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.

shntool ~ WAVE Processing & Reporting Utility


shntool is a multi-purpose WAVE data processing and reporting utility. File formats are abstracted from its core, so it can process any file that contains WAVE data, compressed or not – provided there exists a format module to handle that particular file type.

shntool has native support for .wav files. If you want it to work with other lossless audio formats, you must have the appropriate helper program installed. The “Helper programs” section below contains links to helper programs for each format that shntool supports.
