C++ implementation of my python project https://github.com/JuanPabloZed/IR_Maker (deprecated).
Does the same thing as Voxengo's Deconvolver (https://www.voxengo.com/product/deconvolver/), but for free and with more features (IR visualisation, a nice interface...).

Go to your IR Maker installation folder (where you chose to install it with the setup executable, mostly in Program Files or Program Files (x86)), and run the unins0000.exe to uninstall previous version. Then, get the latest release on this github and run it !
This application is based on the use of Angelo Farina's ESS method. To sum up, the ESS method consists in the following :
1- Generate an exponential sine sweep (ESS) signal through IR Maker
2- Play the ESS through a speaker, a guitar cab, a room if you want its reverb, anything you want to characterize/capture
3- Record the response of the ESS through the system you want to capture
4- Launch IR Maker and let it guide you through the process !
Important note : the software only supports 16, 24 & 32 bit PCM WAV files.
To get all the features, be sure to run the app as administrator if you're not logged in with an administrator session
- Automatic output saving for fast workflow AND custom saving option
- Custom the IR's length, in ms or samples
- Pre-ringing cut option (can be disabled if you want to experiment and get the full raw output)
- 16, 24, 32 bit PCM output options
- Visual tools for a direct analysis of the IRs (waveform, spectrum, hidable if wanted)
- Hear the IRs directly or through an audio file of your choice (if longer than 10sec, will be truncated at 10sec)
- Multiple IRs rendering at once (batch rendering) : simply select the files you want to process
- SWEEP GENERATOR
- Customable beginning & ending frequencies (possible to make a decreasing sweep e.g. for a bass drop, but for IR making it HAS to be increasing)
- Fade-in/fade-out option
- Sample rates from 44,1kHz to 192kHz
- Waveform visualisation
- Use a sweep that goes up to your Nyquist frequency, i.e. half of the sample rate, instead of stopping at 20kHz (use the "full frequency range" boxes to do it for you !)
- Use the same sample rate for both the sweep AND the response
- Use the same bit depth for both the sweep AND the response
- For a cab IR, use a mono file for the response
Just get the latest release (Windows only for now) ! For now it might still be buggy so feel free to report any error/problem/bug, but it is proven to do its main job : make accurate IRs.
If you want to work on your own version of this code, this works with the QT framework in C++ so you won't be able to run the app without QT libraries.
