Adapted from the Web page:
AutoZen generates sounds meant to cause the user's brain waves to
shift to a different dominant frequency, resulting in an altered
state of consciousness. If you are under treatment for any
psychiatric or neurological disorder, you might want to approach
this with caution. You must use headphones for AutoZen to work at
all. The effect depends on each ear receiving a different tone,
and the combination of the inputs in the brain. If you are deaf
in one ear, it will not work.
[From the EsounD website:]
[W]hen two or more applications want to play sounds at the same time,
it's on a first-come, first-served basis. Whoever gets to the audio
device first wins. EsounD changes all of that...
The Enlightened Sound Daemon mixes several audio streams for playback by
a single audio device. You can also pre-load samples, and play them back
without having to send all the data for the sound. Network transparency
is also built in, so you can play sounds on one machine, and listen to
them on another.
forked-daapd is a DAAP (iTunes), MPD (Music Player Daemon) and RSP (Roku) media
server. It is a complete rewrite of mt-daapd (Firefly Media Server).
It has support for AirPlay devices/speakers, Apple Remote (and compatibles),
MPD clients, Chromecast, network streaming, internet radio, Spotify and LastFM.
It does not support streaming video by AirPlay nor Chromecast.
DAAP stands for Digital Audio Access Protocol, and is the protocol used
by iTunes and friends to share/stream media libraries over the network.
RSP is Roku's own media sharing protocol. Roku are the makers of the
SoundBridge devices.
MPEG Maaate (pronounce: ma:a:it) is a C++ toolkit to parse and
analyse audio data in the compressed domain by analysing MPEG-1/2
Layers 1-3 audio files. It makes the encoded fields of an MPEG
audio stream accessible (tier1) and provides some content analysis
functions like silence detection (tier2).
MPEG Maaate is designed in tiers: the first tier implements the
parsing of the MPEG audio stream, the second tier implements the
content analysis on the extracted field, and the third tier includes
any applications that are based on the extracted content.
LASH is a session management system for JACK audio applications. It is an
implementation of a proposal that originated from this discussion. Its aim
is to allow you to have many different audio programs running at once, to
save their setup, close them down and then easily reload the setup at some
other time. LASH doesn't deal with any kind of audio data itself; it just
runs programs, deals with saving/loading (arbitrary) data and connects
different kinds of virtual audio ports together (currently JACK and ALSA
sequencer ports). It can also be used to move entire sessions between
computers, or post sessions on the Internet for download.
Opus is a totally open, royalty-free, highly versatile audio codec.
It is standardized by the Internet Engineering Task Force (IETF)
as RFC 6716 which incorporated technology from Skype's SILK codec
and Xiph.Org's CELT codec.
Opus is designed to handle a wide range of interactive audio
applications, including Voice over IP, videoconferencing, in-game
chat, and even live, distributed music performances. It scales from
low bitrate narrowband speech at 6 kbit/s to very high quality
stereo music at 510 kbit/s. Opus uses both Linear Prediction (LP)
and the Modified Discrete Cosine Transform (MDCT) to achieve good
compression of both speech and music.
Mutagen is a Python module to handle audio metadata. It supports
FLAC, M4A, Musepack, MP3, Ogg FLAC, Ogg Speex, Ogg Theora, Ogg
Vorbis, MonkeysAudio, True Audio, and WavPack audio files. All
versions of ID3v2 are supported, and all standard ID3v2.4 frames
are parsed. It can read Xing headers to accurately calculate the
bitrate and length of MP3s. ID3 and APEv2 tags can be edited
regardless of audio format. It can also manipulate Ogg streams
on an individual packet/page level.
Audio::Ecasound provides perl bindings to the ecasound control
interface of the ecasound program. You can use perl to automate or
interact with ecasound so you don't have to turn you back on the
adoring masses packed into Wembly Stadium.
Ecasound is a software package designed for multitrack audio
processing. It can be used for audio playback, recording, format
conversions, effects processing, mixing, as a LADSPA plugin host and
JACK node. Version >= 2.2.X must be installed to use this
package. "SEE ALSO" for more info.
Test::Corpus::Audio::MPD will try to launch a new mpd server for
testing purposes. This mpd server will then be used during
POE::Component::Client::MPD or Audio::MPD tests.
In order to achieve this, the module will create a fake mpd.conf
file with the correct pathes (ie, where you untarred the modulE
tarball). It will then check if some mpd server is already running,
and stop it if the MPD_TEST_OVERRIDE environment variable is true
(die otherwise). Last it will run the test mpd with its newly
created configuration file.
playmidi is a small, quick midi file player using the level two sequencer
of the voxware 3.0 package to play on general midi devices or FM or
Gravis Ultrasound. If no files are specified, playmidi will give a short
summary of usage options. If more than one file is specified, you may
skip to the next file while the current one is playing by pressing your
interrupt (usually control-c) key. If you invoke playmidi while it is al-
ready running, it will allow you to control the currently running invoca-
tion until its death, after which time all waiting invocations fight to
go first.
