Audio Gapless Album Validator

Upload the album as individual audio files or one ZIP and get a seam-by-seam gapless audit. For every track the tool decodes the head and tail windows and measures the leading (pre-roll) and trailing silence against a configurable dBFS threshold, giving the audible gap in milliseconds and samples at each track boundary. MP3 tracks get their Xing/Info header parsed for the LAME encdelay/encpadding fields that gapless-aware players use to trim encoder padding — a missing or zeroed tag is flagged because every player will then add the encoder delay at each seam. FLAC, WAV and ALAC are inherently gapless, so only seam silence and format consistency matter there. Album-level checks confirm a uniform sample rate, channel count and codec so nothing resamples or glitch-stitches at playback. This validates your files; it does not modify them.
