Dancing QT is a combined music database and player application specially designed for dancing schools and equivalent applications. Key features are an easy-to-use interface, fast search capabilities, playlist management, exact pitching and crossfading.
Looking around the open source landscape for a while, I tried to find a music database and player that is suitable for use in a dancing school environment – without success. Most mixing applications tend to be too confusing for the intended audience, most players lack database searching capabilites and most song databases don’t know how to pitch 😦
Because of this, I decided to setup a new application – Dancing QT. It uses alsaplayer because of its excellent interface and pitching capabilities, it uses an embedded SQLite DBMS to maintain a song database, and it uses taglib to populate the database. The interface is written in C++ using Qt. Because of the alsaplayer dependency, the target platforms will be limited to environments providing alsaplayer.
QPxTool is the Linux way to get full control over your CD/DVD drives. It is the Open Source Solution which intends to give you access to all available Quality Checks (Q-Checks) on written and blank media, that are available for your drive. This will help you to find the right media and the optimized writing speed for your hardware, which will increase the chance for a long data lifetime. See supported devices to get a list of the currently supported hardware.

This program makes a linux computer equipped with a modern sound card behave as a traditional hi-fi preamp, but able also to make advanced DSP equalization and crossover tasks.
That means that, with a proper soundcard, external sources can be used, be them analog or digital, along with digital libraries or streamed sources.
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.
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.
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).
