The stock music player on my phone needed unnecessary permissions! So, I created one on my own 😀

mp3menu lets you select and play your music files using iselect and AlsaPlayer. Mainly MP3’s, but this will actually play anything AlsaPlayer and libaudio can handle, so WAV and FLAC are covered, as well as a bunch of ancient formats dating back to the 1980s. Sadly, M4A is not.
Requires:
1. AlsaPlayer
2. Iselect
3. Bash – mp3menu is a bash script. It might work with zsh, dash and other shells, or it might not.

WildMIDI is a simple software MIDI player which has a core software synthesizer (softsynth) library that can be used with other applications.

A graphical (Qt5) client for MPD, supporting the following features:

This is a React Native-based audio streaming app for Jellyfin. Jellyfin is a community-based piece of software that allows you to stream your media library over the internet. By means of React Native, Jellyfin Audio Player allows you to stream your Jellyfin Music library, with full support for background audio and casting (ie. Airplay and Chromecast).

RaspyFi is an open source linux distribution. It will transform your Raspberry Pi into an audiophile source, in 10 minutes without hassles. It comes ready to play, and it’s compatible with almost every USB DAC available. You can consider it as a Voyage-MPD version for Raspberry Pi. But it’s simpler to use and it has several other functionalities!
With RaspyFi you’ll be able to play your music library directly from an USB Storage or from your NAS. You can also listen to your favourite web-radios and scrobble your favourite tunes from Spotify, Last.fm and Soundcloud. You will be amazed about the sound quality! RaspyFi’s core feature is this. We are trying to get every bit of your music to play as accurate as can be, optimizing every aspect of the system.
RaspyFi supports asynchronous playback to take advantage of the latest DACS, it features a nice webgui you can use to configure it without hassles and to play your library from your pc, your smartphone or your tablet.
You can connect your little Raspberry Pi to your Audio System, sit on your couch, use your favourite device (Win,Mac,Android,iOS) as a remote control and enjoy your music as it is. With RaspyFi your Pi never sounded so good!

OBPlayer is a stable and secure UNIX-based media streaming playout application that can operate as a standalone player or controlled over a network by a managing OBServer. It can be installed remotely at a transmitter site, in the studio or as multiple virtual headless processes.
OBPlayer is built with rules based intelligence to continue broadcasting no matter what happens. It functions by continually syncing with OBServer, looking for updated schedules, media, and priority broadcasts. If there is a blank spot in the schedule, it falls back to a Default Playlist. If that fails, it goes into Fallback Media Mode. If that fails, it plays from the analog input bypass. Finally, it will play a test signal as a last resort. OBPlayer will always play valid CAP (Common Alerting Protocol) Alerts at the highest priority.
OBPlayer can be run in a variety of configurations:
github.com/openbroadcaster/obplayer
OpenBroadcaster focuses on reliability, accessibility and scalability over a having a bloated range of half baked / buggy features. It has an organic AJAX interface built with Gstreamer, HTML5 and Javascript to deliver a web application in support of broadcast radio and TV automation, media asset management and dynamic community programming. One OBServer may manage one or more OBPlayer in a synchronized network configuration or have the server and playout on one device or VM. There is a robust Plugin Module Architecture with many modules extending the core server application. The server has a Documented API to enable sharing digital media assets and metadata with revocable secure keys.

When we developed HYSOLID, we were strongly aware that just as audio equipment is different from general industrial products, playback software is also a part of the “Audio” for which a special quality is required. By thinking that the special quality required for the playback software is “to aim a low-noise playback by reducing the load on the PC as low as possible,” we made this thought as the development concept of HYSOLID. HYSOLID has been developed by pursuing this simple concept from the design of the entire software structure to the detailed data manipulation. Please enjoy the difference of the sound by low load by all means.
Enabling playback by turning ON the PC -> Largely avoids the PC load generated from other software HYSOLID was designed so that you can use it by turning ON the PC in order to avoid the influence of other software as much as possible. You need not sign in to Windows unlike other general software.Since many of Windows programs in both OS and applications operate starting from the Windows sign-in, we have considered this design is particularly important for the PC audio.
HYSOLID has been enabled to operate with smartphone apps. We have reduced the PC load generated from the user interface (screen display and screen operation) on the PC like other software.
For the linkage between the smartphone apps and the Windows software, we have adopted the original bi-directional protocol that is designed to reduce the PC load at top priority by avoiding the general scheme or protocols such as DLNA and HTTP. Furthermore, the communication data itself has also been designed to be compact.
For the data format of the communication data, we have adopted UTF-16 for characters and little endian for numerical values so that the software on the Windows can handle them at the lowest load
In order to minimize the PC load of playback, the logic portion from reading sound source data from a file up to delivering it to the DAC of the driver becomes important.
We call this logic portion as “playback core,” and have implemented it particularly precisely.
When implementing the playback core, we dare to postpone the elements such as securing the readability that is emphasized in the general software development and reducing the implementation scale to prioritize to minimize the load that the playback core gives on the PC.
In reading the sound source data, HYSOLID has adopted a system to directly read the memory of the playback software without using the read buffer by the OS. This produces an effect to reduce the PC load when reading the sound source data.
