Introduced by Ville-Matias Heikkilä (viznut) in 2011, bytebeat generates PCM audio data using a single loop. The most common formula looks like this in C or JavaScript: javascript
(wave1 + wave2) >> 1 (safely halves the volume to prevent digital distortion).
No DAW. No VSTs. Just pure arithmetic and note data.
Thus, converting MIDI to Bytebeat means encoding pitch, duration, and amplitude information from discrete events into a single mathematical function f(t) that generates the audio in real time.

MIDI is linear. ByteBeat is parallel. Bridging them creates a weird, wonderful hybrid — part composition, part raw mathematics.
: Convert durations into bytebeat time chunks (e.g., one sixteenth note = 1024 ticks of t ).

To play a specific MIDI note, you must convert its MIDI number ( ) into a frequency ( No VSTs
There are two primary methods for converting a MIDI file into a bytebeat formula. Approach A: The Compressed Data Array (Recommended)
Because Bytebeat cannot have conditionals that depend on a sequencer's state (unless you hardcode timing), the conversion process usually involves or generating a massive polynomial that encodes note durations.
In the MIDI standard, Middle C (C4) is assigned the number 60. The actual frequency ( ) in Hertz is derived using the formula:
Factor=440×2568000≈14.08Factor equals the fraction with numerator 440 cross 256 and denominator 8000 end-fraction is approximately equal to 14.08 This public link is valid for 7 days
) are inefficient. Instead, programmers use fixed-point math by shifting the values left (multiplying by a power of 2):
// A classic viznut formula (t * 5 & t >> 7) | t * 3 & t >> 10 Use code with caution.
: Bytebeat is a form of algorithmic music where audio is generated by a single line of code—typically a formula involving a time variable
Bytebeat formulas are single expressions. To play a sequence of notes, you must partition the time axis. The simplest method: .
Once the sequence array is ready, it is injected into a structural template. Below is an example of a JavaScript-based Bytebeat template generated by a MIDI converter for a single-track melody: javascript
