fdkaac ~ Command Line Frontend For libfdk-aac Encoder


dkaac reads linear PCM audio in either WAV, raw PCM, or CAF format,
and encodes it into either M4A / AAC file.

If the input file is "-", data is read from stdin. Likewise, if the
output file is "-", data is written to stdout if one of streamable AAC
transport formats are selected by **-f**.

When CAF input and M4A output is used, tags in CAF file are copied into
the resulting M4A.

qaac ~ AAC / ALAC Encoder


qaac is a command line AAC / ALAC encoder frontend based on Apple encoder, strongly influenced by tmkk.pv.land.to/qtaacenc/.

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.

Features:
  • 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.

FluidPatcher ~ GUI & Automation

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.

Features:
  • 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
