CRATEZip, RAR, 7-Zip, atau 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 tidak mengompres byte. Ia mendekodekan audionya, mengodekan ulang secara lossless (FLAC untuk integer, WavPack untuk float), mendeduplikasi take dan bounce yang berulang lintas file, lalu membangun ulang kembaran persis di ujung sana, dicek sampel demi sampel dengan 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.
Benchmark-nya
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.
Kenapa selisihnya ada
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.
Itu juga alasan Crate bisa jujur soal lossless: “lossless” bukan janji di kemasan, melainkan pemeriksaan SHA-256 pada tiap file, tiap kali.
Kapan zip sudah cukup
Kalau kamu mengirim beberapa MP3, sebuah PDF, atau folder kode, pakai saja zip: ada di mana-mana dan penghematannya tak akan terasa. Crate mendapat tempatnya begitu kamu memindahkan sesi sungguhan: banyak track, WAV besar, koneksi lambat atau mahal, dan tenggat yang tak akan selamat dari unggahan korup.
