Muine is an innovative music player, featuring a simple, intuitive interface. It is designed to allow users to easily construct a playlist from albums and/or single songs. Its goal is to be simply a music player, not to become a robust music management application. This doesn’t mean Muine has no features! Some feature highlights:
Muine is targeted at the GNOME desktop and uses GTK+ for the interface. Most of the code is written in C#, with some additions/bindings/glue in plain C. Muine was originally written by Jorn Baayen, but now maintained mostly by others.

Pine Player is an exclusive listening digital music player for music lovers who use the OSX operating system. It can play almost all existing digital audio forms such as MP3, FLAC, APE, AAC, M4A, WAV, AIFF, OGG, WMA, DSD, SACD ISO etc. and it also has a strong playing capability for listening to CUE files in the most convenient way.
1. Maximum 32Bit 768kHz Up Sampling Function
Pine Player supports various kinds of PCM formats, so it can play sound sources from 16 to 32 bit; it can also reproduce clear and abundant sound quality by supporting a maximum of 768kHz.
Pine Player’s unique Over Sampling Filter is a technique that upconverts an ordinary MP3 file into a 32bit, maximum of 768kHz, and high sound quality sound source and sends it to the DAC for it to be played in best performance. Ordinary MP3 files’ sound quality can actually be heard more clearly and plentifully. Obviously, HD audio files such as MQS and DSD can be upconverted to a maximum of 768kHz as well.
2. Convenient and Strong Playlist & Prevention of Text Cracking
Pine Player has a very convenient playlist because users can save and manage the music they wish to listen to, change the order of the music being played by simply dragging, and express any kind of language or text encoding perfectly because of its flawless decoding function. There is no Korean code cracking.
3. Cross Fade and Gapless set-up
Cross Fade function, which is a technique that decreases the gap between songs when listening to files on the playlist or overlaps the songs for no gaps at all, can be set into seconds.
4. Mass Storage of Audio Queue for Real Time Converting
Pine Player prevents damage of sound quality by having a high-powered Audio Queue for processing excessive amount of digital data. Therefore, it takes a considerable amount of memory compared to other music players.
5. Automatic Isolation of Damaged Sound Sources
Pine Player has an automatic isolation function for damaged sound sources called Vault. If a damaged sound source is detected while playing the music, the music is stopped and taken to the Vault file for isolation. Through this convenient function, users can easily figure out which sound source is damaged and restore it.
Even with all these functions, Pine Player is a free app. Moreover, there are not any marketing or advertising material. Especially, no information including personal ones are sent to the outside or the Internet.

The Daphile is the heart of a digital music system. Its primary focus is in storage and playback of your digital music library. It enables the best possible audio quality and future-proof flexibility by providing plug&play support for USB connected digital-to-analog converters (DAC). You can easily setup a multi-zone system just by connecting another USB DAC for each zone.
Daphile is based on the open source Squeezebox Server, Squeezelite and Linux.
Since Daphile is used and configured completely via the web interface the user is not required to have any Linux skills.

DSF_FillMute is a program that replaces a series of trailing zeros created by the standard of DSF files with a silent signal (0x69,1001 0110b). It is effective for devices that generate noise by playing a series of trailing zeros. There is no change in the actual sound or ID3 tag because no processing is added except at the end.
PCM-DSD Converter is a program that converts a PCM WAV format sound source to DSD DSDIFF format. You can convert from PCM 16bit ~ 64bit Float / 44.1 ~ 768kHz to DSD16-DSD2048.
Adds and fixes music metadata and adds album art.
