under the hood.
real-time codec engine
encodes + decodes through the actual spotify / apple codecs while the audio streams. no bouncing, no exporting, no waiting.
sample-accurate null
the dry signal gets auto-aligned against the delayed codec output, so the difference is genuinely the codec — not a phase error.
running LUFS + null depth
ITU-R BS.1770 loudness settles toward the track's true value as it plays; null depth shows how close the codec stays to your source.
auto −14 LUFS trim
optionally trims your input toward streaming's −14 LUFS target, so you audition the codec at the level people actually hear.
reported latency + PDC
codec latency is reported to your DAW for automatic delay compensation — the null stays lined up and the panel shows the exact ms.
every tier, one insert
jump between spotify's tiers and apple's AAC without reloading. premium vs data saver vs apple music, back to back.
the tiers
every subscription tier, decoded.
these are the actual encoders behind each plan — not an approximation of them.
spotify
ogg vorbis · mac + windowsvorbis is royalty-free, so these tiers run everywhere NULLIFY does.
✓ vorbis is patent-free — zero royalty exposure
apple music + web
AAC · mac onlyencoded through macOS's own AudioToolbox — apple's licensed system encoder, so no patented codec ships inside NULLIFY.
✓ uses the OS encoder already on every mac — mac-only by design
formats
same engine everywhere.

demo mode is free: everything works, the audio just dips for a sec every ~20s and the apple music tiers are locked. a key removes both.
