Download Acoustic Guitar Impulse Response
Rochell Estrello
I recently purchased the Past to Future Martin D-18 impulse response files from here. These IR's were recorded in Mono, Stereo, with 3 Mics and all with different mic positions. (All Vintage Neumann mics with Telefunken mic pres). Digital and audio tape versions are included. Here're clips of the acoustic guitar bridge pickup DI from a song I'm mixing with and without the digital stereo 3 IR effect in the MConvolutionEZ.
I use them for mixing. I inserted the MConvolutionEZ IR player in the FX bin of a mono acoustic guitar bridge pickup track, auditioned several of the D-18 impulse response (IR) files and selected the one I liked best.
This is really interesting Bill, I might also give it a shot. Generally, the piezo pickup on acoustic guitars sounds awful when recorded, scratchy, at best it is something that might be used at a very low level to add bite to to the microphone recorded acoustic track but I never bother with it. I use the piezo pickup when first sketching out a song simply because I can plug the acoustic in without worrying about background noise and because it's easier just to plug in. But that is just a guide track and is never used in the completed song. I'll muck about with it, see what happens.
@Bill Phillips & @User 905133, Again, I apologize. I understand using an impulse response to recreate a space but I am not familiar with using an IR to recreate the sound of an instrument. Thank you for your responses.
I'm not a DSP guy; there are people on the forum who know a lot more about audio than I do, but I'll step in anyway. Two digital filters are FIR and IIR which are Finite Impulse Response and Infinite Impulse Response so impulse responses are used in filters. I think speaker IRs are basically filtering (EQing).
An IR essentially defines the reverberation characteristics of an environment (guitar body, room, et. al.), so it can turn the dry response of a lackluster environment/instrument into something more realistic. It would not change the timbre of the underlying source, so it won't "convert" electric string impulses to acoustic strings, make old strings sound new, etc.; but it would bring life to a piezo pickup so it could be blended to sound more like an acoustic recording.
You may try to record the guitar's response to a very short hit of damped strings, approximating a broadband impluse excitation.
(no idea what comes out of this, but it's similiar to the shot method used for room IRs).
You're right about the strings sympatethic resonance if your source signal is a guitar already, I was rather coming from my own experiments with acoustic guitar IRs applied to synthetic (pluck) sounds. In that case, including the strings can be desirable.
Nice idea to try out with the tactile transducer, look forward to experimenting with this when I get outta here eventually. A while back I saw a crowdfunding campaign for an acoustic guitar that used this idea to apply fx to itself and amplify out the body...not sure what came of that but I thought it was a cool idea.
They're all pretty much the same really just on the physics of it but piezos don't have to be twangy and brittle ... bass response is very much improved by exerting pressure on the crystals - little plastic clamps- even clothes pegs... but grab it on hard. Sticking a couple of cheap piezos under the feet of a cello bridge for example can give you a deep meaty sound - serious pressure. Same with small pickups under individual strings on a guitar bridge - tunable with the right kit.
I've gone down the rabbit hole of acoustic guitar IRs after having looked at Tonedexter, LR Baggs Voiceprint, etc. Anyone find any new resources since last spring? Here's something I found that looks interesting:

The Helix has support for Impulse Response (IR) blocks. So it seemed like it should be possible to use an acoustic guitar body IR block to free up the Aura for other uses, and further simplify my live rig. The rest of this post describes how to extract a body image from the Aura that can be used in a Helix IR block that reproduces the body tone.
Using body images as IRs in Helix really opens up the possibilities for using Helix as an effects processor for many instruments besides electric guitar and bass. Body images such as those in the Fishman Aura Spectrum really do turn a quacky piezo sound into the wonderful, complex fullness of a good acoustic guitar.
Hey. Thanks to everyone for the answers. Some really interesting ideas and opinions in there. It was just something I was musing about, how far I could push things in terms of getting different sound out of an already recorded acoustic guitar part. Cheers!
To load a static Impulse response (be it an Acoustic Impulse response or one captured from a traditional guitar cabinet) simply navigate to the IR loader tab in Torpedo Remote and select up to two files to load onto either of the IR Slots (IR A and IR B). You can then use the IR A and IR B channel controls to refine the blend of your IRs within the context of your OPUS preset.

The BAIO A is the multi-effect pedal with built-in IR for acoustic guitar, classical guitar and acoustic bass from Eko Guitars. It features 8 IRs of microphoned acoustic instruments, full tone controls, compressor, antifeedback, chorus, tremolo, reverb, delay, built-in tuner with mute function, instrument input and jack output, stereo output for headphones, bluetooth connection and dedicated usb ports for use as an audio interface for both PC/Mac and smartphones. The ideal pedal with which you will have your sounds with you at all times.BAIO A multieffect pedal for acoustic guitar by Eko Guitars OverviewAt 16cm long, just 6cm wide and 260g in weight, BAIO is the all-in-one multi-effect system that offers all the features and functionality essential to the modern guitarist and bassist. Easy to carry and super durable thanks to its metal chassis, it allows total management of your sound.
For the preamp section you have a three-band eq, compression and antifeedback. The modulation section, accessible via the Mod control, allows you to add chorus and tremolo; delay and reverb can be activated from the dedicated knob, delay time and reverb amount adjustable from the Time knob. The IR control allows you to select from eight Impulse Responses created especially for BAIO by Massimo Varini, who has chosen and adapted some of the best DrapSound-branded IRs. With the Out control you manage the output volume, and via the three footswitches you can switch from Preset mode for changing them, to Live mode that will allow you to manage IR, Delay/Rev, Chorus/Tremolo and preamp section separately. Also with the footswitches, you can operate Bluetooth which will allow you to play your favorite backing tracks via an external device or activate the built-in tuner, with which you can also completely mute the output signal.
The PowerCab 112 Plus active speaker system was purpose-built for guitar players who use amp modeling technology. Developed by Line 6, pioneers of modeling amps and effects, the PowerCab 112 Plus does for guitar speakers what their Helix series did for guitar processors. The PowerCab 112 Plus is the only speaker system that provides both a neutral, full-range response as well as proprietary speaker modeling technology for a dynamic, amp-in-the-room experience.
While the PowerCab 112 Plus comes ready to use with six meticulously modeled classic guitar speakers, it also gives you the freedom to craft your own signature tone. With 128 user-loadable preset slots, you can upload third-party impulse responses and adjust settings to your heart's content using the free Powercab Edit software. All presets are recallable, MIDI-controllable and can be used in Flat, Speaker Modeling or IR mode for maximum flexibility.
While designed to integrate seamlessly with Line 6's Helix series, the PowerCab 112 Plus pairs perfectly with any amp modeler, preamp or stompbox-based amp simulator. In Flat mode, its full-range response accurately amplifies the sound of your presets as intended. But the PowerCab 112 Plus's crowning achievement is its groundbreaking Speaker Modeling technology. Rather than cabinet emulations or impulse responses, Speaker Modeling provides dynamic speaker models of six classic designs, allowing you to experience the sound and feel of playing through those vintage cabs.
The PowerCab 112 Plus accomplishes its range of tones through a custom hybrid coaxial speaker combining a lightweight cone and 2\" voice coil for authentic guitar speaker response with the extended range of a pro PA driver. The end result is an active guitar speaker system that looks, sounds and responds like a real guitar cabinet while also providing a neutral, full-range platform for your modeler's cabinet emulations. For guitarists seeking the ultimate tone, feel and flexibility, the PowerCab 112 Plus is in a class by itself.
