to 16 discrete amplitudes. The Nintendo triangle wave has a distinct sound.

Notice the first tone produces undesirable full bandwidth clicks when the pulse width changes. The third tone is the corrected full-bandwidth square wave produced by SynthMaker. The second and fourth tones are produced by FamiTracker. The first tone is produced by SynthMaker before correction. The results are compared here:Īudio tag not supported. The test signal was a square wave with pulse width modulation cycling across 25%, 50%, 75%, and 12.5% pulse width. This was unsatisfactory and we switched to a construction from saw waves limited at nyquist. Our square wave was initially constructed by summing two saw waves limited at half bandwidth, which really means 1/4 of the sample rate or 11,025 hz. The following is a discussion of each 2A03 chip sound channel (Square, Triangle, Noise, and DPCM) and their implementation in SynthMaker. In our project, aliasing is minimized with conventional techniques available in SynthMaker. The plugin was built in Outsim SynthMaker to allow for an advanced user interface, and sounds were evaluated against the output of FamiTracker, which uses the Blip Buffer library to generate "perfect" alias-free primitive waveforms. The NES VST is designed to emulate the 8-bit sounds of the Nintendo, remaining faithful to the specifications of the 2A03 chip. Steps Ahead Project Notes and Documentation

You won't find these tunes on Spotify 🙂 Download NES VST 1.2 If you use my VST in your project, give me a shout on Twitter inspired! My latest project is Chip Player JS.
