This section of the tutorials will provide information on the file format(s) and impulse response uploading procedures for Fractal Audio Systems hardware and software.


File Type Overview


Like most DSP platforms, under the hood the Fractal Audio Systems hardware products convert external importable content to proprietary system exclusive ("SysEx" // .syx) format to be able to be utilized by the firmware. Unlike most DSP platforms, this is not necessarily transparent to the user as there are variations in how the user can compile these files to certain configurable subformats (Hi-Res, Ultra-Res, etc), and sub-configurations within each (raw, minimum phase transformed, trimmed, multi-file mixed, EQ shelf pre-application, etc). This is achieved through Fractal's proprietary Cab Lab software, which accepts wave audio (.wav) impulse response files as well as their proprietary encrypted .wav derivative format "IR" files (.ir) as input, and can then convert to .syx for direct drag and drop import.

As of version 3.12.0 of Axe-Edit and 1.7.0 of AX8-Edit, free Fractal editor companion software now allows for the import of .wav files, with all necessary conversion to proprietary formats being done behind the scenes and transparent to the user if so desired.

As also defined on the File Formats page, our .wav files that are most appropriate with this platform are:

Mono • 48 kHz • 200 ms



"Simplified"
Category
Libraries:
What to download:
..Mono-L.zip (if applicable)

Parent folder to use:
OwnHammer IRs\Mono 48000 Hz



"Comprehensive"
Category
Libraries:
What to download:
..Fractal.zip (RAW files) |or| ..Line6.zip (MPT files)

Parent folder to use:
OwnHammer\Fractal (RAW files) |or|
OwnHammer\Line6 (MPT files)




The files contained in the "Fractal.zip" are a copy/paste of the 48 kHz, 200 ms, non-minimum phase transformed files from the Wav directory. These files work best with Fractal's Cab Lab software, as it allows you to choose whether you leave the files in their raw time of flight - to which is unified and identical for all currently sold OwnHammer libraries containing raw, non-minimum phase transformed files - or use the proprietary minimum phase transformation function in that software when mixing and/or converting files. OwnHammer does not recommend ever using the "Auto Trim" option with OwnHammer IR's.

For those without Cab Lab who want to mix imported IR's with stock cabs via parallel cab blocks, minimum phase transformed .wav files will be necessary to import so that there are no phase issues that need to be corrected. If this is the case, simply also download the Line6.zip as these contain 48 kHz, 200 ms, minimum phase transformed files copied and pasted from the Wav directory.
