CRATEZip, RAR, 7-Zip, o Crate?
General-purpose zippers were built for documents and code. They do shrink an audio session — and then they stop, because a waveform is a wall of random bytes to them. Crate was built for one job: moving audio sessions. It reads the stems, packs them to roughly half the size of a zip, and proves every byte arrived perfectly.
Try it yourself: take a finished multitrack session, zip it, then pack it with Crate. Across the twenty real client sessions in our benchmark, the zip came out between 1.38 and 2.46 times the size of the .crate package. The zip is not doing nothing — it saved a median of 51.5% (per-session range 15–88%). It simply runs out of things to find, because a byte-level compressor never sees the waveform underneath.
Hindi kino-compress ng Crate ang mga byte. Dine-decode nito ang audio, muling ine-encode nang lossless (FLAC para sa integer, WavPack para sa float), dine-deduplicate ang mga inuulit na take at bounce sa mga file, at muling itinatayo ang eksaktong kambal sa kabilang dulo — tinitingnan nang sample-for-sample gamit ang SHA-256.

Percentages are the packed size as a share of the original session — lower is smaller. Figures are pooled across the eleven mixed sessions of the current benchmark, every archiver at its strongest setting (zip -9, RAR -m5 -s -md1g, 7-Zip -mx=9, Crate on Smallest), every result restored and compared byte for byte. Per-session ranges are wider — the Impact page carries them lane by lane.
Ang benchmark
One run, one machine, nothing else running. Twenty real client sessions — mixed, loop-heavy, stem exports and dense live recordings — each packed by Crate on both of its presets and by ten other archiver configurations set for maximum compression, every run restored and compared byte for byte. Sessions are pooled into four material classes so no one session can stand in for the rest. The full tables are on the Impact page, engine by engine.
Bakit umiiral ang agwat
A zipper looks for repeated byte patterns, and a session does hold some: headers, long stretches of silence, whole files that appear twice. That is worth the 15 to 88% a zip finds on audio sessions — about half, at the median — and then the search is over, because the low bits of a 24-bit WAV are noise to it. Crate instead does what an audio engineer would: it reads the actual waveform, stores it in a lossless audio codec, notices when two tracks are the same take (on by default) and — on the Smallest preset — when a bus is the sum of its stems, keeping only what's unique. Then it reassembles a byte-identical copy and proves it.
Iyan din ang dahilan kung bakit maaaring maging tapat ang Crate tungkol sa pagiging lossless: ang “lossless” ay hindi isang pangako sa kahon, ito ay isang SHA-256 check sa bawat file, sa bawat pagkakataon.
Kailan sapat na ang isang zipper
Kung nagpapadala ka ng ilang MP3, isang PDF, o isang folder ng code, gamitin ang zip — nasa lahat ito at hindi mahalaga ang matitipid. Kinikita ng Crate ang lugar nito sa sandaling naglilipat ka ng tunay na session: maraming track, malalaking WAVs, isang mabagal o mahal na koneksyon, at isang deadline na hindi makakaligtas sa isang sirang upload.
