Wave Audio Format



Yes, if the platform in question accepts wave audio format (.wav) files in 24-bit resolution, mono channel count, and at 44.1, 48, 88.2, or 96 kHz sample rate.

If verification is necessary prior to making a commercial purchase, this can be accomplished via the IR Freebie.




This question is best asked to the loading platform provider, as they will have official knowledge of their platform's operations and requirements. OwnHammer wave audio format IR's are provided in 24-bit resolution, mono channel count, and at 44.1, 48, 88.2, and 96 kHz sample rates, should you need to confirm those specifics against 3rd party documentation or with 3rd party platform support.

In DAW environments, it is always best to use IR files that are the same sample rate of the project/session, as you cannot be certain that the IR loader you import the IR into has sample rate conversion correction capabilities.

Additionally, in the event that the platform in question finds itself in the below list, some information on known/submitted platforms and their native operating formats and requirements can be found at:

Line 6 Format




No. Libraries in this category contain files that are in Line 6's proprietary file formats, which are uniquely encrypted and only readable by the Line 6 products built to accept these file types. This currently includes:

Software:
  • Helix Native
  • Metallurgy Collection
Helix Family: HX Family: POD Family:




No.




[1] log into your account on the Line 6 website (line6.com/account/)
[2] go to line6.com/account/addons/ or click on Marketplace Downloads
[3] click on the library you wish to download





Within Helix Native, HX Edit, POD Go Edit, etc, typically to the left hand side is where the IR bank is located. Look for and select a tab that says "IRs", "Impulses", etc. The slot list that populates below is where you will import and organize .wav and/or .hir impulse response files.

From here, the following are actions that can be taken to import .wav and/or .hir impulse response files into an IR bank slot:

[1] Drag and Drop

From a file explorer window, simply drag and drop either .wav or .hir impulse response files into a certain slot.

[2] Right Click > Import

In any slot, right click and then select "Import", then find the IR file you wish to load.

[3] UI Import

First, select the slot you would like to import an IR into, then select "Import" at the top of the slot list to browse to an IR file you would like to load into that slot.




First and foremost, content sold in the Line 6 Marketplace is copy protect encrypted. In order to load Marketplace IR's and Presets into a compatible Line 6 hardware device or software program, the latter needs to be registered to the same account that the IR's/Presets are purchased from and assigned to. More often than not, those experiencing a license error simply have not registered their hardware/software yet, and doing so will resolve the licensing error.

If you have issues loading files into a particular Line 6 hardware or software product, Line 6 support can be reached at:

line6.com/support/tickets




The specifics are considered proprietary, with any relevant and/or disclosable information to be found on the product page or in the PDF documentation included with the library package.




While the specifics are not and will not be publicly documented, the filenames imply either the type of cabinet that IR is derived from or the sound that can be expected from it.

Fractal Audio Format




No. Libraries in this category contain files that are in Fractal Audio's Standard and UltraRes ".syx" file formats, which are proprietary encryptions only readable by the Fractal Audio products built to accept this file type.




The file types provided in this library are Standard and UltraRes .syx files, which can be dragged and dropped via Fractal editor software into any Fractal hardware unit that has cab block functionality EXCLUDING the original 1st generation Axe-Fx Standard and Axe-Fx Ultra.

To see if your particular model of Fractal Audio device will accept these files, try the .syx format files in the IR Freebie.




No.




Files with the .syx extension are usable in compatible Fractal Audio modeling hardware, and can be dragged and dropped onto cab storage slots via Axe-Edit software. Please see the Fractal Tutorials page for additional information. If you have issues using Axe-Edit, Fractal Audio support can be reached at:

General




Impulse responses are small wave audio (.wav) files that contain linear measurement data consisting of the frequency response, phase response, and reverberation decay of a measured system. These files are in a format that can then be read, interpretted, and applied by software containing a convolution reverb algorithm.

In the context of how they are primarily implemented and sold on the OwnHammer website, these systems are mic'd up guitar and bass cabinets/speakers. The data they capture representats the linear response of the cabinet, speaker, microhpone/microphone placement/multi-microphone mix, and the outboard recording equipment.

Additional information on how to use the impulse responses offered on the OwnHammer site can be found in the Tutorials section of the website.




