How to check files for errors?

It’s required and often helps to reduce support cycles to check files for errors before filing a bug report.

Symptoms of erroneous files are often

  • missing or wrong bitrate or length
  • audible blips or skips
  • tags seem to be sticky and cannot be removed

There are some really good tools to check the files for errors, namely

MP3val — validate and fix MPEG audio files

MP3 Diags — identifies many different issues in MP3 files


foobar2000 — multiple supported formats

See „Utilities > Verify integrity“ and „Fix VBR MP3 header“ from the right-click context menu.

Do yourself a favor and check your files, in case something seems to be odd.
