Lattice ~ CLI Toolkit For Music Collectors

Posted by tom2tec on

A high-performance CLI toolkit for music collectors who manage their own libraries. Lattice provides a suite of tools for library visualization, integrity verification, cover art extraction, and metadata auditing — all from a single, zero-dependency script.

Why this exists

Modern music players often hide your library behind proprietary databases. Lattice is built for collectors who treat the filesystem as the source of truth. It reads tags directly via mutagen, ensuring your library is portable and player-agnostic.

Features:

ModeFlagDescription
Library Tree--libraryGenerate a formatted ASCII/Unicode tree of your entire collection.
AI Library--ai-libraryToken-efficient export designed for LLM recommendation prompts.
Genre Wings--all-wingsGenerate separate library catalogs segmented by genre.
Integrity Checks--testFLACParallel verification of FLAC/MP3/Opus/WAV integrity via FFmpeg.
Art Extraction--extractArtExtract embedded covers with format-priority ranking (FLAC > Opus).
Tag Audit--auditTagsIdentify and report files with missing or inconsistent metadata.

lowhum ~ Deep Brown Noise For Focus

Posted by tom2tec on

Deep brown noise for focus, for the macOS menu bar. 

Single-purpose menu bar app that generates deep brown noise locally and plays it on loop. Install it, click play, forget about it. Cumulative-sum brown noise through a Butterworth bandpass (1 to 500 Hz, 20 Hz sub-bass highpass), RMS-normalized per chunk, crossfaded at boundaries. Everything is stored in ~/.lowhum/. Playback streams through PortAudio via memory-mapped files, so the full WAV never sits in RAM. The app polls audio devices every 2 seconds and stops instantly if headphones disconnect or a Bluetooth device drops.

Menu bar controls

The menu bar icon is a template image, so macOS handles dark/light mode automatically. Further, use it for:

  • Play / Stop from the menu bar
  • Pick any connected audio device from the Output Device submenu
  • Noise color selection (brown, pink, white)
  • Auto-stops when headphones connect or disconnect

Requires macOS and Python 3.12+.

PedalBoard ~ Python Audio Library

Posted by tom2tec on

pedalboard is a Python library for working with audio: reading, writing, rendering, adding effects, and more. It supports most popular audio file formats and a number of common audio effects out of the box, and also allows the use of VST3® and Audio Unit formats for loading third-party software instruments and effects.

Features:

  • Built-in audio I/O utilities (pedalboard.io)
    • Support for reading and writing AIFF, FLAC, MP3, OGG, and WAV files on all platforms with no dependencies
    • Additional support for reading AAC, AC3, WMA, and other formats depending on platform
    • Support for on-the-fly resampling of audio files and streams with O(1) memory usage
    • Live audio effects via AudioStream
  • Built-in support for a number of basic audio transformations, including:
    • Guitar-style effects: Chorus, Distortion, Phaser, Clipping
    • Loudness and dynamic range effects: Compressor, Gain, Limiter
    • Equalizers and filters: HighpassFilter, LadderFilter, LowpassFilter
    • Spatial effects: Convolution, Delay, Reverb
    • Pitch effects: PitchShift
    • Lossy compression: GSMFullRateCompressor, MP3Compressor
    • Quality reduction: Resample, Bitcrush
  • Supports VST3® instrument and effect plugins on macOS, Windows, and Linux (pedalboard.load_plugin)
  • Supports instrument and effect Audio Units on macOS
  • Strong thread-safety, memory usage, and speed guarantees
    • Releases Python’s Global Interpreter Lock (GIL) to allow use of multiple CPU cores
      • No need to use multiprocessing!
    • Even when only using one thread:
      • Processes audio up to 300x faster than pySoX for single transforms, and 2-5x faster than SoxBindings (via iCorv)
      • Reads audio files up to 4x faster than librosa.load (in many cases)
  • Tested compatibility with TensorFlow – can be used in tf.data pipelines!
