ABSeq vs MIXvs

ABSeq is an A/B comparison tool for producers and mixing and mastering engineers. Load two to four versions of a mix, a master or a reference track and switch between them in sync. Auto Gain matches their loudness first, so the louder version can't win by default. COMPARE MIXES LEVEL-MATCHED • One large A/B key switches tracks without losing your place in the song • Auto Gain matches every track to the quietest one by integrated loudness (LUFS) • Compare a new mix with the last one, a master with the pre-master, or your song with a reference track BLIND A/B TEST • ABSeq hides which track is which and shuffles them every round • Pick the one you prefer in each round, for 1 to 50 rounds • At the end, ABSeq shows which mix you picked and how often • Every round is level-matched, so you're judging the mix and not the volume LUFS METER AND TRUE PEAK • Integrated LUFS and true peak (dBTP) on every track • How much Spotify, Apple Music, YouTube, Tidal, Amazon Music and Deezer will turn the track down SEE WHAT YOU HEAR • Live spectrum analyzer • Pro: loudness graph, tonal balance view and an A/B difference curve that shows where two mixes differ, band by band SEQUENCER • Steps through your tracks for you, in time with each file's detected tempo • Choose the beat division and step order, then just listen CAR TEST AND HEADPHONE CHECK • Keeps playing and switching with the screen locked • Lock-screen controls play, pause and switch tracks • Works over Bluetooth and wired headphones, speakers and car audio YOUR FILES, YOUR DEVICE • Opens WAV, AIFF, FLAC, MP3, M4A and AAC files from the Files app • Everything is analyzed on your device.
