User interface front end supporting famous MP3Gain engine which analyzes and losslessly adjusts MP3 files to a specified target volume. A complete re-creation (made in QT5) of the original MP3Gain GUI, however it can be run on more platforms.
The shelfelf is a web frontend to send commands to your music player (itunes, mpd, squeezebox, xmms2, …). The shelfelf works with all tested browsers (except for Microsoft’s Internet Explorer, Amiga’s AWeb and lynx), but the interface is designed for tablets (with a browser running in fullscreen mode) like Apple’s iPad. Linux (or Mac OS X) with Apache webserver, MySQL database and the ability to send commands to your stereo equipment is required.
qaac requires Apple Application Support that is included in iTunes or QuickTime. If you are using 64 bit Windows, recent 64 bit iTunes (ver 12.1 or later) is recommended. 64 bit installer for iTunes (iTunes6464Setup.exe) includes both of 32 bit and 64 bit Apple Application Support, therefore you can run both of qaac.exe and qaac64.exe with its installation.
AAC-LC, AAC-HE, ALAC encoding are supported. m4a container (just a MP4 container with ‘M4A ‘ brand, created by Apple) is used by default, but you can also mux into ADTS.
Filenames and tags are treated with Unicode. Very long file names are supported.
Support for multichannel / surround.
Fine quality control over AAC encoding.
Support for hi-resolution / multichannel ALAC.
WAV, raw PCM, ALAC, and all LPCM formats supported by CoreAudio AudioFile interface (such as AIFF, CAF, and Sun/AU) are directly available as input. MP3 is also decodable through CoreAudio.
Cue sheet input is also available.
FLAC, Wavpack, TAK, and other LPCM formats are optionally supported when libFLAC.dll, wavpackdll.dll, tak_deco_lib.dll, and libsndfile-1.dll are installed.
Piped input is available for WAV and raw PCM.
Piped output (streaming) is supported for ADTS.
Automatically fetch tags from AIFF, FLAC, Wavpack, Tak, and ALAC. Major tags are copied to the result. Also, you can manually set tags via command line options.
.ogg is a free audio format alternative. It features sound quality that is generally higher than MP3, and has no licensing fees. Ogg Drop will encode audio tracks and CD’s into .oggs. Ogg Drop is entirely free.
Ogg Drop includes a CDDB lookup of the FreeDB music database. Stick an audio CD into Ogg Drop, and it should be able to identify the songs automatically, and tag the songs for you.
FLAC Frontend is a convenient way for Windows users not used to working with command lines to use the official FLAC tools. It accepts WAVE, W64, AIFF and RAW files for encoding and outputs FLAC or OGG-FLAC files. It is able to decode FLAC files, test them, fingerprint them and re-encode them. It has drag-and-drop support too. It is tested on Windows XP SP3 and Windows 7, but should work with Windows XP SP2 or newer. It requires .NET 2.0 or later.
FluidSynth is a real-time software synthesizer based on the SoundFont 2 specifications and has reached widespread distribution. FluidSynth itself does not have a graphical user interface, but due to its powerful API several applications utilize it and it has even found its way onto embedded systems and is used in some mobile apps.
Cross platform support (Linux, macOS and Windows to name a few)
SoundFont 2 support
SoundFont 3 support (vorbis-compressed SF2)
Realtime effect control using SoundFont 2.01 modulators
Playback of MIDI files
Shared library which can be used in other programs
FluidPatcher is a performance-oriented interface for FluidSynth built using wxpython to create a simple GUI that allows live editing, selecting, and playing of patches. A patch is a collection of settings such as soundfont presets for each MIDI channel, control-change/sysex messages to send when the patch is selected, and midi router or effects settings. Groups of patches are stored in banks, which are saved as human-readable and -editable YAML files. This allows a musician to easily create complex combinations of synthesizer settings ahead of time and switch between them on the fly during a performance.
Live playing: Play on your MIDI controller and hear the results
Customization: Create your own combinations of instruments/effects
Extendability: Use the included libraries to design your own implementations/software
LameXP is a free multi-format audio file converter that supports a variety of output formats, including MP3, AAC/MP4, Ogg Vorbis, Opus, as well as FLAC, and an even higher number of input formats. It also supports batch processing and can utilize multiple processor cores.
winLAME is an easy to use encoder for many audio formats, including MP3, Opus, Ogg Vorbis and more. winLAME uses the LAME mp3 encoder.
winLAME lets you read in audio tracks from CDs or encode audio files from your hard drive. The intuitive wizard-style user interface makes it easy to set up encoding settings. Multicore CPUs are used to parallelize encoding tasks.
