mp3guessenc ~ Analyze Audio mpeg Files
… a small utility for analysis of audio mpeg files and detection of the encoder used (when layer III).
Further, mp3guessenc can detect many details about the mpeg audio stream and print out lots of useful information.
Supported streams are mpeg 1, mpeg 2 and unofficial mpeg 2.5 – layer I, layer II and layer III of course. Xing tag, lame tag, VBRI tag, Id3 tags (both 1.x and 2.x), APE tags (both v1 and v2), Lyrics3 tags (both v1 and v2) and MusicMatch tag (any version) are detected as well.
Features:
- scan mpeg 1/2/2.5 streams, layer I/II/III
- guess encoder used (lame/gogo/xing/helix/fhg(new, old and ancient)/blade)
- also detects mp3pro and mp3surround streams (even with OFL)
- support for large files (up to 2^60 bytes!)
- free format streams supported
- full statistics for the stream (audio mode, frame histogram, block usage, ancillary data)
- crc16 verification
- vbr tags by xing/lame + VBRI tag by fhg
- detection of ID3 v1/v2 + APE tags + Lyrics3 tags + MusicMatch tag
- verify integrity of lame tag

tonedeaf ~ Online Hearing Test
Test your musical skills in 6 minutes!
While working at the music and neuroimaging lab at Beth Israel/Harvard Medical School in Boston, I developed a quick online way to screen for the tonedeafness. It actually turned out to be a pretty good test to check for overall pitch perception ability. The test is purposefully made very hard, so excellent musicians rarely score above 80% correct. Give it a try!

aveX ~ Linux ABX Testing
aveX is a free software for running and monitoring ABX listening tests. It works as a Jack (Jack Audio Connection Kit) client and is able to send test-status messages over a network for monitoring purposes. ‘A’ and ‘B’ audio files are read in pairs from a list and played in randomized order, the ‘X’ audio file is also randomized and is either ‘A’ or ‘B’ (double-blind test).
The listening test results are written after every choice in a file in text format.
The program is configured by filling in a very simple XML file.

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).
