If t is time, a standard sawtooth wave is simply t . To pitch it up, we bitshift right: t >> n .
Automation parameters like volume, panning, or modulation. What is Bytebeat?
Create a decaying volume envelope for notes by multiplying the voice by a downward ramp generated from the timer: * (32 - ((t >> 8) & 31)) .
Musical Instrument Digital Interface (MIDI) and Bytebeat represent two completely opposite philosophies in computer music. MIDI is a symbolic, descriptive protocol that tells an instrument how to play a note. Bytebeat is a functional, generative method where a single line of mathematical code directly outputs raw audio bytes.
def midi_to_bytebeat_array(midi_file, sample_rate=44100): mid = mido.MidiFile(midi_file) ticks_per_beat = mid.ticks_per_beat total_samples = int(mid.length * sample_rate) output = np.zeros(total_samples, dtype=np.uint8) midi to bytebeat
, usually 8000Hz or 11025Hz for that authentic lo-fi grit), a step size of per sample ( ) creates a base frequency. To play a specific frequency , we replace the steadily incrementing
Unlike standard MIDI-to-audio conversion in professional software like Reaper or Ableton , bytebeat conversion intentionally introduces aliasing and quantization noise, making it a favorite for "gorenoise" and experimental electronic genres. 4. Conclusion
By mapping MIDI to Bytebeat, you create an instrument that sounds like no other. It is not a clean synthesizer; it is a chaotic signal processor.
This value is sent directly to the audio output as a waveform sample. If t is time, a standard sawtooth wave is simply t
You can use the modulo operator ( % ) and bit shifts to sequence notes: (t >> 10) & 15 creates a repeating 16-step sequencer loop.

freq = [261, 293, 329, 349]; note = freq[int(t/8000)%4]; sin(2 * PI * t * note / 8000) * 127 + 127
Converting MIDI to bytebeat is the process of translating messages—which include information on pitch, velocity, and timing—into these mathematical formulas. 1. The Challenge of Translation What is Bytebeat
