The Sound Description Interchange Format (SDIF) is an established standard for the interchange of sound descriptions and analysis data. This project provides libraries, SDIF (in C) and Easdif (in C++), tools, and wrappers to read and write SDIF files.

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.
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.
| Mode | Flag | Description |
|---|---|---|
| Library Tree | --library | Generate a formatted ASCII/Unicode tree of your entire collection. |
| AI Library | --ai-library | Token-efficient export designed for LLM recommendation prompts. |
| Genre Wings | --all-wings | Generate separate library catalogs segmented by genre. |
| Integrity Checks | --testFLAC | Parallel verification of FLAC/MP3/Opus/WAV integrity via FFmpeg. |
| Art Extraction | --extractArt | Extract embedded covers with format-priority ranking (FLAC > Opus). |
| Tag Audit | --auditTags | Identify and report files with missing or inconsistent metadata. |

Bitfake was originally created to detect fake
.FLACfiles through spectral analysis. It has since grown into a multipurpose CLI tool for handling music more easily and efficiently.One common problem was that getting a track’s metadata required long
ffprobecommands with messy output. Converting music withffmpegwas also repetitive. The command itself is easy to remember, but writing scripts to convert entire directories felt inefficient and slow. This project now performs metadata and conversion tasks directly through linked libraries (TagLib/libsndfile/libav*).

Further development of the ASIO output module by otachan (2006) for the Winamp player, including:
- problem with setting the sample rate fixed
- gapless mode completed
- added individual channel assignment
- added upsampling to a non-fractional multiple of base-frequency
- added high quality resampler: sample rate doubler for best audio playback

A music player for your local music library.
- Linux first
- Local only: no internet connection will ever be established.
- Read only: your music will be accessed only in read mode.
- Stateless: no cache/database/whatever will be created. The metadata in your songs are the database.
- Imperfect: there will be use-cases that are not solved by this software, and that’s fine.

FlavourMTC follows classic “passive” equalizer designs where the EQ circuits itself are not able to amplify signals but a dedicated amplifier stage takes care of it. Those EQ designs are well known for allowing very transparent frequency changes while their amplifier designs do add some icing on the cake quite often.
FlavourMTC implements this by utilizing 1st order shelving filter designs avoiding unwanted resonances and takes advantage of “zero delay” implementations for most accurate higher order filtering and w/o introducing curve warping near Nyquist frequency. The output amplifier stage of the plugin can be calibrated according specific mixing levels, provides a distinct “box tone” and glues everything together. Parts of the plugin are oversampled internally for maximum transparency and sound quality.
