This section of the tutorials will provide information on the basic nature of impulse responses, and how to use the options provided in the OwnHammer libraries.



Impulse Response Overview



Impulse response capture is a way to measure the linear elements of a system, and retains the ability to represent things like frequency and phase response, and reverberation decay. In the application realm of guitar equipment such as provided on the OwnHammer website, they are able to duplicate the "sound" of mic'd up guitar cabinets with EXTREME accuracy. The concept is simple - set up mics the way they would be for studio and live applications, and capture the sound of the cabinet, speaker, mic(s), and outboard gear in that signal chain in that exact configuration. Once the impulse responses have been compiled (which are sold on the OwnHammer site), they can be used in a convolutin reverb type loading device - be it a plugin in a DAW, or "cabinet block" in an outboard hardware unit - to import the file into and add that sound to a signal chain. Want a different sound? Load a different file! Which files should be chosen for a certain sound? This will be explained in the usage sections below.

Not all cabinets and speakers are created equal, speakers especially can vary WILDLY between specimens that should - as their make and model title would infer by being "identical" - sound the same but don't from both manufacturing tolerance deviation and time/wear/environmental factors. The OwnHammer brand has spared no expense and collected some of the most amazing and sought after pieces in electric guitar history dating from modern times back to its origins, and poured over hundreds of speakers and dozens of cabinets to find the very best sounding specimens to present to you at an infinitesimal fraction of the cost of acquiring these pieces 'in the real world'. Add the incredible amount of experience in mic'ing guitar cabinets, co-pioneering the commercial IR market, advancing the techniques involved in the stimulus and capture processes beyond any other provider, and high profile engineer, artist, and parallel industry developer involvement and endorsement, and you have the unquestionable highest echelon of professional guitar and bass loudspeaker impulse response products to choose from with OwnHammer.



Getting Started



First and foremost - which cabs and speakers are for you? Most likely, you're playing through a guitar amp or a model of a guitar amp, and pairing the cabinet and speaker to that make and model of amp is usually a great starting point from which you can branch out and experiment with later if desired. Google, YouTube, etc, are great resources for looking up what cabs and speakers go best with your guitar, amp, and playing style. Start there, and once you have an idea of what you're looking for you can select the library or libraries that are going to fit with your sonic objective and use application.

Once a library or libraries have been chosen, now it's time to investigate the IR options! The majority of the time, the multi-mic mixes are the desired choice. Not only is this the way many if not most studio recordings are conducted, but the OH mixes use intentional slight phase misalignment to add organic qualities to the sound that are highly desirable both in the way they "feel" to play and how they sit in a mix.
