## What is Raw Byte Audio Machine?

The Raw Byte Audio Machine allows the user to operate on a constant sawtooth wave that is calculated against the assigned sample rate and bit-depth. With each sample, the counter "t" increments by 1. Your expression is evaluated and the lowest bits become a PCM audio sample. Expressions allow for binary arithmetic like addition, subtraction, division, and modulo; and bitwise operations like AND/OR/NOT and bit shifting. With these combinations of tools, a single expression can yield tremendous musical results in complex rhythms, harmonies, and melodies, all while operating on a single sawtooth wave. Operates as a standalone app or AUv3 instrument plugin.

## Key features

- Sawtooth wave synthesis
- Expression engine for sound design
- Binary and bitwise operations
- Rhythm, harmony, and melody generation
- Standalone app
- AUv3 instrument plugin

## Version history (last 5 releases)

### 1.1.3 — 2026-06-02

- Added oscilloscope to AUv3 version
- Fixed interleaved audio bug

### 1.1.2 — 2026-05-26

- Keyboard size allows for better viewing in landscape mode
- Toggle between raw and alpha keyboard for entering comments without Bluetooth keyboard

### 1.1.1 — 2026-05-22

- AUv3 text box state saves expression when saving host app session
- Bluetooth/remote keyboard input
- Arrow navigation in text box without forcing deletes
- Blinking cursor for text input position clarity
- Commenting at the end of expression is allowed with //

### 1.1 — 2026-05-19

AUv3 instrument compatibility added!

- The AUv3 plugin runs at the host's sample rate (typically 44.1 or 48kHz) while keeping t advancing at a fixed 8kHz internally.
- The standalone runs the engine at its selected sample rate (8kHz by default) and lets iOS upsample to the device's hardware rate.
- Both are mathematically valid renderings of the same signal: a deterministic integer sequence produced at 8kHz. The standalone is that sequence after additional iOS filtering; the AUv3 is that sequence reconstructed with minimal coloration. The AUv3 will sound slightly brighter and crisper as a result.

### 1.0 — 2026-05-12

No release notes.
