eSpeak is a compact open source Linux and Windows speech synthesizer for English and other languages. eSpeak uses a “formant synthesis” method. This allows many languages to be provided in a small size. The speech is clear, and can be used at high speeds, but is not as natural or smooth as larger synthesizers which are based on human speech recordings.
eSpeak is available as:
- A command line program (Linux and Windows) to speak text from a file or from stdin.
- A shared library version for use by other programs. (On Windows this is a DLL).
- A SAPI5 version for Windows, so it can be used with screen-readers and other programs that support the Windows SAPI5 interface.
- eSpeak has been ported to other platforms, including Android, Mac OSX and Solaris.

Squash ~ Learning Music Player
Squash is a C / Ncurses based Unix music player. It supports mp3, ogg and flac through libraries. Squash uses statistics to determine songs to play automatically. It garners this information through whether or not a song is skipped. Squash also avoids picking the same song twice. Thus Squash is like a radio station that plays the songs you like — and you don’t even have to call in requests!

Levelator ~ Enhance Your Podcast
Levelator® adjusts the audio levels within your podcast or other audio file for variations from one speaker to the next, for example. It’s not a compressor, normalizer or limiter although it contains all three. It’s much more than those tools, and it’s much simpler to use. The UI is dirt-simple: Drag-and-drop any WAV or AIFF file onto The Leveler’s application window, and a few moments later you’ll find a new version which just sounds better.

bs2b ~ Bauer Stereophonic-To-Binaural Headphone DSP
A typical stereo records are being made to listen by speakers. That is a sound engineer makes the stereo mix to the adaptation of sound for listening of one channel by both ears. Therefore, you will be tired during a long time headphone listening more by a super-stereo effect than by a poor design of headphones. What’s missing in headphones is the sound going from each channel to the opposite ear, arriving a short time later for the extra distance traveled, and with a bit of high frequency roll-off for the shadowing effect of the head. And the time delay to the far ear is somewhat longer at low frequencies than at high frequencies. The Bauer stereophonic-to-binaural DSP (bs2b) is designed to improve headphone listening of stereo audio records…

Denemo ~ Freeware Music Notation
Denemo is a free music notation program for GNU/Linux, Mac OSX and Windows that lets you rapidly enter notation which it typesets using the LilyPond music engraver. Music can be typed in at the PC-Keyboard, played in via MIDI controller, or input acoustically into a microphone plugged into your computer’s soundcard.

Opus ~ Interactive Audio Codec
Opus is a lossy audio coding format developed by the Xiph.Org Foundation and standardized by the Internet Engineering Task Force, designed to efficiently code speech and general audio in a single format, while remaining low-latency enough for real-time interactive communication and low-complexity enough for low-end embedded processors. Opus replaces both Vorbis and Speex for new applications, and several blind listening tests have ranked it higher-quality than any other standard audio format at any given bitrate until transparency is reached, including MP3, AAC and HE-AAC.

MOC ~ Music On Console
MOC (music on console) is a console audio player for LINUX / UNIX designed to be powerful and easy to use.
You just need to select a file from some directory using the menu similar to Midnight Commander, and MOC will start playing all files in this directory beginning from the chosen file. There is no need to create playlists as in other players.
However if you want to combine some files from one or more directories on one playlist, you can still do it. The playlist will be remembered between runs or you can save it as an m3u file and load it whenever you want.
Need the console where MOC is running for more important things? Need to close the X terminal emulator? You don’t have to stop listening to the music – just press q and the interface will be detached leaving the server running. You can reattach it later, or you can attach one interface in the console, and another in the X terminal emulator, no need to switch just to play another file.
MOC plays smoothly, regardless of system or I/O load because it uses the output buffer in a separate thread. It provides gapless playback because the next file to be played is precached while the current file is playing.
Internet streams (Icecast, Shoutcast) are supported.
