Hi guys !

Few days ago i found the MT'ed version of the latest(?) Brotli. (V1.0.1.)
The pack includes the following x86 and x64 EXEz :
Brotli 1.0.1
Lizard V2.0
LZ4 V1.7.5
LZ5 V1.5
ZSTD (V1.2.0,obsolete)

BrotliMT : (STDIN/OUT @ de/compression)
Painfully slow @ compression (4 threads ,~ 1.3 MB/s on a i5-6600),but many times better than ZSTD ultra/22 and decompresses FASTER.

Wavpack : (STDIN/OUT @ decompression)
Pretty slow compression ,too ,but ~2 times faster at decompression than the internal TTA and only a BIT worser sometimes !
Download link only.

LZMA2 @ 1GB : (STDIN/OUT @ de/compression)
No comment.

Usage : See included arc.ini

Real test : (Ashes of singularity) (SSD to RAM-disk)

Main files : 9,394,584,114 bytes
ZSTD @ Ultra/22 : 0 mins 50 sec
Brotli @ MAX : 0 mins 38 sec (smaller with 150 Megas)

Audio files : 707,604,104 bytes
TTA : 250,751,352 -> (comp : 22.19 mB/s ,decomp : 24.99 mB/s)
WavPACK64 : 255,676,198 -> (comp : 00.92 mB/s ,decomp : 54.43 mB/s)

Another audioset : (Ashes of singularity - Escalation)
Audio files : 1,063,095,808 bytes
TTA : 356,992,729 -> (comp : 23.84 mB/s ,decomp : 25.24 mB/s)
WavPACK64 : 356,717,989 -> (comp : 00.92 mB/s ,decomp : 55.23 mB/s)

I hope it was useful. :)
