MP3val ~ Validate Your mp3s

MP3val is a small, high-speed, free software tool for checking MPEG audio files’ integrity. It can be useful for finding corrupted files (e.g. incompletely downloaded, truncated, containing garbage). MP3val is also able to fix most of the problems. Being a multi-platform application, MP3val can be run both under Windows and under Linux (or BSD).

The most common MPEG audio file type is MPEG 1 Layer III (mp3), but MP3val supports also other MPEG versions and layers. The tool is also aware of the most common types of tags (ID3v1, ID3v2, APEv2).

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!

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…

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 gapelss playback because the next file to be played is precached while the current file is playing.

Internet streams (Icecast, Shoutcast) are supported.
