audio-dc-offset-fixer

Audio Dropout Detector

json

Media

Detect brief signal dropouts and silent gaps in audio

audio-dropout-detector

file

Media

Speech-focused cleanup for noisy evidence and interview recordings: documented FFmpeg filter chains with presets for evidence clarity, broadcast, telephone band and transcription prep.

Codec Artifact Detector

html

Media

Compare an original master with its lossy encode and flag pre-echo, transient smearing, bandwidth loss and stereo damage, with per-event timestamps.

audio-codec-artifact-detector

Lossy Codec Preview Compare

file

Media

Hear and measure what streaming does to your master: encode to MP3, AAC or Opus at real streaming bitrates, decode back, and compare loudness shift, true-peak overshoot and headroom against the original — the Apple Digital Masters round-trip audition as a report plus downloadable preview files.

audio-lossy-preview-compare

Audio Digital Release Packager

file

Media

Package an album for digital distribution: distributor-profile compliance checks, cover-art validation, MP3 previews, FLAC archive copies and a delivery ZIP with a README and machine-readable manifest.

audio-digital-release-packager

Audio Gapless Album Validator

html

Media

Validate an album for gapless playback: inter-track seam gaps, pre-roll and tail silence, encoder delay metadata, and sample-format consistency across every track.

audio-gapless-album-validator

Mastering Before/After Report

html

Media

Compare a source mix against its master: integrated LUFS, true peak, LRA, DR dynamic range, crest, spectral balance and waveform strips, with every delta spelled out.

Harshness Tamer

file

Media

Detect and dynamically attenuate harshness in the 2–5 kHz presence band — a dynamic-EQ-style cut that only bites when the band actually plays loud.

audio-harshness-tamer

Mud Remover

file

Media

Detect and reduce 150–500 Hz low-mid buildup — the stacked-fundamentals mud that turns a mix boxy — with a measured, focus-tuned parametric cut.

audio-mud-remover

Audio Kick-Bass Phase Aligner

file

Media

Compare kick and bass timing/phase in the low band, report the offset and polarity, and export the corrected track with sample-accurate alignment.

audio-kick-bass-phase-aligner

Audio Master Reference Match

file

Media

Match your mix's tonal balance and loudness to a reference track and export the corrected master, with a before/after third-octave band report.
