Sonic Topography is a desktop music player and 3D music visualization application. It transforms the low, mid, and high frequencies in music into three-dimensional terrain that undulates, glows, and flashes, turning listening to music into a breathing sound map.

The workflow is Ableton Live’s: a grid of clips you launch against a global tempo grid, quantised to musical boundaries. The architecture is not Live’s, and that is the point.
Your set is text
A project is one line-oriented plain-text file with a byte-identical round-trip and stable per-entity uids. A melody is eight
note <beat> <len> <pitch> <vel>lines. Diff a mix, branch an arrangement, review a track in a pull request, generate a set from a script.The audio thread shares nothing
No allocation, no locks, no pointers into GUI memory: the interface reaches the engine through a lock-free command ring and a block of atomics. Launches are split inside the buffer, so a clip starts on the exact frame of its quantum rather than at the top of the next block.
nxtaktdalready runs that engine as its own process, playing clips out of a shared-memory sample pool.CI plays what it builds
Every push builds the whole application, runs the headless suite — 2,500+ assertions across the engine, the IPC layer, the daemon and the devices — and then renders five passes of the demo set to FLAC, printing the peak and RMS of each into the run summary. The pipeline does not just compile this DAW. It hands you the audio.
Native VST3 audio effects for OBS Studio on Windows — isolated plug-in hosting, vendor GUIs, automatic discovery, state restore and dry fail-open recovery.
Why this project exists
OBS Studio’s built-in VST filter does not provide VST3 hosting. Many current studio EQs, compressors, restoration tools, reverbs, saturators, limiters and mastering processors are distributed primarily, or only, as VST3s.
OBS Safe VST3 Host adds two OBS-native workflows on Windows:
- VST 3.x Plug-in — a simple one-effect filter for the common case.
- VST3 Rack — a separate isolated serial multi-effect chain with a dedicated graphical Rack Editor and broadcast-oriented master console.
Third-party VST3 runtime code, vendor editors and plug-in scanning are deliberately kept outside the OBS process.
RackForge is a cross-platform instrument and live-performance host. Connect a MIDI keyboard, choose an instrument, combine sounds into Racks, organize a show into Songs and Setlists, and play without building a DAW session first.
RackForge uses the same musical model on Windows, Linux, Android, and Raspberry Pi. Portable
.rfplugininstruments bring their sound and interface with them, while RackForge owns the audio, MIDI, routing, presets, and live performance workflow.RackForge
v0.1.xis a public preview. It is ready to explore and play, but native packages are not yet production-signed.

A pure-Python inspector, editor, and forensic tool for audio files and synth/DAW presets: read the metadata, decode the format structure byte by byte, flag anomalies, repair broken containers, and identify how a file was made.
Reads BPM, key, duration, tags, and format info from WAV, AIFF, MP3, FLAC, OGG, Opus, M4A, MIDI, and Serum presets. Also structurally decodes Bitwig (.bwpreset/.bwclip), Native Instruments (Massive/Absynth/Kontakt/NKS/KORE), Vital, NCW, SoundFont (SF2/SF3), tracker modules (MOD/XM/IT), MP4, VST FXP, ReCycle RX2, and RMID containers via
inspect. Beyond reading:repairandvalidatefix and check container structure (stale sizes, offset tables, counts, pad bytes) without touching a byte of audio, andauditgives a forensic verdict (structure, integrity, hidden data, and the writing tool). One pure-Python dependency (mutagen); the nativeinspectwalkers need nothing. Optional librosa analysis for BPM/key detection and ML feature extraction.Also ships per-library SQLite indexes (
acidcat index) tracked in a small global registry, plus an MCP server (acidcat-mcp) so an LLM can query your whole collection across libraries by bpm, key, tags, or full-text.
