A new program, Audio Tester, by James Chapman has been released. It is an all-in-one solution that replaces his former OggTester and FLACTester apps. This new utility works on Windows 2000, XP and Vista, and allows you to drag and drop folders of audio files to be tested for errors.

The program is multi-format aware, and automatically tests the integrity of FLAC, MP3, Ogg Vorbis and WavPack files. An easy to use, graphical interface rounds out this handy utlity to test the accuracy of your audio files. Easily find errors and possible corruption in your audio collection files.

is this program still recommented to use?

i scanned my whole library with it about one year ago and deleted all the TRUNCATED, CRC ERROR and rebuild audiostream (with foobar)
where i had sync errors or bad id3 header. afterwards those were gone.

now i checked my library again and there are again thousands of files with sync errors.

the foobar file integrity component does not find any problem with those files, nor can i hear any when listening to them
but i want my whole library to be perfect and without uncompliant/corrupt files.

should i continue using audiotester? should i care about those sync errors? should i use the "rebuild stream" functionality in foobar? (does it reencode the file and thus have generationloss?)
should i rather switch to mp3diag for scanning mp3 files and foobar for scanning my flacs? (since it just checks the embedded md5 sum, like flac -t)

I've been reinstalling my PC, hence the late reply.

That's the only question I can answer, and it does not re-encode the audio, only rearranges the valid frames. It might discard anything unrecognised as valid MPEG audio or unknown tags, so if you're reliant on something non-standard embedded in a .mp3 file or even hoping to recover a bad frame somehow, make a backup of the file first.

As to having thousands of sync errors, unless you're getting MP3 files from dubious sources I'd be suprised if it wasn't a change to some tagging standard or lame header (silent MP3-compliant frame) that occurred since 2007 that's being misinterpreted by old software that I've never used myself.

I'd have expected foobar2000's console will probably report any genuine problems in any format for which it has a decoder, and I presume the file integrity component would do a test decode of every file (otherwise use the Decode Speed Test component and view the console). The console should report any errors worth knowing about, and despite the disclaimer for the File Integrity component, it says it decodes, so I'd have thought this would cause the same information to be logged in the console.
