lowhum ~ Deep Brown Noise For Focus


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+.

AudioPlayer ~ CD Image Player


This is an audio player for Windows, Linux and MacOS.

It is designed to play audio CDs dumped to raw bin/cue files.

The bin/cue files can be loaded from a folder on disk, or from a zip archive.

This player provides a convenient way of listening to dumps in that format without any additional step(s):

  • No need to mount the cue file as a virtual drive.
  • No need to extract the cue/bin files from zip files.
  • No need to convert the data to wav/flac/ogg/mp3.

This is currently NOT supported:

  • Playing from archives in 7z and rar formats.
  • Playing music from other formats such as wav, mp3, flac, ogg, etc. Just use a regular music player for that.

Album and track metadata is loaded from the CDTEXT information when present in cue file.

Additional metadata is optionally retrieved from CueToolsDB, including album art.

Lyrics are optionally retrieved from LRCLIB. Using a local LRCLIB sqlite3 database is also supported.

foo_scrobbler_mac ~ Foo Scrobbler For Macs


Foo Scrobbler (foo_scrobbler_mac) is a native Last.fm scrobbling plugin for foobar2000 on macOS. Submits tracks based on precise playback rules, caches scrobbles when offline, and operates silently after one-time authentication. Built using the official foobar2000 plugin API, it focuses on reliability, low overhead, and correct metadata handling. Fully open-source under GPLv3.

Supports macOS ≥ 11.5 on both Intel and ARM.

caudec ~ Multiprocess Audio Converter


caudec is a command-line utility that transcodes (converts) audio files from one format (codec) to another, among other things.

It leverages multi-core CPUs and runs multiple processes concurrently (one per file and per codec, and more than one thread per codec when it supports it). The objective is to hog the CPU as much and as long as possible. One strategy is to sort input files by size, so that the largest files potentially get more threads towards the end of the job.

Features:

  • Supported input formats / codecs: WAV, AIFF, CAF, FLAC, WavPack, Monkey’s Audio, ALAC.
  • Supported output formats / codecs: all of the above, as well as LossyWAV / LossyFLAC, MP3, AAC (.m4a), Ogg Vorbis, Opus.
  • Supported platforms: macOS, Linux.
  • Transcoding to several different codecs at once is possible. In that case, decoding of input files is done only once.
  • Metadata is preserved (as much as possible) from one codec to another.
  • Artwork can be embedded into each file, and / or copied to the output directory. It can be done selectively (e.g. embed and / or copy one image for lossless files, and another image for lossy files).
  • Audio can be resampled (e.g. 48kHz to 44.1kHz) and downmixed (e.g. 6 channels to stereo). A profile can be provided to set a maximum value for the number of channels, bit depth and sampling rate. When a profile is provided, the source will only be altered after decoding and before encoding, if some metric of the source is above the given profile.
  • Multiprocess ReplayGain scanner for FLAC, WavPack, MP3, Ogg Vorbis, Opus.
  • Ability to hard link lossy files to a different directory when encoding to WavPack Hybrid. The point is to have two libraries that takes the storage of just one, with a lossy collection that has its own root directory and that’s easy to drag and drop to a device such as a smartphone or a Digital Audio Player (DAP).
  • Ability to touch files and album directories using metadata to reflect the music’s release date and duration (see example below).