A) With Software Virtual Amps

There are two primary methods of application here:

I. Standalone
Connect your electric guitar/bass to a DI/Mic-Pre then to an analog-to-digital conversion interface (line-in of sound card or usb audio input device, etc) or into the instrument-in section of an all inclusive or proprietary interface. Once you are able to get your instrument's output "in the box", you will need to launch a standalone amp sim program that has a convolution reverb engine capable of importing external impulse response files. Simply navigate to the cabinet simulation portion of the host and search for a button that will allow you to import external .wav files.

II. Plugin via DAW Host:
Get your instrument "in the box" as mentioned above, but now you will need to launch the virtual amp sim plugin as an insert on the audio track that you are capturing the instrument on, or on a bus that the instrument track is being sent to. You can import the impulse response file(s) either [a] through the convolution reverb engine built into the virtual amp sim plugin (if it is capable of importing external files), or [b] by disabling the cab/speaker simulation in the virtual amp sim plugin and placing a convolution reverb plugin instance after the virtual amp sim plugin either on the same track or on a bus that the track is being sent to.

If the convolution reverb host has a "Wet/Dry" mix knob, setting it to 100% wet will force all of the sound through the IR, and is the desired setting in standard application.

If you are unaware if/how you can import IR's into your host of choice, please see the documentation for that product provided by the respective developer.

B) With Amp Modelers

Again, there are two primary methods of application here:

I. Within the Patch
Connect your electric guitar/bass to the input of your amp modeler. Import the impulse resonse of your choice into a cabinet slot via your platform's editor software, and select that slot within the cabinet block/section of your patch.

I. Within the DAW
Only recommended for recording applications - in this case, disable all cabinet simulation within your patch, and import the impulse response into a convolution reverb plugin inserted on the track that your modeler is routed to in your DAW session, or on a bus that track is being sent to.

C) With Guitar/Bass Preamps

Connect your electric guitar/bass to a preamp and then into your conversion interface through a line level input. Once the signal is "in the box" and feeding a track in your DAW, the first insert you should assign to it is a power amp simulation, such as Ignite Amps' TPA-1. Once the "full amp" signal is now in place, you can follow the power amp simulation with an IR loader/convolution reverb plugin instance on that audio track or on a bus that the track is being sent to, depending on your workflow. Without power amp simulation, the overall sound may be very mid heavy, with much less low and top end than one would normally expect, be accustomed to, or desire.

If the convolution reverb host has a "Wet/Dry" mix knob, setting it to 100% wet will force all of the sound through the IR, and is the desired setting in most applications.

D) With Guitar/Bass Amps

Connect your electric guitar/bass to an amplifier head or combo. Connect the speaker out of the amplifier with a SPEAKER cable to a dummy load that [a] is rated at the same impedance you are sending out of the amp [b] is rated at DOUBLE the wattage of the amp you are sending from, and [c] is equipped with a line out. It is recommended that even if you are attenuating at 100%, a speaker cabinet of the same impedance rating as the amp out and dummy load is connected via a SPEAKER cable to the dummy load's speaker out/through UNLESS IT SPECIFICALLY STATES THIS IS UNNECESSARY IN THE USER MANUAL OF YOUR DUMMY LOAD. Turn the line out volume of the dummy load and the amp's master volume to zero, and connect the line out of the dummy load to either the DI/line level in of a mic pre or to the line in of your audio interface. Then begin the process of setting the amp where you like it, and where you can get away with that within the output of the line level volume on the dummy load and/or any line level preamps that may be following it. Once you have your sound "in the box", you can follow it with an IR within your DAW host either by placing a convolution reverb plugin instance on the audio track or on a bus that the track is being sent to.

If the IR loading host has a "Wet/Dry" mix knob, setting it to 100% wet will force all of the sound through the IR, and is the desired setting in most applications.

No. This could be from the perspective of competitive advantage through obfuscation, or that the information simply was not kept record of. At the end of the day, knowing the details of a multi-mic mix doesn't change how it sounds, so your ears will serve you better than your eyes in determining if a mix is right for your application.




No. Legacy libraries that have been discontinued have been so because they either do not meet the current sonic requirements and therefor do not serve current brand reputation, do not and/or can not meet the current file format standards and presentations, and/or were part of third party agreements/collaborations that are no longer active. If it cannot be found in the current product menu system, through the search function, or in your order history, it is simply no longer available.
