CRATEZip, RAR, 7-Zip, au 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.
Crate haibani baiti. Husimbua sauti, huisimba upya bila hasara (FLAC kwa integer, WavPack kwa float), huondoa nakala za takes na bounces zinazojirudia baina ya faili, na hujenga upya pacha kamili upande wa pili, ikikaguliwa sampuli kwa sampuli kwa 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.
Kipimo
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.
Kwa nini pengo lipo
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.
Ndiyo maana pia Crate inaweza kuwa mkweli kuhusu kuwa bila hasara: “bila hasara” si ahadi kwenye kisanduku, ni ukaguzi wa SHA-256 kwenye kila faili, kila mara.
Wakati zip inatosha
Ikiwa unatuma MP3 chache, PDF, au folda ya msimbo, tumia zip: ipo kila mahali na akiba isingekuwa na maana. Crate hupata nafasi yake pale unapohamisha kipindi halisi: track nyingi, WAV kubwa, muunganisho wa polepole au wa gharama, na tarehe ya mwisho isiyoweza kustahimili upakiaji ulioharibika.
